A review of The Age of Em by Robin Hanson

In the Dune series, the Butlerian Jihad was a holy war against artificial intelligence that resulted in a millenias-long taboo against all forms of intelligent machines. It was effectively a way to tell a story about the distant future without basically everything being about robots or cyborgs.

After reading Robin Hanson’s book, I’m starting to think that maybe we should actually do it.

Thus it is written: “Thou shalt not make a machine in the likeness of a human mind.”

Hanson says he’s trying to reserve judgment and present objective predictions without evaluation, but it becomes very clear throughout that this is the future he wants, as well as—or perhaps even instead of—the world he expects.

In many ways, it feels like he has done his very best to imagine a world of true neoclassical rational agents in perfect competition, a sort of sandbox for the toys he’s always wanted to play with. Throughout he very much takes the approach of a neoclassical economist, making heroic assumptions and then following them to their logical conclusions, without ever seriously asking whether those assumptions actually make any sense.

To his credit, Hanson does not buy into the hype that AGI will be successful any day now. He predicts that we will achieve the ability to fully emulate human brains and thus create a sort of black-box AGI that behaves very much like a human within about 100 years. Given how the Blue Brain Project has progressed (much slower than its own hype machine told us it would—and let it be noted that I predicted this from the very beginning), I think this is a fairly plausible time estimate. He refers to a mind emulated in this way as an “em”; I have mixed feelings about the term, but I suppose we did need some word for that, and it certainly has conciseness on its side.

Hanson believes that a true understanding of artificial intelligence will only come later, and the sort of AGI that can be taken apart and reprogrammed for specific goals won’t exist for at least a century after that. Both of these sober, reasonable predictions are deeply refreshing in a field that’s been full of people saying “any day now” for the last fifty years.

But Hanson’s reasonableness just about ends there.

In The Age of Em, government is exactly as strong as Hanson needs it to be. Somehow it simultaneously ensures a low crime rate among a population that doubles every few months while also having no means of preventing that population growth. Somehow ensures that there is no labor collusion and corporations never break the law, but without imposing any regulations that might reduce efficiency in any way.

All of this begins to make more sense when you realize that Hanson’s true goal here is to imagine a world where neoclassical economics is actually true.

He realized it didn’t work on humans, so instead of giving up the theory, he gave up the humans.

Hanson predicts that ems will casually make short-term temporary copies of themselves called “spurs”, designed to perform a particular task and then get erased. I guess maybe he would, but I for one would not so cavalierly create another person and then make their existence dedicated to doing a single job before they die. The fact that I created this person, and they are very much like me, seem like reasons to care more about their well-being, not less! You’re asking me to enslave and murder my own child. (Honestly, the fact that Robin Hanson thinks ems will do this all the time says more about Robin Hanson than anything else.) Any remotely sane society of ems would ban the deletion of another em under any but the most extreme circumstances, and indeed treat it as tantamount to murder.

Hanson predicts that we will only copy the minds of a few hundred people. This is surely true at some point—the technology will take time to develop, and we’ll have to start somewhere. But I don’t see why we’d stop there, when we could continue to copy millions or billions of people; and his choices of who would be emulated, while not wildly implausible, are utterly terrifying.

He predicts that we’d emulate genius scientists and engineers; okay, fair enough, that seems right. I doubt that the benefits of doing so will be as high as many people imagine, because scientific progress actually depends a lot more on the combined efforts of millions of scientists than on rare sparks of brilliance by lone geniuses; but those people are definitely very smart, and having more of them around could be a good thing. I can also see people wanting to do this, and thus investing in making it happen.

He also predicts that we’d emulate billionaires. Now, as a prediction, I have to admit that this is actually fairly plausible; billionaires are precisely the sort of people who are rich enough to pay to be emulated and narcissistic enough to want to. But where Hanson really goes off the deep end here is that he sees this as a good thing. He seems to honestly believe that billionaires are so rich because they are so brilliant and productive. He thinks that a million copies of Elon Musks would produce a million hectobillionaires—when in reality it would produce a million squabbling narcissists, who at best had to split the same $200 billion wealth between them, and might very well end up with less because they squander it.

Hanson has a long section on trying to predict the personalities of ems. Frankly this could just have been dropped entirely; it adds almost nothing to the book, and the book is much too long. But the really striking thing to me about that section is what isn’t there. He goes through a long list of studies that found weak correlations between various personality traits like extroversion or openness and wealth—mostly comparing something like the 20th percentile to the 80th percentile—and then draws sweeping conclusions about what ems will be like, under the assumption that ems are all drawn from people in the 99.99999th percentile. (Yes, upper-middle-class people are, on average, more intelligent and more conscientious than lower-middle-class people. But do we even have any particular reason to think that the personalities of people who make $150,000 are relevant to understanding the behavior of people who make $15 billion?) But he completely glosses over the very strong correlations that specifically apply to people in that very top super-rich class: They’re almost all narcissists and/or psychopaths.

Hanson predicts a world where each em is copied many, many times—millions, billions, even trillions of times, and also in which the very richest ems are capable of buying parallel processing time that lets them accelerate their own thought processes to a million times faster than a normal human. (Is that even possible? Does consciousness work like that? Who knows!?) The world that Hanson is predicting is thus one where all the normal people get outnumbered and overpowered by psychopaths.

Basically this is the most abjectly dystopian cyberpunk hellscape imaginable. And he talks about it the whole time as if it were good.

It’s like he played the game Action Potential and thought, “This sounds great! I’d love to live there!” I mean, why wouldn’t you want to owe a life-debt on your own body and have to work 120-hour weeks for a trillion-dollar corporation just to make the payments on it?

Basically, Hanson doesn’t understand how wealth is actually acquired. He is educated as an economist, yet his understanding of capitalism basically amounts to believing in magic. He thinks that competitive markets just somehow perfectly automatically allocate wealth to whoever is most productive, and thus concludes that whoever is wealthy now must just be that productive.

I can see no other way to explain his wildly implausible predictions that the em economy will double every month or two. A huge swath of the book depends upon this assumption, but he waits until halfway through the book to even try to defend it, and then does an astonishingly bad job of doing so. (Honestly, even if you buy his own arguments—which I don’t—they seem to predict that population would grow with Moore’s Law—doubling every couple of years, not every couple of months.)

Whereas Keynes predicted based on sound economic principles that economic growth would more or less proceed apace and got his answer spot-on, Hanson predicts that for mysterious, unexplained reasons economic growth will suddenly increase by two orders of magnitude—and I’m pretty sure he’s going to be wildly wrong.

Hanson also predicts that ems will be on average poorer than we are, based on some sort of perfect-competition argument that doesn’t actually seem to mesh at all with his predictions of spectacularly rapid economic and technological growth. I think the best way to make sense of this is to assume that it means the trend toward insecure affluence will continue: Ems will have an objectively high standard of living in terms of what they own, what games they play, where they travel, and what they eat and drink (in simulation), but they will constantly be struggling to keep up with the rent on their homes—or even their own bodies. This is a world where (the very finest simulation of) Dom Perignon is $7 a bottle and wages are $980 an hour—but monthly rent is $284,000.

Early in the book Hanson argues that this life of poverty and scarcity will lead to more conservative values, on the grounds that people who are poorer now seem to be more conservative, and this has something to do with farmers versus foragers. Hanson’s explanation of all this is baffling; I will quote it at length, just so it’s clear I’m not misrepresenting it:

The other main (and independent) axis of value variation ranges between poor and rich societies. Poor societies place more value on conformity, security, and traditional values such as marriage, heterosexuality, religion, patriotism, hard work, and trust in authority. In contrast, rich societies place more value on individualism, self-direction, tolerance, pleasure, nature, leisure, and trust. When the values of individuals within a society vary on the same axis, we call this a left/liberal (rich) versus right/conservative (poor) axis.

Foragers tend to have values more like those of rich/liberal people today, while subsistence farmers tend to have values more like those of poor/conservative people today. As industry has made us richer, we have on average moved from conservative/farmer values to liberal/forager values. This value movement can make sense if cultural evolution used the social pressures farmers faced, such as conformity and religion, to induce humans, who evolved to find forager behaviors natural, to instead act like farmers. As we become rich, we don’t as strongly fear the threats behind these social pressures. This connection may result in part from disease; rich people are healthier, and healthier societies fear less.

The alternate theory that we have instead learned that rich forager values are more true predicts that values should have followed a random walk over time, and be mostly common across space. It also predicts the variance of value changes tracking the rate at which relevant information appears. But in fact industrial-era value changes have tracked the wealth of each society in much more steady and consistent fashion. And on this theory, why did foragers ever acquire farmer values?

[…]

In the scenario described in this book, many strange-to-forager behaviors are required, and median per-person (i.e. per-em) incomes return to near-subsistence levels. This suggests that the em era may reverse the recent forager-like trend toward more liberality; ems may have more farmer-like values.

The Age of Em, p. 26-27

There’s a lot to unpack here, but maybe it’s better to burn the whole suitcase.

First of all, it’s not entirely clear that this is really a single axis of variation, that foragers and farmers differ from each other in the same way as liberals and conservatives. There’s some truth to that at least—both foragers and liberals tend to be more generous, both farmers and conservatives tend to enforce stricter gender norms. But there are also clear ways that liberal values radically deviate from forager values: Forager societies are extremely xenophobic, and typically very hostile to innovation, inequality, or any attempts at self-aggrandizement (a phenomenon called “fierce egalitarianism“). San Francisco epitomizes rich, liberal values, but it would be utterly alien and probably regarded as evil by anyone from the Yanomamo.

Second, there is absolutely no reason to predict any kind of random walk. That’s just nonsense. Would you predict that scientific knowledge is a random walk, with each new era’s knowledge just a random deviation from the last’s? Maybe next century we’ll return to geocentrism, or phrenology will be back in vogue? On the theory that liberal values (or at least some liberal values) are objectively correct, we would expect them to advance as knowledge does—improving over time, and improving faster in places that have better institutions for research, education, and free expression. And indeed, this is precisely the pattern we have observed. (Those places are also richer, but that isn’t terribly surprising either!)

Third, while poorer regions are indeed more conservative, poorer people within a region actually tend to be more liberal. Nigeria is poorer and more conservative than Norway, and Mississippi is poorer and more conservative than Massachusetts. But higher-income households in the United States are more likely to vote Republican. I think this is particularly true of people living under insecure affluence: We see the abundance of wealth around us, and don’t understand why we can’t learn to share it better. We’re tired of fighting over scraps while the billionaires claim more and more. Millennials and Zoomers absolutely epitomize insecure affluence, and we also absolutely epitomize liberalism. So, if indeed ems live a life of insecure affluence, we should expect them to be like Zoomers: “Trans liberation now!” and “Eat the rich!” (Or should I say, “Delete the rich!”)

And really, doesn’t that make more sense? Isn’t that the trend our society has been on, for at least the last century? We’ve been moving toward more and more acceptance of women and minorities, more and more deviation from norms, more and more concern for individual rights and autonomy, more and more resistance to authority and inequality.

The funny thing is, that world sounds a lot better than the one Hanson is predicting.

A world of left-wing ems would probably run things a lot better than Hanson imagines: Instead of copying the same hundred psychopaths over and over until we fill the planet, have no room for anything else, and all struggle to make enough money just to stay alive, we could moderate our population to a more sustainable level, preserve diversity and individuality, and work toward living in greater harmony with each other and the natural world. We could take this economic and technological abundance and share it and enjoy it, instead of killing ourselves and each other to make more of it for no apparent reason.

The one good argument Hanson makes here is expressed in a single sentence: “And on this theory, why did foragers ever acquire farmer values?” That actually is a good question; why did we give up on leisure and egalitarianism when we transitioned from foraging to agriculture?

I think scarcity probably is relevant here: As food became scarcer, maybe because of climate change, people were forced into an agricultural lifestyle just to have enough to eat. Early agricultural societies were also typically authoritarian and violent. Under those conditions, people couldn’t be so generous and open-minded; they were surrounded by threats and on the verge of starvation.

I guess if Hanson is right that the em world is also one of poverty and insecurity, we might go back to those sort of values, borne of desperation. But I don’t see any reason to think we’d give up all of our liberal values. I would predict that ems will still be feminist, for instance; in fact, Hanson himself admits that since VR avatars would let us change gender presentation at will, gender would almost certainly become more fluid in a world of ems. Far from valuing heterosexuality more highly (as conservatives do, a “farmer value” according to Hanson), I suspect that ems will have no further use for that construct, because reproduction will be done by manufacturing, not sex, and it’ll be so easy to swap your body into a different one that hardly anyone will even keep the same gender their whole life. They’ll think it’s quaint that we used to identify so strongly with our own animal sexual dimorphism.

But maybe it is true that the scarcity induced by a hyper-competitive em world would make people more selfish, less generous, less trusting, more obsessed with work. Then let’s not do that! We don’t have to build that world! This isn’t a foregone conclusion!

There are many other paths yet available to us.

Indeed, perhaps the simplest would be to just ban artificial intelligence, at least until we can get a better handle on what we’re doing—and perhaps until we can institute the kind of radical economic changes necessary to wrest control of the world away from the handful of psychopaths currently trying their best to run it into the ground.

I admit, it would kind of suck to not get any of the benefits of AI, like self-driving cars, safer airplanes, faster medical research, more efficient industry, and better video games. It would especially suck if we did go full-on Butlerian Jihad and ban anything more complicated than a pocket calculator. (Our lifestyle might have to go back to what it was in—gasp! The 1950s!)

But I don’t think it would suck nearly as much as the world Robin Hanson thinks is in store for us if we continue on our current path.

So I certainly hope he’s wrong about all this.

Fortunately, I think he probably is.

We do seem to have better angels after all

A review of The Darker Angels of Our Nature

(I apologize for not releasing this on Sunday; I’ve been traveling lately and haven’t found much time to write.)

Since its release, I have considered Steven Pinker’s The Better Angels of our Nature among a small elite category of truly great books—not simply good because enjoyable, informative, or well-written, but great in its potential impact on humanity’s future. Others include The General Theory of Employment, Interest, and Money, On the Origin of Species, and Animal Liberation.

But I also try to expose myself as much as I can to alternative views. I am quite fearful of the echo chambers that social media puts us in, where dissent is quietly hidden from view and groupthink prevails.

So when I saw that a group of historians had written a scathing critique of The Better Angels, I decided I surely must read it and get its point of view. This book is The Darker Angels of Our Nature.

The Darker Angels is written by a large number of different historians, and it shows. It’s an extremely disjointed book; it does not present any particular overall argument, various sections differ wildly in scope and tone, and sometimes they even contradict each other. It really isn’t a book in the usual sense; it’s a collection of essays whose only common theme is that they disagree with Steven Pinker.

In fact, even that isn’t quite true, as some of the best essays in The Darker Angels are actually the ones that don’t fundamentally challenge Pinker’s contention that global violence has been on a long-term decline for centuries and is now near its lowest in human history. These essays instead offer interesting insights into particular historical eras, such as medieval Europe, early modern Russia, and shogunate Japan, or they add additional nuances to the overall pattern, like the fact that, compared to medieval times, violence in Europe seems to have been less in the Pax Romana (before) and greater in the early modern period (after), showing that the decline in violence was not simple or steady, but went through fluctuations and reversals as societies and institutions changed. (At this point I feel I should note that Pinker clearly would not disagree with this—several of the authors seem to think he would, which makes me wonder if they even read The Better Angels.)

Others point out that the scale of civilization seems to matter, that more is different, and larger societies and armies more or less automatically seem to result in lower fatality rates by some sort of scaling or centralization effect, almost like the square-cube law. That’s very interesting if true; it would suggest that in order to reduce violence, you don’t really need any particular mode of government, you just need something that unites as many people as possible under one banner. The evidence presented for it was too weak for me to say whether it’s really true, however, and there was really no theoretical mechanism proposed whatsoever.

Some of the essays correct genuine errors Pinker made, some of which look rather sloppy. Pinker clearly overestimated the death tolls of the An Lushan Rebellion, the Spanish Inquisition, and Aztec ritual executions, probably by using outdated or biased sources. (Though they were all still extremely violent!) His depiction of indigenous cultures does paint with a very broad brush, and fails to recognize that some indigenous societies seem to have been quite peaceful (though others absolutely were tremendously violent).

One of the best essays is about Pinker’s cavalier attitude toward mass incarceration, which I absolutely do consider a deep flaw in Pinker’s view. Pinker presents increased incarceration rates along with decreased crime rates as if they were an unalloyed good, while I can at best be ambivalent about whether the benefit of decreasing crime is worth the cost of greater incarceration. Pinker seems to take for granted that these incarcerations are fair and impartial, when we have a great deal of evidence that they are strongly biased against poor people and people of color.

There’s another good essay about the Enlightenment, which Pinker seems to idealize a little too much (especially in his other book Enlightenment Now). There was no sudden triumph of reason that instantly changed the world. Human knowledge and rationality gradually improved over a very long period of time, with no obvious turning point and many cases of backsliding. The scientific method isn’t a simple, infallible algorithm that suddenly appeared in the brain of Galileo or Bayes, but a whole constellation of methods and concepts of rationality that took centuries to develop and is in fact still developing. (Much as the Tao that can be told is not the eternal Tao, the scientific method that can be written in a textbook is not the true scientific method.)

Several of the essays point out the limitations of historical and (especially) archaeological records, making it difficult to draw any useful inferences about rates of violence in the past. I agree that Pinker seems a little too cavalier about this; the records really are quite sparse and it’s not easy to fill in the gaps. Very small samples can easily distort homicide rates; since only about 1% of deaths worldwide are homicide, if you find 20 bodies, whether or not one of them was murdered is the difference between peaceful Japan and war-torn Colombia.

On the other hand, all we really can do is make the best inferences we have with the available data, and for the time periods in which we do have detailed records—surely true since at least the 19th century—the pattern of declining violence is very clear, and even the World Wars look like brief fluctuations rather than fundamental reversals. Contrary to popular belief, the World Wars do not appear to have been especially deadly on a per-capita basis, compared to various historic wars. The primary reason so many people died in the World Wars was really that there just were more people in the world. A few of the authors don’t seem to consider this an adequate reason, but ask yourself this: Would you rather live in a society of 100 in which 10 people are killed, or a society of 1 billion in which 1 million are killed? In the former case your chances of being killed are 10%; in the latter, 0.1%. Clearly, per-capita measures of violence are the correct ones.

Some essays seem a bit beside the point, like one on “environmental violence” which quite aptly details the ongoing—terrifying—degradation of our global ecology, but somehow seems to think that this constitutes violence when it obviously doesn’t. There is widespread violence against animals, certainly; slaughterhouses are the obvious example—and unlike most people, I do not consider them some kind of exception we can simply ignore. We do in fact accept levels of cruelty to pigs and cows that we would never accept against dogs or horses—even the law makes such exceptions. Moreover, plenty of habitat destruction is accompanied by killing of the animals who lived in that habitat. But ecological degradation is not equivalent to violence. (Nor is it clear to me that our treatment of animals is more violent overall today than in the past; I guess life is probably worse for a beef cow today than it was in the medieval era, but either way, she was going to be killed and eaten. And at least we no longer do cat-burning.) Drilling for oil can be harmful, but it is not violent. We can acknowledge that life is more peaceful now than in the past without claiming that everything is better now—in fact, one could even say that overall life isn’t better, but I think they’d be hard-pressed to argue that.

These are the relatively good essays, which correct minor errors or add interesting nuances. There are also some really awful essays in the mix.

A common theme of several of the essays seems to be “there are still bad things, so we can’t say anything is getting better”; they will point out various forms of violence that undeniably still exist, and treat this as a conclusive argument against the claim that violence has declined. Yes, modern slavery does exist, and it is a very serious problem; but it clearly is not the same kind of atrocity that the Atlantic slave trade was. Yes, there are still murders. Yes, there are still wars. Probably these things will always be with us to some extent; but there is a very clear difference between 500 homicides per million people per year and 50—and it would be better still if we could bring it down to 5.

There’s one essay about sexual violence that doesn’t present any evidence whatsoever to contradict the claim that rates of sexual violence have been declining while rates of reporting and prosecution have been increasing. (These two trends together often result in reported rapes going up, but most experts agree that actual rapes are going down.) The entire essay is based on anecdote, innuendo, and righteous anger.

There are several essays that spend their whole time denouncing neoliberal capitalism (not even presenting any particularly good arguments against it, though such arguments do exist), seeming to equate Pinker’s view with some kind of Rothbardian anarcho-capitalism when in fact Pinker is explictly in favor of Nordic-style social democracy. (One literally dismisses his support for universal healthcare as “Well, he is Canadian”.) But Pinker has on occasion said good things about capitalism, so clearly, he is an irredeemable monster.

Right in the introduction—which almost made me put the book down—is an astonishingly ludicrous argument, which I must quote in full to show you that it is not out of context:

What actually is violence (nowhere posed or answered in The Better Angels)? How do people perceive it in different time-place settings? What is its purpose and function? What were contemporary attitudes toward violence and how did sensibilities shift over time? Is violence always ‘bad’ or can there be ‘good’ violence, violence that is regenerative and creative?

The Darker Angels of Our Nature, p.16

Yes, the scare quotes on ‘good’ and ‘bad’ are in the original. (Also the baffling jargon “time-place settings” as opposed to, say, “times and places”.) This was clearly written by a moral relativist. Aside from questioning whether we can say anything about anything, the argument seems to be that Pinker’s argument is invalid because he didn’t precisely define every single relevant concept, even though it’s honestly pretty obvious what the world “violence” means and how he is using it. (If anything, it’s these authors who don’t seem to understand what the word means; they keep calling things “violence” that are indeed bad, but obviously aren’t violence—like pollution and cyberbullying. At least talk of incarceration as “structural violence” isn’t obvious nonsense—though it is still clearly distinct from murder rates.)

But it was by reading the worst essays that I think I gained the most insight into what this debate is really about. Several of the essays in The Darker Angels thoroughly and unquestioningly share the following inference: if a culture is superior, then that culture has a right to impose itself on others by force. On this, they seem to agree with the imperialists: If you’re better, that gives you a right to dominate everyone else. They rightly reject the claim that cultures have a right to imperialistically dominate others, but they cannot deny the inference, and so they are forced to deny that any culture can ever be superior to another. The result is that they tie themselves in knots trying to justify how greater wealth, greater happiness, less violence, and babies not dying aren’t actually good things. They end up talking nonsense about “violence that is regenerative and creative”.

But we can believe in civilization without believing in colonialism. And indeed that is precisely what I (along with Pinker) believe: That democracy is better than autocracy, that free speech is better than censorship, that health is better than illness, that prosperity is better than poverty, that peace is better than war—and therefore that Western civilization is doing a better job than the rest. I do not believe that this justifies the long history of Western colonial imperialism. Governing your own country well doesn’t give you the right to invade and dominate other countries. Indeed, part of what makes colonial imperialism so terrible is that it makes a mockery of the very ideals of peace, justice, and freedom that the West is supposed to represent.

I think part of the problem is that many people see the world in zero-sum terms, and believe that the West’s prosperity could only be purchased by the rest of the world’s poverty. But this is untrue. The world is nonzero-sum. My happiness does not come from your sadness, and my wealth does not come from your poverty. In fact, even the West was poor for most of history, and we are far more prosperous now that we have largely abandoned colonial imperialism than we ever were in imperialism’s heyday. (I do occasionally encounter British people who seem vaguely nostalgic for the days of the empire, but real median income in the UK has doubled just since 1977. Inequality has also increased during that time, which is definitely a problem; but the UK is undeniably richer now than it ever was at the peak of the empire.)

In fact it could be that the West is richer now because of colonalism than it would have been without it. I don’t know whether or not this is true. I suspect it isn’t, but I really don’t know for sure. My guess would be that colonized countries are poorer, but colonizer countries are not richer—that is, colonialism is purely destructive. Certain individuals clearly got richer by such depredation (Leopold II, anyone?), but I’m not convinced many countries did.

Yet even if colonialism did make the West richer, it clearly cannot explain most of the wealth of Western civilization—for that wealth simply did not exist in the world before. All these bridges and power plants, laptops and airplanes weren’t lying around waiting to be stolen. Surely, some of the ingredients were stolen—not least, the land. Had they been bought at fair prices, the result might have been less wealth for us (then again it might not, for wealthier trade partners yield greater exports). But this does not mean that the products themselves constitute theft, nor that the wealth they provide is meaningless. Perhaps we should find some way to pay reparations; undeniably, we should work toward greater justice in the future. But we do not need to give up all we have in order to achieve that justice.

There is a law of conservation of energy. It is impossible to create energy in one place without removing it from another. There is no law of conservation of prosperity. Making the world better in one place does not require making it worse in another.

Progress is real. Yes, it is flawed, uneven, and it has costs of its own; but it is real. If we want to have more of it, we best continue to believe in it. And The Better Angels of Our Nature does have some notable flaws, but it still retains its place among truly great books.

A review of Homo Deus

The real problem of humanity is the following: We have Paleolithic emotions, medieval institutions and godlike technology.

E.O. Wilson

Homo Deus is a very good read—and despite its length, a quick one; as you can see, I read it cover to cover in a week. Yuval Noah Harari’s central point is surely correct: Our technology is reaching a threshold where it grants us unprecedented power and forces us to ask what it means to be human.

Biotechnology and artificial intelligence are now advancing so rapidly that advancements in other domains, such as aerospace and nuclear energy, seem positively mundane. Who cares about making flight or electricity a bit cleaner when we will soon have the power to modify ourselves or we’ll all be replaced by machines?

Indeed, we already have technology that would have seemed to ancient people like the powers of gods. We can fly; we can witness or even control events thousands of miles away; we can destroy mountains; we can wipeout entire armies in an instant; we can even travel into outer space.

Harari rightly warns us that our not-so-distant descendants are likely to have powers that we would see as godlike: Immortality, superior intelligence, self-modification, the power to create life.

And where it is scary to think about what they might do with that power if they think the way we do—as ignorant and foolish and tribal as we are—Harari points out that it is equally scary to think about what they might do if they don’t think the way we do—for then, how do they think? If their minds are genetically modified or even artificially created, who will they be? What values will they have, if not ours? Could they be better? What if they’re worse?

It is of course difficult to imagine values better than our own—if we thought those values were better, we’d presumably adopt them. But we should seriously consider the possibility, since presumably most of us believe that our values today are better than what most people’s values were 1000 years ago. If moral progress continues, does it not follow that people’s values will be better still 1000 years from now? Or at least that they could be?

I also think Harari overestimates just how difficult it is to anticipate the future. This may be a useful overcorrection; the world is positively infested with people making overprecise predictions about the future, often selling them for exorbitant fees (note that Harari was quite well-compensated for this book as well!). But our values are not so fundamentally alien from those of our forebears, and we have reason to suspect that our descendants’ values will be no more different from ours.

For instance, do you think that medieval people thought suffering and death were good? I assure you they did not. Nor did they believe that the supreme purpose in life is eating cheese. (They didn’t even believe the Earth was flat!) They did not have the concept of GDP, but they could surely appreciate the value of economic prosperity.

Indeed, our world today looks very much like a medieval peasant’s vision of paradise. Boundless food in endless variety. Near-perfect security against violence. Robust health, free from nearly all infectious disease. Freedom of movement. Representation in government! The land of milk and honey is here; there they are, milk and honey on the shelves at Walmart.

Of course, our paradise comes with caveats: Not least, we are by no means free of toil, but instead have invented whole new kinds of toil they could scarcely have imagined. If anything I would have to guess that coding a robot or recording a video lecture probably isn’t substantially more satisfying than harvesting wheat or smithing a sword; and reconciling receivables and formatting spreadsheets is surely less. Our tasks are physically much easier, but mentally much harder, and it’s not obvious which of those is preferable. And we are so very stressed! It’s honestly bizarre just how stressed we are, given the abudance in which we live; there is no reason for our lives to have stakes so high, and yet somehow they do. It is perhaps this stress and economic precarity that prevents us from feeling such joy as the medieval peasants would have imagined for us.

Of course, we don’t agree with our ancestors on everything. The medieval peasants were surely more religious, more ignorant, more misogynistic, more xenophobic, and more racist than we are. But projecting that trend forward mostly means less ignorance, less misogyny, less racism in the future; it means that future generations should see the world world catch up to what the best of us already believe and strive for—hardly something to fear. The values that I believe are surely not what we as a civilization act upon, and I sorely wish they were. Perhaps someday they will be.

I can even imagine something that I myself would recognize as better than me: Me, but less hypocritical. Strictly vegan rather than lacto-ovo-vegetarian, or at least more consistent about only buying free range organic animal products. More committed to ecological sustainability, more willing to sacrifice the conveniences of plastic and gasoline. Able to truly respect and appreciate all life, even humble insects. (Though perhaps still not mosquitoes; this is war. They kill more of us than any other animal, including us.) Not even casually or accidentally racist or sexist. More courageous, less burnt out and apathetic. I don’t always live up to my own ideals. Perhaps someday someone will.

Harari fears something much darker, that we will be forced to give up on humanist values and replace them with a new techno-religion he calls Dataism, in which the supreme value is efficient data processing. I see very little evidence of this. If it feels like data is worshipped these days, it is only because data is profitable. Amazon and Google constantly seek out ever richer datasets and ever faster processing because that is how they make money. The real subject of worship here is wealth, and that is nothing new. Maybe there are some die-hard techno-utopians out there who long for us all to join the unified oversoul of all optimized data processing, but I’ve never met one, and they are clearly not the majority. (Harari also uses the word ‘religion’ in an annoyingly overbroad sense; he refers to communism, liberalism, and fascism as ‘religions’. Ideologies, surely; but religions?)

Harari in fact seems to think that ideologies are strongly driven by economic structures, so maybe he would even agree that it’s about profit for now, but thinks it will become religion later. But I don’t really see history fitting this pattern all that well. If monotheism is directly tied to the formation of organized bureaucracy and national government, then how did Egypt and Rome last so long with polytheistic pantheons? If atheism is the natural outgrowth of industrialized capitalism, then why are Africa and South America taking so long to get the memo? I do think that economic circumstances can constrain culture and shift what sort of ideas become dominant, including religious ideas; but there clearly isn’t this one-to-one correspondence he imagines. Moreover, there was never Coalism or Oilism aside from the greedy acquisition of these commodities as part of a far more familiar ideology: capitalism.

He also claims that all of science is now, or is close to, following a united paradigm under which everything is a data processing algorithm, which suggests he has not met very many scientists. Our paradigms remain quite varied, thank you; and if they do all have certain features in common, it’s mainly things like rationality, naturalism and empiricism that are more or less inherent to science. It’s not even the case that all cognitive scientists believe in materialism (though it probably should be); there are still dualists out there.

Moreover, when it comes to values, most scientists believe in liberalism. This is especially true if we use Harari’s broad sense (on which mainline conservatives and libertarians are ‘liberal’ because they believe in liberty and human rights), but even in the narrow sense of center-left. We are by no means converging on a paradigm where human life has no value because it’s all just data processing; maybe some scientists believe that, but definitely not most of us. If scientists ran the world, I can’t promise everything would be better, but I can tell you that Bush and Trump would never have been elected and we’d have a much better climate policy in place by now.

I do share many of Harari’s fears of the rise of artificial intelligence. The world is clearly not ready for the massive economic disruption that AI is going to cause all too soon. We still define a person’s worth by their employment, and think of ourselves primarily as collection of skills; but AI is going to make many of those skills obsolete, and may make many of us unemployable. It would behoove us to think in advance about who we truly are and what we truly want before that day comes. I used to think that creative intellectual professions would be relatively secure; ChatGPT and Midjourney changed my mind. Even writers and artists may not be safe much longer.

Harari is so good at sympathetically explaining other views he takes it to a fault. At times it is actually difficult to know whether he himself believes something and wants you to, or if he is just steelmanning someone else’s worldview. There’s a whole section on ‘evolutionary humanism’ where he details a worldview that is at best Nietschean and at worst Nazi, but he makes it sound so seductive. I don’t think it’s what he believes, in part because he has similarly good things to say about liberalism and socialism—but it’s honestly hard to tell.

The weakest part of the book is when Harari talks about free will. Like most people, he just doesn’t get compatibilism. He spends a whole chapter talking about how science ‘proves we have no free will’, and it’s just the same old tired arguments hard determinists have always made.

He talks about how we can make choices based on our desires, but we can’t choose our desires; well of course we can’t! What would that even mean? If you could choose your desires, what would you choose them based on, if not your desires? Your desire-desires? Well, then, can you choose your desire-desires? What about your desire-desire-desires?

What even is this ultimate uncaused freedom that libertarian free will is supposed to consist in? No one seems capable of even defining it. (I’d say Kant got the closest: He defined it as the capacity to act based upon what ought rather than what is. But of course what we believe about ‘ought’ is fundamentally stored in our brains as a particular state, a way things are—so in the end, it’s an ‘is’ we act on after all.)

Maybe before you lament that something doesn’t exist, you should at least be able to describe that thing as a coherent concept? Woe is me, that 2 plus 2 is not equal to 5!

It is true that as our technology advances, manipulating other people’s desires will become more and more feasible. Harari overstates the case on so-called robo-rats; they aren’t really mind-controlled, it’s more like they are rewarded and punished. The rat chooses to go left because she knows you’ll make her feel good if she does; she’s still freely choosing to go left. (Dangling a carrot in front of a horse is fundamentally the same thing—and frankly, paying a wage isn’t all that different.) The day may yet come where stronger forms of control become feasible, and woe betide us when it does. Yet this is no threat to the concept of free will; we already knew that coercion was possible, and mind control is simply a more precise form of coercion.

Harari reports on a lot of interesting findings in neuroscience, which are important for people to know about, but they do not actually show that free will is an illusion. What they do show is that free will is thornier than most people imagine. Our desires are not fully unified; we are often ‘of two minds’ in a surprisingly literal sense. We are often tempted by things we know are wrong. We often aren’t sure what we really want. Every individual is in fact quite divisible; we literally contain multitudes.

We do need a richer account of moral responsibility that can deal with the fact that human beings often feel multiple conflicting desires simultaneously, and often experience events differently than we later go on to remember them. But at the end of the day, human consciousness is mostly unified, our choices are mostly rational, and our basic account of moral responsibility is mostly valid.

I think for now we should perhaps be less worried about what may come in the distant future, what sort of godlike powers our descendants may have—and more worried about what we are doing with the godlike powers we already have. We have the power to feed the world; why aren’t we? We have the power to save millions from disease; why don’t we? I don’t see many people blindly following this ‘Dataism’, but I do see an awful lot blinding following a 19th-century vision of capitalism.

And perhaps if we straighten ourselves out, the future will be in better hands.

Why does democracy work?

A review of Democracy for Realists

I don’t think it can be seriously doubted that democracy does, in fact, work. Not perfectly, by any means; but the evidence is absolutely overwhelming that more democratic societies are better than more authoritarian societies by just about any measure you could care to use.

When I first started reading Democracy for Realists and saw their scathing, at times frothing criticism of mainstream ideas of democracy, I thought they were going to try to disagree with that; but in the end they don’t. Achen and Bartels do agree that democracy works; they simply think that why and how it works is radically different from what most people think.

For it is a very long-winded book, and in dire need of better editing. Most of the middle section of the book is taken up by a deluge of empirical analysis, most of which amounts to over-interpreting the highly ambiguous results of underpowered linear regressions on extremely noisy data. The sheer quantity of them seems intended to overwhelm any realization that no particular one is especially compelling. But a hundred weak arguments don’t add up to a single strong one.

To their credit, the authors often include the actual scatter plots; but when you look at those scatter plots, you find yourself wondering how anyone could be so convinced these effects are real and important. Many of them seem more prone to new constellations.

Their econometric techniques are a bit dubious, as well; at one point they said they “removed outliers” but then the examples they gave as “outliers” were the observations most distant from their regression line rather than the rest of the data. Removing the things furthest from your regression line will always—always—make your regression seem stronger. But that’s not what outliers are. Other times, they add weird controls or exclude parts of the sample for dubious reasons, and I get the impression that these are the cherry-picked results of a much larger exploration. (Why in the world would you exclude Catholics from a study of abortion attitudes? And this study on shark attacks seems awfully specific….) And of course if you try 20 regressions at random, you can expect that at least 1 of them will probably show up with p < 0.05. I think they are mainly just following the norms of their discipline—but those norms are quite questionable.

They don’t ever get into much detail as to what sort of practical institutional changes they would recommend, so it’s hard to know whether I would agree with those. Some of their suggestions, such as more stringent rules on campaign spending, I largely agree with. Others, such as their opposition to popular referenda and recommendation for longer term limits, I have more mixed feelings about. But none seem totally ridiculous or even particularly radical, and they really don’t offer much detail about any of them. I thought they were going to tell me that appointment of judges is better than election (which many experts widely agree), or that the Electoral College is a good system (which far fewer experts would assent to, at least since George W. Bush and Donald Trump). In fact they didn’t do that; they remain eerily silent on substantive questions like this.

Honestly, what little they have to say about institutional policy feels a bit tacked on at the end, as if they suddenly realized that they ought to say something useful rather than just spend the whole time tearing down another theory.

In fact, I came to wonder if they really were tearing down anyone’s actual theory, or if this whole book was really just battering a strawman. Does anyone really think that voters are completely rational? At one point they speak of an image of the ‘sovereign omnicompetent voter’; is that something anyone really believes in?

It does seem like many people believe in making government more responsive to the people, whereas Achen and Bartels seem to have the rather distinct goal of making government make better decisions. They were able to find at least a few examples—though I know not how far and wide they had to search—where it seemed like more popular control resulted in worse outcomes, such as water fluoridation and funding for fire departments. So maybe the real substantive disagreement here is over whether more or less direct democracy is a good idea. And that is indeed a reasonable question. But one need not believe that voters are superhuman geniuses to think that referenda are better than legislation. Simply showing that voters are limited in their capacity and bound to group identity is not enough to answer that question.


In fact, I think that Achen and Bartels seriously overestimate the irrationality of voters, because they don’t seem to appreciate that group identity is often a good proxy for policy—in fact, they don’t even really seem to see social policy as policy at all. Consider this section (p. 238):

“In this pre-Hitlerian age it must have seemed to most Jews that there were no crucial issues dividing the major parties” (Fuchs 1956, 63). Yet by 1923, a very substantial majority of Jews had abandoned their Republican loyalties and begun voting for the Democrats. What had changed was not foreign policy, but rather the social status of Jews within one of America’s major political parties. In a very visible way, the Democrats had become fully accepting and incorporating of religious minorities, both Catholics and Jews. The result was a durable Jewish partisan realignment grounded in “ethnic solidarity”, in Gamm’s characterization.

Gee, I wonder why Jews would suddenly care a great deal which party was more respectful toward people like them? Okay, the Holocaust hadn’t happened yet, but anti-Semitism is very old indeed, and it was visibly creeping upward during that era. And just in general, if one party is clearly more anti-Semitic than the other, why wouldn’t Jews prefer the one that is less hateful toward them? How utterly blinded by privilege do you need to be to not see that this is an important policy difference?

Perhaps because they are both upper-middle-class straight White cisgender men (I would also venture a guess nominally but not devoutly Protestant), Achens and Bartel seem to have no concept that social policy directly affects people of minority identity, that knowing that one party accepts people like you and the other doesn’t is a damn good reason to prefer one over the other. This is not a game where we are rooting for our home team. This directly affects our lives.

I know quite a few transgender people, and not a single one is a Republican. It’s not because all trans people hate low taxes. It’s because the Republican Party has declared war on trans people.

This may also lead to trans people being more left-wing generally, as once you’re in a group you tend to absorb some views from others in that group (and, I’ll admit, Marxists and anarcho-communists seem overrepresented among LGBT people). But I absolutely know some LGBT people who would like to vote conservative for economic policy reasons, but realize they can’t, because it means voting for bigots who hate them and want to actively discriminate against them. There is nothing irrational or even particularly surprising about this choice. It would take a very powerful overriding reason for anyone to want to vote for someone who publicly announces hatred toward them.

Indeed, for me the really baffling thing is that there are political parties that publicly announce hatred toward particular groups. It seems like a really weird strategy for winning elections. That is the thing that needs to be explained here; why isn’t inclusiveness—at least a smarmy lip-service toward inclusiveness, like ‘Diversity, Equity, and Inclusion’ offices at universities—the default behavior of all successful politicians? Why don’t they all hug a Latina trans woman after kissing a baby and taking a selfie with the giant butter cow? Why is not being an obvious bigot considered a left-wing position?

Since it obviously is the case that many voters don’t want this hatred (at the very least, its targets!), in order for it not to damage electoral changes, it must be that some other voters do want this hatred. Perhaps they themselves define their own identity in opposition to other people’s identities. They certainly talk that way a lot: We hear White people fearing ‘replacement‘ by shifting racial demographics, when no sane forecaster thinks that European haplotypes are in any danger of disappearing any time soon. The central argument against gay marriage was always that it would somehow destroy straight marriage, by some mechanism never explained.

Indeed, perhaps it is this very blindness toward social policy that makes Achen and Bartels unable to see the benefits of more direct democracy. When you are laser-focused on economic policy, as they are, then it seems to you as though policy questions are mainly technical matters of fact, and thus what we need are qualified experts. (Though even then, it is not purely a matter of fact whether we should care more about inequality than growth, or more about unemployment than inflation.)

But once you include social policy, you see that politics often involves very real, direct struggles between conflicting interests and differing moral views, and that by the time you’ve decided which view is the correct one, you already have your answer for what must be done. There is no technical question of gay marriage; there is only a moral one. We don’t need expertise on such questions; we need representation. (Then again, it’s worth noting that courts have sometimes advanced rights more effectively than direct democratic votes; so having your interests represented isn’t as simple as getting an equal vote.)

Achen and Bartels even include a model in the appendix where politicians are modeled as either varying in competence or controlled by incentives; never once does it consider that they might differ in whose interests they represent. Yet I don’t vote for a particular politician just because I think they are more intelligent, or as part of some kind of deterrence mechanism to keep them from misbehaving (I certainly hope the courts do a better job of that!); I vote for them because I think they represent the goals and interests I care about. We aren’t asking who is smarter, we are asking who is on our side.

The central question that I think the book raises is one that the authors don’t seem to have much to offer on: If voters are so irrational, why does democracy work? I do think there is strong evidence that voters are irrational, though maybe not as irrational as Achen and Bartels seem to think. Honestly, I don’t see how anyone can watch Donald Trump get elected President of the United States and not think that voters are irrational. (The book was written before that; apparently there’s a new edition with a preface about Trump, but my copy doesn’t have that.) But it isn’t at all obvious to me what to do with that information, because even if so-called elites are in fact more competent than average citizens—which may or may not be true—the fact remains that their interests are never completely aligned. Thus far, representative democracy of one stripe or another seems to be the best mechanism we have for finding people who have sufficient competence while also keeping them on a short enough leash.

And perhaps that’s why democracy works as well as it does; it gives our leaders enough autonomy to let them generally advance their goals, but also places limits on how badly misaligned our leaders’ goals can be from our own.

The mythology mindset

I recently finished reading Steven Pinker’s latest book Rationality. It’s refreshing, well-written, enjoyable, and basically correct with some small but notable errors that seem sloppy—but then you could have guessed all that from the fact that it was written by Steven Pinker.

What really makes the book interesting is an insight Pinker presents near the end, regarding the difference between the “reality mindset” and the “mythology mindset”.

It’s a pretty simple notion, but a surprisingly powerful one.

In the reality mindset, a belief is a model of how the world actually functions. It must be linked to the available evidence and integrated into a coherent framework of other beliefs. You can logically infer from how some parts work to how other parts must work. You can predict the outcomes of various actions. You live your daily life in the reality mindset; you couldn’t function otherwise.

In the mythology mindset, a belief is a narrative that fulfills some moral, emotional, or social function. It’s almost certainly untrue or even incoherent, but that doesn’t matter. The important thing is that it sends the right messages. It has the right moral overtones. It shows you’re a member of the right tribe.

The idea is similar to Dennett’s “belief in belief”, which I’ve written about before; but I think this characterization may actually be a better one, not least because people would be more willing to use it as a self-description. If you tell someone “You don’t really believe in God, you believe in believing in God”, they will object vociferously (which is, admittedly, what the theory would predict). But if you tell them, “Your belief in God is a form of the mythology mindset”, I think they are at least less likely to immediately reject your claim out of hand. “You believe in God a different way than you believe in cyanide” isn’t as obviously threatening to their identity.

A similar notion came up in a Psychology of Religion course I took, in which the professor discussed “anomalous beliefs” linked to various world religions. He picked on a bunch of obscure religions, often held by various small tribes. He asked for more examples from the class. Knowing he was nominally Catholic and not wanting to let mainstream religion off the hook, I presented my example: “This bread and wine are the body and blood of Christ.” To his credit, he immediately acknowledged it as a very good example.

It’s also not quite the same thing as saying that religion is a “metaphor”; that’s not a good answer for a lot of reasons, but perhaps chief among them is that people don’t say they believe metaphors. If I say something metaphorical and then you ask me, “Hang on; is that really true?” I will immediately acknowledge that it is not, in fact, literally true. Love is a rose with all its sweetness and all its thorns—but no, love isn’t really a rose. And when it comes to religious belief, saying that you think it’s a metaphor is basically a roundabout way of saying you’re an atheist.

From all these different directions, we seem to be converging on a single deeper insight: when people say they believe something, quite often, they clearly mean something very different by “believe” than what I would ordinarily mean.

I’m tempted even to say that they don’t really believe it—but in common usage, the word “belief” is used at least as often to refer to the mythology mindset as the reality mindset. (In fact, it sounds less weird to say “I believe in transsubstantiation” than to say “I believe in gravity”.) So if they don’t really believe it, then they at least mythologically believe it.

Both mindsets seem to come very naturally to human beings, in particular contexts. And not just modern people, either. Humans have always been like this.

Ask that psychology professor about Jesus, and he’ll tell you a tall tale of life, death, and resurrection by a demigod. But ask him about the Stroop effect, and he’ll provide a detailed explanation of rigorous experimental protocol. He believes something about God; but he knows something about psychology.

Ask a hunter-gatherer how the world began, and he’ll surely spin you a similarly tall tale about some combination of gods and spirits and whatever else, and it will all be peculiarly particular to his own tribe and no other. But ask him how to gut a fish, and he’ll explain every detail with meticulous accuracy, with almost the same rigor as that scientific experiment. He believes something about the sky-god; but he knows something about fish.

To be a rationalist, then, is to aspire to live your whole life in the reality mindset. To seek to know rather than believe.

This isn’t about certainty. A rationalist can be uncertain about many things—in fact, it’s rationalists of all people who are most willing to admit and quantify their uncertainty.

This is about whether you allow your beliefs to float free as bare, almost meaningless assertions that you profess to show you are a member of the tribe, or you make them pay rent, directly linked to other beliefs and your own experience.

As long as I can remember, I have always aspired to do this. But not everyone does. In fact, I dare say most people don’t. And that raises a very important question: Should they? Is it better to live the rationalist way?

I believe that it is. I suppose I would, temperamentally. But say what you will about the Enlightenment and the scientific revolution, they have clearly revolutionized human civilization and made life much better today than it was for most of human existence. We are peaceful, safe, and well-fed in a way that our not-so-distant ancestors could only dream of, and it’s largely thanks to systems built under the principles of reason and rationality—that is, the reality mindset.

We would never have industrialized agriculture if we still thought in terms of plant spirits and sky gods. We would never have invented vaccines and antibiotics if we still believed disease was caused by curses and witchcraft. We would never have built power grids and the Internet if we still saw energy as a mysterious force permeating the world and not as a measurable, manipulable quantity.

This doesn’t mean that ancient people who saw the world in a mythological way were stupid. In fact, it doesn’t even mean that people today who still think this way are stupid. This is not about some innate, immutable mental capacity. It’s about a technology—or perhaps the technology, the meta-technology that makes all other technology possible. It’s about learning to think the same way about the mysterious and the familiar, using the same kind of reasoning about energy and death and sunlight as we already did about rocks and trees and fish. When encountering something new and mysterious, someone in the mythology mindset quickly concocts a fanciful tale about magical beings that inevitably serves to reinforce their existing beliefs and attitudes, without the slightest shred of evidence for any of it. In their place, someone in the reality mindset looks closer and tries to figure it out.

Still, this gives me some compassion for people with weird, crazy ideas. I can better make sense of how someone living in the modern world could believe that the Earth is 6,000 years old or that the world is ruled by lizard-people. Because they probably don’t really believe it, they just mythologically believe it—and they don’t understand the difference.

Good enough is perfect, perfect is bad

Not too long ago, I read the book How to Keep House While Drowning by KC Davis, which I highly recommend. It offers a great deal of useful and practical advice, especially for someone neurodivergent and depressed living through an interminable pandemic (which I am, but honestly, odds are, you may be too). And to say it is a quick and easy read is actually an unfair understatement; it is explicitly designed to be readable in short bursts by people with ADHD, and it has a level of accessibility that most other books don’t even aspire to and I honestly hadn’t realized was possible. (The extreme contrast between this and academic papers is particularly apparent to me.)

One piece of advice that really stuck with me was this: Good enough is perfect.

At first, it sounded like nonsense; no, perfect is perfect, good enough is just good enough. But in fact there is a deep sense in which it is absolutely true.

Indeed, let me make it a bit stronger: Good enough is perfect; perfect is bad.

I doubt Davis thought of it in these terms, but this is a concise, elegant statement of the principles of bounded rationality. Sometimes it can be optimal not to optimize.

Suppose that you are trying to optimize something, but you have limited computational resources in which to do so. This is actually not a lot for you to suppose—it’s literally true of basically everyone basically every moment of every day.

But let’s make it a bit more concrete, and say that you need to find the solution to the following math problem: “What is the product of 2419 times 1137?” (Pretend you don’t have a calculator, as it would trivialize the exercise. I thought about using a problem you couldn’t do with a standard calculator, but I realized that would also make it much weirder and more obscure for my readers.)

Now, suppose that there are some quick, simple ways to get reasonably close to the correct answer, and some slow, difficult ways to actually get the answer precisely.

In this particular problem, the former is to approximate: What’s 2500 times 1000? 2,500,000. So it’s probably about 2,500,000.

Or we could approximate a bit more closely: Say 2400 times 1100, that’s about 100 times 100 times 24 times 11, which is 2 times 12 times 11 (times 10,000), which is 2 times (110 plus 22), which is 2 times 132 (times 10,000), which is 2,640,000.

Or, we could actually go through all the steps to do the full multiplication (remember I’m assuming you have no calculator), multiply, carry the 1s, add all four sums, re-check everything and probably fix it because you messed up somewhere; and then eventually you will get: 2,750,403.

So, our really fast method was only off by about 10%. Our moderately-fast method was only off by 4%. And both of them were a lot faster than getting the exact answer by hand.

Which of these methods you’d actually want to use depends on the context and the tools at hand. If you had a calculator, sure, get the exact answer. Even if you didn’t, but you were balancing the budget for a corporation, I’m pretty sure they’d care about that extra $110,403. (Then again, they might not care about the $403 or at least the $3.) But just as an intellectual exercise, you really didn’t need to do anything; the optimal choice may have been to take my word for it. Or, if you were at all curious, you might be better off choosing the quick approximation rather than the precise answer. Since nothing of any real significance hinged on getting that answer, it may be simply a waste of your time to bother finding it.

This is of course a contrived example. But it’s not so far from many choices we make in real life.

Yes, if you are making a big choice—which job to take, what city to move to, whether to get married, which car or house to buy—you should get a precise answer. In fact, I make spreadsheets with formal utility calculations whenever I make a big choice, and I haven’t regretted it yet. (Did I really make a spreadsheet for getting married? You’re damn right I did; there were a lot of big financial decisions to make there—taxes, insurance, the wedding itself! I didn’t decide whom to marry that way, of course; but we always had the option of staying unmarried.)

But most of the choices we make from day to day are small choices: What should I have for lunch today? Should I vacuum the carpet now? What time should I go to bed? In the aggregate they may all add up to important things—but each one of them really won’t matter that much. If you were to construct a formal model to optimize your decision of everything to do each day, you’d spend your whole day doing nothing but constructing formal models. Perfect is bad.

In fact, even for big decisions, you can’t really get a perfect answer. There are just too many unknowns. Sometimes you can spend more effort gathering additional information—but that’s costly too, and sometimes the information you would most want simply isn’t available. (You can look up the weather in a city, visit it, ask people about it—but you can’t really know what it’s like to live there until you do.) Even those spreadsheet models I use to make big decisions contain error bars and robustness checks, and if, even after investing a lot of effort trying to get precise results, I still find two or more choices just can’t be clearly distinguished to within a good margin of error, I go with my gut. And that seems to have been the best choice for me to make. Good enough is perfect.

I think that being gifted as a child trained me to be dangerously perfectionist as an adult. (Many of you may find this familiar.) When it came to solving math problems, or answering quizzes, perfection really was an attainable goal a lot of the time.

As I got older and progressed further in my education, maybe getting every answer right was no longer feasible; but I still could get the best possible grade, and did, in most of my undergraduate classes and all of my graduate classes. To be clear, I’m not trying to brag here; if anything, I’m a little embarrassed. What it mainly shows is that I had learned the wrong priorities. In fact, one of the main reasons why I didn’t get a 4.0 average in undergrad is that I spent a lot more time back then writing novels and nonfiction books, which to this day I still consider my most important accomplishments and grieve that I’ve not (yet?) been able to get them commercially published. I did my best work when I wasn’t trying to be perfect. Good enough is perfect; perfect is bad.

Now here I am on the other side of the academic system, trying to carve out a career, and suddenly, there is no perfection. When my exam is being graded by someone else, there is a way to get the most points. When I’m the one grading the exams, there is no “correct answer” anymore. There is no one scoring me to see if I did the grading the “right way”—and so, no way to be sure I did it right.

Actually, here at Edinburgh, there are other instructors who moderate grades and often require me to revise them, which feels a bit like “getting it wrong”; but it’s really more like we had different ideas of what the grade curve should look like (not to mention US versus UK grading norms). There is no longer an objectively correct answer the way there is for, say, the derivative of x^3, the capital of France, or the definition of comparative advantage. (Or, one question I got wrong on an undergrad exam because I had zoned out of that lecture to write a book on my laptop: Whether cocaine is a dopamine reuptake inhibitor. It is. And the fact that I still remember that because I got it wrong over a decade ago tells you a lot about me.)

And then when it comes to research, it’s even worse: What even constitutes “good” research, let alone “perfect” research? What would be most scientifically rigorous isn’t what journals would be most likely to publish—and without much bigger grants, I can afford neither. I find myself longing for the research paper that will be so spectacular that top journals have to publish it, removing all risk of rejection and failure—in other words, perfect.

Yet such a paper plainly does not exist. Even if I were to do something that would win me a Nobel or a Fields Medal (this is, shall we say, unlikely), it probably wouldn’t be recognized as such immediately—a typical Nobel isn’t awarded until 20 or 30 years after the work that spawned it, and while Fields Medals are faster, they’re by no means instant or guaranteed. In fact, a lot of ground-breaking, paradigm-shifting research was originally relegated to minor journals because the top journals considered it too radical to publish.

Or I could try to do something trendy—feed into DSGE or GTFO—and try to get published that way. But I know my heart wouldn’t be in it, and so I’d be miserable the whole time. In fact, because it is neither my passion nor my expertise, I probably wouldn’t even do as good a job as someone who really buys into the core assumptions. I already have trouble speaking frequentist sometimes: Are we allowed to say “almost significant” for p = 0.06? Maximizing the likelihood is still kosher, right? Just so long as I don’t impose a prior? But speaking DSGE fluently and sincerely? I’d have an easier time speaking in Latin.

What I know—on some level at least—I ought to be doing is finding the research that I think is most worthwhile, given the resources I have available, and then getting it published wherever I can. Or, in fact, I should probably constrain a little by what I know about journals: I should do the most worthwhile research that is feasible for me and has a serious chance of getting published in a peer-reviewed journal. It’s sad that those two things aren’t the same, but they clearly aren’t. This constraint binds, and its Lagrange multiplier is measured in humanity’s future.

But one thing is very clear: By trying to find the perfect paper, I have floundered and, for the last year and a half, not written any papers at all. The right choice would surely have been to write something.

Because good enough is perfect, and perfect is bad.

Apr4 JDN 2459302

Content warning: In this post, I’m going to be talking about violence, including sexual violence. April is Sexual Assault Awareness and Prevention Month. I won’t go into any explicit detail, but I understand that discussion of such topics can still be very upsetting for many people.

After short posts for the past two weeks, get ready for a fairly long post. This is a difficult and complicated topic, and I want to make sure that I state things very clearly and with all necessary nuance.

While the overall level of violence between human societies varies tremendously, one thing is astonishingly consistent: Violence is usually committed by men.

In fact, violence is usually suffered by men as well—with the quite glaring exception of sexual violence. This is why I am particularly offended by claims like “All men benefit from male violence”; no, men who were murdered by other men did not benefit from male violence, and it is frankly appalling to say otherwise. Most men would be better off if male violence were somehow eliminated from the world. (Most women would also be much better off as well, of course.)

I therefore consider it both a matter of both moral obligation and self-interest to endeavor to reduce the amount of male violence in the world, which is almost coextensive with reducing the amount of violence in general.

On the other hand, ought implies can, and despite significant efforts I have made to seek out recommendations for concrete actions I could be taking… I haven’t been able to find very many.

The good news is that we appear to be doing something right—overall rates of violent crime have declined by nearly half since 1990. The decline in rape has been slower, only about 25% since 1990, though this is a bit misleading since the legal definition of rape has been expanded during that interval. The causes of this decline in violence are unclear: Some of the most important factors seem to be changes in policing, economic growth, and reductions in lead pollution. For whatever reason, Millennials just don’t seem to commit crimes at the same rates that Gen-X-ers or Boomers did. We are also substantially more feminist, so maybe that’s an important factor too; the truth is, we really don’t know.

But all of this still leaves me asking: What should I be doing?

When I searched for an answer to this question, a significant fraction of the answers I got from various feminist sources were some variation on “ruminate on your own complicity in male violence”. I tried it; it was painful, difficult—and basically useless. I think this is particularly bad advice for someone like me who has a history of depression.

When you ruminate on your own life, it’s easy to find mistakes; but how important were those mistakes? How harmful were they? I can’t say that I’ve never done anything in my whole life that hurt anyone emotionally (can anyone?), but I can only think of a few times I’ve harmed someone physically (mostly by accident, once in self-defense). I’ve definitely never raped or murdered anyone, and as far as I can tell I’ve never done anything that would have meaningfully contributed to anyone getting raped or murdered. If you were to somehow replace every other man in the world with a copy of me, maybe that wouldn’t immediately bring about a utopian paradise—but I’m pretty sure that rates of violence would be a lot lower. (And in this world ruled by my clones, we’d have more progressive taxes! Less military spending! A basic income! A global democratic federation! Greater investment in space travel! Hey, this sounds pretty good, actually… though inbreeding would be a definite concern.) So, okay, I’m no angel; but I don’t think it’s really fair to say that I’m complicit in something that would radically decrease if everyone behaved as I do.

The really interesting thing is, I think this is true of most men. A typical man commits less than the average amount of violence—because there is great skew in the distribution, with most men committing little or no violence and a small number of men committing lots of violence. Truly staggering amounts of violence are committed by those at the very top of the distribution—that would be mass murderers like Hitler and Stalin. It sounds strange, but if all men in the world were replaced by a typical man, the world would surely be better off. The loss of the very best men would be more than compensated by the removal of the very worst. In fact, since most men are not rapists or murderers, replacing every man in the world with the median man would automatically bring the rates of rape and murder to zero. I know that feminists don’t like to hear #NotAllMen; but it’s not even most men. Maybe the reason that the “not all men” argument keeps coming up is… it’s actually kind of true? Maybe it’s not so unreasonable for men to resent the implication that we are complicit in acts we abhor that we have never done and would never do? Maybe this whole concept that an entire sex of people, literally almost half the human race, can share responsibility for violent crimes—is wrong?

I know that most women face a nearly constant bombardment of sexual harassment, and feel pressured to remain constantly vigilant in order to protect themselves against being raped. I know that victims of sexual violence are often blamed for their victimization (though this happens in a lot of crimes, not just sex crimes). I know that #YesAllWomen is true—basically all women have been in some way harmed or threatened by sexual violence. But the fact remains that most men are already not committing sexual violence. Many people seem to confuse the fact that most women are harmed by men with the claim that most men harm women; these are not at all equivalent. As long as one man can harm many women, there don’t need to be very many harmful men for all women to be affected.

Plausible guesses would be that about 20-25% of women suffer sexual assault, committed by about 4% or 5% of men, each of whom commits an average of 4 to 6 assaults—and some of whom commit far more. If these figures are right, then 95% of men are not guilty of sexual assault. The highest plausible estimate I’ve seen is from a study which found that 11% of men had committed rape. Since it’s only one study and its sample size was pretty small, I’m actually inclined to think that this is an overestimate which got excessive attention because it was so shocking. Larger studies rarely find a number above 5%.

But even if we suppose that it’s really 11%, that leaves 89%; in what sense is 89% not “most men”? I saw some feminist sites responding to this result by saying things like “We can’t imprison 11% of men!” but, uh, we almost do already. About 9% of American men will go to prison in their lifetimes. This is probably higher than it should be—it’s definitely higher than any other country—but if those convictions were all for rape, I’d honestly have trouble seeing the problem. (In fact only about 10% of US prisoners are incarcerated for rape.) If the US were the incarceration capital of the world simply because we investigated and prosecuted rape more reliably, that would be a point of national pride, not shame. In fact, the American conservatives who don’t see the problem with our high incarceration rate probably do think that we’re mostly incarcerating people for things like rape and murder—when in fact large portions of our inmates are incarcerated for drug possession, “public order” crimes, or pretrial detention.

Even if that 11% figure is right, “If you know 10 men, one is probably a rapist” is wrong. The people you know are not a random sample. If you don’t know any men who have been to prison, then you likely don’t know any men who are rapists. 37% of prosecuted rapists have prior criminal convictions, and 60% will be convicted of another crime within 5 years. (Of course, most rapes are never even reported; but where would we get statistics on those rapists?) Rapists are not typical men. They may seem like typical men—it may be hard to tell the difference at a glance, or even after knowing someone for a long time. But the fact that narcissists and psychopaths may hide among us does not mean that all of us are complicit in the crimes of narcissists and psychopaths. If you can’t tell who is a psychopath, you may have no choice but to be wary; but telling every man to search his heart is worthless, because the only ones who will listen are the ones who aren’t psychopaths.

That, I think, is the key disagreement here: Where the standard feminist line is “any man could be a rapist, and every man should search his heart”, I believe the truth is much more like, “monsters hide among us, and we should do everything in our power to stop them”. The monsters may look like us, they may often act like us—but they are not us. Maybe there are some men who would commit rapes but can be persuaded out of it—but this is not at all the typical case. Most rapes are committed by hardened, violent criminals and all we can really do is lock them up. (And for the love of all that is good in the world, test all the rape kits!)

It may be that sexual harassment of various degrees is more spread throughout the male population; perhaps the median man indeed commits some harassment at some point in his life. But even then, I think it’s pretty clear that the really awful kinds of harassment are largely committed by a small fraction of serial offenders. Indeed, there is a strong correlation between propensity toward sexual harassment and various measures of narcissism and psychopathy. So, if most men look closely enough, maybe they can think of a few things that they do occasionally that might make women uncomfortable; okay, stop doing those things. (Hint: Do not send unsolicited dick pics. Ever. Just don’t. Anyone who wants to see your genitals will ask first.) But it isn’t going to make a huge difference in anyone’s life. As long as the serial offenders continue, women will still feel utterly bombarded.

There are other kinds of sexual violations that more men commit—being too aggressive, or persisting too much after the first rejection, or sending unsolicited sexual messages or images. I’ve had people—mostly, but not only, men—do things like that to me; but it would be obviously unfair to both these people and actual rape victims to say I’d ever been raped. I’ve been groped a few times, but it seems like quite a stretch to call it “sexual assault”. I’ve had experiences that were uncomfortable, awkward, frustrating, annoying, occasionally creepy—but never traumatic. Never violence. Teaching men (and women! There is evidence that women are not much less likely than men to commit this sort of non-violent sexual violation) not to do these things is worthwhile and valuable in itself—but it’s not going to do much to prevent rape or murder.

Thus, whatever responsibility men have in reducing sexual violence, it isn’t simply to stop; you can’t stop doing what you already aren’t doing.

After pushing through all that noise, at last I found a feminist site making a more concrete suggestion: They recommended that I read a book by Jackson Katz on the subject entitled The Macho Paradox: Why Some Men Hurt Women and How All Men Can Help.

First of all, I must say I can’t remember any other time I’ve read a book that was so poorly titled. The only mention of the phrase “macho paradox” is a brief preface that was added to the most recent edition explaining what the term was meant to mean; it occurs nowhere else in the book. And in all its nearly 300 pages, the book has almost nothing that seriously addresses either the motivations underlying sexual violence or concrete actions that most men could take in order to reduce it.

As far as concrete actions (“How all men can help”), the clearest, most consistent advice the book seems to offer that would apply to most men is “stop consuming pornography” (something like 90% of men and 60% of women regularly consume porn), when in fact there is a strong negative correlation between consumption of pornography and real-world sexual violence. (Perhaps Millennials are less likely to commit rape and murder because we are so into porn and video games!) This advice is literally worse than nothing.

The sex industry exists on a continuum from the adult-only but otherwise innocuous (smutty drawings and erotic novels), through the legal but often problematic (mainstream porn, stripping), to the usually illegal but defensible (consensual sex work), all the way to the utterly horrific and appalling (the sexual exploitation of children). I am well aware that there are many deep problems with the mainstream porn industry, but I confess I’ve never quite seen how these problems are specific to porn rather than endemic to media or even capitalism more generally. Particularly with regard to the above-board sex industry in places like Nevada or the Netherlands, it’s not obvious to me that a prostitute is more exploited than a coal miner, a sweatshop worker, or a sharecropper—indeed, given the choice between those four careers, I’d without hesitation choose to be a prostitute in Amsterdam. Many sex workers resent the paternalistic insistence by anti-porn feminists that their work is inherently degrading and exploitative. Overall, sex workers report job satisfaction not statistically different than the average for all jobs. There are a multitude of misleading statistics often reported about the sex industry that often make matters seem far worse than they are.

Katz (all-too) vividly describes the depiction of various violent or degrading sex acts in mainstream porn, but he seems unwilling to admit that any other forms of porn do or even could exist—and worse, like far too many anti-porn feminists, he seems to willfully elide vital distinctions, effectively equating fantasy depiction with genuine violence and consensual kinks with sexual abuse. I like to watch action movies and play FPS video games; does that mean I believe it’s okay to shoot people with machine guns? I know the sophisticated claim is that it somehow “desensitizes” us (whatever that means), but there’s not much evidence of that either. Given that porn and video games are negatively correlated with actual violence, it may in fact be that depicting the fantasy provides an outlet for such urges and helps prevent them from becoming reality. Or, it may simply be that keeping a bunch of young men at home in front of their computers keeps them from going out and getting into trouble. (Then again, homicides actually increased during the COVID pandemic—though most other forms of crime decreased.) But whatever the cause, the evidence is clear that porn and video games don’t increase actual violence—they decrease them.

At the very end of the book, Katz hints at a few other things men might be able to do, or at least certain groups of men: Challenge sexism in sports, the military, and similar male-dominated spaces (you know, if you have clout in such spaces, which I really don’t—I’m an effete liberal intellectual, a paradigmatic “soy boy”; do you think football players or soldiers are likely to listen to me?); educate boys with more positive concepts of masculinity (if you are in a position to do so, e.g. as a teacher or parent); or, the very best advice in the entire book, worth more than the rest of the book combined: Donate to charities that support survivors of sexual violence. Katz doesn’t give any specific recommendations, but here are a few for you: RAINN, NAESV and NSVRC.

Honestly, I’m more impressed by Upworthy’s bulleted list of things men can do, though they’re mostly things that conscientious men do anyway, and even if 90% of men did them, it probably wouldn’t greatly reduce actual violence.

As far as motivations (“Why some men hurt women”), the book does at least manage to avoid the mindless slogan “rape is about power, not sex” (there is considerable evidence that this slogan is false or at least greatly overstated). Still, Katz insists upon collective responsibility, attributing what are in fact typically individual crimes, committed mainly by psychopaths, motivated primarily by anger or sexual desire, to some kind of institutionalized system of patriarchal control that somehow permeates all of society. The fact that violence is ubiquitous does not imply that it is coordinated. It’s very much the same cognitive error as “murderism”.

I agree that sexism exists, is harmful, and may contribute to the prevalence of rape. I agree that there are many widespread misconceptions about rape. I also agree that reducing sexism and toxic masculinity are worthwhile endeavors in themselves, with numerous benefits for both women and men. But I’m just not convinced that reducing sexism or toxic masculinity would do very much to reduce the rates of rape or other forms of violence. In fact, despite widely reported success of campaigns like the “Don’t Be That Guy” campaign, the best empirical research on the subject suggests that such campaigns actually tend to do more harm than good. The few programs that seem to work are those that focus on bystander interventions—getting men who are not rapists to recognize rapists and stop them. Basically nothing has ever been shown to convince actual rapists; all we can do is deny them opportunities—and while bystander intervention can do that, the most reliable method is probably incarceration. Trying to change their sexist attitudes may be worse than useless.

Indeed, I am increasingly convinced that much—not all, but much—of what is called “sexism” is actually toxic expressions of heterosexuality. Why do most creepy male bosses only ever hit on their female secretaries? Well, maybe because they’re straight? This is not hard to explain. It’s a fair question why there are so many creepy male bosses, but one need not posit any particular misogyny to explain why their targets would usually be women. I guess it’s a bit hard to disentangle; if an incel hates women because he perceives them as univocally refusing to sleep with him, is that sexism? What if he’s a gay incel (yes they exist) and this drives him to hate men instead?

In fact, I happen to know of a particular gay boss who has quite a few rumors surrounding him regarding his sexual harassment of male employees. Or you could look at Kevin Spacey, who (allegedly) sexually abused teenage boys. You could tell a complicated story about how this is some kind of projection of misogynistic attitudes onto other men (perhaps for being too “femme” or something)—or you could tell a really simple story about how this man is only sexually abusive toward other men because that’s the gender of people he’s sexually attracted to. Occam’s Razor strongly favors the latter.

Indeed, what are we to make of the occasional sexual harasser who targets men and women equally? On the theory that abuse is caused by patriarchy, that seems pretty hard to explain. On the theory that abusive people sometimes happen to be bisexual, it’s not much of a mystery. (Though I would like to take a moment to debunk the stereotype of the “depraved bisexual”: Bisexuals are no more likely to commit sexual violence, but are far more likely to suffer it—more likely than either straight or gay people, independently of gender. Trans people face even higher risk; the acronym LGBT is in increasing order of danger of violence.)

Does this excuse such behavior? Absolutely not. Sexual harassment and sexual assault are definitely wrong, definitely harmful, and rightfully illegal. But when trying to explain why the victims are overwhelmingly female, the fact that roughly 90% of people are heterosexual is surely relevant. The key explanandum here is not why the victims are usually female, but rather why the perpetrators are usually male.

That, indeed, requires explanation; but such an explanation is really not so hard to come by. Why is it that, in nearly every human society, for nearly every form of violence, the vast majority of that violence is committed by men? It sure looks genetic to me.

Indeed, in anyother context aside from gender or race, we would almost certainly reject any explanation other than genetics for such a consistent pattern. Why is it that, in nearly every human society, about 10% of people are LGBT? Probably genetics. Why is it that, in near every human society, about 10% of people are left-handed? Genetics. Why, in nearly every human society, do smiles indicate happiness, children fear loud noises, and adults fear snakes? Genetics. Why, in nearly every human society, are men on average much taller and stronger than women? Genetics. Why, in nearly every human society, is about 90% of violence, including sexual violence, committed by men? Clearly, it’s patriarchy.

A massive body of scientific evidence from multiple sources shows a clear casual relationship between increased testosterone and increased aggression. The correlation is moderate, only about 0.38—but it’s definitely real. And men have a lot more testosterone than women: While testosterone varies a frankly astonishing amount between men and over time—including up to a 2-fold difference even over the same day—a typical adult man has about 250 to 950 ng/dL of blood testosterone, while a typical adult woman has only 8 to 60 ng/dL. (An adolescent boy can have as much as 1200 ng/dL!) This is a difference ranging from a minimum of 4-fold to a maximum of over 100-fold, with a typical value of about 20-fold. It would be astonishing if that didn’t have some effect on behavior.

This is of course far from a complete explanation: With a correlation of 0.38, we’ve only explained about 14% of the variance, so what’s the other 86%? Well, first of all, testosterone isn’t the only biological difference between men and women. It’s difficult to identify any particular genes with strong effects on aggression—but the same is true of height, and nobody disputes that the height difference between men and women is genetic.

Clearly societal factors do matter a great deal, or we couldn’t possibly explain why homicide rates vary between countries from less than 3 per million per year in Japan to nearly 400 per million per year in Honduras—a full 2 orders of magnitude! But gender inequality does not appear to strongly predict homicide rates. Japan is not a very feminist place (in fact, surveys suggest that, after Spain, Japan is second-worst highly-developed country for women). Sweden is quite feminist, and their homicide rate is relatively low; but it’s still 4 times as high as Japan’s. The US doesn’t strike me as much more sexist than Canada (admittedly subjective—surveys do suggest at least some difference, and in the expected direction), and yet our homicide rate is nearly 3 times as high. Also, I think it’s worth noting that while overall homicide rates vary enormously across societies, the fact that roughly 90% of homicides are committed by men does not. Through some combination of culture and policy, societies can greatly reduce the overall level of violence—but no society has yet managed to change the fact that men are more violent than women.

I would like to do a similar analysis of sexual assault rates across countries, but unfortunately I really can’t, because different countries have such different laws and different rates of reporting that the figures really aren’t comparable. Sweden infamously has a very high rate of reported sex crimes, but this is largely because they have very broad definitions of sex crimes and very high rates of reporting. The best I can really say for now is there is no obvious pattern of more feminist countries having lower rates of sex crimes. Maybe there really is such a pattern; but the data isn’t clear.

Yet if biology contributes anything to the causation of violence—and at this point I think the evidence for that is utterly overwhelming—then mainstream feminism has done the world a grave disservice by insisting upon only social and cultural causes. Maybe it’s the case that our best options for intervention are social or cultural, but that doesn’t mean we can simply ignore biology. And then again, maybe it’s not the case at all:A neurological treatment to cure psychopathy could cut almost all forms of violence in half.

I want to be completely clear that a biological cause is not a justification or an excuse: literally billions of men manage to have high testosterone levels, and experience plenty of anger and sexual desire, without ever raping or murdering anyone. The fact that men appear to be innately predisposed toward violence does not excuse actual violence, and the fact that rape is typically motivated at least in part by sexual desire is no excuse for committing rape.

In fact, I’m quite worried about the opposite: that the notion that sexual violence is always motivated by a desire to oppress and subjugate women will be used to excuse rape, because men who know that their motivation was not oppression will therefore be convinced that what they did wasn’t rape. If rape is always motivated by a desire to oppress women, and his desire was only to get laid, then clearly, what he did can’t be rape, right? The logic here actually makes sense. If we are to reject this argument—as we must—then we must reject the first premise, that all rape is motivated by a desire to oppress and subjugate women. I’m not saying that’s never a motivation—I’m simply saying we can’t assume it is always.

The truth is, I don’t know how to end violence, and sexual violence may be the most difficult form of violence to eliminate. I’m not even sure what most of us can do to make any difference at all. For now, the best thing to do is probably to donate money to organizations like RAINN, NAESV and NSVRC. Even $10 to one of these organizations will do more to help survivors of sexual violence than hours of ruminating on your own complicity—and cost you a lot less.

Signaling and the Curse of Knowledge

Jan 3 JDN 2459218

I received several books for Christmas this year, and the one I was most excited to read first was The Sense of Style by Steven Pinker. Pinker is exactly the right person to write such a book: He is both a brilliant linguist and cognitive scientist and also an eloquent and highly successful writer. There are two other books on writing that I rate at the same tier: On Writing by Stephen King, and The Art of Fiction by John Gardner. Don’t bother with style manuals from people who only write style manuals; if you want to learn how to write, learn from people who are actually successful at writing.

Indeed, I knew I’d love The Sense of Style as soon as I read its preface, containing some truly hilarious takedowns of Strunk & White. And honestly Strunk & White are among the best standard style manuals; they at least actually manage to offer some useful advice while also being stuffy, pedantic, and often outright inaccurate. Most style manuals only do the second part.

One of Pinker’s central focuses in The Sense of Style is on The Curse of Knowledge, an all-too-common bias in which knowing things makes us unable to appreciate the fact that other people don’t already know it. I think I succumbed to this failing most greatly in my first book, Special Relativity from the Ground Up, in which my concept of “the ground” was above most people’s ceilings. I was trying to write for high school physics students, and I think the book ended up mostly being read by college physics professors.

The problem is surely a real one: After years of gaining expertise in a subject, we are all liable to forget the difficulty of reaching our current summit and automatically deploy concepts and jargon that only a small group of experts actually understand. But I think Pinker underestimates the difficulty of escaping this problem, because it’s not just a cognitive bias that we all suffer from time to time. It’s also something that our society strongly incentivizes.

Pinker points out that a small but nontrivial proportion of published academic papers are genuinely well written, using this to argue that obscurantist jargon-laden writing isn’t necessary for publication; but he didn’t seem to even consider the fact that nearly all of those well-written papers were published by authors who already had tenure or even distinction in the field. I challenge you to find a single paper written by a lowly grad student that could actually get published without being full of needlessly technical terminology and awkward passive constructions: “A murian model was utilized for the experiment, in an acoustically sealed environment” rather than “I tested using mice and rats in a quiet room”. This is not because grad students are more thoroughly entrenched in the jargon than tenured professors (quite the contrary), nor that grad students are worse writers in general (that one could really go either way), but because grad students have more to prove. We need to signal our membership in the tribe, whereas once you’ve got tenure—or especially once you’ve got an endowed chair or something—you have already proven yourself.

Pinker seems to briefly touch this insight (p. 69), without fully appreciating its significance: “Even when we have an inlkling that we are speaking in a specialized lingo, we may be reluctant to slip back into plain speech. It could betray to our peers the awful truth that we are still greenhorns, tenderfoots, newbies. And if our readers do know the lingo, we might be insulting their intelligence while spelling it out. We would rather run the risk of confusing them while at least appearing to be soophisticated than take a chance at belaboring the obvious while striking them as naive or condescending.”

What we are dealing with here is a signaling problem. The fact that one can write better once one is well-established is the phenomenon of countersignaling, where one who has already established their status stops investing in signaling.

Here’s a simple model for you. Suppose each person has a level of knowledge x, which they are trying to demonstrate. They know their own level of knowledge, but nobody else does.

Suppose that when we observe someone’s knowledge, we get two pieces of information: We have an imperfect observation of their true knowledge which is x+e, the real value of x plus some amount of error e. Nobody knows exactly what the error is. To keep the model as simple as possible I’ll assume that e is drawn from a uniform distribution between -1 and 1.

Finally, assume that we are trying to select people above a certain threshold: Perhaps we are publishing in a journal, or hiring candidates for a job. Let’s call that threshold z. If x < z-1, then since e can never be larger than 1, we will immediately observe that they are below the threshold and reject them. If x > z+1, then since e can never be smaller than -1, we will immediately observe that they are above the threshold and accept them.

But when z-1 < x < z+1, we may think they are above the threshold when they actually are not (if e is positive), or think they are not above the threshold when they actually are (if e is negative).

So then let’s say that they can invest in signaling by putting some amount of visible work in y (like citing obscure papers or using complex jargon). This additional work may be costly and provide no real value in itself, but it can still be useful so long as one simple condition is met: It’s easier to do if your true knowledge x is high.

In fact, for this very simple model, let’s say that you are strictly limited by the constraint that y <= x. You can’t show off what you don’t know.

If your true value x > z, then you should choose y = x. Then, upon observing your signal, we know immediately that you must be above the threshold.

But if your true value x < z, then you should choose y = 0, because there’s no point in signaling that you were almost at the threshold. You’ll still get rejected.

Yet remember before that only those with z-1 < x < z+1 actually need to bother signaling at all. Those with x > z+1 can actually countersignal, by also choosing y = 0. Since you already have tenure, nobody doubts that you belong in the club.

This means we’ll end up with three groups: Those with x < z, who don’t signal and don’t get accepted; those with z < x < z+1, who signal and get accepted; and those with x > z+1, who don’t signal but get accepted. Then life will be hardest for those who are just above the threshold, who have to spend enormous effort signaling in order to get accepted—and that sure does sound like grad school.

You can make the model more sophisticated if you like: Perhaps the error isn’t uniformly distributed, but some other distribution with wider support (like a normal distribution, or a logistic distribution); perhaps the signalling isn’t perfect, but itself has some error; and so on. With such additions, you can get a result where the least-qualified still signal a little bit so they get some chance, and the most-qualified still signal a little bit to avoid a small risk of being rejected. But it’s a fairly general phenomenon that those closest to the threshold will be the ones who have to spend the most effort in signaling.

This reveals a disturbing overlap between the Curse of Knowledge and Impostor Syndrome: We write in impenetrable obfuscationist jargon because we are trying to conceal our own insecurity about our knowledge and our status in the profession. We’d rather you not know what we’re talking about than have you realize that we don’t know what we’re talking about.

For the truth is, we don’t know what we’re talking about. And neither do you, and neither does anyone else. This is the agonizing truth of research that nearly everyone doing research knows, but one must be either very brave, very foolish, or very well-established to admit out loud: It is in the nature of doing research on the frontier of human knowledge that there is always far more that we don’t understand about our subject than that we do understand.

I would like to be more open about that. I would like to write papers saying things like “I have no idea why it turned out this way; it doesn’t make sense to me; I can’t explain it.” But to say that the profession disincentivizes speaking this way would be a grave understatement. It’s more accurate to say that the profession punishes speaking this way to the full extent of its power. You’re supposed to have a theory, and it’s supposed to work. If it doesn’t actually work, well, maybe you can massage the numbers until it seems to, or maybe you can retroactively change the theory into something that does work. Or maybe you can just not publish that paper and write a different one.

Here is a graph of one million published z-scores in academic journals:

It looks like a bell curve, except that almost all the values between -2 and 2 are mysteriously missing.

If we were actually publishing all the good science that gets done, it would in fact be a very nice bell curve. All those missing values are papers that never got published, or results that were excluded from papers, or statistical analyses that were massaged, in order to get a p-value less than the magical threshold for publication of 0.05. (For the statistically uninitiated, a z-score less than -2 or greater than +2 generally corresponds to a p-value less than 0.05, so these are effectively the same constraint.)

I have literally never read a single paper published in an academic journal in the last 50 years that said in plain language, “I have no idea what’s going on here.” And yet I have read many papers—probably most of them, in fact—where that would have been an appropriate thing to say. It’s actually quite a rare paper, at least in the social sciences, that actually has a theory good enough to really precisely fit the data and not require any special pleading or retroactive changes. (Often the bar for a theory’s success is lowered to “the effect is usually in the right direction”.) Typically results from behavioral experiments are bizarre and baffling, because people are a little screwy. It’s just that nobody is willing to stake their career on being that honest about the depth of our ignorance.

This is a deep shame, for the greatest advances in human knowledge have almost always come from people recognizing the depth of their ignorance. Paradigms never shift until people recognize that the one they are using is defective.

This is why it’s so hard to beat the Curse of Knowledge: You need to signal that you know what you’re talking about, and the truth is you probably don’t, because nobody does. So you need to sound like you know what you’re talking about in order to get people to listen to you. You may be doing nothing more than educated guesses based on extremely limited data, but that’s actually the best anyone can do; those other people saying they have it all figured out are either doing the same thing, or they’re doing something even less reliable than that. So you’d better sound like you have it all figured out, and that’s a lot more convincing when you “utilize a murian model” than when you “use rats and mice”.

Perhaps we can at least push a little bit toward plainer language. It helps to be addressing a broader audience: it is both blessing and curse that whatever I put on this blog is what you will read, without any gatekeepers in my path. I can use plainer language here if I so choose, because no one can stop me. But of course there’s a signaling risk here as well: The Internet is a public place, and potential employers can read this as well, and perhaps decide they don’t like me speaking so plainly about the deep flaws in the academic system. Maybe I’d be better off keeping my mouth shut, at least for awhile. I’ve never been very good at keeping my mouth shut.

Once we get established in the system, perhaps we can switch to countersignaling, though even this doesn’t always happen. I think there are two reasons this can fail: First, you can almost always try to climb higher. Once you have tenure, aim for an endowed chair. Once you have that, try to win a Nobel. Second, once you’ve spent years of your life learning to write in a particular stilted, obscurantist, jargon-ridden way, it can be very difficult to change that habit. People have been rewarding you all your life for writing in ways that make your work unreadable; why would you want to take the risk of suddenly making it readable?

I don’t have a simple solution to this problem, because it is so deeply embedded. It’s not something that one person or even a small number of people can really fix. Ultimately we will need to, as a society, start actually rewarding people for speaking plainly about what they don’t know. Admitting that you have no clue will need to be seen as a sign of wisdom and honesty rather than a sign of foolishness and ignorance. And perhaps even that won’t be enough: Because the fact will still remain that knowing what you know that other people don’t know is a very difficult thing to do.

What meritocracy trap?

Nov 1 JDN 2459155

So I just finished reading The Meritocracy Trap by David Markovits.

The basic thesis of the book is that America’s rising inequality is not due to a defect in our meritocratic ideals, but is in fact their ultimate fruition. Markovits implores us to reject the very concept of meritocracy, and replace it with… well, something, and he’s never very clear about exactly what.

The most frustrating thing about reading this book is trying to figure out where Markovits draws the line for “elite”. He rapidly jumps between talking about the upper quartile, the upper decile, the top 1%, and even the top 0.1% or top 0.01% while weaving his narrative. The upper quartile of the US contains 75 million people; the top 0.01% contains only 300,000. The former is the size of Germany, the latter the size of Iceland (which has fewer people than Long Beach). Inequality which concentrates wealth in the top quartile of Americans is a much less serious problem than inequality which concentrates wealth in the top 0.01%. It could still be a problem—those lower three quartiles are people too—but it is definitely not nearly as bad.

I think it’s particularly frustrating to me personally, because I am an economist, which means both that such quantitative distinctions are important to me, and also that whether or not I myself am in this “elite” depends upon which line you are drawing. Do I have a post-graduate education? Yes. Was I born into the upper quartile? Not quite, but nearly. Was I raised by married parents in a stable home? Certainly. Am I in the upper decile and working as a high-paid professional? Hopefully I will be soon. Will I enter the top 1%? Maybe, maybe not. Will I join the top 0.1%? Probably not. Will I ever be in the top 0.01% and a captain of industry? Almost certainly not.

So, am I one of the middle class who are suffering alienation and stagnation, or one of the elite who are devouring themselves with cutthroat competition? Based on BLS statistics for economists and job offers I’ve been applying to, my long-term household income is likely to be about 20-50% higher than my parents’; this seems like neither the painful stagnation he attributes to the middle class nor the unsustainable skyrocketing of elite incomes. (Even 50% in 30 years is only 1.4% per year, about our average rate of real GDP growth.) Marxists would no doubt call me petit bourgeoisie; but isn’t that sort of the goal? We want as many people as possible to live comfortable upper-middle class lives in white-collar careers?

Markovits characterizes—dare I say caricatures—the habits of the middle-class versus the elite, and once again I and most people I know cross-cut them: I spend more time with friends than family (elite), but I cook familiar foods, not fancy dinners (middle); I exercise fairly regularly and don’t watch much television (elite) but play a lot of video games and sleep a lot as well (middle). My web searches involve technology and travel (elite), but also chronic illness (middle). I am a donor to Amnesty International (elite) but also play tabletop role-playing games (middle). I have a functional, inexpensive car (middle) but a top-of-the-line computer (elite)—then again that computer is a few years old now (middle). Most of the people I hang out with are well-educated (elite) but struggling financially (middle), civically engaged (elite) but pessimistic (middle). I rent my apartment and have a lot of student debt (middle) but own stocks (elite). (The latter seemed like a risky decision before the pandemic, but as stock prices have risen and student loan interest was put on moratorium, it now seems positively prescient.) So which class am I, again?

I went to public school (middle) but have a graduate degree (elite). I grew up in Ann Arbor (middle) but moved to Irvine (elite). Then again my bachelor’s was at a top-10 institution (elite) but my PhD will be at only a top-50 (middle). The beautiful irony there is that the top-10 institution is the University of Michigan and the top-50 institution is the University of California, Irvine. So I can’t even tell which class each of those events is supposed to represent! Did my experience of Ann Arbor suddenly shift from middle class to elite when I graduated from public school and started attending the University of Michigan—even though about a third of my high school cohort did exactly that? Was coming to UCI an elite act because it’s a PhD in Orange County, or a middle-class act because it’s only a top-50 university?

If the gap between these two classes is such a wide chasm, how am I straddling it? I honestly feel quite confident in characterizing myself as precisely the upwardly-mobile upper-middle class that Markovits claims no longer exists. Perhaps we’re rarer than we used to be; perhaps our status is more precarious; but we plainly aren’t gone.

Markovits keeps talking about “radical differences” “not merely in degree but in kind” between “subordinate” middle-class workers and “superordinate” elite workers, but if the differences are really that stark, why is it so hard to tell which group I’m in? From what I can see, the truth seems less like a sharp divide between middle-class and upper-class, and more like an increasingly steep slope from middle-class to upper-middle class to upper-class to rich to truly super-rich. If I had to put numbers on this, I’d say annual household incomes of about $50,000, $100,000, $200,000, $400,000, $1 million, and $10 million respectively. (And yet perhaps I should add more categories: Even someone who makes $10 million a year has only pocket change next to Elon Musk or Jeff Bezos.) The slope has gotten steeper over time, but it hasn’t (yet?) turned into a sharp cliff the way Markovits describes. America’s Lorenz curve is clearly too steep, but it doesn’t have a discontinuity as far as I can tell.

Some of the inequalities Markovits discusses are genuine, but don’t seem to be particularly related to meritocracy. The fact that students from richer families go to better schools indeed seems unjust, but the problem is clearly not that the rich schools are too good (except maybe at the very top, where truly elite schools seem a bit excessive—five-figure preschool tuition?), but that the poor schools are not good enough. So it absolutely makes sense to increase funding for poor schools and implement various reforms, but this is hardly a radical notion—nor is it in any way anti-meritocratic. Providing more equal opportunities for the poor to raise their own station is what meritocracy is all about.

Other inequalities he objects to seem, if not inevitable, far too costly to remove: Educated people are better parents, who raise their children in ways that make them healthier, happier, and smarter? No one is going to apologize for being a good parent, much less stop doing so because you’re concerned about what it does to inequality. If you have some ideas for how we might make other people into better parents, by all means let’s hear them. But I believe I speak for the entire upper-middle class when I say: when I have kids of my own, I’m going to read to them, I’m not going to spank them, and there’s not a damn thing you can do to change my mind on either front. Quite frankly, this seems like a heavy-handed satire of egalitarianism, right out of Harrison Bergeron: Let’s make society equal by forcing rich people to neglect and abuse their kids as much as poor people do! My apologies to Vonnegut: I thought you were ridiculously exaggerating, but apparently some people actually think like this.

This is closely tied with the deepest flaw in the argument: The meritocratic elite are actually more qualified. It’s easy to argue that someone like Donald Trump shouldn’t rule the world; he’s a deceitful, narcissistic, psychopathic, incompetent buffoon. (The only baffling part is that 40% of American voters apparently disagree.) But it’s a lot harder to see why someone like Bill Gates shouldn’t be in charge of things: He’s actually an extremely intelligent, dedicated, conscientious, hard-working, ethical, and competent individual. Does he deserve $100 billion? No, for reasons I’ve talked about before. But even he knows that! He’s giving most of it away to highly cost-effective charities! Bill Gates alone has saved several million lives by his philanthropy.

Markovits tries to argue that the merits of the meritocratic elite are arbitrary and contextual, like the alleged virtues of the aristocratic class: “The meritocratic virtues, that is, are artifacts of economic inequality in just the fashion in which the pitching virtues are artifacts of baseball.” (p. 264) “The meritocratic achievement commonly celebrated today, no less than the aristocratic virtue acclaimed in the ancien regime, is a sham.” (p. 268)

But it’s pretty hard for me to see how things like literacy, knowledge of history and science, and mathematical skill are purely arbitrary. Even the highly specialized skills of a quantum physicist, software engineer, or geneticist are clearly not arbitrary. Not everyone needs to know how to solve the Schrodinger equation or how to run a polymerase chain reaction, but our civilization greatly benefits from the fact that someone does. Software engineers aren’t super-productive because of high inequality; they are super-productive because they speak the secret language of the thinking machines. I suppose some of the skills involved in finance, consulting, and law are arbitrary and contextual; but he makes it sound like the only purpose graduate school serves is in teaching us table manners.

Precisely by attacking meritocracy, Markovits renders his own position absurd. So you want less competent people in charge? You want people assigned to jobs they’re not good at? You think businesses should go out of their way to hire employees who will do their jobs worse? Had he instead set out to show how American society fails at achieving its meritocratic ideals—indeed, failing to provide equality of opportunity for the poor is probably the clearest example of this—he might have succeeded. But instead he tries to attack the ideals themselves, and fails miserably.

Markovits avoids the error that David Graeber made: Graeber sees that there are many useless jobs but doesn’t seem to have a clue why these jobs exist (and turns to quite foolish Marxian conspiracy theories to explain it). Markovits understands that these jobs are profitable for the firms that employ them, but unproductive for society as a whole. He is right; this is precisely what virtually the entire fields of finance, sales, advertising, and corporate law consist of. Most people in our elite work very hard with great skill and competence, and produce great profits for the corporations that employ them, all while producing very little of genuine societal value. But I don’t see how this is a flaw in meritocracy per se.

Nor does Markovits stop at accusing employment of being rent-seeking; he takes aim at education as well: “when the rich make exceptional investments in schooling, this does reduce the value of ordinary, middle-class training and degrees. […] Meritocratic education inexorably engenders a wasteful and destructive arms educational arms race, which ultimately benefits no one, not even the victors.” (p.153) I don’t doubt that education is in part such a rent-seeking arms race, and it’s worthwhile to try to minimize that. But education is not entirely rent-seeking! At the very least, is there not genuine value in teaching children to read and write and do arithmetic? Perhaps by the time we get to calculus or quantum physics or psychopathology we have reached diminishing returns for most students (though clearly at least some people get genuine value out of such things!), but education is not entirely comprised of signaling or rent-seeking (and nor do “sheepskin effects” prove otherwise).

My PhD may be less valuable to me than it would be to someone in my place 40 years ago, simply because there are more people with PhDs now and thus I face steeper competition. Then again, perhaps not, as the wage premium for college and postgraduate education has been increasing, not decreasing, over that time period. (How much of that wage premium is genuine social benefit and how much is rent-seeking is difficult to say.) In any case it’s definitely still valuable. I have acquired many genuine skills, and will in fact be able to be genuinely more productive as well as compete better in the labor market than I would have without it. Some parts of it have felt like a game where I’m just trying to stay ahead of everyone else, but it hasn’t all been that. A world where nobody had PhDs would be a world with far fewer good scientists and far slower technological advancement.

Abandoning meritocracy entirely would mean that we no longer train people to be more productive or match people to the jobs they are most qualified to do. Do you want a world where surgery is not done by the best surgeons, where airplanes are not flown by the best pilots? This necessarily means less efficient production and an overall lower level of prosperity for society as a whole. The most efficient way may not be the best way, but it’s still worth noting that it’s the most efficient way.

Really, is meritocracy the problem, or is it something else?

Markovits is clearly right that something is going wrong with American society: Our inequality is much too high, and our job market is much too cutthroat. I can’t even relate to his description of what the job market was like in the 1960s (“Old Economy Steve” has it right): “Even applicants for white-collar jobs received startlingly little scrutiny. For most midcentury workers, getting a job did not involve any application at all, in the competitive sense of the term.” (p.203)

In fact, if anything he seems to understate the difference across time, perhaps because it lets him overstate the difference across class (p. 203):

Today, by contrast, the workplace is methodically arranged around gradations of skill. Firms screen job candidates intensively at hiring, and they then sort elite and non-elite workers into separate physical spaces.

Only the very lowest-wage employers, seeking unskilled workers, hire casually. Middle-class employers screen using formal cognitive tests and lengthy interviews. And elite employers screen with urgent intensity, recruiting from only a select pool and spending millions of dollars to probe applicants over several rounds of interviews, lasting entire days.

Today, not even the lowest-wage employers hire casually! Have you ever applied to work at Target? There is a personality test you have to complete, which I presume is designed to test your reliability as an obedient corporate drone. Never in my life have I gotten a job that didn’t involve either a lengthy application process or some form of personal connection—and I hate to admit it, but usually the latter. It is literally now harder to get a job as a cashier at Target than it was to get a job as an engineer at Ford 60 years ago.

But I still can’t shake the feeling that meritocracy is not exactly what’s wrong here. The problem with the sky-high compensation packages at top financial firms isn’t that they are paid to people who are really good at their jobs; it’s that those jobs don’t actually accomplish anything beneficial for society. Where elite talent and even elite compensation is combined with genuine productivity, such as in science and engineering, it seems unproblematic (and I note that Markovits barely even touches on these industries, perhaps because he sees they would undermine his argument). The reason our economic growth seems to have slowed as our inequality has massively surged isn’t that we are doing too good a job of rewarding people for being productive.

Indeed, it seems like the problem may be much simpler: Labor supply exceeds labor demand.

Take a look at this graph from the Federal Reserve Bank of San Francisco:

[Beveridge_curve_data.png]

This graph shows the relationship over time between unemployment and job vacancies. As you can see, they are generally inversely related: More vacancies means less unemployment. I have drawn in a green line which indicates the cutoff between having more vacancies than unemployment—upper left—and having more unemployment than vacancies—lower right. We have almost always been in the state of having more unemployment than we have vacancies; notably, the mid-1960s were one of the few periods in which we had significantly more vacancies than unemployment.

For decades we’ve been instituting policies to try to give people “incentives to work”; but there is no shortage of labor in this country. We seem to have plenty of incentives to work—what we need are incentives to hire people and pay them well.

Indeed, perhaps we need incentives not to work—like a basic income or an expanded social welfare system. Thanks to automation, productivity is now astonishingly high, and yet we work ourselves to death instead of enjoying leisure.

And of course there are various other policy changes that have made our inequality worse—chiefly the dramatic drops in income tax rates at the top brackets that occurred under Reagan.

In fact, many of the specific suggestions Markovits makes—which, much to my chagrin, he waits nearly 300 pages to even mention—are quite reasonable, or even banal: He wants to end tax deductions for alumni donations to universities and require universities to enroll more people from lower income brackets; I could support that. He wants to regulate finance more stringently, eliminate most kinds of complex derivatives, harmonize capital gains tax rates to ordinary income rates, and remove the arbitrary cap on payroll taxes; I’ve been arguing for all of those things for years. What about any of these policies is anti-meritocratic? I don’t see it.

More controversially, he wants to try to re-organize production to provide more opportunities for mid-skill labor. In some industries I’m not sure that’s possible: The 10X programmer is a real phenomenon, and even mediocre programmers and engineers can make software and machines that are a hundred times as productive as doing the work by hand would be. But some of his suggestions make sense, such as policies favoring nurse practitioners over specialist doctors and legal secretaries instead of bar-certified lawyers. (And please, please reform the medical residency system! People die from the overwork caused by our medical residency system.)

But I really don’t see how not educating people or assigning people to jobs they aren’t good at would help matters—which means that meritocracy, as I understand the concept, is not to blame after all.

Forget the Doughnut. Meet the Wedge.

Mar 11 JDN 2458189

I just finished reading Kate Raworth’s book Doughnut Economics: Seven Ways to Think Like a 21st-Century Economist; Raworth also has a whole website dedicated to the concept of the Doughnut as a way of rethinking economics.

The book is very easy to read, and manages to be open to a wide audience with only basic economics knowledge without feeling patronizing or condescending. Most of the core ideas are fundamentally sound, though Raworth has a way of making it sound like she is being revolutionary even when most mainstream economists already agree with the core ideas.

For example, she makes it sound like it is some sort of dogma among neoclassical economists that GDP growth must continue at the same pace forever. As I discussed in an earlier post, the idea that growth will slow down is not radical in economics—it is basically taken for granted in the standard neoclassical growth models.

Even the core concept of the Doughnut isn’t all that radical. It’s based on the recognition that economic development is necessary to end poverty, but resources are not unlimited. Then combine that with two key assumptions: GDP growth requires growth in energy consumption, and growth in energy consumption requires increased carbon emissions. Then, the goal should be to stay within a certain range: We want to be high enough to not have poverty, but low enough to not exceed our carbon budget.

Why a doughnut? That’s… actually a really good question. The concept Raworth presents is a fundamentally one-dimensional object; there’s no reason for it to be doughnut-shaped. She could just as well have drawn it on a single continuum, with poverty at one end, unsustainability at the other end, and a sweet spot in the middle. The doughnut shape adds some visual appeal, but no real information.

But the fundamental assumptions that GDP requires energy and energy requires carbon emissions are simply false—especially the second one. Always keep one thing in mind whenever you’re reading something by environmentalists telling you we need to reduce economic output to save the Earth: Nuclear power does not produce carbon emissions.

This is how the environmentalist movement has shot itself—and the world—in the foot for the last 50 years. They continually refuse to admit that nuclear power is the best hope we have for achieving both economic development and ecological sustainability. They have let their political biases cloud their judgment on what is actually best for humanity’s future.

I will give Raworth some credit for not buying into the pipe dream that we can somehow transition rapidly to an entirely solar and wind-based power grid—renewables only produce 6% of world energy (the most they ever have), while nuclear produces 10%. And nuclear power certainly has its downsides, particularly in its high cost of construction. It may in fact be the case that we need to reduce economic output somewhat, particularly in the very richest countries, and if so, we need to find a way to do that without causing social and political collapse.

The Dougnut is a one-dimensional object glorified by a two-dimensional diagram.

So let me present you with an actual two-dimensional object, which I call the Wedge.

On this graph, the orange dots plot actual GDP per capita (at purchasing power parity) on the X axis against actual CO2 emissions per capita on the Y-axis. The green horizonal line is a CO2 emission target of 3 tonnes per person per year based on reports from the International Panel on Climate Change.

Wedge_full

As you can see, most countries are above the green line. That’s bad. We need the whole world below that green line. The countries that are below the line are largely poor countries, with a handful of middle-income countries mixed in.

But it’s the blue diagonal line that really makes this graph significant, what makes it the Wedge. That line uses Switzerland’s level of efficiency to estimate a frontier of what’s possible. Switzerland’s ratio of GDP to CO2 is the best in the world, among countries where the data actually looks reliable. A handful of other countries do better in the data, but for some (Macau) it’s obviously due to poor counting of indirect emissions and for others (Rwanda, Chad, Burundi) we just don’t have good data at all. I think Switzerland’s efficiency level of $12,000 per ton of CO2 is about as good as can be reasonably expected for most countries over the long run.

Our goal should be to move as far right on the graph as we can (toward higher levels of economic development), but always staying inside this Wedge: Above the green line, our CO2 emissions are too high. Below the blue line may not be technologically feasible (though of course it’s worth a try). We want to aim for the point of the wedge, where GDP is as high as possible but emissions are still below safe targets.

Zooming in on the graph gives a better view of the Wedge.

Wedge_zoomed

The point of the Wedge is about $38,000 per person per year. This is not as rich as the US, but it’s definitely within the range of highly-developed countries. This is about the same standard of living as Italy, Spain, or South Korea. In fact, all three of these countries exceed their targets; the closest I was able to find to a country actually hitting the point of the wedge was Latvia, at $27,300 and 3.5 tonnes per person per year. Uruguay also does quite well at $22,400 and 2.2 tonnes per person per year.

Some countries are within the Wedge; a few, like Uruguay, quite close to the point, and many, like Colombia and Bangladesh, that are below and to the left. For these countries, a “stay the course” policy is the way to go: If they keep up what they are doing, they can continue to experience economic growth without exceeding their emission targets.

 

But the most important thing about the graph is not actually the Wedge itself: It’s all the countries outside the Wedge, and where they are outside the Wedge.

There are some countries, like Sweden, France, and Switzerland, that are close to the blue line but still outside the Wedge because they are too far to the right. These are countries for whom “degrowth” policies might actually make sense: They are being as efficient in their use of resources as may be technologically feasible, but are simply producing too much output. They need to find a way to scale back their economies without causing social and political collapse. My suggestion, for what it’s worth, is progressive taxation. In addition to carbon taxes (which are a no-brainer), make income taxes so high that they start actually reducing GDP, and do so without fear, since that’s part of the point; then redistribute all the income as evenly as possible so that lower total income comes with much lower inequality and the eradication of poverty. Most of the country will then be no worse off than they were, so social and political unrest seems unlikely. Call it “socialism” if you like, but I’m not suggesting collectivization of industry or the uprising of the proletariat; I just want everyone to adopt the income tax rates the US had in the 1950s.

But most countries are not even close to the blue line; they are well above it. In all these countries, the goal should not be to reduce economic output, but to increase the carbon efficiency of that output. Increased efficiency has no downside (other than the transition cost to implement it): It makes you better off ecologically without making you worse off economically. Bahrain has about the same GDP per capita as Sweden but produces over five times the per-capita carbon emissions. Simply by copying Sweden they could reduce their emissions by almost 19 tonnes per person per year, which is more than the per-capita output of the US (and we’re hardly models of efficiency)—at absolutely no cost in GDP.

Then there are countries like Mongolia, which produces only $12,500 in GDP but 14.5 tonnes of CO2 per person per year. Mongolia is far above and to the left of the point of the Wedge, meaning that they could both increase their GDP and decrease their emissions by adopting the model of more efficient countries. Telling these countries that “degrowth” is the answer is beyond perverse—cut Mongolia’s GDP by 2/3 and you would throw them into poverty without even bringing carbon emissions down to target.

We don’t need to overthrow capitalism or even give up on GDP growth in general. We need to focus on carbon, carbon, carbon: All economic policy from this point forward should be made with CO2 reduction in mind. If that means reducing GDP, we may have to accept that; but often it won’t. Switching to nuclear power and public transit would dramatically reduce emissions but need have no harmful effect on economic output—in fact, the large investment required could pull a country out of recession.

Don’t worry about the Doughnut. Aim for the point of the Wedge.
