Are people basically good?

Mar 20 JDN 2459659

I recently finished reading Human Kind by Rutger Bregman. His central thesis is a surprisingly controversial one, yet one I largely agree with: People are basically good. Most people, in most circumstances, try to do the right thing.

Neoclassical economists in particular seem utterly scandalized by any such suggestion. No, they insist, people are selfish! They’ll take any opportunity to exploit each other! On this, Bregman is right and the neoclassical economists are wrong.

One of the best parts of the book is Bregman’s tale of several shipwrecked Tongan boys who were stranded on the remote island of ‘Ata, sometimes called “the real Lord of the Flies but with an outcome quite radically different from that of the novel. There were of course conflicts during their long time stranded, but the boys resolved most of these conflicts peacefully, and by the time help came over a year later they were still healthy and harmonious. Bregman himself was involved in the investigative reporting about these events, and his tale of how he came to meet some of the (now elderly) survivors and tell their tale is both enlightening and heartwarming.

Bregman spends a lot of time (perhaps too much time) analyzing classic experiments meant to elucidate human nature. He does a good job of analyzing the Milgram experiment—it’s valid, but it says more about our willingness to serve a cause than our blind obedience to authority. He utterly demolishes the Zimbardo experiment; I knew it was bad, but I hadn’t even realized how utterly worthless that so-called “experiment” actually is. Zimbardo basically paid people to act like abusive prison guards—specifically instructing them how to act!—and then claimed that he had discovered something deep in human nature. Bregman calls it a “hoax”, which might be a bit too strong—but it’s about as accurate as calling it an “experiment”. I think it’s more like a form of performance art.

Bregman’s criticism of Steven Pinker I find much less convincing. He cites a few other studies that purported to show the following: (1) the archaeological record is unreliable in assessing death rates in prehistoric societies (fair enough, but what else do we have?), (2) the high death rates in prehistoric cultures could be from predators such as lions rather than other humans (maybe, but that still means civilization is providing vital security!), (3) the Long Peace could be a statistical artifact because data on wars is so sparse (I find this unlikely, but I admit the Russian invasion of Ukraine does support such a notion), or (4) the Long Peace is the result of nuclear weapons, globalized trade, and/or international institutions rather than a change in overall attitudes toward violence (perfectly reasonable, but I’m not even sure Pinker would disagree).

I appreciate that Bregman does not lend credence to the people who want to use absolute death counts instead of relative death rates, who apparently would rather live in a prehistoric village of 100 people that gets wiped out by a plague (or for that matter on a Mars colony of 100 people who all die of suffocation when the life support fails) rather than remain in a modern city of a million people that has a few dozen murders each year. Zero homicides is better than 40, right? Personally, I care most about the question “How likely am I to die at any given time?”; and for that, relative death rates are the only valid measure. I don’t even see why we should particularly care about homicide versus other causes of death—I don’t see being shot as particularly worse than dying of Alzheimer’s (indeed, quite the contrary, other than the fact that Alzheimer’s is largely limited to old age and shooting isn’t). But all right, if violence is the question, then go ahead and use homicides—but it certainly should be rates and not absolute numbers. A larger human population is not an inherently bad thing.

I even appreciate that Bregman offers a theory (not an especially convincing one, but not an utterly ridiculous one either) of how agriculture and civilization could emerge even if hunter-gatherer life was actually better. It basically involves agriculture being discovered by accident, and then people gradually transitioning to a sedentary mode of life and not realizing their mistake until generations had passed and all the old skills were lost. There are various holes one can poke in this theory (Were the skills really lost? Couldn’t they be recovered from others? Indeed, haven’t people done that, in living memory, by “going native”?), but it’s at least better than simply saying “civilization was a mistake”.

Yet Bregman’s own account, particularly his discussion of how early civilizations all seem to have been slave states, seems to better support what I think is becoming the historical consensus, which is that civilization emerged because a handful of psychopaths gathered armies to conquer and enslave everyone around them. This is bad news for anyone who holds to a naively Whiggish view of history as a continuous march of progress (which I have oft heard accused but rarely heard endorsed), but it’s equally bad news for anyone who believes that all human beings are basically good and we should—or even could—return to a state of blissful anarchism.

Indeed, this is where Bregman’s view and mine part ways. We both agree that most people are mostly good most of the time. He even acknowledges that about 2% of people are psychopaths, which is a very plausible figure. (The figures I find most credible are about 1% of women and about 4% of men, which averages out to 2.5%. The prevalence you get also depends on how severely lacking in empathy someone needs to be in order to qualify. I’ve seen figures as low as 1% and as high as 4%.) What he fails to see is how that 2% of people can have large effects on society, wildly disproportionate to their number.

Consider the few dozen murders that are committed in any given city of a million people each year. Who is committing those murders? By and large, psychopaths. That’s more true of premeditated murder than of crimes of passion, but even the latter are far more likely to be committed by psychopaths than the general population.

Or consider those early civilizations that were nearly all authoritarian slave-states. What kind of person tends to govern an authoritarian slave-state? A psychopath. Sure, probably not every Roman emperor was a psychopath—but I’m quite certain that Commodus and Caligula were, and I suspect that Augustus and several others were as well. And the ones who don’t seem like psychopaths (like Marcus Aurelius) still seem like narcissists. Indeed, I’m not sure it’s possible to be an authoritarian emperor and not be at least a narcissist; should an ordinary person somehow find themselves in the role, I think they’d immediately set out to delegate authority and improve civil liberties.

This suggests that civilization was not so much a mistake as it was a crime—civilization was inflicted upon us by psychopaths and their greed for wealth and power. Like I said, not great for a “march of progress” view of history. Yet a lot has changed in the last few thousand years, and life in the 21st century at least seems overall pretty good—and almost certainly better than life on the African savannah 50,000 years ago.

In essence, what I think happened was we invented a technology to turn the tables of civilization, use the same tools psychopaths had used to oppress us as a means to contain them. This technology was called democracy. The institutions of democracy allowed us to convert government from a means by which psychopaths oppress and extract wealth from the populace to a means by which the populace could prevent psychopaths from committing wanton acts of violence.

Is it perfect? Certainly not. Indeed, there are many governments today that much better fit the “psychopath oppressing people” model (e.g. Russia, China, North Korea), and even in First World democracies there are substantial abuses of power and violations of human rights. In fact, psychopaths are overrepresented among the police and also among politicians. Perhaps there are superior modes of governance yet to be found that would further reduce the power psychopaths have and thereby make life better for everyone else.

Yet it remains clear that democracy is better than anarchy. This is not so much because anarchy results in everyone behaving badly and causes immediate chaos (as many people seem to erroneously believe), but because it results in enough people behaving badly to be a problem—and because some of those people are psychopaths who will take advantage of power vacuum to seize control for themselves.

Yes, most people are basically good. But enough people aren’t that it’s a problem.

Bregman seems to think that simply outnumbering the psychopaths is enough to keep them under control, but history clearly shows that it isn’t. We need institutions of governance to protect us. And for the most part, First World democracies do a fairly good job of that.

Indeed, I think Bregman’s perspective may be a bit clouded by being Dutch, as the Netherlands has one of the highest rates of trust in the world. Nearly 90% of people in the Netherlands trust their neighbors. Even the US has high levels of trust by world standards, at about 84%; a more typical country is India or Mexico at 64%, and the least-trusting countries are places like Gabon with 31% or Benin with a dismal 23%. Trust in government varies widely, from an astonishing 94% in Norway (then again, have you seen Norway? Their government is doing a bang-up job!) to 79% in the Netherlands, to closer to 50% in most countries (in this the US is more typical), all the way down to 23% in Nigeria (which seems equally justified). Some mysteries remain, like why more people trust the government in Russia than in Namibia. (Maybe people in Namibia are just more willing to speak their minds? They’re certainly much freer to do so.)

In other words, Dutch people are basically good. Not that the Netherlands has no psychopaths; surely they have a few just like everyone else. But they have strong, effective democratic institutions that provide both liberty and security for the vast majority of the population. And with the psychopaths under control, everyone else can feel free to trust each other and cooperate, even in the absence of obvious government support. It’s precisely because the government of the Netherlands is so unusually effective that someone living there can come to believe that government is unnecessary.

In short, Bregman is right that we should have donation boxes—and a lot of people seem to miss that (especially economists!). But he seems to forget that we need to keep them locked.

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.

Pinker Propositions

May 19 2458623

What do the following statements have in common?

1. “Capitalist countries have less poverty than Communist countries.

2. “Black men in the US commit homicide at a higher rate than White men.

3. “On average, in the US, Asian people score highest on IQ tests, White and Hispanic people score near the middle, and Black people score the lowest.

4. “Men on average perform better at visual tasks, and women on average perform better on verbal tasks.

5. “In the United States, White men are no more likely to be mass shooters than other men.

6. “The genetic heritability of intelligence is about 60%.

7. “The plurality of recent terrorist attacks in the US have been committed by Muslims.

8. “The period of US military hegemony since 1945 has been the most peaceful period in human history.

These statements have two things in common:

1. All of these statements are objectively true facts that can be verified by rich and reliable empirical data which is publicly available and uncontroversially accepted by social scientists.

2. If spoken publicly among left-wing social justice activists, all of these statements will draw resistance, defensiveness, and often outright hostility. Anyone making these statements is likely to be accused of racism, sexism, imperialism, and so on.

I call such propositions Pinker Propositions, after an excellent talk by Steven Pinker illustrating several of the above statements (which was then taken wildly out of context by social justice activists on social media).

The usual reaction to these statements suggests that people think they imply harmful far-right policy conclusions. This inference is utterly wrong: A nuanced understanding of each of these propositions does not in any way lead to far-right policy conclusions—in fact, some rather strongly support left-wing policy conclusions.

1. Capitalist countries have less poverty than Communist countries, because Communist countries are nearly always corrupt and authoritarian. Social democratic countries have the lowest poverty and the highest overall happiness (#ScandinaviaIsBetter).

2. Black men commit more homicide than White men because of poverty, discrimination, mass incarceration, and gang violence. Black men are also greatly overrepresented among victims of homicide, as most homicide is intra-racial. Homicide rates often vary across ethnic and socioeconomic groups, and these rates vary over time as a result of cultural and political changes.

3. IQ tests are a highly imperfect measure of intelligence, and the genetics of intelligence cut across our socially-constructed concept of race. There is far more within-group variation in IQ than between-group variation. Intelligence is not fixed at birth but is affected by nutrition, upbringing, exposure to toxins, and education—all of which statistically put Black people at a disadvantage. Nor does intelligence remain constant within populations: The Flynn Effect is the well-documented increase in intelligence which has occurred in almost every country over the past century. Far from justifying discrimination, these provide very strong reasons to improve opportunities for Black children. The lead and mercury in Flint’s water suppressed the brain development of thousands of Black children—that’s going to lower average IQ scores. But that says nothing about supposed “inherent racial differences” and everything about the catastrophic damage of environmental racism.

4. To be quite honest, I never even understood why this one shocks—or even surprises—people. It’s not even saying that men are “smarter” than women—overall IQ is almost identical. It’s just saying that men are more visual and women are more verbal. And this, I think, is actually quite obvious. I think the clearest evidence of this—the “interocular trauma” that will convince you the effect is real and worth talking about—is pornography. Visual porn is overwhelmingly consumed by men, even when it was designed for women (e.g. Playgirla majority of its readers are gay men, even though there are ten times as many straight women in the world as there are gay men). Conversely, erotic novels are overwhelmingly consumed by women. I think a lot of anti-porn feminism can actually be explained by this effect: Feminists (who are usually women, for obvious reasons) can say they are against “porn” when what they are really against is visual porn, because visual porn is consumed by men; then the kind of porn that they like (erotic literature) doesn’t count as “real porn”. And honestly they’re mostly against the current structure of the live-action visual porn industry, which is totally reasonable—but it’s a far cry from being against porn in general. I have some serious issues with how our farming system is currently set up, but I’m not against farming.

5. This one is interesting, because it’s a lack of a race difference, which normally is what the left wing always wants to hear. The difference of course is that this alleged difference would make White men look bad, and that’s apparently seen as a desirable goal for social justice. But the data just doesn’t bear it out: While indeed most mass shooters are White men, that’s because most Americans are White, which is a totally uninteresting reason. There’s no clear evidence of any racial disparity in mass shootings—though the gender disparity is absolutely overwhelming: It’s almost always men.

6. Heritability is a subtle concept; it doesn’t mean what most people seem to think it means. It doesn’t mean that 60% of your intelligence is due to your your genes. Indeed, I’m not even sure what that sentence would actually mean; it’s like saying that 60% of the flavor of a cake is due to the eggs. What this heritability figure actually means that when you compare across individuals in a population, and carefully control for environmental influences, you find that about 60% of the variance in IQ scores is explained by genetic factors. But this is within a particular population—here, US adults—and is absolutely dependent on all sorts of other variables. The more flexible one’s environment becomes, the more people self-select into their preferred environment, and the more heritable traits become. As a result, IQ actually becomes more heritable as children become adults, called the Wilson Effect.

7. This one might actually have some contradiction with left-wing policy. The disproportionate participation of Muslims in terrorism—controlling for just about anything you like, income, education, age etc.—really does suggest that, at least at this point in history, there is some real ideological link between Islam and terrorism. But the fact remains that the vast majority of Muslims are not terrorists and do not support terrorism, and antagonizing all the people of an entire religion is fundamentally unjust as well as likely to backfire in various ways. We should instead be trying to encourage the spread of more tolerant forms of Islam, and maintaining the strict boundaries of secularism to prevent the encroach of any religion on our system of government.

8. The fact that US military hegemony does seem to be a cause of global peace doesn’t imply that every single military intervention by the US is justified. In fact, it doesn’t even necessarily imply that any such interventions are justified—though I think one would be hard-pressed to say that the NATO intervention in the Kosovo War or the defense of Kuwait in the Gulf War was unjustified. It merely points out that having a hegemon is clearly preferable to having a multipolar world where many countries jockey for military supremacy. The Pax Romana was a time of peace but also authoritarianism; the Pax Americana is better, but that doesn’t prevent us from criticizing the real harms—including major war crimes—committed by the United States.

So it is entirely possible to know and understand these facts without adopting far-right political views.

Yet Pinker’s point—and mine—is that by suppressing these true facts, by responding with hostility or even ostracism to anyone who states them, we are actually adding fuel to the far-right fire. Instead of presenting the nuanced truth and explaining why it doesn’t imply such radical policies, we attack the messenger; and this leads people to conclude three things:

1. The left wing is willing to lie and suppress the truth in order to achieve political goals (they’re doing it right now).

2. These statements actually do imply right-wing conclusions (else why suppress them?).

3. Since these statements are true, that must mean the right-wing conclusions are actually correct.

Now (especially if you are someone who identifies unironically as “woke”), you might be thinking something like this: “Anyone who can be turned away from social justice so easily was never a real ally in the first place!”

This is a fundamentally and dangerously wrongheaded view. No one—not me, not you, not anyone—was born believing in social justice. You did not emerge from your mother’s womb ranting against colonalist imperialism. You had to learn what you now know. You came to believe what you now believe, after once believing something else that you now think is wrong. This is true of absolutely everyone everywhere. Indeed, the better you are, the more true it is; good people learn from their mistakes and grow in their knowledge.

This means that anyone who is now an ally of social justice once was not. And that, in turn, suggests that many people who are currently not allies could become so, under the right circumstances. They would probably not shift all at once—as I didn’t, and I doubt you did either—but if we are welcoming and open and honest with them, we can gradually tilt them toward greater and greater levels of support.

But if we reject them immediately for being impure, they never get the chance to learn, and we never get the chance to sway them. People who are currently uncertain of their political beliefs will become our enemies because we made them our enemies. We declared that if they would not immediately commit to everything we believe, then they may as well oppose us. They, quite reasonably unwilling to commit to a detailed political agenda they didn’t understand, decided that it would be easiest to simply oppose us.

And we don’t have to win over every person on every single issue. We merely need to win over a large enough critical mass on each issue to shift policies and cultural norms. Building a wider tent is not compromising on your principles; on the contrary, it’s how you actually win and make those principles a reality.

There will always be those we cannot convince, of course. And I admit, there is something deeply irrational about going from “those leftists attacked Charles Murray” to “I think I’ll start waving a swastika”. But humans aren’t always rational; we know this. You can lament this, complain about it, yell at people for being so irrational all you like—it won’t actually make people any more rational. Humans are tribal; we think in terms of teams. We need to make our team as large and welcoming as possible, and suppressing Pinker Propositions is not the way to do that.

To truly honor veterans, end war

JDN 2457339 EST 20:00 (Nov 11, 2015)

Today is Veterans’ Day, on which we are asked to celebrate the service of military veterans, particularly those who have died as a result of war. We tend to focus on those who die in combat, but actually these have always been relatively uncommon; throughout history, most soldiers have died later of their wounds or of infections. More recently as a result of advances in body armor and medicine, actually relatively few soldiers die even of war wounds or infections—instead, they are permanently maimed and psychologically damaged, and the most common way that war kills soldiers now is by making them commit suicide.

Even adjusting for the fact that soldiers are mostly young men (the group of people most likely to commit suicide), military veterans still have about 50 excess suicides per million people per year, for a total of about 300 suicides per million per year. Using the total number, that’s over 8000 veteran suicides per year, or 22 per day. Using only the excess compared to men of the same ages, it’s still an additional 1300 suicides per year.

While the 14-years-and-counting Afghanistan War has killed 2,271 American soldiers and the 11-year Iraq War has killed 4,491 American soldiers directly (or as a result of wounds), during that same time period from 2001 to 2015 there have been about 18,000 excess suicides as a result of the military—excess in the sense that they would not have occurred if those men had been civilians. Altogether that means there would be nearly 25,000 additional American soldiers alive today were it not for these two wars.

War does not only kill soldiers while they are on the battlefield—indeed, most of the veterans it kills die here at home.

There is a reason Woodrow Wilson chose November 11 as the date for Veterans’ Day: It was on this day in 1918 that World War 1, up to that point the war that had caused the most deaths in human history, was officially ended. Sadly, it did not remain the deadliest war, but was surpassed by World War 2 a generation later. Fortunately, no other war has ever exceeded World War 2—at least, not yet.

We tend to celebrate holidays like this with a lot of ritual and pageantry (or even in the most inane and American way possible, with free restaurant meals and discounts on various consumer products), and there’s nothing inherently wrong with that. Nor is there anything wrong with taking a moment to salute the flag or say “Thank you for your service.” But that is not how I believe veterans should be honored. If I were a veteran, that is not how I would want to be honored.

We are getting much closer to how I think they should be honored when the White House announces reforms at Veterans’ Affairs hospitals and guaranteed in-state tuition at public universities for families of veterans—things that really do in a concrete and measurable way improve the lives of veterans and may even save some of them from that cruel fate of suicide.

But ultimately there is only one way that I believe we can truly honor veterans and the spirit of the holiday as Wilson intended it, and that is to end war once and for all.

Is this an ambitious goal? Absolutely. But is it an impossible dream? I do not believe so.

In just the last half century, we have already made most of the progress that needed to be made. In this brilliant video animation, you can see two things: First, the mind-numbingly horrific scale of World War 2, the worst war in human history; but second, the incredible progress we have made since then toward world peace. It was as if the world needed that one time to be so unbearably horrible in order to finally realize just what war is and why we need a better way of solving conflicts.

This is part of a very long-term trend in declining violence, for a variety of reasons that are still not thoroughly understood. In simplest terms, human beings just seem to be getting better at not killing each other.

Nassim Nicholas Taleb argues that this is just a statistical illusion, because technologies like nuclear weapons create the possibility of violence on a previously unimaginable scale, and it simply hasn’t happened yet. For nuclear weapons in particular, I think he may be right—the consequences of nuclear war are simply so catastrophic that even a small risk of it is worth paying almost any price to avoid.

Fortunately, nuclear weapons are not necessary to prevent war: South Africa has no designs on attacking Japan anytime soon, but neither has nuclear weapons. Germany and Poland lack nuclear arsenals and were the first countries to fight in World War 2, but now that both are part of the European Union, war between them today seems almost unthinkable. When American commentators fret about China today it is always about wage competition and Treasury bonds, not aircraft carriers and nuclear missiles. Conversely, North Korea’s acquisition of nuclear weapons has by no means stabilized the region against future conflicts, and the fact that India and Pakistan have nuclear missiles pointed at one another has hardly prevented them from killing each other over Kashmir. We do not need nuclear weapons as a constant threat of annihilation in order to learn to live together; political and economic ties achieve that goal far more reliably.

And I think Taleb is wrong about the trend in general. He argues that the only reason violence is declining is that concentration of power has made violence rarer but more catastrophic when it occurs. Yet we know that many forms of violence which used to occur no longer do, not because of the overwhelming force of a Leviathan to prevent them, but because people simply choose not to do them anymore. There are no more gladiator fights, no more cat-burnings, no more public lynchings—not because of the expansion in government power, but because our society seems to have grown out of that phase.

Indeed, what horrifies us about ISIS and Boko Haram would have been considered quite normal, even civilized, in the Middle Ages. (If you’ve ever heard someone say we should “bring back chivalry”, you should explain to them that the system of knight chivalry in the 12th century had basically the same moral code as ISIS today—one of the commandments Gautier’s La Chevalerie attributes as part of the chivalric code is literally “Thou shalt make war against the infidel without cessation and without mercy.”) It is not so much that they are uniquely evil by historical standards, as that we grew out of that sort of barbaric violence awhile ago but they don’t seem to have gotten the memo.

In fact, one thing people don’t seem to understand about Steven Pinker’s argument about this “Long Peace” is that it still works if you include the world wars. The reason World War 2 killed so many people was not that it was uniquely brutal, nor even simply because its weapons were more technologically advanced. It also had to do with the scale of integration—we called it a single war even though it involved dozens of countries because those countries were all united into one of two sides, whereas in centuries past that many countries could be constantly fighting each other in various combinations but it would never be called the same war. But the primary reason World War 2 killed the largest raw number of people was simply because the world population was so much larger. Controlling for world population, World War 2 was not even among the top 5 worst wars—it barely makes the top 10. The worst war in history by proportion of the population killed was almost certainly the An Lushan Rebellion in 8th century China, which many of you may not even have heard of until today.

Though it may not seem so as ISIS kidnaps Christians and drone strikes continue, shrouded in secrecy, we really are on track to end war. Not today, not tomorrow, maybe not in any of our lifetimes—but someday, we may finally be able to celebrate Veterans’ Day as it was truly intended: To honor our soldiers by making it no longer necessary for them to die.
