The cognitive scientist Steven Pinker was a graduate student at Harvard in the 1970s. In his 2002 book The Blank Slate: The Modern Denial of Human Nature, Pinker describes the ways scientists betrayed the values of science to maintain loyalty to the progressive movement. Scientists became “moral exhibitionists” in the lecture hall as they demonized fellow scientists and urged their students to evaluate ideas not for their truth but for their consistency with progressive ideals such as racial and gender equality.14
