After being introduced to a series of campus controversies over the last few years involving jargon like “safe spaces” and “microaggressions,” it seems the country is wondering what exactly is going on at its universities. So much so, there is a market for two books to be released on the same day that try to provide an explanation.

In one of these books, The Coddling of the American Mind, Greg Lukianoff of the Foundation for Individual Rights in Education and social psychologist Jonathan Haidt of NYU’s Stern School of Business, expand upon their 2015 piece of the same name, published in the Atlantic, which attributes the recent trend of campus illiberalism to the psychological makeup of students: With a prioritization of mental health, universities are insulating students from ideas that challenge their world view.
