I do have a certain skepticism about IQ scores, and I do understand that they can be (but do not necessarily have to be) fodder for racist views --- but is IQ strictly out of bounds, even as one data point out of many to be considered?
Whole lot of guilt-by-association here.
IQs are racist because certain groups score at what you would expect, and we want to believe that everyone can grow up and be an astrophysicist.
