Steven Pinker: "We have an unprecedented wealth of data from social psychology, ethnography, behavioral economics, criminology, behavioral genetics, cognitive neuroscience, and so on, that could inform (though of course, not dictate) policies in law, political decision-making, welfare, and so on. But they are seldom brought to bear on the issues... Since all policy decisions presuppose some hypothesis about human nature, wouldn't it make sense to bring the presuppositions into the open so they can be scrutinized in the light of our best data?"
