Steven Pinker argues that critics have been overly swayed by politics and a fear of biological determinism, accusing among others Stephen Jay Gould and Richard Lewontin of being "radical scientists", whose stance on human nature is influenced by politics rather than science, while Lewontin, Steven Rose and Leon Kamin, who drew a distinction between the politics and history of an idea and its scientific validity, argue that sociobiology fails on scientific grounds. Gould grouped sociobiology with eugenics, criticizing both in his book "The Mismeasure of Man".
