There is a lot of statistics about how social media causes depression/unhappiness in the article. But I didn't see sources, and from what I can tell (without looking at the studies) it's just a correlation. I do believe social media impacts depression rates and creates some unhappiness, but the claims in the article seem unsupported. Surely, depressed kids would have spent more time alone in all ages, hanging out in their room, watching TV, maybe reading. Honestly, even if social media made you HAPPIER, I'd expect unhappy eight graders to spend more time on social media than those with a sunnier disposition.
