A Scientific American feature article from 1998, Linda Gottfredson on g. Quote:

The debate over intelligence and intelligence testing focuses on the question of whether it is useful or meaningful to evaluate people according to a single major dimension of cognitive competence. Is there indeed a general mental ability we commonly call “intelligence,” and is it important in the practical affairs of life? The answer, based on decades of intelligence research, is an unequivocal yes.

But, what if the fact that I don’t have an extremely high IQ makes me feel bad? Then I’ll dismiss all that research and ignore it. Who needs science that doesn’t make me feel better about myself?
