But then you have to explain to the rest of us who is that man? Well, I'll do it. He was an American psychologist. The one who was like "genetics was solely responsible for intelligence". Geneticism (基因主义), you know...
Yeah he is a differential psychologist and psychometrician, but his claims were all psychometrically sound and reasonable. I am not sure why you criticized him as a geneticist. He just told you the truth.
Btw I never said intelligence was 100% genetic. I said it was mostly genetic, which was in line with what arthur jensen said who actually never said intelligence was 100% genetic.
This scholar indeed has contributed a lot to psychometrics and differential psychology. I don't think you should treat him as if he was no one who should be taken seriously.
