We have long been moving into a world of increased convenience and pleasure, at the cost of strong and local tight-knit communities — which has led to profound isolation and loneliness. In this essay, I argue that we must find ways to provide children with vibrant

The teen mental illness crisis is not just concentrated in the United States. I explain how and why it hits Gen Z girls across the Anglosphere around the same time and in the same way. My first of three posts w/ @JonHaidt , Part 1: The Anglosphere.

@Scientific_Bird Four things here: 1. These trends are not split up by sex. Our argument is sex-specific. 2. the WHO GHE (Which is the dataset being used here) underestimates known rates of suicide. So, even the U.S. data after 2010 is not correct here. (and it is the case for many nations

Nordic teens are struggling very much like Anglo teens. I have looked at 10 countries, and they all show the same pattern: Teenage girls are struggling more than all other age groups and much more than they were a decade ago. @JonHaidt & @ToMpy1337

@EricLevitz An important part of the story, I believe, is we need to go back further. I have data from Australia, which shows the same trends. But as you can see, it's not reverting to an older mean-- the 80s were particularly bad, for different reasons than they are now.

It seems like we are using a single study of New Jersey Hospitals to speculate that most of the rise is self-harm among girls in the United States or, even, in other countries has nothing to do with actual increases? There is so

It is time for schools to go phone-free. Smartphones undermine attention, learning, and relationships. It's like we give each child a portable soda dispenser 24 hrs/day, 7 days/wk. Let's give them 7 hrs of healthy childhood back. @JonHaidt

@JonHaidt And it's not only self-reported rises in poor mental health. Gen Z girls in the U.S., UK, Canada, Australia, and New Zealand have higher rates of suicide than any prior generation of girls at that age for which we have data for. @JonHaidt

@cjsewall9 @JonHaidt Oh yes. I actually cite this in the article. The pediatrics article is covering all kids ages 3-17. But we can get some parsing of the trends by age/sex. In 2009, there was an estimated 82,887 girls (ages 3-17) hospitalized for mental health conditions. By 2019, it is 123,342.

@post_liberal @JonHaidt Yes! There are discrepancies in Denmark between reports of anxiety and depression and self-harm rates (the self-harm study you cite goes up to 2016, so I do not know what has happened since). I address this in the post. Let me know if you have thoughts about the discrepancy!

One theory that might explain *part* of the teen mental health crisis is that we're reverting to the long-run mean, after a period of exceptionally low levels of adolescent mental distress (tho the suicide rate among girls specifically is at all time-high)

@JayMan471 @Scientific_Bird It’s true that it is the most objective measure but that does not mean that other measures should be discounted. If we dismiss other measures because they are imprecise we miss an enormous amount of information about sub-populations. Self harm, like suicide, is also a

@cjsewall9 @JonHaidt The issue is that the CDC does not provide yearly data for the 10-14 year-olds for hospitalizations. The closest I can get for you is 2013 and 2017, which is a rise of 56.8%. I have more data point for ED visits. So from 2012 to 2019 for 10-14, the % increase was 91.3%. Just

@JonHaidt And one of the reason people disagree on the international scope of the problem is that they are relying on a dataset that systematically underestimates rates of youth mental illness in countries that have robust national mental health data.

@sergiotpinto @paulnovosad @mikekofoed Hi Sergio, I am deleting the previous tweet because it was not fully accurate. The trends in the OWID graphs you have above are *not* relying on the GBD. OWID relies on WHO estimates, which rely in part on the GBD (But only for countries without good death registration data).

@StefanFSchubert @JonHaidt @SteveStuWill Agreed, I wanted to be consistent with my other graphs by including the relative increase. I do not make the case that self-harm rates in Sweden have increased in a way that supports our hypothesis. But the rise during COVID, to me, seems evident.

@cjsewall9 @JonHaidt Just to respond to the first point here. My approach has been to average a few years before 2010. The CDC does not provide rates for the 10-14 year-olds in 2009. So I averaged 2007-08 together, to try to find a relatively stable base rate that can look at pre- and post- 2010.
