“To Greg, who had suffered from bouts of depression throughout his life, this seemed like a terrible approach. In seeking treatment for his depression, he—along with millions of others around the world—had found that cognitive behavioral therapy (CBT) was the most effective solution. CBT teaches you to notice when you are engaging in various “cognitive distortions,” such as “catastrophizing” (If I fail this quiz, I’ll fail the class and be kicked out of school, and then I’ll never get a job . . .) and “negative filtering” (only paying attention to negative feedback instead of noticing praise as well). These distorted and irrational thought patterns are hallmarks of depression and anxiety disorders. We are not saying that students are never in real physical danger, or that their claims about injustice are usually cognitive distortions. We are saying that even when students are reacting to real problems, they are more likely than previous generations to engage in thought patterns that make those problems seem more threatening, which makes them harder to solve. An important discovery by early CBT researchers was that if people learn to stop thinking this way, their depression and anxiety usually subside. For this reason, Greg was troubled when he noticed that some students’ reactions to speech on college campuses exhibited exactly the same distortions that he had learned to rebut in his own therapy. Where had students learned these bad mental habits? Wouldn’t these cognitive distortions make students more anxious and depressed?”
