In last week’s post I made a sharp distinction between believing in human progress and believing that colonialism was justified. To make this argument, I relied upon a moral assumption that seems to me perfectly obvious, and probably would to most ethicists as well: Moral responsibility does not inherit across generations, and people are only responsible for their individual actions.

But is in fact this principle is not uncontroversial in many circles. When I read utterly nonsensical arguments like this one from the aptly-named Race Baitr saying that White people have no role to play in the liberation of Black people apparently because our blood is somehow tainted by the crimes our ancestors, it becomes apparent to me that this principle is not obvious to everyone, and therefore is worth defending. Indeed, many applications of the concept of “White Privilege” seem to ignore this principle, speaking as though racism is not something one does or participates in, but something that one is simply by being born with less melanin. Here’s a Salon interview specifically rejecting the proposition that racism is something one does:

For white people, their identities rest on the idea of racism as about good or bad people, about moral or immoral singular acts, and if we’re good, moral people we can’t be racist – we don’t engage in those acts. This is one of the most effective adaptations of racism over time—that we can think of racism as only something that individuals either are or are not “doing.”

If racism isn’t something one does, then what in the world is it? It’s all well and good to talk about systems and social institutions, but ultimately systems and social institutions are made of human behaviors. If you think most White people aren’t doing enough to combat racism (which sounds about right to me!), say that—don’t make some bizarre accusation that simply by existing we are inherently racist. (Also: We? I’m only 75% White, so am I only 75% inherently racist?) And please, stop redefining the word “racism” to mean something other than what everyone uses it to mean; “White people are snakes” is in fact a racist sentiment (and yes, one I’ve actually heard–indeed, here is the late Muhammad Ali comparing all White people to rattlesnakes, and Huffington Post fawning over him for it).

Racism is clearly more common and typically worse when performed by White people against Black people—but contrary to the claims of some social justice activists the White perpetrator and Black victim are not part of the definition of racism. Similarly, sexism is more common and more severe committed by men against women, but that doesn’t mean that “men are pigs” is not a sexist statement (and don’t tell me you haven’t heard that one). I don’t have a good word for bigotry by gay people against straight people (“heterophobia”?) but it clearly does happen on occasion, and similarly cannot be defined out of existence.

I wouldn’t care so much that you make this distinction between “racism” and “racial prejudice”, except that it’s not the normal usage of the word “racism” and therefore confuses people, and also this redefinition clearly is meant to serve a political purpose that is quite insidious, namely making excuses for the most extreme and hateful prejudice as long as it’s committed by people of the appropriate color. If “White people are snakes” is not racism, then the word has no meaning.

Not all discussions of “White Privilege” are like this, of course; this article from Occupy Wall Street actually does a fairly good job of making “White Privilege” into a sensible concept, albeit still not a terribly useful one in my opinion. I think the useful concept is oppression—the problem here is not how we are treating White people, but how we are treating everyone else. “What privilege gives you is the freedom to be who you are.”? Shouldn’t everyone have that?

Almost all the so-called “benefits” or “perks” associated with “privilege” are actually forgone harms—they are not good things done to you, but bad things not done to you. “But benefitting from racist systems doesn’t mean that everything is magically easy for us. It just means that as hard as things are, they could always be worse.” No, that is not what the word “benefit” means. The word “benefit” means you would be worse off without it—and in most cases that simply isn’t true. Many White people obviously think that it is true—which is probably a big reason why so many White people fight so hard to defend racism, you know; you’ve convinced them it is in their self-interest. But, with rare exceptions, it is not; most racial discrimination has literally zero long-run benefit. It’s just bad. Maybe if we helped people appreciate that more, they would be less resistant to fighting racism!

The only features of “privilege” that really make sense as benefits are those that occur in a state of competition—like being more likely to be hired for a job or get a loan—but one of the most important insights of economics is that competition is nonzero-sum, and fairer competition ultimately means a more efficient economy and thus more prosperity for everyone.

But okay, let’s set that aside and talk about this core question of what sort of responsibility we bear for the acts of our ancestors. Many White people clearly do feel deep shame about what their ancestors (or people the same color as their ancestors!) did hundreds of years ago. The psychological reactance to that shame may actually be what makes so many White people deny that racism even exists (or exists anymore)—though a majority of Americans of all races do believe that racism is still widespread.

We also apply some sense of moral responsibility applied to whole races quite frequently. We speak of a policy “benefiting White people” or “harming Black people” and quickly elide the distinction between harming specific people who are Black, and somehow harming “Black people” as a group. The former happens all the time—the latter is utterly nonsensical. Similarly, we speak of a “debt owed by White people to Black people” (which might actually make sense in the very narrow sense of economic reparations, because people do inherit money! They probably shouldn’t, that is literally feudalist, but in the existing system they in fact do), which makes about as much sense as a debt owed by tall people to short people. As Walter Michaels pointed out in The Trouble with Diversity (which I highly recommend), because of this bizarre sense of responsibility we are often in the habit of “apologizing for something you didn’t do to people to whom you didn’t do it (indeed to whom it wasn’t done)”. It is my responsibility to condemn colonialism (which I indeed do), to fight to ensure that it never happens again; it is not my responsibility to apologize for colonialism.

This makes some sense in evolutionary terms; it’s part of the all-encompassing tribal paradigm, wherein human beings come to identify themselves with groups and treat those groups as the meaningful moral agents. It’s much easier to maintain the cohesion of a tribe against the slings and arrows (sometimes quite literal) of outrageous fortune if everyone believes that the tribe is one moral agent worthy of ultimate concern.

This concept of racial responsibility is clearly deeply ingrained in human minds, for it appears in some of our oldest texts, including the Bible: “You shall not bow down to them or worship them; for I, the Lord your God, am a jealous God, punishing the children for the sin of the parents to the third and fourth generation of those who hate me,” (Exodus 20:5)

Why is inheritance of moral responsibility across generations nonsensical? Any number of reasons, take your pick. The economist in me leaps to “Ancestry cannot be incentivized.” There’s no point in holding people responsible for things they can’t control, because in doing so you will not in any way alter behavior. The Stanford Encyclopedia of Philosophy article on moral responsibility takes it as so obvious that people are only responsible for actions they themselves did that they don’t even bother to mention it as an assumption. (Their big question is how to reconcile moral responsibility with determinism, which turns out to be not all that difficult.)

An interesting counter-argument might be that descent can be incentivized: You could use rewards and punishments applied to future generations to motivate current actions. But this is actually one of the ways that incentives clearly depart from moral responsibilities; you could incentivize me to do something by threatening to murder 1,000 children in China if I don’t, but even if it was in fact something I ought to do, it wouldn’t be those children’s fault if I didn’t do it. They wouldn’t deserve punishment for my inaction—I might, and you certainly would for using such a cruel incentive.

Moreover, there’s a problem with dynamic consistency here: Once the action is already done, what’s the sense in carrying out the punishment? This is why a moral theory of punishment can’t merely be based on deterrence—the fact that you could deter a bad action by some other less-bad action doesn’t make the less-bad action necessarily a deserved punishment, particularly if it is applied to someone who wasn’t responsible for the action you sought to deter. In any case, people aren’t thinking that we should threaten to punish future generations if people are racist today; they are feeling guilty that their ancestors were racist generations ago. That doesn’t make any sense even on this deterrence theory.

There’s another problem with trying to inherit moral responsibility: People have lots of ancestors. Some of my ancestors were most likely rapists and murderers; most were ordinary folk; a few may have been great heroes—and this is true of just about anyone anywhere. We all have bad ancestors, great ancestors, and, mostly, pretty good ancestors. 75% of my ancestors are European, but 25% are Native American; so if I am to apologize for colonialism, should I be apologizing to myself? (Only 75%, perhaps?) If you go back enough generations, literally everyone is related—and you may only have to go back about 4,000 years. That’s historical time.

Of course, we wouldn’t be different colors in the first place if there weren’t some differences in ancestry, but there is a huge amount of gene flow between different human populations. The US is a particularly mixed place; because most Black Americans are quite genetically mixed, it is about as likely that any randomly-selected Black person in the US is descended from a slaveowner as it is that any randomly-selected White person is. (Especially since there were a large number of Black slaveowners in Africa and even some in the United States.) What moral significance does this have? Basically none! That’s the whole point; your ancestors don’t define who you are.

If these facts do have any moral significance, it is to undermine the sense most people seem to have that there are well-defined groups called “races” that exist in reality, to which culture responds. No; races were created by culture. I’ve said this before, but it bears repeating: The “races” we hold most dear in the US, White and Black, are in fact the most nonsensical. “Asian” and “Native American” at least almost make sense as categories, though Chippewa are more closely related to Ainu than Ainu are to Papuans. “Latino” isn’t utterly incoherent, though it includes as much Aztec as it does Iberian. But “White” is a club one can join or be kicked out of, while “Black” is the majority of genetic diversity.

Sex is a real thing—while there are intermediate cases of course, broadly speaking humans, like most metazoa, are sexually dimorphic and come in “male” and “female” varieties. So sexism took a real phenomenon and applied cultural dynamics to it; but that’s not what happened with racism. Insofar as there was a real phenomenon, it was extremely superficial—quite literally skin deep. In that respect, race is more like class—a categorization that is itself the result of social institutions.

To be clear: Does the fact that we don’t inherit moral responsibility from our ancestors absolve us from doing anything to rectify the inequities of racism? Absolutely not. Not only is there plenty of present discrimination going on we should be fighting, there are also inherited inequities due to the way that assets and skills are passed on from one generation to the next. If my grandfather stole a painting from your grandfather and both our grandfathers are dead but I am now hanging that painting in my den, I don’t owe you an apology—but I damn well owe you a painting.

The further we become from the past discrimination the harder it gets to make reparations, but all hope is not lost; we still have the option of trying to reset everyone’s status to the same at birth and maintaining equality of opportunity from there. Of course we’ll never achieve total equality of opportunity—but we can get much closer than we presently are.

We could start by establishing an extremely high estate tax—on the order of 99%—because no one has a right to be born rich. Free public education is another good way of equalizing the distribution of “human capital” that would otherwise be concentrated in particular families, and expanding it to higher education would make it that much better. It even makes sense, at least in the short run, to establish some affirmative action policies that are race-conscious and sex-conscious, because there are so many biases in the opposite direction that sometimes you must fight bias with bias.

Actually what I think we should do in hiring, for example, is assemble a pool of applicants based on demographic quotas to ensure a representative sample, and then anonymize the applications and assess them on merit. This way we do ensure representation and reduce bias, but don’t ever end up hiring anyone other than the most qualified candidate. But nowhere should we think that this is something that White men “owe” to women or Black people; it’s something that people should do in order to correct the biases that otherwise exist in our society. Similarly with regard to sexism: Women exhibit just as much unconscious bias against other women as men do. This is not “men” hurting “women”—this is a set of unconscious biases found in almost everywhere and social structures almost everywhere that systematically discriminate against people because they are women.

Perhaps by understanding that this is not about which “team” you’re on (which tribe you’re in), but what policy we should have, we can finally make these biases disappear, or at least fade so small that they are negligible.

The irrationality of racism

I thought about making today’s post about the crazy currency crisis in Switzerland, but currency exchange rates aren’t really my area of expertise; this is much more in Krugman’s bailiwick, so you should probably read what Krugman says about the situation. There is one thing I’d like to say, however: I think there is a really easy way to create credible inflation and boost aggregate demand, but for some reason nobody is ever willing to do it: Give people money. Emphasis here on the people—not banks. Don’t adjust interest rates or currency pegs, don’t engage in quantitative easing. Give people money. Actually write a bunch of checks, presumably in the form of refundable tax rebates.

The only reason I can think of that economists don’t do this is they are afraid of helping poor people. They wouldn’t put it that way; maybe they’d say they want to avoid “moral hazard” or “perverse incentives”. But those fears didn’t stop them from loaning $2 trillion to banks or adding $4 trillion to the monetary base; they didn’t stop them from fighting for continued financial deregulation when what the world economy most desperately needs is stronger financial regulation. Our whole derivatives market practically oozes moral hazard and perverse incentives, but they aren’t willing to shut down that quadrillion-dollar con game. So that can’t be the actual fear. No, it has to be a fear of helping poor people instead of rich people, as though “capitalism” meant a system in which we squeeze the poor as tight as we can and heap all possible advantages upon those who are already wealthy. No, that’s called feudalism. Capitalism is supposed to be a system where markets are structured to provide free and fair competition, with everyone on a level playing field.

A basic income is a fundamentally capitalist policy, which maintains equal opportunity with a minimum of government intervention and allows the market to flourish. I suppose if you want to say that all taxation and government spending is “socialist”, fine; then every nation that has ever maintained stability for more than a decade has been in this sense “socialist”. Every soldier, firefighter and police officer paid by a government payroll is now part of a “socialist” system. Okay, as long as we’re consistent about that; but now you really can’t say that socialism is harmful; on the contrary, on this definition socialism is necessary for capitalism. In order to maintain security of property, enforcement of contracts, and equality of opportunity, you need government. Maybe we should just give up on the words entirely, and speak more clearly about what specific policies we want. If I don’t get to say that a basic income is “capitalist”, you don’t get to say financial deregulation is “capitalist”. Better yet, how about you can’t even call it “deregulation”? You have to actually argue in front of a crowd of people that it should be legal for banks to lie to them, and there should be no serious repercussions for any bank that cheats, steals, colludes, or even launders money for terrorists. That is, after all, what financial deregulation actually does in the real world.

Okay, that’s enough about that.

My birthday is coming up this Monday; thus completes my 27th revolution around the Sun. With birthdays come thoughts of ancestry: Though I appear White, I am legally one-quarter Native American, and my total ethnic mix includes English, German, Irish, Mohawk, and Chippewa.

Biologically, what exactly does that mean? Next to nothing.

Human genetic diversity is a real thing, and there are genetic links to not only dozens of genetic diseases and propensity toward certain types of cancer, but also personality and intelligence. There are also of course genes for skin pigmentation.

The human population does exhibit some genetic clustering, but the categories are not what you’re probably used to: Good examples of relatively well-defined genetic clusters include Ashkenazi, Papuan, and Mbuti. There are also many different haplogroups, such as mitochondrial haplogroups L3 and CZ.

Maybe you could even make a case for the “races” East Asian, South Asian, Pacific Islander, and Native American, since the indigenous populations of these geographic areas largely do come from the same genetic clusters. Or you could make a bigger category and call them all “Asian”—but if you include Papuan and Aborigine in “Asian” you’d pretty much have to include Chippewa and Najavo as well.

But I think it tells you a lot about what “race” really means when you realize that the two “race” categories which are most salient to Americans are in fact the categories that are genetically most meaningless. “White” and “Black” are totally nonsensical genetic categorizations.

Let’s start with “Black”; defining a “Black” race is like defining a category of animals by the fact that they are all tinted red—foxes yes, dogs no; robins yes, swallows no; ladybirds yes, cockroaches no. There is more genetic diversity within Africa than there is outside of it. There are African populations that are more closely related to European populations than they are to other African populations. The only thing “Black” people have in common is that their skin is dark, which is due to convergent evolution: It’s not due to common ancestry, but a common environment. Dark skin has a direct survival benefit in climates with intense sunlight.  The similarity is literally skin deep.

What about “White”? Well, there are some fairly well-defined European genetic populations, so if we clustered those together we might be able to get something worth calling “White”. The problem is, that’s not how it happened. “White” is a club. The definition of who gets to be “White” has expanded over time, and even occasionally contracted. Originally Hebrew, Celtic, Hispanic, and Italian were not included (and Hebrew, for once, is actually a fairly sensible genetic category, as long as you restrict it to Ashkenazi), but then later they were. But now that we’ve got a lot of poor people coming in from Mexico, we don’t quite think of Hispanics as “White” anymore. We actually watched Arabs lose their “White” card in real-time in 2001; before 9/11, they were “White”; now, “Arab” is a separate thing. And “Muslim” is even treated like a race now, which is like making a racial category of “Keynesians”—never forget that Islam is above all a belief system.

Actually, “White privilege” is almost a tautology—the privilege isn’t given to people who were already defined as “White”, the privilege is to be called “White”. The privilege is to have your ancestors counted in the “White” category so that they can be given rights, while people who are not in the category are denied those rights. There does seem to be a certain degree of restriction by appearance—to my knowledge, no population with skin as dark as Kenyans has ever been considered “White”, and Anglo-Saxons and Nordics have always been included—but the category is flexible to political and social changes.

But really I hate that word “privilege”, because it gets the whole situation backwards. When you talk about “White privilege”, you make it sound as though the problem with racism is that it gives unfair advantages to White people (or to people arbitrarily defined as “White”). No, the problem is that people who are not White are denied rights. It isn’t what White people have that’s wrong; it’s what Black people don’t have. Equating those two things creates a vision of the world as zero-sum, in which each gain for me is a loss for you.

Here’s the thing about zero-sum games: All outcomes are Pareto-efficient. Remember when I talked about Pareto-efficiency? As a quick refresher, an outcome is Pareto-efficient if there is no way for one person to be made better off without making someone else worse off. In general, it’s pretty hard to disagree that, other things equal, Pareto-efficiency is a good thing, and Pareto-inefficiency is a bad thing. But if racism were about “White privilege” and the game were zero-sum, racism would have to be Pareto-efficient.

In fact, racism is Pareto-inefficient, and that is part of why it is so obviously bad. It harms literally billions of people, and benefits basically no one. Maybe there are a few individuals who are actually, all things considered, better off than they would have been if racism had not existed. But there are certainly not very many such people, and in fact I’m not sure there are any at all. If there are any, it would mean that technically racism is not Pareto-inefficient—but it is definitely very close. At the very least, the damage caused by racism is several orders of magnitude larger than any benefits incurred.

That’s why the “privilege” language, while well-intentioned, is so insidious; it tells White people that racism means taking things away from them. Many of these people are already in dire straits—broke, unemployed, or even homeless—so taking away what they have sounds particularly awful. Of course they’d be hostile to or at least dubious of attempts to reduce racism. You just told them that racism is the only thing keeping them afloat! In fact, quite the opposite is the case: Poor White people are, second only to poor Black people, those who stand the most to gain from a more just society. David Koch and Donald Trump should be worried; we will probably have to take most of their money away in order to achieve social justice. (Bill Gates knows we’ll have to take most of his money away, but he’s okay with that; in fact he may end up giving it away before we get around to taking it.) But the average White person will almost certainly be better off than they were.

Why does it seem like there are benefits to racism? Again, because people are accustomed to thinking of the world as zero-sum. One person is denied a benefit, so that benefit must go somewhere else right? Nope—it can just disappear entirely, and in this case typically does.

When a Black person is denied a job in favor of a White person who is less qualified, doesn’t that White person benefit? Uh, no, actually, not really. They have been hired for a job that isn’t an optimal fit for them; they aren’t working to their comparative advantage, and that Black person isn’t either and may not be working at all. The total output of the economy will be thereby reduced slightly. When this happens millions of times, the total reduction in output can be quite substantial, and as a result that White person was hired at $30,000 for an unsuitable job when in a racism-free world they’d have been hired at $40,000 for a suitable one. A similar argument holds for sexism; men don’t benefit from getting jobs women are denied if one of those women would have invented a cure for prostate cancer.

Indeed, the empowerment of women and minorities is kind of the secret cheat code for creating a First World economy. The great successes of economic development—Korea, Japan, China, the US in WW2—had their successes precisely at a time when they suddenly started including women in manufacturing, effectively doubling their total labor capacity. Moreover, it’s pretty clear that the causation ran in this direction. Periods of economic growth are associated with increases in solidarity with other groups—and downturns with decreased solidarity—but the increase in women in the workforce was sudden and early while the increase in growth and total output was prolonged.

Racism is irrational. Indeed it is so obviously irrational that for decades now neoclassical economists have been insisting that there is no need for civil rights policy, affirmative action, etc. because the market will automatically eliminate racism by the rational profit motive. A more recent literature has attempted to show that, contrary to all appearances, racism actually is rational in some cases. Inevitably it relies upon either the background of a racist society (maybe Black people are, on average, genuinely less qualified, but it would only be because they’ve been given poorer opportunities), or an assumption of “discriminatory tastes”, which is basically giving up and redefining the utility function so that people simply get direct pleasure from being racists. Of course, on that sort of definition, you can basically justify any behavior as “rational”: Maybe he just enjoys banging his head against the wall! (A similar slipperiness is used by egoists to argue that caring for your children is actually “selfish”; well, it makes you happy, doesn’t it? Yes, but that’s not why we do it.)

There’s a much simpler way to understand this situation: Racism is irrational, and so is human behavior.

That isn’t a complete explanation, of course; and I think one major misunderstanding neoclassical economists have of cognitive economists is that they think this is what we do—we point out that something is irrational, and then high-five and go home. No, that’s not what we do. Finding the irrationality is just the start; next comes explaining the irrationality, understanding the irrationality, and finally—we haven’t reached this point in most cases—fixing the irrationality.

So what explains racism? In short, the tribal paradigm. Human beings evolved in an environment in which the most important factor in our survival and that of our offspring was not food supply or temperature or predators, it was tribal cohesion. With a cohesive tribe, we could find food, make clothes, fight off lions. Without one, we were helpless. Millions of years in this condition shaped our brains, programming them to treat threats to tribal cohesion as the greatest possible concern. We even reached the point where solidarity for the tribe actually began to dominate basic survival instincts: For a suicide bomber the unity of the tribe—be it Marxism for the Tamil Tigers or Islam for Al-Qaeda—is more important than his own life. We will do literally anything if we believe it is necessary to defend the identities we believe in.

And no, we rationalists are no exception here. We are indeed different from other groups; the beliefs that define us, unlike the beliefs of literally every other group that has ever existed, are actually rationally founded. The scientific method really isn’t just another religion, for unlike religion it actually works. But still, if push came to shove and we were forced to kill and die in order to defend rationality, we would; and maybe we’d even be right to do so. Maybe the French Revolution was, all things considered, a good thing—but it sure as hell wasn’t nonviolent.

This is the background we need to understand racism. It actually isn’t enough to show people that racism is harmful and irrational, because they are programmed not to care. As long as racial identification is the salient identity, the tribe by which we define ourselves, we will do anything to defend the cohesion of that tribe. It is not enough to show that racism is bad; we must in fact show that race doesn’t matter. Fortunately, this is easy, for as I explained above, race does not actually exist.

That makes racism in some sense easier to deal with than sexism, because the very categories of races upon which it is based are fundamentally faulty. Sexes, on the other hand, are definitely a real thing. Males and females actually are genetically different in important ways. Exactly how different in what ways is an open question, and what we do know is that for most of the really important traits like intelligence and personality the overlap outstrips the difference. (The really big, categorical differences all appear to be physical: Anatomy, size, testosterone.) But conquering sexism may always be a difficult balance, for there are certain differences we won’t be able to eliminate without altering DNA. That no more justifies sexism than the fact that height is partly genetic would justify denying rights to short people (which, actually, is something we do); but it does make matters complicated, because it’s difficult to know whether an observed difference (for instance, most pediatricians are female, while most neurosurgeons are male) is due to discrimination or innate differences.

Racism, on the other hand, is actually quite simple: Almost any statistically significant difference in behavior or outcome between races must be due to some form of discrimination somewhere down the line. Maybe it’s not discrimination right here, right now; maybe it’s discrimination years ago that denied opportunities, or discrimination against their ancestors that led them to inherit less generations later; but it almost has to be discrimination against someone somewhere, because it is only by social construction that races exist in the first place. I do say “almost” because I can think of a few exceptions: Black people are genuinely less likely to use tanning salons and genuinely more likely to need vitamin D supplements, but both of those things are directly due to skin pigmentation. They are also more likely to suffer from sickle-cell anemia, which is another convergent trait that evolved in tropical climates as a response to malaria. But unless you can think of a reason why employment outcomes would depend upon vitamin D, the huge difference in employment between Whites and Blacks really can’t be due to anything but discrimination.

I imagine most of my readers are more sophisticated than this, but just in case you’re wondering about the difference in IQ scores between Whites and Blacks, that is indeed a real observation, but IQ isn’t entirely genetic. The reason IQ scores are rising worldwide (the Flynn Effect) is due to improvements in environmental conditions: Fewer environmental pollutants—particularly lead and mercury, the removal of which is responsible for most of the reduction in crime in America over the last 20 years—better nutrition, better education, less stress. Being stupid does not make you poor (or how would we explain Donald Trump?), but being poor absolutely does make you stupid. Combine that with the challenges and inconsistencies in cross-national IQ comparisons, and it’s pretty clear that the higher IQ scores in rich nations are an effect, not a cause, of their affluence. Likewise, the lower IQ scores of Black people in the US are entirely explained by their poorer living conditions, with no need for any genetic hypothesis—which would also be very difficult in the first place precisely because “Black” is such a weird genetic category.

Unfortunately, I don’t yet know exactly what it takes to change people’s concept of group identification. Obviously it can be done, for group identities change all the time, sometimes quite rapidly; but we simply don’t have good research on what causes those changes or how they might be affected by policy. That’s actually a major part of the experiment I’ve been trying to get funding to run since 2009, which I hope can now become my PhD thesis. All I can say is this: I’m working on it.
