In this fascinating dialogue Dr. Haidt and Dr. Shermer discuss what has been going wrong on many college campuses in the last few years. Speakers are shouted down. Students and professors say they are walking on eggshells and are afraid to speak honestly. Rates of anxiety, depression, and suicide are rising—on campus as well as nationally. How did this happen? In his new book Haidt has teamed up with First Amendment expert Greg Lukianoff to show how the new problems on campus have their origins in three terrible ideas that have become increasingly woven into American childhood and education: What doesn’t kill you makes you weaker; always trust your feelings; and life is a battle between good people and evil people. These three Great Untruths contradict basic psychological principles about well-being and ancient wisdom from many cultures. Embracing these untruths—and the resulting culture of safetyism—interferes with young people’s social, emotional, and intellectual development. It makes it harder for them to become autonomous adults who are able to navigate the bumpy road of life. They explore changes in childhood such as the rise of fearful parenting, the decline of unsupervised, child-directed play, and the new world of social media that has engulfed teenagers in the last decade. They examine changes on campus, including the corporatization of universities and the emergence of new ideas about identity and justice. They situate the conflicts on campus within the context of America’s rapidly rising political polarization and dysfunction. Dr. Jonathan Haidt is Professor of Ethical Leadership at New York University’s Stern School of Business. He is a social psychologist whose field is moral psychology. He is the author of The Happiness Hypothesis: Finding Modern Truth in Ancient Wisdom and The Righteous Mind: Why Good People are Divided by Politics and Religion.
