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.
There are a lot of problems with the way these platforms treat adults too. I think an age gate is the wrong solution and in many ways it doesn't go far enough.
Here's his rebuttal to that article: https://www.afterbabel.com/p/phone-based-childhood-cause-epi....
I think you'd struggle to find someone more earnestly trying to get an unbiased understanding of the reality of this topic.
Why did one study in Spain find an association with the rollout of high speed internet, but a much larger international study specifically looking at Facebook usage did not? Seems like that one should even more directly measure what’s alleged to be occurring.
