If feminists continue to reject the mounting evidence from the biological sciences (e.g., genetics, behavioral genetics, neurophysiology, endocrinology, evolutionary biology) and the social sciences (e.g., cognitive psychology, neurolinguistics, artificial intelligence) with regard to the biological underpinnings of human behavior, they back themselves into an embarrassingly uninformed corner. In order to understand human nature and human behavior, all possible sources of information should be taken into account, not just those that exert an ideological appeal to us.
