alt Hacker NewsSocial media being bad for mental health in childhood is one of the most robust theories I've ever seen for these kind of society-wide problems. You can peruse the After Babel Substack for the evidence if you're not convinced, but Jonathan Haidt has consistently done incredible work here.
All due respect, I do not think the substack of one of the world's leading proponents of the theory that screen time is harmful is a good source for evidence that runs contrary to that narrative.
Here's Nature reviewing his book:
> Hundreds of researchers, myself included, have searched for the kind of large effects suggested by Haidt. Our efforts have produced a mix of no, small and mixed associations. Most data are correlative. When associations over time are found, they suggest not that social-media use predicts or causes depression, but that young people who already have mental-health problems use such platforms more often or in different ways from their healthy peers
> These are not just our data or my opinion. Several meta-analyses and systematic reviews converge on the same message. An analysis done in 72 countries shows no consistent or measurable associations between well-being and the roll-out of social media globally. Moreover, findings from the Adolescent Brain Cognitive Development study, the largest long-term study of adolescent brain development in the United States, has found no evidence of drastic changes associated with digital-technology use. Haidt, a social psychologist at New York University, is a gifted storyteller, but his tale is currently one searching for evidence.
