“Insofar as intelligence is the chief cause of social inequality between groups, one should expect them to attain roughly equal outcomes.”

No, actually iq, which you have shown some data for, not intelligence, is just a correlation. I realize that for people without much intelligence the distinctions can be difficult to grasp. But do try to figure it out. Causation is much more difficult to determine and way more complex than your statement implies, and iq scores don't capture the whole of intelligence.

Due to the general increase of unadjusted iq scores over time (now often referred to as the “Flynn effect”) even people today who score relatively low on iq tests are still scoring higher than the average person 100 years ago, but we have no compelling reason to think that people 100 years ago were dramatically more inclined to commit crimes -- that is, the people with an average iq 100 years ago did not on average commit the same amount of crime on average as people with relatively lower IQs today. The same applies for other “social inequality” that correlates with iq scores. If low IQs were causing many of the things correlated with them, we would at minimum expect those correlations to hold strongly for their raw iqs into the past, but they do not.

Palestinians today are scoring higher than the average European or American 100 years ago. Yet, in Denmark, at least, they are on average much more violent and indolent. Iq is thus a very poor candidate for causal explanation. I would be curious to see though if you can demonstrate the average Dane 100 years ago had a similar social profile as the average Palestinian today. Or perhaps instead of the average Dane, show the average Jew had the same profile. Maybe that could explain why some Jews decided to colonize Palestine and violently expel so much of its inhabitants almost 100 years ago because they believed in a superstitious right to the land? They had low iqs. I don’t suspect that is true though. Stupidity, barbarity, and iq are only loosely correlated.

If you do not understand my argument, perhaps in a century or two, after average unadjusted iq scores have dragged your iq sufficiently forward, or you simply overcome your bigotry, you will. I suspect bigotry has a substantial damaging causal effect on intelligence.

EDIT: If you want to watch a ted talk with the guy whose research the "flynn effect" was named after, you can watch it here: https://www.youtube.com/watch?v=9vpqilhW9uI

He discusses what I referred to as "general increase of unadjusted iq scores over time " and the "flynn effect". He explains it well; after all he discovered it.
