Rawlsian Locational Choice (a highly abstract open borders metric)

Leave a comment

I’ve been thinking more about how the openness of the world’s borders might be quantified (see here for the beginning of this topic). In that post, I suggested several criteria– right to invite, welcoming to sojourners, family values, social integration, refuge, opportunity, and civil rights– which might be evaluated separately, and then compiled into a single “index” value that purports to measure the openness of a country’s borders. The categories listed are not readily measurable, of course. Is a country “welcoming to sojourners?” Well, what kind of sojourners? What if Country A welcomes most aspiring sojourners, because mostly high-skilled sojourners happen to be interested in coming to it, while Country B rejects most aspiring sojourners because the only people who want to come are low-skill, angry young men from a country which is historically an enemy? Does it make a difference if Country B would be delighted to accept the kind of sojourners that go to Country A? Questions of this kind can be asked about all of the items in the list.

In general, there is an important distinction between rules and results. There are huge differences in demand for immigration to different countries. Generally, the United States and the Anglosphere, and probably to a slightly lesser extent Western Europe, are attractive destinations for migrants, while there are probably few who aspire to migrate to the world’s many impoverished and/or unfree countries. Simply to calculate the foreign-born share of the population would thus be a very mistaken way to measure and compare the openness of borders, because the countries with the highest foreign-born population shares are often the hardest to get into. Foreign-born share of population is a measure of results. An openness index should in principle measure rules. But rules are not inherently quantitative. Suppose a country only lets in people with a college education or more. That’s a rule. There’s no number there.

The following is an attempt to think clearly about how the openness of borders might be measured. It isn’t a practical program of data collection, and how to implement a data collection program that would achieve it, even approximately, is a further problem of some difficulty. It’s more like what economists call a “model.”

Suppose you are unborn. You don’t know where you’ll be born. You might be born in a middle-class suburb of Cleveland, Ohio, or a shantytown in Bangladesh, or the latest scion of the British royal family, or in a refugee camp in Pakistan. Of course, this is the famous Rawlsian “original position,” but where I’m going with it is a bit different. My question isn’t “how would you design the world?”– though that’s certainly an interesting question which, I think, must have a pro-open borders answer. What I want to ask, though, is different. Suppose you know enough about the world that you know where you’d like to live– America, Switzerland, China, Mozambique, Italy, whatever. The question is: What are your odds that you can get your wish? Continue reading Rawlsian Locational Choice (a highly abstract open borders metric) →

An offbeat argument for immigration restriction

3 Comments

I’m always on the lookout for new, innovative arguments against immigration. Restrictionists tend not to disappoint in coming up with creative arguments, but usually these are modest permutations and perturbations of existing arguments. Recently, however, I encountered an honestly creative, offbeat, and mind-blowing argument for immigration restriction. If I had to classify it, it would come under political externalities or under second-order harms. But neither classification does justice to the sheer creativity of the objection. The credit goes to none other than restrictionism’s most creative proponent, Steve Sailer.

Sailer makes the argument in this EconLog comment, which I’ll take the liberty of quoting in full (emphasis mine):

92% of elected Hispanic officials are Democrats. So, self-appointed Hispanic leaders tend to be overwhelmingly liberal. One reason is affirmative action. Most of these self-annointed leaders are affirmative action beneficiaries, and they have two self-interests: preserve ethnic preferences for Hispanics and increase the number of Hispanics in the country to make themselves appear more powerful.

The way out of this trap is for Republicans to eliminate all affirmative action (including disparate impact discrimination lawsuits) for Hispanics and to close the borders. After a period of wailing and gnashing of teeth, new Hispanic leaders will arise who actually represent the interests of Hispanic voters, not of themselves.

I vaguely recall reading a similar argument by Sailer elsewhere, but I can’t find any other link at the moment. Let me abstract Sailer’s framework. Some Hispanics immigrate to the United States. They increase the total number of Hispanics. Sailer is not concerned (in this comment) about whether these particular Hispanics agitate for affirmative action, or for any of the policies Sailer disfavors. He is not complaining about their actions, either in the economic and social realm or through the political channel. His complaint here is that their sheer existence in the United States makes it easy for self-appointed Hispanic representatives (who are often natives, not immigrants) to point to their numbers and make the case for certain policies (such as affirmative action) which Sailer considers harmful to the United States. And note that the people to whom they’re making the case are also usually natives, not immigrants. In other words, the existence of immigrants makes it easier for some natives to convince some other natives of policies that Sailer considers harmful to the United States. This, according to Sailer, is sufficient justification “to close the borders” as Sailer puts it.

Frankly, Sailer’s argument is a trump card, and there really isn’t much I can say in response. If people’s mere existence inside of a border, rather than what they do or don’t do, is sufficient grounds for closing a border, then it’s time for open borders advocates to pack up. Restrictionists win hands down, just as they do when they use pure racialist arguments.

IQ and double counting the harms of immigration

22 Comments

Nathan just published a lengthy and detailed critique of various critics of open borders. I think he gets many things right, but in some ways he underestimates restrictionist arguments. This isn’t entirely Nathan’s fault — restrictionists often don’t frame their arguments cogently and clearly, and it’s extremely hard to understand their arguments without spending considerable time going through them. I want to talk about one particular restrictionist argument — the IQ deficit argument, and what I think an appropriate response to this argument is. This post is not intended to address specific restrictionist critiques of IQ. I’ll do that in subsequent posts. For now, my main goal is to explain my overall position.

Now, some open borders advocates find the entire discussion of IQ off-putting and are quick to make accusations of racism and invoke negative stereotypes for restrictionists. (To take just one example of where this came up, consider the comments section of this blog post where I came under fire for engaging IQ-based arguments in the context of immigration). I do not adopt this approach for multiple reasons, most important of which is that I think some of the basic premises underlying the IQ deficit concern are valid. And, my goal in this blog post is to address IQ-based objections, not to dismiss them.

I’ll state the IQ deficit argument for immigration to the United States, though the general framework is applicable to immigration to other countries as well.

  • IQ is meaningful, measurable, and correlated with a number of real-world performance metrics. Higher IQ people tend to be more cooperative, less criminal, more innovative, better and more informed voters, etc. These correlations hold even after we control for other things such as education levels. A high IQ person without much formal education would tend to be more cooperative than a low IQ person with a similarly low formal education: Basically, I think this is correct. It seems to agree with the Mainstream Science on Intelligence and Intelligence: Known and Unknowns. Recent work by Garett Jones has strengthened economists’ appreciation of the link IQ and cooperation and its role in economic development, something whose implications I considered in this blog post.
  • Adult IQ is fairly stable (though it can go down with head injuries and certain illnesses). It cannot usually be made to go up significantly. Childhood IQ may be malleable, but we don’t quite know how to manipulate it much on the positive side, though probably malnutrition and childhood disease affect it on the negative side. I think this is broadly correct too. This also agrees with the two consensus statements above.
  • Under open borders, the average IQ of immigrants to the United States is lower than the average IQ of current United States residents: International IQ data comparisons are not very solidly established, but the preliminary evidence suggests that this is likely to be true. If Lynn and Vanhanen’s data are to be believed, then the average world IQ is about 2/3 of a standard deviation below average US IQ. I’m not very confident about this, but it’s plausible.
  • The stability of adult IQ means that even after migration, the lower average IQ of immigrants will pull down the average IQ of the United States. This seems fairly plausible to me.

At this point, Nathan jumps in and says, “Ah! Even if correct, this is not as relevant as you think. You’re committing the maximize the average fallacy and refuse to understand the comparative advantage concept.”

Not so fast, restrictionists would say. As Richard Hoste puts it, the comparative advantage argument works in the context of pure economics, but once we bring in crime and political externalities, it starts to falter. If crime rates go up, then your chance of being a crime victim goes up, all else equal (there are caveats to be added, but I’m using a simplistic picture of crime). Comparative advantage doesn’t come to the rescue here. And if low IQ means voting for bad policies (something that’s supported by Caplan’s research) then low IQ immigration would lead to negative political externalities.

So, I don’t think the comparative advantage argument is quite the right way to tackle the IQ deficit concern. So what is? I think we need to step back a bit and be clearer about how IQ matters to the moral and practical considerations that come up with respect to immigration and its effect on natives and immigrants. Does IQ matter in and of itself (as some indication of moral worth or desert), or does it matter because of its correlation with things like crime or political beliefs or social capital or what-have-you? It’s only the rare IQ elitist who argues that IQ is morally significant in and of itself. Most people who believe in the importance of IQ believe in it because it’s correlated with a lot of other things like crime, political beliefs, etc.

This brings me to the crux of my objection to the IQ deficit concern. If lower immigrant IQ raises concerns about higher immigrant crime rates or wrong political beliefs, then that should show up in the evidence on immigrant crime rates and political beliefs. If it does show up there, then great, score a point for restrictionists, and now that we’ve done that, what additional information does immigrants’ IQ deficit give us? By saying that immigrants commit crime and that immigrants have a low IQ which means they would commit more crime, it seems like restrictionists are double counting crime.

What if restrictionists are unsuccessful in demonstrating higher immigrant crime? That does seem to be the case with current levels of immigration to the United States. As things stand today, the foreign-born have lower crime rates than natives both in total and for every ethnicity and for every combination of ethnicity and high school graduation status.

Some restrictionists look these data in the eye and say, “Immigrants have lower IQ, therefore they must be committing more crime, no matter what the data say.” I think the data on crime rates aren’t wrong, so let me engage restrictionists by offering alternative explanations within their explanatory framework of low IQ being correlated with higher crime rates. The first possibility is that the restrictionists may be wrong about their claim of lower IQ of current immigrants to the United States. The second possibility is that there may be certain other differences between the foreign-born and native-born Americans that compensate for the lower average IQ to push the overall averages in the other direction. Those differences may be in terms of the culture or in terms of the structural incentives and constraints faced by the foreign-born relative to natives. But whatever the story, I think that when restrictionists find that a particular predicted ill-effect of low immigrant IQ fails to materialize, then they should give up on that and concentrate on the other claimed bad effects. And, perhaps, also double-check their claim of lower immigrant IQ while they’re at it.

So my overall claim is that restrictionists who think the IQ framework is a good overarching framework within which to fit their objections can certainly offer this framework. But they should not double count harms by both including the harm itself and the IQ deficit channel for the harm as separate harms. And if a harm predicted by IQ deficit fails to materialize, they should sportingly concede the point and move on. Which means that IQ deficit ultimately serves only as a framework, not as an argument in and of itself.

I will now address a few possible objections that restrictionists might raise to what I’ve said above. Continue reading IQ and double counting the harms of immigration →

Crime in the US under open borders

16 Comments

Crime is a common concern regarding immigration among US restrictionists. The statistics on immigration and crime in the United States show pretty clearly that as things stand today, the foreign-born have lower crime rates than natives both in total and for every ethnicity and for every combination of ethnicity and high school graduation status. Nathan recently blogged about how immigration might also indirectly reduce native crime rates. So, restrictionists need not be worried about immigrant crime under the status quo.

But there’s still the concern about radical open borders to contend with: even if restrictionist concerns about immigrant crime are misplaced at current rates of migration, the concern may still be valid for truly open borders. Is it? It’s hard to say anything definitive, so if you believe in the precautionary principle, this is a slam dunk argument against open borders. However, I will try to argue in this post that there is no strong reason to believe that open borders would lead to a significant upward trend in US crime rates. In fact, I would say that the odds of crime rates going up versus down are about even, and they almost certainly will not explode.

The first point I will make is that even under the current highly restrictive immigration laws, there is some immigration, including “low-skilled” immigration, to the United States from all parts of the world. While border-crossing from Mexico forms the lion’s share of “low-skilled” immigration to the United States, there are also a few low-skilled work visas and, more importantly, a diversity visa that is not designed to pick out high-skilled workers but rather favors countries that send few immigrants to the United States. Thus, the current data on immigration and crime in the United States does shed some light on what might happen under a radically freer migration regime.

However, I will, for the moment, set this point aside. Assume for the moment that current immigration from a country is completely unrepresentative of what immigration from the country would look like under open borders. What method can we then use to approximate crime rates for immigration from that country? We could look at average crime rates in the sending country. I would argue that this would overestimate their crime rates in the United States for three reasons: Continue reading Crime in the US under open borders →

More responses to Caplan’s critics

NOTE: All commenters are referred to as “he” in the text below. I did this because the only commenters whose pen names were gendered were male, and in my experience, most commenters on libertarian blogs seem to be male. I suppose I could have used the singular “they” but it seems ungrammatical when one is referring to a specific person. Apologies to any female commenters who might have been misidentified by my choice of pronoun.

Open borders is the most one-sided issue of our times. It wins the argument and to spare. That’s my position, and if there’s a certain bravado about it, that’s my way of daring those who disagree with me to justify themselves. I want to flush out the arguments against open borders, so I can refute them. Yet to argue with run-of-the-mill immigration critics is a tedious business, because their intellectual level is so low (see my dissection of Victor Davis Hanson) that the response could only consist in cutting through crude prejudices and elementary fallacies. Bryan Caplan’s Open Borders Persuasion Bleg a few days ago was useful because he evokes a more intelligent kind of critic. Indeed, as I noted in my previous response to Caplan’s critics, Caplan has managed to muster, in his comments section, the most clear-thinking group of critics of open borders on the web, because they’ve seen him make the case for open borders in its glittering clarity. They are informed dissenters. Though still mistaken.

Caplan started the thread with this invitation:

Immigration restrictions probably have bigger effects on the world’s economy than all other regulations combined.  As far as I can tell, virtually every moral theory – utilitarian, libertarian, egalitarian, Rawlsian, Kantian, Christian, and Marxist for starters –  implies that these effects are very bad.  As a blogger, I’ve tried (though perhaps not hard enough) to make open borders my pet issue – to convince as many people as possible that the cause of free immigration is of overriding value.

My question for you: How persuasive have I been?  In particular, how persuasive have I been for you personally?  Yes, polling your own blog readers obviously courts a strong selective bias, but I still want to hear your answers.

There were probably more positive than negative responses to this introduction, including some who were completely converted to the open borders cause from indifference or hostility. I’ll focus on the negative responses though because they show what we still need to work on. I’ll cover most of them, but skip the long comments from Ghost of Christmas Past because they would need their own post.  Continue reading More responses to Caplan’s critics →
