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.

Russia has invaded Ukraine.

Mar 6 JDN 2459645

Russia has invaded Ukraine. No doubt you have heard it by now, as it’s all over the news now in dozens of outlets, from CNN to NBC to The Guardian to Al-Jazeera. And as well it should be, as this is the first time in history that a nuclear power has annexed another country. Yes, nuclear powers have fought wars before—the US just got out of one in Afghanistan as you may recall. They have even started wars and led invasions—the US did that in Iraq. And certainly, countries have been annexing and conquering other countries for millennia. But never before—never before, in human historyhas a nuclear-armed state invaded another country simply to claim it as part of itself. (Trump said he thought the US should have done something like that, and the world was rightly horrified.)

Ukraine is not a nuclear power—not anymore. The Soviet Union built up a great deal of its nuclear production in Ukraine, and in 1991 when Ukraine became independent it still had a sizable nuclear arsenal. But starting in 1994 Ukraine began disarming that arsenal, and now it is gone. Now that Russia has invaded them, the government of Ukraine has begun publicly reconsidering their agreements to disarm their nuclear arsenal.

Russia’s invasion of Ukraine has just disproved the most optimistic models of international relations, which basically said that major power wars for territory were over at the end of WW2. Some thought it was nuclear weapons, others the United Nations, still others a general improvement in trade integration and living standards around the world. But they’ve all turned out to be wrong; maybe such wars are rarer, but they can clearly still happen, because one just did.

I would say that only two major theories of the Long Peace are still left standing in light of this invasion, and that is nuclear deterrence and the democratic peace. Ukraine gave up its nuclear arsenal and later got attacked—that’s consistent with nuclear deterrence. Russia under Putin is nearly as authoritarian as the Soviet Union, and Ukraine is a “hybrid regime” (let’s call it a solid D), so there’s no reason the democratic peace would stop this invasion. But any model which posits that trade or the UN prevent war is pretty much off the table now, as Ukraine had very extensive trade with both Russia and the EU and the UN has been utterly toothless so far. (Maybe we could say the UN prevents wars except those led by permanent Security Council members.)

Well, then, what if the nuclear deterrence theory is right? What would have happened if Ukraine had kept its nuclear weapons? Would that have made this situation better, or worse? It could have made it better, if it acted as a deterrent against Russian aggression. But it could also have made it much, much worse, if it resulted in a nuclear exchange between Russia and Ukraine.

This is the problem with nukes. They are not a guarantee of safety. They are a guarantee of fat tails. To explain what I mean by that, let’s take a brief detour into statistics.

A fat-tailed distribution is one for which very extreme events have non-negligible probability. For some distributions, like a uniform distribution, events are clearly contained within a certain interval and nothing outside is even possible. For others, like a normal distribution or lognormal distribution, extreme events are theoretically possible, but so vanishingly improbable they aren’t worth worrying about. But for fat-tailed distributions like a Cauchy distribution or a Pareto distribution, extreme events are not so improbable. They may be unlikely, but they are not so unlikely they can simply be ignored. Indeed, they can actually dominate the average—most of what happens, happens in a handful of extreme events.

Deaths in war seem to be fat-tailed, even in conventional warfare. They seem to follow a Pareto distribution. There are lots of tiny skirmishes, relatively frequent regional conflicts, occasional major wars, and a handful of super-deadly global wars. This kind of pattern tends to emerge when a phenomenon is self-reinforcing by positive feedback—hence why we also see it in distributions of income and wildfire intensity.

Fat-tailed distributions typically (though not always—it’s easy to construct counterexamples, like the Cauchy distribution with low values truncated off) have another property as well, which is that minor events are common. More common, in fact, than they would be under a normal distribution. What seems to happen is that the probability mass moves away from the moderate outcomes and shifts to both the extreme outcomes and the minor ones.

Nuclear weapons fit this pattern perfectly. They may in fact reduce the probability of moderate, regional conflicts, in favor of increasing the probability of tiny skirmishes or peaceful negotiations. But they also increase the probability of utterly catastrophic outcomes—a full-scale nuclear war could kill billions of people. It probably wouldn’t wipe out all of humanity, and more recent analyses suggest that a catastrophic “nuclear winter” is unlikely. But even 2 billion people dead would be literally the worst thing that has ever happened, and nukes could make it happen in hours when such a death toll by conventional weapons would take years.

If we could somehow guarantee that such an outcome would never occur, then the lower rate of moderate conflicts nuclear weapons provide would justify their existence. But we can’t. It hasn’t happened yet, but it doesn’t have to happen often to be terrible. Really, just once would be bad enough.

Let us hope, then, that the democratic peace turns out to be the theory that’s right. Because a more democratic world would clearly be better—while a more nuclearized world could be better, but could also be much, much worse.

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.
