I couldn't have said it better myself.
Post #14 indicates this guy has no particular training in Evolutionary Biology. The article calls him a “Evolutionary Psychologist” if there is such a thing, maybe Dr. Charlton is one; but Ive seen nothing to indicate it.
Moreover he makes reference to no particular data set or study that I can check the methodology of.
Without any apparent expertise in the subject, and without reference to any particular study, all we are left with is the opinion of a British Psychologist that there is no reason to make room for (presumably qualified) “working class” students at elite Universities because they score lower on IQ tests as a group and that is somehow because of “bad” genetics instead of a host of other cultural and environmental factors.
