Leiter Reports: "It's an odd situation in America today: on one side, we have hordes of ignorant yahoos--driven by various forms of delusion and without any regard for reason or evidence--denying the foundation of modern biology, the theory of evolution by natural selection; on the other side, we have various social scientists, some ill-informed law professors, and a handful of biologists--driven by various forms of intellectual imperialism and with only slightly more regard for reason and evidence--advancing selectionist ('Darwinian') explanations for a wide range of human behaviors, even though these explanations systematically fail to meet the evidential standards well-established in the biological sciences."
