An Ineffective Strategy With Worrying Implications
Wait what? We are launching a DDOS attack against North Korea. Could we do anything more stupid? Its not like North Korea uses the internet enough for this to represent a serious inconvenience to the nation while at the same time we legitimize the use of cyber attacks against civilian infrastructure as a way to settle international disputes. Dear god this is a bad idea!
As the US reportedly conducts a denial-of-service attack against North Korea’s access to the Internet, the regime of Kim Jong Un has gained another connection to help a select few North Koreans stay connected to the wider world-thanks to a Russian telecommunications provider.
Here is a bit of hard data to respond to the claims that observed performance on IQ tests by those in third world countries reflect genetic deficits. Its a good thing too (even if this was hardly the first piece of evidence on the point) since its easy to imagine that the world could have turned out in a way in which (despite race not being a scientifically useful category) third world populations also suffered from genetic intelligence disadvantages. There is a decent case to be made that the Ashkenazi Jews have genetic differences given them higher average IQs. Notably that case doesn’t merely depend on differences in performance on some tests but, likely all compelling scientific arguments, weaves together an explanation of a number of different phenomena with an appealing theoretical account1. Whether or not this ultimately turns out to be true it could have been true and other undisputed cases of recent evolutionary pressure like adult tolerance for lactose make it abundantly clear that we got very lucky that there aren’t major differences in genetic predisposition to IQ across people of different descent and seeing studies like this reassures me that we really did get lucky and its not just that we are laboring under a desirable fiction.
Even though our racial categories don’t correspond to any principled scientific division at the genetic level it is a classification that correlates with ones ancestry. Given that people still tend to choose mates relatively close to themselves genetically (whether or not race is salient to them or merely geographic proximity) that means it could easily have been the case that, even supposing all developmental and social effects are controlled for, that some races would average much, much worse on IQ tests and other measures of intelligence than others. It wouldn’t really matter that race wasn’t the best scientific category to explain the effect if it turned out that 80% of people we classified as black had genes which cost them 20 IQ points while only 20% of Caucasians and 30% of Semites had this genetic combination. Such a fact would have amplified existing prejudices and resentments making it much more difficult to roll back racist attitudes and laws. In such a world I doubt one of the 20% of blacks without those genes would have had much luck explaining to the white racists around them that no, no, black isn’t the appropriate scientific concept with which to analyze this effect its really this other grouping they should be using, e.g., one which is purely defined via heredity and doesn’t exactly track our racial divisions but just happens to correlate with them.
One might try and argue that there is too much human genetic mixing for substantial genetic differences in IQ to have arisen. While it is true that for the most part humans haven’t partitioned themselves into non-interbreeding (or at least rarely) sub-populations that only holds for the most part and is itself purely a lucky accident. Australian aborigines appear to have been genetically isolated for almost 50,000 years with that isolation only ending quite recently2. There is evidence that the San people in Africa may split off from the rest of the human lineage at around the time modern homo sapiens first arrived on the scene and were then genetically isolated for nearly 100,000 years until only 40,000 years ago. There is no scientific law that ensured there weren’t major genetically isolated branches of the human species with substantially different intellectual abilities which remained separated until the end of the middle ages. It didn’t have to be the case that America was populated by genetically modern humans3 and for less extreme cases one doesn’t even need genetic isolation at all. One can imagine a scenario in which the black death is even worse and attacks the neural system creating strong selective pressure in Europe for a mutation which protects against it despite its detrimental effects on IQ. I suppose one could argue that people are just too rapacious and generally willing to fuck each other for differences to have persisted during the historical era but that is only true if all populations were subject to the same selective pressures and one could certainly imagine a scenario in which only farmers and not hunter gatherers (or vice versa) experience selection for the kind of mixed blessing genes postulated to be more prevalent in the Ashkenazi.
Of course, if we learn enough about genetics and perform sufficiently high powered studies we will probably come across some minor statistical difference in IQ between racial groups. If we assumed that humans were all otherwise genetically identical the small IQ advantage observed in Ashkenazi Jews would be enough to ensure that sufficiently powerful studies would find some average difference. Of course we aren’t all otherwise genetically identical and surely the beneficial and detrimental mutations won’t perfectly cancel out on average. But the fact that we haven’t already found substantial differences and don’t even know who will come out on top if average differences are ever found already means that we got incredibly lucky. It didn’t have to be that the HBD people were wrong, it didn’t even half to be that our racial categories didn’t track scientifically important genetic fault lines. Even though many of the HBD proponents seem so desperately motivated to believe their theories (and not all for racist reasons…some just want to be contrarian) their views certainly describe a way the world could have been and we got quite lucky that human capacities ended up sufficiently close together and interbreeding smeared us out enough that we can’t obviously pick out the more and less capable major ethnic groups.
In Selfish Reasons to Have More Kids, I showed that nurture effects are small within the First World. But I also freely conceded that the nurture effects of growing up outside the First World are probably large:The most important weakness…
In this case the theoretical account suggests that certain mutations which both increase intelligence but also increase susceptibility to certain congenital disorders were selected for in Jews living in medieval Europe and laboring under systematic discrimination which kept them out of most occupations while concentrating them in a few occupations for which IQ was particularly important. ↩
Though one could, I suppose, argue that had the aboriginal Australians, contrary to fact, been intellectually impaired relative to other humans then relatively nearby populations would have noticed and used their superior intelligence to supplant them. ↩
For a truly extreme scenario, one could imagine an “out of America” theory of human evolution in which 200,000 years ago proto-humans leave America over the land bridge which subsequently closes (and weather/sea conditions prevent coast hopping) it is only in 1492, after modern humans evolve in the rest of the world, that we rediscover the lost American branch of the human tree. ↩
Don't We Want More Happy Parents, Healthier Pregnancies and Genetically Advantaged Children?
Julia Galef has more from her wonderful unpopular ideas series. This one covers unpopular ideas about children and reproduction. There’s a lot of interesting ideas in there but the one I found most appealing, though unfortunately pretty unlikely to be adopted, was the suggestion that we should allow parents to ‘sell’ their newborns.
There are some obvious problems with allowing people to do this in the third world. In traditional subsistence farming contexts children may offer a net economic gain to a family particularly if given only minimal accommodations. No one wants to return to the halcyon days when we hired children out as indentured servants where unsympathetic farmers would `raise’ them in Dickensian conditions. However, in the developed world even the most neglected child is still a net economic cost so we can safely assume no one will be buying children to have someone they can extract work from without the guilt of mistreating their own offspring.
Such a policy would help many loving couples find children to adopt and I even believe there is a real benefit to removing children from the care of anyone so uninterested in them (or convinced they are unfit) that they are willing to make such a sale1.
But won’t this just result in drug addicts and other unfit parents popping out babies left and right for a bit of cash? Well maybe some college profs with oxy addictions might but babies to fund their habit but those babies would be in demand from parents who will offer them a good home (and unlike alcohol there is no analogous fetal opiate, meth or even crack syndrome). However, I suspect (but haven’t been able to find statistics on this) that the children born to street addicts already have plenty of problems finding adoptive parents. Moreover, pregnancy is a long, difficult process that its safe to assume anyone who finds it worthwhile to grow babies for sale is offering a high-value baby (good genes and health) who will be placed in a comfortable living situation.
What about the idea that it would incentivize women to choose the couple willing to pay the most for the child rather than the best family? First, I’m skeptical of the ability of birth mothers, given the lack of truly extensive interactions and their limited control over the process have any particular ability to pick good parents. Indeed, I suspect that the ability and willingness of the adopting family to pay would actually be a better indicator of the child’s future welfare than any gut level instinct. Second, when a birth mother decides between two potential families wanting to adopt the families who weren’t selected presumably still go on to adopt someone making this whole matter a wash from a social welfare perspective.
Basically, selling babies isn’t really any different than the surrogacy arrangements we are already comfortable allowing except that it no longer incentivizes people to only pretend to be willing to give the child up or to squeeze more money from the deal with a last minute change of heart. Where surrogacy arrangements incentivize the pregnant woman to divert money intended to increase the child’s health to their own pockets baby sales incentivize offering documented high quality care to maximize sale value.
Really, the only downside I can really see is just how obvious it will make our racial preferences in children. White babies will be worth way more than black ones.
In developed countries there is little reason to fear that more people would be extorted to sell their children if the practiced was legalized. One might imagine that in war torn parts of the world a market in children would give warlords the bright idea of forcing women to sell their children and give them the money. In the first world the only pressure on a woman to sell is the crappy circumstances she would be in whether or not baby sales were legal and if that induces her to make a sale I suspect everyone will be better off as a result, particularly the child. ↩
Do We Really Want To Stop Victims of Harrasment From Learning What's Being Said About THem?
I pretty much agree with everything Prof. Volokh says in this post but I would add that is is particularly disturbing and dangerous that these claims not only made it to the lawsuit stage but also that sufficiently many people in the Feminist Majority Foundation (not mainstream but not tinfoil hat nutters) thought this was worth pursuing.
Sure, demanding censorship of mean, hurtful and demeaning comments about your group or identity isn’t anything to write home about. However, what really sets this situation apart is that the demand wasn’t to punish the anonymous individuals responsible but to stop students from choosing to access an information source because it might allow them to read these awful things.
Demands for censorship in response to hurtful/mean/awful comments is nothing to write home about (from either side of the political aisle) but I think something is particularly distasteful about demanding policies that would allow all the assholes in a 5 mile radius to continue attacking, degrading, spreading hurtful gossip about and otherwise making life bad for some women on campus while barring those very women from keeping abreast about what is being said about them so they can refute malicious gossip, take threats to the police and otherwise protect themselves (reputationally and physcially).
Sure, I know those filing the suit no doubt intended to discourage people from posting such hateful and derogatory remarks in the future by eliminating the on campus audience for them. However, this line of argument could equally well be used to deny students access to a contrarian blog (say by a former student) making an extended argument that, because of innate ability differences, the schools affirmative action policy was driving reductions in academic rigor/performance. Even if the students visiting the blog were driven by simple curiosity and desire to evaluate the claims for themselves, if the continued posts were clearly motivated by the blogger’s desire to reach so many students with his message there would be an equally strong argument for barring students from accessing the site. With the predictable result that it would probably only increase the extent to which students agree with those unpopular views (the feeling that a view is being suppressed is far more alluring than poor arguments for it).
In a different context I would be far more charitable. If a private university were being asked to ban the platform I’d still oppose the suggestion but it wouldn’t really be fair to suggest the proponents would be responsible for denying victims a chance to (easily) make themselves aware of attacks against them so they can respond. After all, the advocates would be presumably be suggesting that in the particular case the benefits would outweigh the costs. However, the plaintiffs were asking the courts, an institution designed to apply predicatable precedent not case specific balancing, to rule that such an outcome was required. As such I do think its fair to point out the plaintiffs are asking for a rule which, in many of its applications, would deny the victims warning and an ability to respond without substantially reducing the torrent of hate and insults.
The fact that this resulted in a full court case with published opinion makes me worry that the argument was either plausible enough that reasonable lawyers thought it had a chance of prevailing or, perhaps more likely, those advancing the suit felt the risk of enduring such a lawsuit would discourage universities from being quite so protective of free speech in the future. Particularly so for private universities who aren’t bound by any need to comply with the first amendment.
University of Mary Washington had no obligation to “ban Yik Yak from the campus wireless network ,” because such a ban “may have exposed the university to liability under the First Amendment” (and in any case wasn’t required by Title IX or the equal protection clause.
So online there have been some suggestions that shooting a bullet into a hurricane could send it back to you by wrapping it around the eye.
So based on the images presented on wikipedia area presented by a 7.62mm rifle bullet to a wind striking it from the side is less than 12mm x 30 mm but more than 1/2 that so at least .00018 m^2. The minimum hurricane wind speed is 33 m/s so plugging it into the wind load calculator giving us about .12 Newton. This compares to the force of gravity of about .01kg *9.8 ~ .1 Newton. Yet fired straight up a bullet will only travel on the order of a kilometer while the size of a hurricane eye is typically 30+ km in size.
So no, a bullet won’t wrap around the hurricane and come back to hit you. The wind effect simply whips it off course too quickly to do a full circuit but one could hit something unintended if one fires with a strong cross wind.
I strongly suspect that simple range limitations would be an easier way to figure this out but I found the calculation kinda fun.
So I see people posting this vox article suggesting Trump, but not Clinton, supporters are racist and I want to advise caution and urge people to actually read the original study.
Vox’s takeaway is,
All it takes to reduce support for housing assistance among Donald Trump supporters is exposure to an image of a black man.
Which they back up with the following description:
In a randomized survey experiment, the trio of researchers exposed respondents to images of either a white or black man. They found that when exposed to the image of a black man, white Trump supporters were less likely to back a federal mortgage aid program. Favorability toward Trump was a key measure for how strong this effect was.
If you look at the actual study its chock full of warning signs. They explicitly did not find any statistically significant difference between those Trump voters given the prompts showing black or white aid recipients degree of support for the program or degree of anger they felt or blame they assigned towards those recipients. Given that this is the natural reading of Vox’s initial description its already disappointing (Vox does elaborate to some extent but not in a meaningfully informative way).
What the authors of the study did is asked for a degree of Trump support (along with many other questions such as liberal/conservative identification, vote preference, racial resentment giving researchers a worryingly large range of potentially analysises they could have conducted). Then they regressed the conditional effect of the black/white prompt on the level of blame, support and anger against degree of Trump support controlling for a whole bunch of other crap (though they do claim ‘similar’ results without controls) and are using some dubious claims about this regression to justify their claims. This should already raise red flags about research degree of freedom especially given the pretty unimpressive R^2 values.
But what should really cause one to be skeptical is that the regression of Hillary support with conditional effect of black/white prompt shows a similar upward slope (visually the slope appears on slightly less for Hillary support than it did for Trump) though at the extreme high end of Hillary support the 95% confidence interval just barely includes 0 while for Trump it just barely excludes it. Remember, as Andrew Gelman would remind us the difference between significant and non-significant results isn’t significant and indeed the study didn’t find a significant difference between how Hillary and Trump support interacted with the prompt in terms of degree of support for the program. In other words if we take the study at face value it suggests at only a slightly lower confidence level that increasing support for Hillary makes one more racist.
So what should we make of this strange seeming result? Is it really the case that Hillary support also makes one more racist but just couldn’t be captured by this survey? No, I think there is a more plausible explanation: the primary effect this study is really capturing is how willing one is to pick larger numbers to describe one’s feelings. Yes, there is a real effect of showing a black person rather than a white person on support for the program (though showing up as not significant on its own in this study) but if you are more willing to pick large numbers on the survey this effect looks larger for you and thus correlates with degree of support for both Hillary and Trump.
To put this another way imagine there are two kinds of people who answer the survey. Emoters and non-emoters. Non-emoters keep all their answers away from the extremes and so the effect of the black-white prompt on them is numerically pretty small and they avoid expressing strong support for either candidate (support is only a positive variable) while Emoters will show both a large effect of the black-white prompt (because changes in their opinion result in larger numerical differences) and a greater likelihood of being a strong Trump or Hillary supporter.
This seems to me to be a far more plausible explanation than thinking that increasing Hillary support correlates with increasing racism and I’m sure there are any number of other plausible alternative interpretations like this. Yes, the study did seem to suggest some difference between Trump and Hillary voters on the slopes of the blame and anger regressions (but not support for the program) but this may reflect nothing more pernicious than the unsurprising fact that conservative voters are more willing to express high levels of blame and anger toward recipients of government aid.
However, even if you don’t accept my alternative interpretation the whole thing is sketchy as hell. Not only do the researchers have far too many degrees of freedom (both in terms of the choice of regression to run but also in criteria for inclusion of subjects in the study) for my comfort but the data itself was gathered via a super lossy survey process creating the opportunity for all kinds of bias to enter into the process not to mention. Moreover, the fact that all the results are about regressions is already pretty worrisome as it is often far too easy to make strong seeming statistical claims about regressions, a worry which is amplified by the fact that they don’t actually plot the data. I suspect that there is far more wrong with this analysis than I’m covering here so I’m hoping someone with more serious statistical chops than I have such as Andrew Gelman will analyze these claims.
But even if we take the study’s claims at face value the most you could infer (and technically not even this) is that there are some more people who are racist among strong Trump supporters than among those who have low support for Trump which is a claim so unimpressive it certainly doesn’t deserve a Vox article much less support the description given. Indeed, I think it boarders on journalistically unethical to show the graphs showing the correlation between increasing support for Trump and prompt effect but not the ones showing similar effects for support of Hillary. However, I’m willing to believe this is the result of the general low standards for science literacy in journalism and the unfortunate impression that statistical significance is some magical threshold.
All it takes to reduce support for housing assistance among Trump supporters is exposure to an image of a black man. That’s the takeaway from a new study by researchers Matthew Luttig, Christopher Federico, and Howard Lavine, set to be published in Research & Politics.
Regardless of your views on transgender children how is this not a no brainer? The competing interest in allowing girls to wear skirts is only that it lets them express themselves as identifying as female but if you believe that self-expression is more important than the uniformity and equality conveyed by having all students wear the same outfit you shouldn’t be having students wear a uniform in the first place.
I mean something is seriously weird about a policy which tells children that generally conformity and equality are more important than expressing your individual features except for your gender. At best it suggests that gender is a particularly important division, more important than interests, abilities or other personal characteristics. At worst it encourages teachers to apply gender based stereotypes.
Perhaps you are skeptical that the mere symbolic differentiation between boys and girls would have any real effect. Maybe not. But if you don’t believe these kinds of symbolic distinctions make real differences what are you doing insisting on uniforms in the first place1? If you don’t believe that uniformity sends any important message but are willing to suppress the full range of individual student expression just for disciplinary convenience then surely the issues raised by girls wearing shorts (skirt length etc..) alone are enough to justify eliminating this last, much less valuable, irregularity even ignoring the extra concerns raised about gender.
“But when it was explained to us, it was about inappropriate dressing, I think it was the right decision to make.” The new uniform only applies for Year 7s but students in Year 8 to Year 11 are welcome to adopt the new uniform.
One might try and suggest that uniforms are important to disguise income differences between parents but that this concern doesn’t implicate any strong symbolic value to the uniformity of the outfit. However, it certainly acknowledges that wealth differentiation based on student outfits make a big difference. Moreover, as someone who had to wear uniforms at school growing up I’m skeptical of this justification. It is still easy to tell who has money as expressed through haircuts, backpacks and other accessories (and tailored higher quality uniforms at some schools) and the uniforms themselves must be purchased in addition to casual outfits (except perhaps at some boarding schools) and differentiation based on parental income is generally less intense than differentiation based on style/interest. ↩
This is an interesting piece but I couldn’t disagree more with the title or the author’s obvious feeling that there must be a cynical explanation for techie’s distrust of government regulation.
Silicon valley types are simply classical pragmatic libertarians. They aren’t Ayn Rand quoting objectivists who believe government intervention is in principle unacceptable. Rather, they, like most academic economists, simply tend to feel that well-intentioned government regulation often has serious harmful side effects and isn’t particularly likely to accomplish the desired goals.
I think this kind of skepticism flows naturally from a certain kind of quantitative results oriented mindset and I expect you would find the same kind of beliefs (to varying degrees) among the academic physicists, civil engineers and others who share the same educational background and quantitative inclination as silicon valley techies. I’m sure that the particular history of poorly understood tech regulation like the original crypto wars in the 90s plays a role but I suspect it just amplified existing tendencies.
But by the 1990s, with the advent of the World Wide Web and the beginning of the tech industry’s march to the apex of the world’s economy, another Silicon Valley political narrative took root: techies as unapologetic libertarians, for whom the best government is a nearly nonexistent one.
Missing from this list is the suggestion that we should be maximizing the economic value of convicted felons by making them use their skills to earn money to be paid to the state and the victim. There was an interesting post about this on econolog not too long ago and while practical considerations may limit the application of this idea I think it is something we should more seriously consider.
I mean a large amount of support for increasingly harsher punishments seems driven not by the idea that it is necessary for ideal punishment but by horror at what happened to the victim. But, to the extent that is true, maybe the victim should get the choice between longer/more extreme punishment and letting the perpetrator work in a more lucrative fashion to better compensate them. True, this would mean that less skilled/educated criminals might get the worse end of the stick but criminal justice is about making the best choice from bad alternatives and if we can better compensate some victims by letting the perpetrator work for more money maybe we should consider it.
I’ve been compiling lists of “unpopular ideas,” things that seem weird or bad to most people (at least, to most educated urbanites in the United States, which is the demographic I know best). Because my collection of unpopular ideas became so long, I’ve broken it into categories.
NASA’s Cassini probe is plunging to its death. The nuclear-powered spacecraft has orbited Saturn for 13 years, and sent back hundreds of thousands of images. The photos include close-ups of the gaseous giant, its famous rings, and its enigmatic moons – including Titan, which has its own atmosphere, and icy Enceladus, which has a subsurface ocean that could conceivably harbour microbial life.
