It is now widely accepted that an epidemic of mental illness began among American teens in the early 2010s. What caused it? Many commentators point to events in the USA around that time, such as a particularly horrific school shooting in 2012. But if the epidemic started in many nations at the same time, then such country-specific theories would not work. We’d need to find a global event or trend, and the 2008 Global Financial Crisis doesn’t match the timing at all, as Jean Twenge and I have shown.
In our 2018 book The Coddling of the American Mind, Greg Lukianoff and I presented evidence that the same trends were happening in Canada and the United Kingdom—not just the rise in depression and anxiety, but also the overprotection of children, the rise of “safetyism,” and the shouting down of speakers on university campuses when students deemed the speaker to be “harmful.” It seemed that all the Anglo nations were setting up their children for failure in the same ways at the same time.
