If there is any real scientist left in the social science field they really should object to political activist posing as scientist and publishing this sort of dribble. It isn't science it is simple read meat for the liberal base meant to reaffirm their deep belief that they are the smart ones.
What do you want to bet these same scientist would object to fact that IQ show males are smarter than females and whites are smarter than blacks, a lot smarter. Mention those things and you will likely hear a lot about the inaccuracy of the test and how he test is biased. The same test they use to show how much smarter they are will suddenly be invalid. Social science is a fascinating field that has been ruined by people looking to prove what they want to believe is true or what they want everyone to believe is true. Climate research has the same problem. Political activist have no place in science.
Might as well argue with the ground about how much longer winter will last. At least he isn’t pushing a political agenda.
