Nowhere? I suspect few people actually read the report [1]. They asked teen girls (and boys) how Instagram made them feel. The most common response for girls was "no effect" 43%, followed by "somewhat better" 29%, then "somewhat worse" at 18%, then "much better" at 8%, and lastly "much worse" at 3%. The media conspicuously ignored that substantially more girls felt that Instagram made them feel better than worse.

I don't trust any research Facebook releases about the impact of their own platform and would take such with a grain of salt. There is no incentive for them to ever release negative results.

You might not trust them, but the quote is taken out of context by the media and whenever it gets regurgitated on the internet. It's used as some kind of a "See, I knew I was correct in disliking them!" idea.

That's easily spotted if they preregister their experiments.

They didn't release these results. It was leaked.

That "much worse" at 3% was represented by a single reply.

When i read about the study my biggest surprise was how poorly it was. A poll with 40 people is so pointless that I don't understand why they didn't hire professionals to do a real survey.
