A Plea for Cognitive Tolerance
Pinker makes the case:
Dangerous ideas are likely to confront us at an increasing rate and we are ill equipped to deal with them. When done right, science (together with other truth-seeking institutions, such as history and journalism) characterizes the world as it is, without regard to whose feelings get hurt. Science in particular has always been a source of heresy, and today the galloping advances in touchy areas like genetics, evolution and the environment sciences are bound to throw unsettling possibilities at us. Moreover, the rise of globalization and the Internet are allowing heretics to find one another and work around the barriers of traditional media and academic journals. I also suspect that a change in generational sensibilities will hasten the process. The term “political correctness” captures the 1960s conception of moral rectitude that we baby boomers brought with us as we took over academia, journalism and government. In my experience, today’s students — black and white, male and female — are bewildered by the idea, common among their parents, that certain scientific opinions are immoral or certain questions too hot to handle.
