**'Excellent, their advice is sound . . . liberal parents, in particular, should read it' *Financial TimesThe New York Times* bestsellerWhat doesn't kill you makes you weakerAlways trust your feelingsLife is a battle between good people and evil people**These three Great Untruths contradict basic psychological principles about well-being, as well as ancient wisdom from many cultures. And yet they have become increasingly woven into education, culminating in a stifling culture of "safetyism" that began on American college campuses and is spreading throughout academic institutions in the English-speaking world.In this book, free speech campaigner Greg Lukianoff and social psychologist Jonathan Haidt investigate six trends that caused the spread of these untruths, from the decline of unsupervised play to the corporatization of universities and the rise of new ideas about identity and justice.Lukianoff and Haidt argue that well-intended but misguided attempts to protect young people can hamper their development, with devastating consequences for them, for the educational system and for democracy itself.
