Why the Mental Health of Liberal Girls Sank First and Fastest

There are at least two ways to explain why liberal girls became depressed faster than other groups at the exact time (around 2012) when teens traded in their flip phones for smartphones and the girls joined Instagram en masse. The first and simplest explanation is that liberal girls simply used social media more than any other group. Jean Twenge’s forthcoming book, Generations, is full of amazing graphs and insightful explanations of generational differences. In her chapter on Gen Z, she shows that liberal teen girls are by far the most likely to report that they spend five or more hours a day on social media (31% in recent years, compared to 22% for conservative girls, 18% for liberal boys, and just 13% for conservative boys). Being an ultra-heavy user means that you have less time available for everything else, including time “in real life” with your friends. Twenge shows in another graph that from the 1970s through the early 2000s, liberal girls spent more time with friends than conservative girls. But after 2010 their time with friends drops so fast that by 2016 they are spending less time with friends than are conservative girls. So part of the story may be that social media took over the lives of liberal girls more than any other group, and it is now clear that heavy use of social media damages mental health, especially during early puberty.

But I think there’s more going on here than the quantity of time on social media. Like Filipovic, Yglesias, Goldberg, and Lukianoff, I think there’s something about the messages liberal girls consume that is more damaging to mental health than those consumed by other groups…

…we have support for Filipovic’s “captain their own ship” concern, and for Lukianoff’s disempowerment concern: Gen Z has become more external in its locus of control, and Gen Z liberals (of both sexes) have become more self-derogating. They are more likely to agree that they “can’t do anything right.”…As Gen Z women became more progressive and more involved in political activism in the 2010s, it seems to have changed them psychologically.
