Frances Haugen, the former Facebook data scientist revealed her identity in a televised interview on Sunday night. She revealed how algorithms affect what we see on social media, and worked at Facebook on a team focused on the spread of election-related misinformation. Frances Haugen says Facebook has misrepresented the prevalence of hate speech on the platform, hid reports on Instagram's impact on teen girls' mental health and more.

The company points to its investment in monitoring for harmful content and disputes the way its research on teen's mental health has been reported in the media. Frances Haugen was interviewed by Scott Pelley for a CBS News "60 Minutes" interview that aired on Sunday.

She spent two years at Facebook working on a team focused on figuring out how election-related misinformation spreads. She previously worked at Google and Pinterest. Over time, she became disillusioned. She felt like her team was understaffed, and that Facebook wasn't taking seriously how its platform was affecting societies around the world. Eventually, Facebook shut down her team altogether. Weeks later, the Capitol riots happened.

Frances Haugen says Facebook underplayed its role helping organizers plan the riots. She kept noticing that Facebook's public statements didn't match what the company's own research was saying. She had a crisis of conscience. And she decided she had a moral duty to obtain and leak thousands of internal Facebook research to the Securities and Exchange Commission and the media.
