Consider the idea that maybe you are wrong; read the book I'm recommending (which is short and thoroughly cited) and I will read The Mismeasure of Man a third time, which may be one of the most dishonest books ever written. It is the case that social science post 1950s largely failed to address the idea that cognitive ability is heritable (and the heritability of most mental traits). I agree, the situation is absurd and embarrassing for these fields. But this is what happened. I would like to say again, please do read the book. There were times when I was outraged by a position, to the point where I insult a person who is writing in good faith (as you have just done); this is usually a sign that I am reasoning backwards and am defending a position out of emotional attachment rather than trying to understand what is true. I would suggest this may be happening to you now. One thing to keep in mind is just because something is true doesn't make it good. You can preserve your moral outrage even as your descriptive beliefs change.
