The Republican Brain

The Republican Brain: The Science of Why They Deny Science — and Reality  is a 2012 book about the psychological basis for many Republicans' rejection of mainstream scientific theories, as well as theories of economics and history, by the American journalist Chris Mooney.

Reception
The Financial Times gave the book a favorable review, describing it as an "intelligent, nuanced and persuasive account" of psychological differences in political behavior.

Alissa Quart, in a New York Times opinion piece, cited conservative writers Alex Berezow and Hank Campbell who equated Mooney's argument with eugenics. It was criticized by American conservative Jonah Goldberg, who tried to associate it with "conservative phrenology". Mooney responded, stating that Goldberg had mispresented his book in several respects. Mooney also stated that Goldberg exhibited "precisely the traits he seeks to deny: ideological defensiveness, a lack of nuance, and a deeply unwarranted and overconfident sense of certainty". Mooney later rebutted a similar criticism by Andrew Ferguson and stated that Ferguson dismissed science himself while attacking the book.

Paul Krugman wrote in The New York Times that Mooney makes a good point: the personality traits associated with modern conservatism, particularly a lack of openness, make the modern Republican Party hostile to the idea of objective inquiry.
