Michal Shermer and Jesse Singal discuss: how social scientists determine causality • Primeworld: cognitive priming and how it works (and doesn’t work) • The Malcolm Gladwell-effect (named after the 10,000-hour effect, by Anders Ericsson) • the self-esteem and self-help personal-empowerment movements • power posing and positive psychology • New Age self-help movements • Grit (stick-to-itiveness) (Darwin’s “dogged as does it.”) • Persistence is task specific and context dependent • Big 5 personality as determiners: Grit = Conscientiousness • Implicit Association Test and racism, misogyny, and bigotry • the replication crisis, what caused it, and what to do about it • choice architecture and the nudging of human behavior • race, gender, class, I.Q. and other radioactive topics in group differences • free will and determinism • nature/nurture and how lives turn out • abortion • and U.S. foreign policy.
