This is a discussion between Mike Masnick of Techdirt and Professor Andy Przybylski from the University of Oxford about research Przybylski has done about the effects of social media on children, mental health and video games and the effects of Facebook on well-being.

In short, he didn't find a lot of evidence supporting the claims that social media and video games had a negative impact on people's well-being.
It is a good conversation to listen to and consider in the light of the increased scrutiny that the tech industry is under. The tech industry has escaped scrutiny for too long but there are times when bad regulation is worse than no regulation. There is a danger of the pendulum swinging too far in the other direction.
I want to see better regulations drafted when considering the best available evidence. A major problem is that the data required to perform this research is locked within servers owned by the companies who aren't really incentivised to allow academics to use it, especially if they feel it could impact them negatively. There is need of a transparent process to give researchers the access they need while also protecting the sensitive data that the companies should be protecting.
