Another smart lecture by psychologist Jonathan Haidt whose “research indicates that morality is a social construction which has evolved out of raw materials provided by five (or more) innate “psychological” foundations: Harm, Fairness, Ingroup, Authority, and Purity. Highly educated liberals generally rely upon and endorse only the first two foundations, whereas people who are more conservative, more religious, or of lower social class usually rely upon and endorse all five foundations.” (part 1 below; part 2; Q&A 1; Q&A 2)
