Have good intentions, over-parenting and the decline in unsupervised play led to the emergence of modern identity politics and hypersensitivity? In this book, free speech campaigner Greg Lukianoff and social psychologist Jonathan Haidt investigate a new cultural phenomenon of "safetyism", beginning on American college campuses in 2014 and spreading throughout academic institutions in the English-speaking world.

Looking at the consequences of paranoid parenting, the increase in anxiety and depression amongst students and the rise of new ideas about justice, Lukianoff and Haidt argue that well-intended but misguided attempts to protect young people are damaging their development and mental health, the functioning of educational systems and even democracy itself.
