This article is very recent: https://www.theguardian.com/technology/2017/dec/15/facebook-mental-health-psychology-social-media A few bits of it: "Facebook has acknowledged that social media use can be bad for users’ mental health, a sign the company is feeling pressure from a growing chorus of critics raising alarms about the platform’s effect on society." "The company’s public recognition of some of its platform’s detrimental effects came days after a former Facebook executive made headlines with a speech slamming the corporation, saying: “The short-term, dopamine-driven feedback loops that we have created are destroying how society works. No civil discourse, no cooperation, misinformation, mistruth.”" "Studies have repeatedly found that Facebook, Twitter and other social media sites can damage the emotional wellbeing of heavy users, particularly younger people." My take? Of course FB, social media in general causes havoc in us. They can be used for good stuff however, but let's face it, most people don't. IMO, it's a very serious problem.
