Janathan Haidt, writing at his new Substack:

In conclusion, I believe that Greg Lukianoff was exactly right in the diagnosis he shared with me in 2014. Many young people had suddenly—around 2013—embraced three great untruths:

They came to believe that they were fragile and would be harmed by books, speakers, and words, which they learned were forms of violence (Great Untruth #1).

They came to believe that their emotions—especially their anxieties—were reliable guides to reality (Great Untruth #2).

They came to see society as comprised of victims and oppressors—good people and bad people (Great Untruth #3).

Liberals embraced these beliefs more than conservatives. Young liberal women adopted them more than any other group due to their heavier use of social media and their participation in online communities that developed new disempowering ideas. These cognitive distortions then caused them to become more anxious and depressed than other groups. Just as Greg had feared, many universities and progressive institutions embraced these three untruths and implemented programs that performed reverse CBT on young people, in violation of their duty to care for them and educate them.
