Steven Pinker is a psychologist who writes on politics. His theories are interesting but are framed too universally to be valid

From the sister blog:

Psychology is a universal science of human nature, whereas political science is centered on the study of particular historical events and trends. Perhaps it is unsurprising, then, that when a psychologist looks at politics, he presents ideas that are thought-provoking but are too general to quite work. This is fine; political scientists can then take such ideas and try to adapt them more closely to particular circumstances.

The psychologist I’m thinking about here is Steven Pinker . . .
