Every time Haidt comes up, I do go through the post and do another literature search on social media effects.<p>The most notable thing about this post is the MHQ figures. However, you might note that the difference in age of smartphone use moves a person by at most one bucket. Given that he is suggesting a ban on smartphones and/or social media, I would expect some more catastrophic effect.<p>In terms of the literature review, this time I read through [0]. It also finds small but significant effects on anxiety and depression, but finds no significant effects on overall measures of well-being. This is because social media also seems to have some positive effects on some other measures of well-being. This meta analysis also finds that age does not seem to change the effects of social media. On longitudinal studies, it seems like social well-being does decrease social media use, but anxiety and depression to not increase social media use. Also, social media use doesn't seem to cause anxiety and depression here, so there is probably some third factor causing anxiety, depression, and social media use which causes this correlation.<p>Also interesting is that internationally the effects are neutral, and in the US, the effects are neutral, but in Europe they are negative, while in Asia they are positive. IDK why, but it doesn't really support his hypothesis that social media has some sort of catastrophic impact worth banning.<p>[0]: <a href="https://gwern.net/doc/sociology/technology/2022-hancock.pdf" rel="nofollow">https://gwern.net/doc/sociology/technology/2022-hancock.pdf</a>
