In The Alt-Right and its Failings, Part 1, I wrote about how the alt-right prescribes regressive solutions to problems like college costs, essentially arguing for a drastic reduction in scope, and a return to IQ-based employer screening. What I did not mention is that this is based in a sort of hereditarian, elitist argument.
Unlike mainstream conservatives, alt-righters believe that well-adjusted, functional behavior is biologically ingrained, and that some groups of people (particularly blacks) are notoriously poor at it due to some kind of biological shortcoming. The alt-right's "objective" means for claiming this is the one-standard-deviation difference in IQ between whites and blacks.
The problem is that, as Robert Lindsay and others have pointed out, IQ scores are not a reliable means for predicting maladaptive behaviors. Yes, the White->Hispanic->Black hierarchy holds, but once you start throwing other races in, the picture gets much murkier. And then when you compare the IQs of, say, middle easterners to that of American Blacks, the latter actually score higher. Yet middle easterners commit far less crime.
This leads me to believe that the IQ theory of alt-righters is another just-so story that doesn't come close to explaining the full truth. It is true that blacks suffer more social dysfunction than whites, which is reflected in crime rates and the rates of single motherhood. But they should be doing far better if one takes their IQ into account.
I have an alternate explanation: Many of our problems in society are caused by underinvestment in infrastructure and other public goods. Blacks, who tend to be quite poor, suffer the most from this deficiency. How easy is it for them to get from point A to point B? How intellectually stimulating is their environment, or is it just a run-down ghetto? How good is their health care, and the quality of their food? By many objective measures, these areas are in dire need of improvement.
There is also the cultural aspect. How are the relations between the genders, and parents/children? Are kids seen as a society's future, or just something that a babymomma takes care of? Do women select for intelligent, caring men, or do they just go after thugs? This is all stuff that can be fixed with the right attitude (read: shaming.)
So while some black problems could be due to genetics, I think the vast majority of them are because of 1) a poor environment and 2) poor cultural attitudes, both internal and external. Alt-righters are not helping in this regard. They want to starve the state, which will cause poor black areas to crumble even more. They also promote the idea that most blacks essentially "deserve" their status, instead of it simply being a consequence of unfortunate coalescing forces.
I think this is one reason why the alt-right disparages the manosphere. You see, the manosphere is trying to fix the problems of societal decay, which begin with environmental and familial decay. Some prominent manosphere commentators are black, and have come from broken families. Yet the alt-right sees them as "blacks" instead of "men."
I don't think there is much in the alt-right sphere for people for actually want to improve the general well-being of society as a whole. Their prescriptions are all backwards, and won't do a lick of good for anyone in the long run.
