How little we know what we most need to know. This is an exceptionally striking fact about the most promising new field to arise in our time, evolutionary psychology, led by Harvard psychology professor Steven Pinker and our own Jonathan Haidt, author of "The Happiness Hypothesis." Its emphasis on natural selection serves as a valuable sanity check on the otherwise crushing power of political prejudice in the social sciences (I use the term loosely), especially through its politically incorrect discovery of the evolutionary basis of many sexual inequalities.
