A knockdown proof of social preferences

Apr 27 JDN 2460793

In economics jargon, social preferences basically just means that people care about what happens to people other than themselves.

If you are not an economist, it should be utterly obvious that social preferences exist:

People generally care the most about their friends and family, less but still a lot about their neighbors and acquaintances, less but still moderately about other groups they belong to such as those delineated by race, gender, religion, and nationality (or for that matter alma mater), and less still but not zero about any randomly-selected human being. Most of us even care about the welfare of other animals, though we can be curiously selective about this: Abuse that would horrify most people if done to cats or dogs passes more or less ignored when it is committed against cows, pigs, and chickens.

For some people, there are also groups for which there seem to be negative social preferences, sometimes called “spiteful preferences”, but that doesn’t really seem to capture it: I think we need a stronger word like hatredfor whatever emotion human beings feel when they are willing and eager to participate in genocide. Yet even that is still a social preference: If you want someone to suffer or die, you do care about what happens to them.

But if you are an economist, you’ll know that the very idea of social preferences remains controversial, even after it has been clearly and explictly demonstrated by numerous randomized controlled experiments. (I will never forget the professor who put “altruism” in scare quotes in an email reply he sent me.)

Indeed, I have realized that the experimental evidence is so clear, so obvious, that it surprises me that I haven’t seen anyone present the really overwhelming knockdown evidence that ought to convince any reasonable skeptic. So that is what I have decided to do today.

Consider the following four economics experiments:

Dictator 1Participant 1 chooses an allocation of $20, dividing it between themself and Participant 2. Whatever allocation Participant 1 chooses, Participant 2 must accept. Both participants get their allocated amounts.
Dictator 2Participant 1 chooses an allocation of $20, choosing how much they get. Participant 1 gets their allocated amount. The rest of the money is burned.
Ultimatum 1Participant 1 chooses an allocation of $20, dividing it between themself and Participant 2. Participant 2 may choose to accept or reject this allocation; if they accept, both participants get their allocated amounts. If they reject, both participants get nothing.
Ultimatum 2Participant 1 chooses an allocation of $20, dividing it between themself and Participant 2. Participant 2 may choose to accept or reject this allocation; if they accept, both participants get their allocated amounts. If they reject, Participant 2 gets nothing, but Participant 1 still gets the allocated amount.

Dictator 1 and Ultimatum 1 are the standard forms of the Dictator Game and Ultimatum Game, which are experiments that have been conducted dozens if not hundreds of times and are the subject of a huge number of papers in experimental economics.

These experiments clearly demonstrate the existence of social preferences. But I think even most behavioral economists don’t quite seem to grasp just how compelling that evidence is.

This is because they have generally failed to compare against my other two experiments, Dictator 2 and Ultimatum 2.

If social preferences did not exist, Participant 1 would be completely indifferent about what happened to the money that they themself did not receive.

In that case, Dictator 1 and Dictator 2 should show the same result: Participant 1 chooses to get $20.

Likewise, Ultimatum 1 and Ultimatum 2 should show the same result: Participant 1 chooses to get $19, offering only $1 to Participant 2, and Participant 2 accepts. This is the outcome that is “rational” in the hyper-selfish neoclassical sense.

Much ink has already been spilled over the fact that these are not the typical outcomes of Dictator 1 and Ultimatum 1. Far more likely is that Participant 1 offers something close to $10, or even $10 exactly, in both games; and in Ultimatum 1, in the unlikely event that Participant 1 should offer only $1 or $2, Participant 2 will typically reject.

But what I’d like to point out today is that the “rational” neoclassical outcome is what would happen in Dictator 2 and Ultimatum 2, and that this is so obvious we probably don’t even need to run the experiments (but we might as well, just to be sure).

In Dictator 1, the money that Participant 1 doesn’t keep goes to Participant 2, and so they are deciding how to weigh their own interests against those of another. But in Dictator 2, Participant 1 is literally just deciding how much free money they will receive. The other money doesn’t go to anyone—not even back to the university conducting the experiment. It’s just burned. It provides benefit to no one. So the rational choice is in fact obvious: Take all of the free money. (Technically, burning money and thereby reducing the money supply would have a miniscule effect of reducing future inflation across the entire economy. But even the full $20 would be several orders of magnitude too small for anyone to notice—and even a much larger amount like $10 billion would probably end up being compensated by the actions of the Federal Reserve.)

Likewise, in both Ultimatum 1 and Ultimatum 2, the money that Participant 1 doesn’t keep will go to Participant 2. Their offer will thus probably be close to $10. But what I really want to focus in on is Participant 2’s choice: If they are offered only $1 or $2, will they accept? Neoclassical theory says that the “rational” choice is to accept it. But in Ultimatum 1, most people will reject it. Are they being irrational?

If they were simply being irrational—failing to maximize their own payoff—then they should reject just as often in Ultimatum 2. But I contend that they would in fact accept far more offers in Ultimatum 2 than they did in Ultimatum 1. Why? Because rejection doesn’t stop Participant 1 from getting what they demanded. There is no way to punish Participant 1 for an unfair offer in Ultimatum 2: It is literally just a question of whether you get $1 or $0.

Like I said, I haven’t actually run these experiments. I’m not sure anyone has. But these results seem very obvious, and I would be deeply shocked if they did not turn out the way I expect. (Perhaps as shocked as so many neoclassical economists were when they first saw the results of experiments on Dictator 1 and Ultimatum 1!)

Thus, Dictator 2 and Ultimatum 2 should have outcomes much more like what neoclassical economics predicts than Dictator 1 and Ultimatum 1.

Yet the only difference—the only difference—between Dictator 1 and Dictator 2, and between Ultimatum 1 and Ultimatum 2, is what happens to someone else’s payoff when you make your decision. Your own payoff is exactly identical.

Thus, behavior changes when we change only the effects on the payoffs of other people; therefore people care about the payoffs of others; therefore social preferences exist.

QED.

Of course this still leaves the question of what sort of social preferences people have, and why:

  • Why are some people more generous than others? Why are people sometimes spiteful—or even hateful?
  • Is it genetic? Is it evolutionary? Is it learned? Is it cultural? Likely all of the above.
  • Are people implicitly thinking of themselves as playing in a broader indefinitely iterated game called “life” and using that to influence their decisions? Quite possibly.
  • Is maintaining a reputation of being a good person important to people? In general, I’m sure it is, but I don’t think it can explain the results of these economic experiments by itself—especially in versions where everything is completely anonymous.

But given the stark differences between Dictator 1 versus Dictator 2 and Ultimatum 1 versus Ultimatum 2 (and really, feel free to run the experiments!), I don’t think anyone can reasonably doubt that social preferences do, in fact, exist.

If you ever find someone who does doubt social preferences, point them to this post.

How Effective Altruism hurt me

May 12 JDN 2460443

I don’t want this to be taken the wrong way. I still strongly believe in the core principles of Effective Altruism. Indeed, it’s shockingly hard to deny them, because basically they come out to this:

Doing more good is better than doing less good.

Then again, most people want to do good. Basically everyone agrees that more good is better than less good. So what’s the big deal about Effective Altruism?

Well, in practice, most people put shockingly little effort into trying to ensure that they are doing the most good they can. A lot of people just try to be nice people, without ever concerning themselves with the bigger picture. Many of these people don’t give to charity at all.

Then, even among people who do give to charity, typically give to charities more or less at random—or worse, in proportion to how much mail those charities send them begging for donations. (Surely you can see how that is a perverse incentive?) They donate to religious organizations, which sometimes do good things, but fundamentally are founded upon ignorance, patriarchy, and lies.

Effective Altruism is a movement intended to fix this, to get people to see the bigger picture and focus their efforts on where they will do the most good. Vet charities not just for their honesty, but also their efficiency and cost-effectiveness:

Just how many mQALY can you buy with that $1?

That part I still believe in. There is a lot of value in assessing which charities are the most effective, and trying to get more people to donate to those high-impact charities.

But there is another side to Effective Altruism, which I now realize has severely damaged my mental health.

That is the sense of obligation to give as much as you possibly can.

Peter Singer is the most extreme example of this. He seems to have mellowed—a little—in more recent years, but in some of his most famous books he uses the following thought experiment:

To challenge my students to think about the ethics of what we owe to people in need, I ask them to imagine that their route to the university takes them past a shallow pond. One morning, I say to them, you notice a child has fallen in and appears to be drowning. To wade in and pull the child out would be easy but it will mean that you get your clothes wet and muddy, and by the time you go home and change you will have missed your first class.

I then ask the students: do you have any obligation to rescue the child? Unanimously, the students say they do. The importance of saving a child so far outweighs the cost of getting one’s clothes muddy and missing a class, that they refuse to consider it any kind of excuse for not saving the child. Does it make a difference, I ask, that there are other people walking past the pond who would equally be able to rescue the child but are not doing so? No, the students reply, the fact that others are not doing what they ought to do is no reason why I should not do what I ought to do.

Basically everyone agrees with this particular decision: Even if you are wearing a very expensive suit that will be ruined, even if you’ll miss something really important like a job interview or even a wedding—most people agree that if you ever come across a drowning child, you should save them.

(Oddly enough, when contemplating this scenario, nobody ever seems to consider the advice that most lifeguards give, which is to throw a life preserver and then go find someone qualified to save the child—because saving someone who is drowning is a lot harder and a lot riskier than most people realize. (“Reach or throw, don’t go.”) But that’s a bit beside the point.)

But Singer argues that we are basically in this position all the time. For somewhere between $500 and $3000, you—yes, you—could donate to a high-impact charity, and thereby save a child’s life.

Does it matter that many other people are better positioned to donate than you are? Does it matter that the child is thousands of miles away and you’ll never see them? Does it matter that there are actually millions of children, and you could never save them all by yourself? Does it matter that you’ll only save a child in expectation, rather than saving some specific child with certainty?

Singer says that none of this matters. For a long time, I believed him.

Now, I don’t.

For, if you actually walked by a drowning child that you could save, only at the cost of missing a wedding and ruining your tuxedo, you clearly should do that. (If it would risk your life, maybe not—and as I alluded to earlier, that’s more likely than you might imagine.) If you wouldn’t, there’s something wrong with you. You’re a bad person.

But most people don’t donate everything they could to high-impact charities. Even Peter Singer himself doesn’t. So if donating is the same as saving the drowning child, it follows that we are all bad people.

(Note: In general, if an ethical theory results in the conclusion that the whole of humanity is evil, there is probably something wrong with that ethical theory.)

Singer has tried to get out of this by saying we shouldn’t “sacrifice things of comparable importance”, and then somehow cash out what “comparable importance” means in such a way that it doesn’t require you to live on the street and eat scraps from trash cans. (Even though the people you’d be donating to largely do live that way.)

I’m not sure that really works, but okay, let’s say it does. Even so, it’s pretty clear that anything you spend money on purely for enjoyment would have to go. You would never eat out at restaurants, unless you could show that the time saved allowed you to get more work done and therefore donate more. You would never go to movies or buy video games, unless you could show that it was absolutely necessary for your own mental functioning. Your life would be work, work, work, then donate, donate, donate, and then do the absolute bare minimum to recover from working and donating so you can work and donate some more.

You would enslave yourself.

And all the while, you’d believe that you were never doing enough, you were never good enough, you are always a terrible person because you try to cling to any personal joy in your own life rather than giving, giving, giving all you have.

I now realize that Effective Altruism, as a movement, had been basically telling me to do that. And I’d been listening.

I now realize that Effective Altruism has given me this voice in my head, which I hear whenever I want to apply for a job or submit work for publication:

If you try, you will probably fail. And if you fail, a child will die.

The “if you try, you will probably fail” is just an objective fact. It’s inescapable. Any given job application or writing submission will probably fail.

Yes, maybe there’s some sort of bundling we could do to reframe that, as I discussed in an earlier post. But basically, this is correct, and I need to accept it.

Now, what about the second part? “If you fail, a child will die.” To most of you, that probably sounds crazy. And it is crazy. It’s way more pressure than any ordinary person should have in their daily life. This kind of pressure should be reserved for neurosurgeons and bomb squads.

But this is essentially what Effective Altruism taught me to believe. It taught me that every few thousand dollars I don’t donate is a child I am allowing to die. And since I can’t donate what I don’t have, it follows that every few thousand dollars I fail to get is another dead child.

And since Effective Altruism is so laser-focused on results above all else, it taught me that it really doesn’t matter whether I apply for the job and don’t get it, or never apply at all; the outcome is the same, and that outcome is that children suffer and die because I had no money to save them.

I think part of the problem here is that Effective Altruism is utilitarian through and through, and utilitarianism has very little place for good enough. There is better and there is worse; but there is no threshold at which you can say that your moral obligations are discharged and you are free to live your life as you wish. There is always more good that you could do, and therefore always more that you should do.

Do we really want to live in a world where to be a good person is to owe your whole life to others?

I do not believe in absolute selfishness. I believe that we owe something to other people. But I no longer believe that we owe everything. Sacrificing my own well-being at the altar of altruism has been incredibly destructive to my mental health, and I don’t think I’m the only one.

By all means, give to high-impact charities. But give a moderate amount—at most, tithe—and then go live your life. You don’t owe the world more than that.

Time and How to Use It

Nov 5 JDN 2460254

A review of Four Thousand Weeks by Oliver Burkeman

The central message of Four Thousand Weeks: Time and How to Use It seems so obvious in hindsight it’s difficult to understand why it feels so new and unfamiliar. It’s a much-needed reaction to the obsessive culture of “efficiency” and “productivity” that dominates the self-help genre. Its core message is remarkable simple:

You don’t have time to do everything you want, so stop trying.

I actually think Burkeman understands the problem incorrectly. He argues repeatedly that it is our mortality which makes our lives precious—that it is because we only get four thousand weeks of life that we must use our time well. But this strikes me as just yet more making excuses for the dragon.

Our lives would not be less precious if we lived a thousand years or a million. Indeed, our time would hardly be any less scarce! You still can’t read every book ever written if you live a million years—for every one of those million years, another 500,000 books will be published. You could visit every one of the 10,000 cities in the world, surely; but if you spend a week in each one, by the time you get back to Paris for a second visit, centuries will have passed—I must imagine you’ll have missed quite a bit of change in that time. (And this assumes that our population remains the same—do we really think it would, if humans could live a million years?)

Even a truly immortal being that will live until the end of time needs to decide where to be at 7 PM this Saturday.

Yet Burkeman does grasp—and I fear that too many of us do not—that our time is precious, and when we try to do everything that seems worth doing, we end up failing to prioritize what really matters most.

What do most of us spend most of our lives doing? Whatever our bosses tell us to do. Aside from sleeping, the activity that human beings spend the largest chunk of their lives on is working.

This has made us tremendously, mind-bogglingly productive—our real GDP per capita is four times what it was in just 1950, and about eight times what it was in the 1920s. Projecting back further than that is a bit dicier, but assuming even 1% annual growth, it should be about twenty times what it was at the dawn of the Industrial Revolution. We could surely live better than medieval peasants did by working only a few hours per week; yet in fact on average we work more hours than they did—by some estimates, nearly twice as much. Rather than getting the same wealth for 5% of the work, or twice the wealth for 10%, we chose to get 40 times the wealth for twice the work.

It would be one thing if all this wealth and productivity actually seemed to make us happy. But does it?

Our physical health is excellent: We are tall, we live long lives—we are smarter, even, than people of the not-so-distant past. We have largely conquered disease as the ancients knew it. Even a ‘catastrophic’ global pandemic today kills a smaller share of the population than would die in a typical year from disease in ancient times. Even many of our most common physical ailments, such as obesity, heart disease, and diabetes, are more symptoms of abundance than poverty. Our higher rates of dementia and cancer are largely consequences of living longer lives—most medieval peasants simply didn’t make it long enough to get Alzheimer’s. I wonder sometimes how ancient people dealt with other common ailments such as migraine and sleep apnea; but my guess is that they basically just didn’t—since treatment was impossible, they learned to live with it. Maybe they consoled themselves with whatever placebo treatments the healers of their local culture offered.

Yet our mental health seems to be no better than ever—and depending on how you measure it, may actually be getting worse over time. Some of the measured increase is surely due to more sensitive diagnosis; but some of it may be a genuine increase—especially as a result of the COVID pandemic. I wasn’t able to find any good estimates of rates of depression or anxiety disorders in ancient or medieval times, so I guess I really can’t say whether this is a problem that’s getting worse. But it sure doesn’t seem to be getting better. We clearly have not solved the problem of depression the way we have solved the problem of infectious disease.

Burkeman doesn’t tell us to all quit our jobs and stop working. But he does suggest that if you are particularly unhappy at your current job (as I am), you may want to quit it and begin searching for something else (as I have). He reminds us that we often get stuck in a particular pattern and underestimate the possibilities that may be available to us.

And he has advice for those who want to stay in their current jobs, too: Do less. Don’t take on everything that is asked of you. Don’t work yourself to the bone. The rewards for working harder are far smaller than our society will tell you, and the costs of burning out are far higher. Do the work that is genuinely most important, and let the rest go.

Unlike most self-help books, Four Thousand Weeks offers very little in the way of practical advice. It’s more like a philosophical treatise, exhorting you to adopt a whole new outlook on time and how you use it. But he does offer a little bit of advice, near the end of the book, in “Ten Tools for Embracing Your Finitude” and “Five Questions”.

The ten tools are as follows:


Adopt a ‘fixed volume’ approach to productivity. Limit the number of tasks on your to-do list. Set aside a particular amount of time for productive work, and work only during that time.

I am relatively good at this one; I work only during certain hours on weekdays, and I resist the urge to work other times.

Serialize, serialize, serialize. Do one major project at a time.

I am terrible at this one; I constantly flit between different projects, leaving most of them unfinished indefinitely. But I’m not entirely convinced I’d do better trying to focus on one in particular. I switch projects because I get stalled on the current one, not because I’m anxious about not doing the others. Unless I can find a better way to break those stalls, switching projects still gets more done than staying stuck on the same one.

Decide in advance what to fail at. Prioritize your life and accept that some things will fail.

We all, inevitably, fail to achieve everything we want to. What Burkeman is telling us to do is choose in advance which achievements we will fail at. Ask yourself: How much do you really care about keeping the kitchen clean and the lawn mowed? If you’re doing these things to satisfy other people’s expectations but you don’t truly care about them yourself, maybe you should just accept that people will frown upon you for your messy kitchen and overgrown lawn.

Focus on what you’ve already completed, not just on what’s left to complete. Make a ‘done list’ of tasks you have completed today—even small ones like “brushed teeth” and “made breakfast”—to remind yourself that you do in fact accomplish things.

I may try this one for awhile. It feels a bit hokey to congratulate yourself on making breakfast—but when you are severely depressed, even small tasks like that can in fact feel like an ordeal.

Consolidate your caring. Be generous and kind, but pick your battles.

I’m not very good at this one either. Spending less time on social media has helped; I am no longer bombarded quite so constantly by worthy causes and global crises. Yet I still have a vague sense that I am not doing enough, that I should be giving more of myself to help others. For me this is partly colored by a feeling that I have failed to build a career that would have both allowed me to have direct impact on some issues and also made enough money to afford large donations.

Embrace boring and single-purpose technology. Downgrade your technology to reduce distraction.

I don’t do this one, but I also don’t see it as particularly good advice. Maybe taking Facebook and (the-platform-formerly-known-as-) Twitter off your phone home screen is a good idea. But the reason you go to social media isn’t that they are so easy to access. It’s that you are expected to, and that you try to use them to fill some kind of need in your life—though it’s unclear they ever actually fill it.

Seek out novelty in the mundane. Cultivate awareness and appreciation of the ordinary things around you.

This one is basically a stripped-down meditation technique. It does work, but it’s also a lot harder to do than most people seem to think. It is especially hard to do when you are severely depressed. One technique I’ve learned from therapy that is surprisingly helpful is to replace “I have to” with “I get to” whenever you can: You don’t have to scoop cat litter, you get to because you have an adorable cat. You don’t have to catch the bus to work, you get to because you have a job. You don’t have to make breakfast for your family, you get to because you have a loving family.

Be a ‘researcher’ in relationships. Cultivate curiosity rather than anxiety or judgment.

Human beings are tremendously varied and often unpredictable. If you worry about whether or not people will do what you want, you’ll be constantly worried. And I have certainly been there. It can help to try to take a stance of detachment, where you concern yourself less with getting the right outcome and more with learning about the people you are with. I think this can be taken too far—you can become totally detached from relationships, or you could put yourself in danger by failing to pass judgment on obviously harmful behaviors—but in moderation, it’s surprisingly powerful. The first time I ever enjoyed going to a nightclub, (at my therapist’s suggestion) I went as a social scientist, tasked with observing and cataloguing the behavior around me. I still didn’t feel fully integrated into the environment (and the music was still too damn loud!), but for once, I wasn’t anxious and miserable.

Cultivate instantaneous generosity. If you feel like doing something good for someone, just do it.

I’m honestly not sure whether this one is good advice. I used to follow it much more than I do now. Interacting with the Effective Altruism community taught me to temper these impulses, and instead of giving to every random charity or homeless person that asks for money, instead concentrate my donations into a few highly cost-effective charities. Objectively, concentrating donations in this way produces a larger positive impact on the world. But subjectively, it doesn’t feel as good, it makes people sad, and sometimes it can make you feel like a very callous person. Maybe there’s a balance to be had here: Give a little when the impulse strikes, but save up most of it for the really important donations.

Practice doing nothing.

This one is perhaps the most subversive, the most opposed to all standard self-help advice. Do nothing? Just rest? How can you say such a thing, when you just reminded us that we have only four thousand weeks to live? Yet this is in fact the advice most of us need to hear. We burn ourselves out because we forget how to rest.

I am also terrible at this one. I tend to get most anxious when I have between 15 and 45 minutes of free time before an activity, because 45 minutes doesn’t feel long enough to do anything, and 15 minutes feels too long to do nothing. Logically this doesn’t really make sense: Either you have time to do something, or you don’t. But it can be hard to find good ways to fill that sort of interval, because it requires the emotional overhead of starting and stopping a task.

Then, there are the five questions:

Where in your life or work are you currently pursuing comfort, when what’s called for is a little discomfort?

It seems odd to recommend discomfort as a goal, but I think what Burkeman is getting at is that we tend to get stuck in the comfortable and familiar, even when we would be better off reaching out and exploring into the unknown. I know that for me, finally deciding to quit this job was very uncomfortable; it required taking a big risk and going outside the familiar and expected. But I am now convinced it was the right decision.

Are you holding yourself to, and judging yourself by, standards of productivity or performance that are impossible to meet?

In a word? Yes. I’m sure I am. But this one is also slipperier than it may seem—for how do we really know what’s possible? And possible for whom? If you see someone else who seems to be living the life you think you want, is it just an illusion? Are they really suffering as badly as you? Or do they perhaps have advantages you don’t, which made it possible for them, but not for you? When people say they work 60 hours per week and you can barely manage 20, are they lying? Are you truly not investing enough effort? Or do you suffer from ailments they don’t, which make it impossible for you to commit those same hours?

In what ways have you yet to accept the fact that you are who you are, not the person you think you ought to be?

I think most of us have a lot of ways that we fail to accept ourselves: physically, socially, psychologically. We are never the perfect beings we aspire to be. And constantly aspiring to an impossible ideal will surely drain you. But I also fear that self-acceptance could be a dangerous thing: What if it makes us stop striving to improve? What if we could be better than we are, but we don’t bother? Would you want a murderous psychopath to practice self-acceptance? (Then again, do they already, whether we want them to or not?) How are we to know which flaws in ourselves should be accepted, and which repaired?

In which areas of your life are you still holding back until you feel like you know what you’re doing?

This one cut me very deep. I have several areas of my life where this accusation would be apt, and one in particular where I am plainly guilty as charged: Parenting. In a same-sex marriage, offspring don’t emerge automatically without intervention. If we want to have kids, we must do a great deal of work to secure adoption. And it has been much easier—safer, more comfortable—to simply put off that work, avoid the risk. I told myself we’d adopt once I finished grad school; but then I only got a temporary job, so I put it off again, saying we’d adopt once I found stability in my career. But what if I never find that stability? What if the rest of my career is always this precarious? What if I can always find some excuse to delay? The pain of never fulfilling that lifelong dream of parenthood might continue to gnaw at me forever.

How would you spend your days differently if you didn’t care so much about seeing your actions reach fruition?

This one is frankly useless. I hate it. It’s like when people say “What would you do if you knew you’d die tomorrow?” Obviously, you wouldn’t go to work, you wouldn’t pay your bills, you wouldn’t clean your bathroom. You might devote yourself single-mindedly to a single creative task you hoped to make a legacy, or gather your family and friends to share one last day of love, or throw yourself into meaningless hedonistic pleasure. Those might even be things worth doing, on occasion. But you can’t do them every day. If you knew you were about to die, you absolutely would not live in any kind of sustainable way.

Similarly, if I didn’t care about seeing my actions reach fruition, I would continue to write stories and never worry about publishing them. I would make little stabs at research when I got curious, then once it starts getting difficult or boring, give up and never bother writing the paper. I would continue flitting between a dozen random projects at once and never finish any of them. I might well feel happier—at least until it all came crashing down—but I would get absolutely nothing done.

Above all, I would never apply for any jobs, because applying for jobs is absolutely not about enjoying the journey. If you know for a fact that you won’t get an offer, you’re an idiot to bother applying. That is a task that is only worth doing if I believe that it will yield results—and indeed, a big part of why it’s so hard to bring myself to do it is that I have a hard time maintaining that belief.

If you read the surrounding context, Burkeman actually seems to intend something quite different than the actual question he wrote. He suggests devoting more time to big, long-term projects that require whole communities to complete. He likens this to laying bricks in a cathedral that we will never see finished.

I do think there is wisdom in this. But it isn’t a simple matter of not caring about results. Indeed, if you don’t care at all about whether the cathedral will stand, you won’t bother laying the bricks correctly. In some sense Burkeman is actually asking us to do the opposite: To care more about results, but specifically results that we may never live to see. Maybe he really intends to emphasize the word see—you care about your actions reaching fruition, but not whether or not you’ll ever see it.

Yet this, I am quite certain, is not my problem. When a psychiatrist once asked me, “What do you really want most in life?” I gave a very thoughtful answer: “To be remembered in a thousand years for my contribution to humanity.” (His response was glib: “You can’t control that.”) I still stand by that answer: If I could have whatever I want, no limits at all, three wishes from an all-powerful genie, two of them would be to solve some of the world’s greatest problems, and the third would be for the chance to live my life in a way that I knew would be forever remembered.

But I am slowly coming to realize that maybe I should abandon that answer. That psychiatrist’s answer was far too glib (he was in fact not a very good fit for me; I quickly switched to a different psychiatrist), but maybe it wasn’t fundamentally wrong. It may be impossible to predict, let alone control, whether our lives have that kind of lasting impact—and, almost by construction, most lives can’t.

Perhaps, indeed, I am too worried about whether the cathedral will stand. I only have a few bricks to lay myself, and while I can lay them the best I can, that ultimately will not be what decides the fate of the cathedral. A fire, or an earthquake, or simply some other bricklayer’s incompetence, could bring about its destruction—and there is nothing at all I can do to prevent that.

This post is already getting too long, so I should try to bring it to a close.

As the adage goes, perhaps if I had more time, I’d make it shorter.

How much should we give of ourselves?

Jul 23 JDN 2460149

This is a question I’ve written about before, but it’s a very important one—perhaps the most important question I deal with on this blog—so today I’d like to come back to it from a slightly different angle.

Suppose you could sacrifice all the happiness in the rest of your life, making your own existence barely worth living, in exchange for saving the lives of 100 people you will never meet.

  1. Would it be good for you do so?
  2. Should you do so?
  3. Are you a bad person if you don’t?
  4. Are all of the above really the same question?

Think carefully about your answer. It may be tempting to say “yes”. It feels righteous to say “yes”.

But in fact this is not hypothetical. It is the actual situation you are in.

This GiveWell article is entitled “Why is it so expensive to save a life?” but that’s incredibly weird, because the actual figure they give is astonishingly, mind-bogglingly, frankly disgustingly cheap: It costs about $4500 to save one human life. I don’t know how you can possibly find that expensive. I don’t understand how anyone can think, “Saving this person’s life might max out a credit card or two; boy, that sure seems expensive!

The standard for healthcare policy in the US is that something is worth doing if it is able to save one quality-adjusted life year for less than $50,000. That’s one year for ten times as much. Even accounting for the shorter lifespans and worse lives in poor countries, saving someone from a poor country for $4500 is at least one hundred times as cost-effective as that.

To put it another way, if you are a typical middle-class person in the First World, with an after-tax income of about $25,000 per year, and you were to donate 90% of that after-tax income to high-impact charities, you could be expected to save 5 lives every year. Over the course of a 30-year career, that’s 150 lives saved.

You would of course be utterly miserable for those 30 years, having given away all the money you could possibly have used for any kind of entertainment or enjoyment, not to mention living in the cheapest possible housing—maybe even a tent in a homeless camp—and eating the cheapest possible food. But you could do it, and you would in fact be expected to save over 100 lives by doing so.

So let me ask you again:

  1. Would it be good for you do so?
  2. Should you do so?
  3. Are you a bad person if you don’t?
  4. Are all of the above really the same question?

Peter Singer often writes as though the answer to all these questions is “yes”. But even he doesn’t actually live that way. He gives a great deal to charity, mind you; no one seems to know exactly how much, but estimates range from at least 10% to up to 50% of his income. My general impression is that he gives about 10% of his ordinary income and more like 50% of big prizes he receives (which are in fact quite numerous). Over the course of his life he has certainly donated at least a couple million dollars. Yet he clearly could give more than he does: He lives a comfortable, upper-middle-class life.

Peter Singer’s original argument for his view, from his essay “Famine, Affluence, and Morality”, is actually astonishingly weak. It involves imagining a scenario where a child is drowning in a lake and you could go save them, but only at the cost of ruining your expensive suit.

Obviously, you should save the child. We all agree on that. You are in fact a terrible person if you wouldn’t save the child.

But Singer tries to generalize this into a principle that requires us to donate all most of our income to international charities, and that just doesn’t follow.

First of all, that suit is not worth $4500. Not if you’re a middle-class person. That’s a damn Armani. No one who isn’t a millionaire wears suits like that.

Second, in the imagined scenario, you’re the only one who can help the kid. All I have to do is change that one thing and already the answer is different: If right next to you there is a trained, certified lifeguard, they should save the kid, not you. And if there are a hundred other people at the lake, and none of them is saving the kid… probably there’s a good reason for that? (It could be bystander effect, but actually that’s much weaker than a lot of people think.) The responsibility doesn’t uniquely fall upon you.

Third, the drowning child is a one-off, emergency scenario that almost certainly will never happen to you, and if it does ever happen, will almost certainly only happen once. But donation is something you could always do, and you could do over and over and over again, until you have depleted all your savings and run up massive debts.

Fourth, in the hypothetical scenario, there is only one child. What if there were ten—or a hundred—or a thousand? What if you couldn’t possibly save them all by yourself? Should you keep going out there and saving children until you become exhausted and you yourself drown? Even if there is a lifeguard and a hundred other bystanders right there doing nothing?

And finally, in the drowning child scenario, you are right there. This isn’t some faceless stranger thousands of miles away. You can actually see that child in front of you. Peter Singer thinks that doesn’t matter—actually his central point seems to be that it doesn’t matter. But I think it does.

Singer writes:

It makes no moral difference whether the person I can help is a neighbor’s child ten yards away from me or a Bengali whose name I shall never know, ten thousand miles away.

That’s clearly wrong, isn’t it? Relationships mean nothing? Community means nothing? There is no moral value whatsoever to helping people close to us rather than random strangers on the other side of the planet?

One answer might be to say that the answer to question 4 is “no”. You aren’t a bad person for not doing everything you should, and even though something would be good if you did it, that doesn’t necessarily mean you should do it.

Perhaps some things are above and beyond the call of duty: Good, perhaps even heroic, if you’re willing to do them, but not something we are all obliged to do. The formal term for this is supererogatory. While I think that overall utilitarianism is basically correct and has done great things for human society, one thing I think most utilitarians miss is that they seem to deny that supererogatory actions exist.

Even then, I’m not entirely sure it is good to be this altruistic.

Someone who really believed that we owe as much to random strangers as we do to our friends and family would never show up to any birthday parties, because any time spent at a birthday party would be more efficiently spent earning-to-give to some high-impact charity. They would never visit their family on Christmas, because plane tickets are expensive and airplanes burn a lot of carbon.

They also wouldn’t concern themselves with whether their job is satisfying or even not totally miserable; they would only care whether the total positive impact they can have on the world is positive, either directly through their work or by raising as much money as possible and donating it all to charity.

They would rest only the minimum amount they require to remain functional, eat only the barest minimum of nutritious food, and otherwise work, work, work, constantly, all the time. If their body was capable of doing the work, they would continue doing the work. For there is not a moment to waste when lives are on the line!

A world full of people like that would be horrible. We would all live our entire lives in miserable drudgery trying to maximize the amount we can donate to faceless strangers on the other side of the planet. There would be no joy or friendship in that world, only endless, endless toil.

When I bring this up in the Effective Altruism community, I’ve heard people try to argue otherwise, basically saying that we would never need everyone to devote themselves to the cause at this level, because we’d soon solve all the big problems and be able to go back to enjoying our lives. I think that’s probably true—but it also kind of misses the point.

Yes, if everyone gave their fair share, that fair share wouldn’t have to be terribly large. But we know for a fact that most people are not giving their fair share. So what now? What should we actually do? Do you really want to live in a world where the morally best people are miserable all the time sacrificing themselves at the altar of altruism?

Yes, clearly, most people don’t do enough. In fact, most people give basically nothing to high-impact charities. We should be trying to fix that. But if I am already giving far more than my fair share, far more than I would have to give if everyone else were pitching in as they should—isn’t there some point at which I’m allowed to stop? Do I have to give everything I can or else I’m a monster?

The conclusion that we ought to make ourselves utterly miserable in order to save distant strangers feels deeply unsettling. It feels even worse if we say that we ought to do so, and worse still if we feel we are bad people if we don’t.

One solution would be to say that we owe absolutely nothing to these distant strangers. Yet that clearly goes too far in the opposite direction. There are so many problems in this world that could be fixed if more people cared just a little bit about strangers on the other side of the planet. Poverty, hunger, war, climate change… if everyone in the world (or really even just everyone in power) cared even 1% as much about random strangers as they do about themselves, all these would be solved.

Should you donate to charity? Yes! You absolutely should. Please, I beseech you, give some reasonable amount to charity—perhaps 5% of your income, or if you can’t manage that, maybe 1%.

Should you make changes in your life to make the world better? Yes! Small ones. Eat less meat. Take public transit instead of driving. Recycle. Vote.

But I can’t ask you to give 90% of your income and spend your entire life trying to optimize your positive impact. Even if it worked, it would be utter madness, and the world would be terrible if all the good people tried to do that.

I feel quite strongly that this is the right approach: Give something. Your fair share, or perhaps even a bit more, because you know not everyone will.

Yet it’s surprisingly hard to come up with a moral theory on which this is the right answer.

It’s much easier to develop a theory on which we owe absolutely nothing: egoism, or any deontology on which charity is not an obligation. And of course Singer-style utilitarianism says that we owe virtually everything: As long as QALYs can be purchased cheaper by GiveWell than by spending on yourself, you should continue donating to GiveWell.

I think part of the problem is that we have developed all these moral theories as if we were isolated beings, who act in a world that is simply beyond our control. It’s much like the assumption of perfect competition in economics: I am but one producer among thousands, so whatever I do won’t affect the price.

But what we really needed was a moral theory that could work for a whole society. Something that would still make sense if everyone did it—or better yet, still make sense if half the people did it, or 10%, or 5%. The theory cannot depend upon the assumption that you are the only one following it. It cannot simply “hold constant” the rest of society.

I have come to realize that the Effective Altruism movement, while probably mostly good for the world as a whole, has actually been quite harmful to the mental health of many of its followers, including myself. It has made us feel guilty for not doing enough, pressured us to burn ourselves out working ever harder to save the world. Because we do not give our last dollar to charity, we are told that we are murderers.

But there are real murderers in this world. While you were beating yourself up over not donating enough, Vladmir Putin was continuing his invasion of Ukraine, ExxonMobil was expanding its offshore drilling, Daesh was carrying out hundreds of terrorist attacks, Qanon was deluding millions of people, and the human trafficking industry was making $150 billion per year.

In other words, by simply doing nothing you are considerably better than the real monsters responsible for most of the world’s horror.

In fact, those starving children in Africa that you’re sending money to help? They wouldn’t need it, were it not for centuries of colonial imperialism followed by a series of corrupt and/or incompetent governments ruled mainly by psychopaths.

Indeed the best way to save those people, in the long run, would be to fix their governments—as has been done in places like Namibia and Botswana. According to the World Development Indicators, the proportion of people living below the UN extreme poverty line (currently $2.15 per day at purchasing power parity) has fallen from 36% to 16% in Namibia since 2003, and from 42% to 15% in Botswana since 1984. Compare this to some countries that haven’t had good governments over that time: In Cote d’Ivoire the same poverty rate was 8% in 1985 but is 11% today (and was actually as high as 33% in 2015), while in Congo it remains at 35%. Then there are countries that are trying, but just started out so poor it’s a long way to go: Burkina Faso’s extreme poverty rate has fallen from 82% in 1994 to 30% today.

In other words, if you’re feeling bad about not giving enough, remember this: if everyone in the world were as good as you, you wouldn’t need to give a cent.

Of course, simply feeling good about yourself for not being a psychopath doesn’t accomplish very much either. Somehow we have to find a balance: Motivate people enough so that they do something, get them to do their share; but don’t pressure them to sacrifice themselves at the altar of altruism.

I think part of the problem here—and not just here—is that the people who most need to change are the ones least likely to listen. The kind of person who reads Peter Singer is already probably in the top 10% of most altruistic people, and really doesn’t need much more than a slight nudge to be doing their fair share. And meanwhile the really terrible people in the world have probably never picked up an ethics book in their lives, or if they have, they ignored everything it said.

I don’t quite know what to do about that. But I hope I can least convince you—and myself—to take some of the pressure off when it feels like we’re not doing enough.

Charity shouldn’t end at home

It so happens that this week’s post will go live on Christmas Day. I always try to do some kind of holiday-themed post around this time of year, because not only Christmas, but a dozen other holidays from various religions all fall around this time of year. The winter solstice seems to be a very popular time for holidays, and has been since antiquity: The Romans were celebrating Saturnalia 2000 years ago. Most of our ‘Christmas’ traditions are actually derived from Yuletide.

These holidays certainly mean many different things to different people, but charity and generosity are themes that are very common across a lot of them. Gift-giving has been part of the season since at least Saturnalia and remains as vital as ever today. Most of those gifts are given to our friends and loved ones, but a substantial fraction of people also give to strangers in the form of charitable donations: November and December have the highest rates of donation to charity in the US and the UK, with about 35-40% of people donating during this season. (Of course this is complicated by the fact that December 31 is often the day with the most donations, probably from people trying to finish out their tax year with a larger deduction.)

My goal today is to make you one of those donors. There is a common saying, often attributed to the Bible but not actually present in it: “Charity begins at home”.

Perhaps this is so. There’s certainly something questionable about the Effective Altruism strategy of “earning to give” if it involves abusing and exploiting the people around you in order to make more money that you then donate to worthy causes. Certainly we should be kind and compassionate to those around us, and it makes sense for us to prioritize those close to us over strangers we have never met. But while charity may begin at home, it must not end at home.

There are so many global problems that could benefit from additional donations. While global poverty has been rapidly declining in the early 21st century, this is largely because of the efforts of donors and nonprofit organizations. Official Development Assitance has been roughly constant since the 1970s at 0.3% of GNI among First World countries—well below international targets set decades ago. Total development aid is around $160 billion per year, while private donations from the United States alone are over $480 billion. Moreover, 9% of the world’s population still lives in extreme poverty, and this rate has actually slightly increased the last few years due to COVID.

There are plenty of other worthy causes you could give to aside from poverty eradication, from issues that have been with us since the dawn of human civilization (the Humane Society International for domestic animal welfare, the World Wildlife Federation for wildlife conservation) to exotic fat-tail sci-fi risks that are only emerging in our own lifetimes (the Machine Intelligence Research Institute for AI safety, the International Federation of Biosafety Associations for biosecurity, the Union of Concerned Scientists for climate change and nuclear safety). You could fight poverty directly through organizations like UNICEF or GiveDirectly, fight neglected diseases through the Schistomoniasis Control Initiative or the Against Malaria Foundation, or entrust an organization like GiveWell to optimize your donations for you, sending them where they think they are needed most. You could give to political causes supporting civil liberties (the American Civil Liberties Union) or protecting the rights of people of color (the North American Association of Colored People) or LGBT people (the Human Rights Campaign).

I could spent a lot of time and effort trying to figure out the optimal way to divide up your donations and give them to causes such as this—and then convincing you that it’s really the right one. (And there is even a time and place for that, because seemingly-small differences can matter a lot in this.) But instead I think I’m just going to ask you to pick something. Give something to an international charity with a good track record.

I think we worry far too much about what is the best way to give—especially people in the Effective Altruism community, of which I’m sort of a marginal member—when the biggest thing the world really needs right now is just more people giving more. It’s true, there are lots of worthless or even counter-productive charities out there: Please, please do not give to the Salvation Army. (And think twice before donating to your own church; if you want to support your own community, okay, go ahead. But if you want to make the world better, there are much better places to put your money.)

But above all, give something. Or if you already give, give more. Most people don’t give at all, and most people who give don’t give enough.

To a first approximation, all human behavior is social norms

Dec 15 JDN 2458833

The language we speak, the food we eat, and the clothes we wear—indeed, the fact that we wear clothes at all—are all the direct result of social norms. But norms run much deeper than this: Almost everything we do is more norm than not.

Why do sleep and wake up at a particular time of day? For most people, the answer is that they needed to get up to go to work. Why do you need to go to work at that specific time? Why does almost everyone go to work at the same time? Social norms.

Even the most extreme human behaviors are often most comprehensible in terms of social norms. The most effective predictive models of terrorism are based on social networks: You are much more likely to be a terrorist if you know people who are terrorists, and much more likely to become a terrorist if you spend a lot of time talking with terrorists. Cultists and conspiracy theorists seem utterly baffling if you imagine that humans form their beliefs rationally—and totally unsurprising if you realize that humans mainly form their beliefs by matching those around them.

For a long time, economists have ignored social norms at our peril; we’ve assumed that financial incentives will be sufficient to motivate behavior, when social incentives can very easily override them. Indeed, it is entirely possible for a financial incentive to have a negative effect, when it crowds out a social incentive: A good example is a friend who would gladly come over to help you with something as a friend, but then becomes reluctant if you offer to pay him $25. I previously discussed another example, where taking a mentor out to dinner sounds good but paying him seems corrupt.

Why do you drive on the right side of the road (or the left, if you’re in Britain)? The law? Well, the law is already a social norm. But in fact, it’s hardly just that. You probably sometimes speed or run red lights, which are also in violation of traffic laws. Yet somehow driving on the right side seem to be different. Well, that’s because driving on the right has a much stronger norm—and in this case, that norm is self-enforcing with the risk of severe bodily harm or death.

This is a good example of why it isn’t necessary for everyone to choose to follow a norm for that norm to have a great deal of power. As long as the norms include some mechanism for rewarding those who follow and punishing those who don’t, norms can become compelling even to those who would prefer not to obey. Sometimes it’s not even clear whether people are following a norm or following direct incentives, because the two are so closely aligned.

Humans are not the only social species, but we are by far the most social species. We form larger, more complex groups than any other animal; we form far more complex systems of social norms; and we follow those norms with slavish obedience. Indeed, I’m a little suspicious of some of the evolutionary models predicting the evolution of social norms, because they predict it too well; they seem to suggest that it should arise all the time, when in fact it’s only a handful of species who exhibit it at all and only we who build our whole existence around it.

Along with our extreme capacity for altruism, this is another way that human beings actually deviate more from the infinite identical psychopaths of neoclassical economics than most other animals. Yes, we’re smarter than other animals; other animals are more likely to make mistakes (though certainly we make plenty of our own). But most other animals aren’t motivated by entirely different goals than individual self-interest (or “evolutionary self-interest” in a Selfish Gene sort of sense) the way we typically are. Other animals try to be selfish and often fail; we try not to be selfish and usually succeed.

Economics experiments often go out of their way to exclude social motives as much as possible—anonymous random matching with no communication, for instance—and still end up failing. Human behavior in experiments is consistent, systematic—and almost never completely selfish.

Once you start looking for norms, you see them everywhere. Indeed, it becomes hard to see anything else. To a first approximation, all human behavior is social norms.

The evolution of human cooperation

Jun 17 JDN 2458287

If alien lifeforms were observing humans (assuming they didn’t turn out the same way—which they actually might, for reasons I’ll get to shortly), the thing that would probably baffle them the most about us is how we organize ourselves into groups. Each individual may be part of several groups at once, and some groups are closer-knit than others; but the most tightly-knit groups exhibit extremely high levels of cooperation, coordination, and self-sacrifice.

They might think at first that we are eusocial, like ants or bees; but upon closer study they would see that our groups are not very strongly correlated with genetic relatedness. We are somewhat more closely related to those in our groups than to those outsides, usually; but it’s a remarkably weak effect, especially compared to the extremely high relatedness of worker bees in a hive. No, to a first approximation, these groups are of unrelated humans; yet their level of cooperation is equal to if not greater than that exhibited by the worker bees.

However, the alien anthropologists would find that it is not that humans are simply predisposed toward extremely high altruism and cooperation in general; when two humans groups come into conflict, they are capable of the most extreme forms of violence imaginable. Human history is full of atrocities that combine the indifferent brutality of nature red in tooth and claw with the boundless ingenuity of a technologically advanced species. Yet except for a small proportion perpetrated by individual humans with some sort of mental pathology, these atrocities are invariably committed by one unified group against another. Even in genocide there is cooperation.

Humans are not entirely selfish. But nor are they paragons of universal altruism (though some of them aspire to be). Humans engage in a highly selective form of altruism—virtually boundless for the in-group, almost negligible for the out-group. Humans are tribal.

Being a human yourself, this probably doesn’t strike you as particularly strange. Indeed, I’ve mentioned it many times previously on this blog. But it is actually quite strange, from an evolutionary perspective; most organisms are not like this.

As I said earlier, there is actually reason to think that our alien anthropologist would come from a species with similar traits, simply because such cooperation may be necessary to achieve a full-scale technological civilization, let alone the capacity for interstellar travel. But there might be other possibilities; perhaps they come from a eusocial species, and their large-scale cooperation is within an extremely large hive.

It’s true that most organisms are not entirely selfish. There are various forms of cooperation within and even across species. But these usually involve only close kin, and otherwise involve highly stable arrangements of mutual benefit. There is nothing like the large-scale cooperation between anonymous unrelated individuals that is exhibited by all human societies.

How would such an unusual trait evolve? It must require a very particular set of circumstances, since it only seems to have evolved in a single species (or at most a handful of species, since other primates and cetaceans display some of the same characteristics).

Once evolved, this trait is clearly advantageous; indeed it turned a local apex predator into a species so successful that it can actually intentionally control the evolution of other species. Humans have become a hegemon over the entire global ecology, for better or for worse. Cooperation gave us a level of efficiency in producing the necessities of survival so great that at this point most of us spend our time working on completely different tasks. If you are not a farmer or a hunter or a carpenter (and frankly, even if you are a farmer with a tractor, a hunter with a rifle, or a carpenter with a table saw), you are doing work that would simply not have been possible without very large-scale human cooperation.

This extremely high fitness benefit only makes the matter more puzzling, however: If the benefits are so great, why don’t more species do this? There must be some other requirements that other species were unable to meet.

One clear requirement is high intelligence. As frustrating as it may be to be a human and watch other humans kill each other over foolish grievances, this is actually evidence of how smart humans are, biologically speaking. We might wish we were even smarter still—but most species don’t have the intelligence to make it even as far as we have.

But high intelligence is likely not sufficient. We can’t be sure of that, since we haven’t encountered any other species with equal intelligence; but what we do know is that even Homo sapiens didn’t coordinate on anything like our current scale for tens of thousands of years. We may have had tribal instincts, but if so they were largely confined to a very small scale. Something happened, about 50,000 years ago or so—not very long ago in evolutionary time—that allowed us to increase that scale dramatically.

Was this a genetic change? It’s difficult to say. There could have been some subtle genetic mutation, something that wouldn’t show up in the fossil record. But more recent expansions in human cooperation to the level of the nation-state and beyond clearly can’t be genetic; they were much too fast for that. They must be a form of cultural evolution: The replicators being spread are ideas and norms—memes—rather than genes.

So perhaps the very early shift toward tribal cooperation was also a cultural one. Perhaps it began not as a genetic mutation but as an idea—perhaps a metaphor of “universal brotherhood” as we often still hear today. The tribes that believed this ideas prospered; the tribes that didn’t were outcompeted or even directly destroyed.

This would explain why it had to be an intelligent species. We needed brains big enough to comprehend metaphors and generalize concepts. We needed enough social cognition to keep track of who was in the in-group and who was in the out-group.

If it was indeed a cultural shift, this should encourage us. (And since the most recent changes definitely were cultural, that is already quite encouraging.) We are not limited by our DNA to only care about a small group of close kin; we are capable of expanding our scale of unity and cooperation far beyond.
The real question is whether we can expand it to everyone. Unfortunately, there is some reason to think that this may not be possible. If our concept of tribal identity inherently requires both an in-group and an out-group, then we may never be able to include everyone. If we are only unified against an enemy, never simply for our own prosperity, world peace may forever remain a dream.

But I do have a work-around that I think is worth considering. Can we expand our concept of the out-group to include abstract concepts? With phrases like “The War on Poverty” and “The War on Terror”, it would seem in fact that we can. It feels awkward; it is somewhat imprecise—but then, so was the original metaphor of “universal brotherhood”. Our brains are flexible enough that they don’t actually seem to need the enemy to be a person; it can also be an idea. If this is right, then we can actually include everyone in our in-group, as long as we define the right abstract out-group. We can choose enemies like poverty, violence, cruelty, and despair instead of other nations or ethnic groups. If we must continue to fight a battle, let it be a battle against the pitiless indifference of the universe, rather than our fellow human beings.

Of course, the real challenge will be getting people to change their existing tribal identities. In the moment, these identities seem fundamentally intractable. But that can’t really be the case—for these identities have changed over historical time. Once-important categories have disappeared; new ones have arisen in their place. Someone in 4th century Constantinople would find the conflict between Democrats and Republicans as baffling as we would find the conflict between Trinitarians and Arians. The ongoing oppression of Native American people by White people would be unfathomable to someone of the 11th century Onondaga, who could scarcely imagine an enemy more different than the Seneca west of them. Even the conflict between Russia and NATO would probably seem strange to someone living in France in 1943, for whom Germany was the enemy and Russia was at least the enemy of the enemy—and many of those people are still alive.

I don’t know exactly how these tribal identities change (I’m working on it). It clearly isn’t as simple as convincing people with rational arguments. In fact, part of how it seems to work is that someone will shift their identity slowly enough that they can’t perceive the shift themselves. People rarely seem to appreciate, much less admit, how much their own minds have changed over time. So don’t ever expect to change someone’s identity in one sitting. Don’t even expect to do it in one year. But never forget that identities do change, even within an individual’s lifetime.

Reasonableness and public goods games

Apr 1 JDN 2458210

There’s a very common economics experiment called a public goods game, often used to study cooperation and altruistic behavior. I’m actually planning on running a variant of such an experiment for my second-year paper.

The game is quite simple, which is part of why it is used so frequently: You are placed into a group of people (usually about four), and given a little bit of money (say $10). Then you are offered a choice: You can keep the money, or you can donate some of it to a group fund. Money in the group fund will be multiplied by some factor (usually about two) and then redistributed evenly to everyone in the group. So for example if you donate $5, that will become $10, split four ways, so you’ll get back $2.50.

Donating more to the group will benefit everyone else, but at a cost to yourself. The game is usually set up so that the best outcome for everyone is if everyone donates the maximum amount, but the best outcome for you, holding everyone else’s choices constant, is to donate nothing and keep it all.

Yet it is a very robust finding that most people do neither of those things. There’s still a good deal of uncertainty surrounding what motivates people to donate what they do, but certain patterns that have emerged:

  1. Most people donate something, but hardly anyone donates everything.
  2. Increasing the multiplier tends to smoothly increase how much people donate.
  3. The number of people in the group isn’t very important, though very small groups (e.g. 2) behave differently from very large groups (e.g. 50).
  4. Letting people talk to each other tends to increase the rate of donations.
  5. Repetition of the game, or experience from previous games, tends to result in decreasing donation over time.
  6. Economists donate less than other people.

Number 6 is unfortunate, but easy to explain: Indoctrination into game theory and neoclassical economics has taught economists that selfish behavior is efficient and optimal, so they behave selfishly.

Number 3 is also fairly easy to explain: Very small groups allow opportunities for punishment and coordination that don’t exist in large groups. Think about how you would respond when faced with 2 defectors in a group of 4 as opposed to 10 defectors in a group of 50. You could punish the 2 by giving less next round; but punishing the 10 would end up punishing 40 others who had contributed like they were supposed to.

Number 4 is a very interesting finding. Game theory says that communication shouldn’t matter, because there is a unique Nash equilibrium: Donate nothing. All the promises in the world can’t change what is the optimal response in the game. But in fact, human beings don’t like to break their promises, and so when you get a bunch of people together and they all agree to donate, most of them will carry through on that agreement most of the time.

Number 5 is on the frontier of research right now. There are various theoretical accounts for why it might occur, but none of the models proposed so far have much predictive power.

But my focus today will be on findings 1 and 2.

If you’re not familiar with the underlying game theory, finding 2 may seem obvious to you: Well, of course if you increase the payoff for donating, people will donate more! It’s precisely that sense of obviousness which I am going to appeal to in a moment.

In fact, the game theory makes a very sharp prediction: For N players, if the multiplier is less than N, you should always contribute nothing. Only if the multiplier becomes larger than N should you donate—and at that point you should donate everything. The game theory prediction is not a smooth increase; it’s all-or-nothing. The only time game theory predicts intermediate amounts is on the knife-edge at exactly equal to N, where each player would be indifferent between donating and not donating.

But it feels reasonable that increasing the multiplier should increase donation, doesn’t it? It’s a “safer bet” in some sense to donate $1 if the payoff to everyone is $3 and the payoff to yourself is $0.75 than if the payoff to everyone is $1.04 and the payoff to yourself is $0.26. The cost-benefit analysis comes out better: In the former case, you can gain up to $2 if everyone donates, but would only lose $0.25 if you donate alone; but in the latter case, you would only gain $0.04 if everyone donates, and would lose $0.74 if you donate alone.

I think this notion of “reasonableness” is a deep principle that underlies a great deal of human thought. This is something that is sorely lacking from artificial intelligence: The same AI that tells you the precise width of the English Channel to the nearest foot may also tell you that the Earth is 14 feet in diameter, because the former was in its database and the latter wasn’t. Yes, WATSON may have won on Jeopardy, but it (he?) also made a nonsensical response to the Final Jeopardy question.

Human beings like to “sanity-check” our results against prior knowledge, making sure that everything fits together. And, of particular note for public goods games, human beings like to “hedge our bets”; we don’t like to over-commit to a single belief in the face of uncertainty.

I think this is what best explains findings 1 and 2. We don’t donate everything, because that requires committing totally to the belief that contributing is always better. We also don’t donate nothing, because that requires committing totally to the belief that contributing is always worse.

And of course we donate more as the payoffs to donating more increase; that also just seems reasonable. If something is better, you do more of it!

These choices could be modeled formally by assigning some sort of probability distribution over other’s choices, but in a rather unconventional way. We can’t simply assume that other people will randomly choose some decision and then optimize accordingly—that just gives you back the game theory prediction. We have to assume that our behavior and the behavior of others is in some sense correlated; if we decide to donate, we reason that others are more likely to donate as well.

Stated like that, this sounds irrational; some economists have taken to calling it “magical thinking”. Yet, as I always like to point out to such economists: On average, people who do that make more money in the games. Economists playing other economists always make very little money in these games, because they turn on each other immediately. So who is “irrational” now?

Indeed, if you ask people to predict how others will behave in these games, they generally do better than the game theory prediction: They say, correctly, that some people will give nothing, most will give something, and hardly any will give everything. The same “reasonableness” that they use to motivate their own decisions, they also accurately apply to forecasting the decisions of others.

Of course, to say that something is “reasonable” may be ultimately to say that it conforms to our heuristics well. To really have a theory, I need to specify exactly what those heuristics are.

“Don’t put all your eggs in one basket” seems to be one, but it’s probably not the only one that matters; my guess is that there are circumstances in which people would actually choose all-or-nothing, like if we said that the multiplier was 0.5 (so everyone giving to the group would make everyone worse off) or 10 (so that giving to the group makes you and everyone else way better off).

“Higher payoffs are better” is probably one as well, but precisely formulating that is actually surprisingly difficult. Higher payoffs for you? For the group? Conditional on what? Do you hold others’ behavior constant, or assume it is somehow affected by your own choices?

And of course, the theory wouldn’t be much good if it only worked on public goods games (though even that would be a substantial advance at this point). We want a theory that explains a broad class of human behavior; we can start with simple economics experiments, but ultimately we want to extend it to real-world choices.

How we can best help refugees

JDN 2457376

Though the debate seems to have simmered down a little over the past few weeks, the fact remains that we are in the middle of a global refugee crisis. There are 4 million refugees from Syria alone, part of 10 million refugees worldwide from various conflicts.

The ongoing occupation of the terrorist group / totalitarian state Daesh (also known as Islamic State, ISIS and ISIL, but like John Kerry, I like to use Daesh precisely because they seem to hate it) has displaced almost 14 million people, 3.3 million of them refugees from Syria.

Most of these refugees have fled to Lebanon, Jordan, Turkey, and, Iraq, for the obvious reason that these countries are both geographically closest and culturally best equipped to handle them.
There is another reason, however: Some of the other countries in the region, notably Saudi Arabia, have taken no refugees at all. In an upcoming post I intend to excoriate Saudi Arabia for a number of reasons, but this one is perhaps the most urgent. Their response? They simply deny it outright, claiming they’ve taken millions of refugees and somehow nobody noticed.

Turkey and Lebanon are stretched to capacity, however; they simply do not have the resources to take on more refugees. This gives the other nations of the world only two morally legitimate options:

1. We could take more refugees ourselves.

2. We could supply funding and support to Turkey and Lebanon for them to take on more refugees.

Most of the debate has centered around option (1), and in particular around Obama’s plan to take on about 10,000 refugees to the United States, which Ted Cruz calls “lunacy” (to be fair, if it takes one to know one…).

This debate has actually served more to indict the American population for paranoia and xenophobia than anything else. The fact that 17 US states—including some with Democrat governors—have unilaterally declared that they will not accept refugees (despite having absolutely no Constitutional authority to make such a declaration) is truly appalling.

Even if everything that the xenophobic bigots say were true—even if we really were opening ourselves to increased risk of terrorism and damaging our economy and subjecting ourselves to mass unemployment—we would still have a moral duty as human beings to help these people.

And of course almost all of it is false.

Only a tiny fraction of refugees are terrorists, indeed very likely smaller than the fraction of the native population or the fraction of those who arrive on legal visas, meaning that we would actually be diluting our risk of terrorism by accepting more refugees. And as you may recall from my post on 9/11, our risk of terrorism is already so small that the only thing we have to fear is fear itself.

There is a correlation between terrorism and refugees, but it’s almost entirely driven by the opposite effect: terrorism causes refugee crises.

The net aggregate economic effect of immigration is most likely positive. The effect on employment is more ambiguous; immigration does appear to create a small increase in unemployment in the short run as all those new people try to find jobs, and there is some evidence that it may reduce wages for local low-skill workers. But the employment effect is small temporary, and there is a long-run boost in overall productivity. However, it may not have much effect on overall growth: the positive correlation between immigration and economic growth is primarily due to the fact that higher growth triggers more immigration.

And of course, it’s important to keep in mind that the reason wages are depressed at all is that people come from places where wages are even lower, so they improve their standard of living, but may also reduce the standard of living of some of the workers who were already here. The paradigmatic example is immigrants who leave a wage of $4 per hour in Mexico, arrive in California, and end up reducing wages in California from $10 to $8. While this certainly hurts some people who went from $10 to $8, it’s so narrow-sighted as to border on racism to ignore the fact that it also raised other people from $4 to $8. The overall effect is not simply to redistribute wealth from some to others, but actually to create more wealth. If there are things we can do to prevent low-skill wages from falling, perhaps we should; but systematically excluding people who need work is not the way to do that.

Accepting 10,000 more refugees would have a net positive effect on the American economy—though given our huge population and GDP, probably a negligible one. It has been pointed out that Germany’s relatively open policy advances the interests of Germany as much as it does those of the refugees; but so what? They are doing the right thing, even if it’s not for entirely altruistic reasons. One of the central insights of economics is that the universe is nonzero-sum; helping someone else need not mean sacrificing your own interests, and when it doesn’t, the right thing to do should be a no-brainer. Instead of castigating Germany for doing what needs to be done for partially selfish reasons, we should be castigating everyone else for not even doing what’s in their own self-interest because they are so bigoted and xenophobic they’d rather harm themselves than help someone else. (Also, it does not appear to be in Angela Merkel’s self-interest to take more refugees; she is spending a lot of political capital to make this happen.)

We could follow Germany’s example, and Obama’s plan would move us in that direction.

But the fact remains that we could go through with Obama’s plan, indeed double, triple, quadruple it—and still not make a significant dent in the actual population of refugees who need help. When 1,500,000 people need help and the most powerful nation in the world offers to help 10,000, that isn’t an act of great openness and generosity; it’s almost literally the least we could do. 10,000 is only 0.7% of 1.5 million; even if we simply accepted an amount of refugees proportional to our own population it would be more like 70,000. If we instead accepted an amount of refugees proportional to our GDP we should be taking on closer to 400,000.

This is why in fact I think option (2) may be the better choice.

There actually are real cultural and linguistic barriers to assimilation for Syrian people in the United States, barriers which are much lower in Turkey and Lebanon. Immigrant populations always inevitably assimilate eventually, but there is a period of transition which is painful for both immigrants and locals, often lasting a decade or more. On top of this there is the simple logistical cost of moving all those people that far; crossing the border into Lebanon is difficult enough without having to raft across the Mediterranean, let alone being airlifted or shipped all the way across the Atlantic afterward. The fact that many refugees are willing to bear such a cost serves to emphasize their desperation; but it also suggests that there may be alternatives that would work out better for everyone.

The United States has a large population at 322 million; but Turkey (78 million) has about a quarter of our population and Jordan (8 million) and Lebanon (6 million) are about the size of our largest cities.

Our GDP, on the other hand, is vastly larger. At $18 trillion, we have 12 times the GDP of Turkey ($1.5 T), and there are individual American billionaires with wealth larger than the GDPs of Lebanon ($50 B) and Jordan ($31 B).

This means that while we have an absolute advantage in population, we have a comparative advantage in wealth—and the benefits of trade depend on comparative advantage. It therefore makes sense for us to in a sense “trade” wealth for population; in exchange for taking on fewer refugees, we would offer to pay a larger share of the expenses involved in housing, feeding, and ultimately assimilating those refugees.

Another thing we could offer (and have a comparative as well as absolute advantage in) is technology. These surprisingly-nice portable shelters designed by IKEA are an example of how First World countries can contribute to helping refugees without necessarily accepting them into their own borders (as well as an example of why #Scandinaviaisbetter). We could be sending equipment and technicians to provide electricity, Internet access, or even plumbing to the refugee camps. We could ship them staple foods or even MREs. (On the other hand, I am not impressed by the tech entrepreneurs whose “solutions” apparently involve selling more smartphone apps.)

The idea of actually taking on 400,000 or even 70,000 additional people into the United States is daunting even for those of us who strongly believe in helping the refugees—in the former case we’re adding another Cleveland, and even in the latter we’d be almost doubling Dearborn. But if we estimate the cost of simply providing money to support the refugee camps, the figures come out a lot less demanding.
Charities are currently providing money on the order of millions—which is to say on the order of single dollars per person. GBP 887,000 sounds like a lot of money until you realize it’s less than $0.50 per Syrian refugee.

Suppose we were to grant $5,000 per refugee per year. That’s surely more than enough. The UN is currently asking for $6.5 billion, which is only about $1,500 per refugee.

Yet to supply that much for all 4 million refugees would cost us only $20 billion per year, a mere 0.1% of our GDP. (Or if you like, a mere 3% of our military budget, which is probably smaller than what the increase would be if we stepped up our military response to Daesh.)

I say we put it to a vote among the American people: Are you willing to accept a flat 0.1% increase in income tax in order to help the refugees? (Would you even notice?) This might create an incentive to become a refugee when you’d otherwise have tried to stay in Syria, but is that necessarily a bad thing? Daesh, like any state, depends upon its tax base to function, so encouraging emigration undermines Daesh taxpayer by taxpayer. We could make it temporary and tied to the relief efforts—or, more radically, we could not do that, and use it as a starting point to build an international coalition for a global basic income.

Right now a global $5,000 per person per year would not be feasible (that would be almost half of the world’s GDP); but something like $1,000 would be, and would eliminate world hunger immediately and dramatically reduce global poverty. The US alone could in fact provide a $1,000 global basic income, though it would cost $7.2 trillion, which is over 40% of our $18.1 trillion GDP—not beyond our means, but definitely stretching them to the limit. Yet simply by including Europe ($18.5 T), China ($12.9 T), Japan ($4.2 T), India ($2.2 T), and Brazil ($1.8 T), we’d reduce the burden among the whole $57.7 trillion coalition to 12.5% of GDP. That’s roughly what we already spend on Medicare and Social Security. Not a small amount, to be sure; but this would get us within arm’s reach of permanently ending global poverty.

Think of the goodwill we’d gain around the world; think of how much it would undermine Daesh’s efforts to recruit followers if everyone knew that just across the border is a guaranteed paycheck from that same United States that Daesh keeps calling the enemy. This isn’t necessarily contradictory to a policy of accepting more refugees, but it would be something we could implement immediately, with minimal cost to ourselves.

And I’m sure there’d be people complaining that we were only doing it to make ourselves look good and stabilize the region economically, and it will all ultimately benefit us eventually—which is very likely true. But again, I say: So what? Would you rather we do the right thing and benefit from it, or do the wrong thing just so we dare not help ourselves?

Just give people money!

JDN 2457332 EDT 17:02.

Today is the Fifth of November, on which a bunch of people who liked a Hollywood movie start posting images in support of a fanatical religious terrorist in his plot to destroy democracy in the United Kingdom a few centuries ago. It’s really weird, but I’m not particularly interested in that.

Instead I’d like to talk about the solution to poverty, which we’ve known for a long time—in fact, it’s completely obvious—and yet have somehow failed to carry out. Many people doubt that it even works, not based on the empirical evidence, but because it just feels like it can’t be right, like it’s so obvious that surely it was tried and didn’t work and that’s why we moved on to other things. When you first tell a kindergartner that there are poor people in the world, that child will very likely ask: “Why don’t we just give them some money?”

Why not indeed?

Formally this is called a “direct cash transfer”, and it comes in many different variants, but basically they run along a continuum from unconditional—we just give it to everybody, no questions asked—to more and more conditional—you have to be below a certain income, or above a certain age, or have kids, or show up at our work program, or take a drug test, etc. The EU has a nice little fact sheet about the different types of cash transfer programs in use.

Actually, I’d argue that at the very far extreme is government salaries—the government will pay you $40,000 per year, provided that you teach high school every weekday. We don’t really think of that as a “conditional cash transfer” because it involves you providing a useful service (and is therefore more like an ordinary, private-sector salary), but many of the conditions imposed on cash transfers actually have this sort of character—we want people to do things that we think are useful to society, in order to justify us giving them the money. It really seems to be a continuum, from just giving money to everyone, to giving money to some people based on them doing certain things, to specifically hiring people to do something.

Social programs in different countries can be found at different places on this continuum. In the United States, our programs are extremely conditional, and also the total amount we give out is relatively small. In Europe, programs are not as conditional—though still conditional—and they give out more. And sure enough, after-tax poverty in Europe is considerably lower, even though before-tax poverty is about the same.

In fact, the most common way to make transfers conditional is to make them “in-kind”; instead of giving you money, we give you something—healthcare, housing, food. Sometimes this makes sense; actually I think for healthcare it makes the most sense, because price signals don’t work in a market as urgent and inelastic as healthcare (that is, you don’t shop around for an emergency room—in fact, people don’t even really shop around for a family doctor). But often it’s simply a condition we impose for political reasons; we don’t want those “lazy freeloaders” to do anything else with the money that we wouldn’t like, such as buying alcohol or gambling. Even poor people in India buy into this sort of reasoning. Nevermind that they generally don’t do that, or that they could just shift away spending they would otherwise be making (warning: technical economics paper within) to do those things anyway—it’s the principle of the thing.

Direct cash transfers not only work—they work about as well as the best things we’ve tried. Spending on cash transfers is about as cost-effective as spending on medical aid and malaria nets.

Other than in experiments (the largest of which I’m aware of was a town in Canada, unless you count Alaska’s Permanent Fund Dividend, which is unconditional but quite small), we have never really tried implementing a fully unconditional cash transfer system. “Too expensive” is usually the complaint, and it would indeed be relatively expensive (probably greater than all of what we currently spend on Social Security and Medicare, which are two of our biggest government budget items). Implementing a program with a cost on the order of $2 trillion per year is surely not something to be done lightly. But it would have one quite substantial benefit: It would eliminate poverty in the United States immediately and forever.

This is why I really like the “abolish poverty” movement; we must recognize that at our current level of economic development, poverty is no longer a natural state, a complex problem to solve. It is a policy decision that we are making. We are saying, as a society, that we would rather continue to have poverty than spend that $2 trillion per year, about 12% of our $17.4 trillion GDP. We are saying that we’d rather have people who are homeless and starving than lose 12 cents of every dollar we make. (To be fair, if we include the dynamic economic impact of this tax-and-transfer system it might actually turn out to be more than that; but it could in fact be less—the increased spending would boost the economy, just as the increased taxes would restrain it—and seems very unlikely to be more than 20% of GDP.)

For most of human history—and in most countries today—that is not the case. India could not abolish poverty immediately by a single tax policy; nor could China. Probably not Brazil either. Maybe Greece could do it, but then again maybe not. But Germany could; the United Kingdom could; France could; and we could in the United States. We have enough wealth now that with a moderate increase in government spending we could create an economic floor below which no person could fall. It is incumbent upon us at the very least to justify why we don’t.

I have heard it said that poverty is not a natural condition, but the result of human action. Even Nelson Mandela endorsed this view. This is false, actually. In general, poverty is the natural condition of all life forms on Earth (and probably all life forms in the universe). Natural selection evolves us toward fitting as many gene-packages into the environment as possible, not toward maximizing the happiness of the sentient beings those gene-packages may happen to be. To a first approximation, all life forms suffer in poverty.

We live at a unique time in human history; for no more than the last century—and perhaps not even that—we have actually had so much wealth that we could eliminate poverty by choice. For hundreds of thousands of years human beings toiled in poverty because there was no such choice. Perhaps good policy in Greece could end poverty today, but it couldn’t have during the reign of Pericles. Good policy in Italy could end poverty now, but not when Caesar was emperor. Good policy in the United Kingdom could easily end poverty immediately, but even under Queen Victoria that wasn’t feasible.

Maybe that’s why we aren’t doing it? Our cultural memory was forged in a time decades or centuries ago, before we had this much wealth to work with. We speak of “end world hunger” in the same breath as “cure cancer” or “conquer death”, a great dream that has always been impossible and perhaps still is—but in fact we should speak of it in the same breath as “split the atom” and “land on the Moon”, seminal achievements that our civilization is now capable of thanks to economic and technological revolution.

Capitalism also seems to have a certain momentum to it; once you implement a market economy that maximizes wealth by harnessing self-interest, people seem to forget that we are fundamentally altruistic beings. I may never forget that economist who sent me an email with “altruism” in scare quotes, as though it was foolish (or at best imprecise) to say that human beings care about one another. But in fact we are the most altruistic species on Earth, without question, in a sense so formal and scientific it can literally be measured quantitatively.

There are real advantages to harnessing self-interest—not least, I know my own interests considerably better than I know yours, no matter who you are—and that is part of how we have achieved this great level of wealth (though personally I think science, democracy, and the empowerment of women are the far greater causes of our prosperity). But we must not let it forget us why we wanted to have wealth in the first place: Not to concentrate power in a handful of individuals who will pass it on to their heirs; not to “maximize work incentives”; not to give us the fanciest technological gadgets. The reason we wanted to have wealth was so that we could finally free ourselves from the endless toil that was our lot by birth and that of all other beings—to let us finally live, instead of merely survive. There is a peak to Maslow’s pyramid, and we could stand there now, together; but we must find the will to give up that 12 cents of every dollar.
