Featuring the work of Jonathan Haidt.

The environment in which kids grow up today is hostile to human development.

“Something went suddenly and horribly wrong for adolescents in the early 2010s. By now you’ve likely seen the statistics: Rates of depression and anxiety in the United States—fairly stable in the 2000s—rose by more than 50 percent in many studies from 2010 to 2019. The suicide rate rose 48 percent for adolescents ages 10 to 19. For girls ages 10 to 14, it rose 131 percent.

The problem was not limited to the U.S.: Similar patterns emerged around the same time in Canada, the U.K., Australia, New Zealand, the Nordic countries, and beyond. By a variety of measures and in a variety of countries, the members of Generation Z (born in and after 1996) are suffering from anxiety, depression, self-harm, and related disorders at levels higher than any other generation for which we have data.”

The decline in mental health is just one of many signs that something went awry.
