Facebook's internal research found that Instagram, which it acquired in 2012 for $1 billion, makes eating disorders and thoughts of suicide worse in teenage girls, whistleblower Frances Haugen said in a "60 Minutes" interview on Sunday.
Haugen, a former product manager at Facebook, gathered internal documents as she grew frustrated by the company's prioritization of growth and user engagement over its negative impacts, The Wall Street Journal reported.
According to internal studies retrieved by Haugen, Facebook found that 13.5% of teen girls say Instagram makes thoughts of suicide worse, and 17% of teen girls say Instagram makes eating disorders worse.
"And what's super tragic is Facebook's own research says as these young women begin to consume this eating disorder content, they get more and more depressed. It actually makes them use the app more," Haugen said. "They end up in this feedback cycle where they hate their bodies more and more."
Facebook's own research says that Instagram is "distinctly worse than other forms of social media" and harms teenagers, Haugen said.
