Enhancing Integrity: TikTok's Footnotes Feature and the Challenge of Misinformation

TikTok is going to be testing a new crowd-sourced fact-checking system called Footnotes. It’s seems similar to the Community Notes systems already in use on other social media, such as X and Facebook.

TikTok is also keeping its current fact-checking systems in place. The way these community systems generally work is, say someone makes a post stating "whales are the biggest fish out there." Another user could add a note saying "actually, whales are mammals, and here's a source with more information."

Marketplace’s Stephanie Hughes spoke with Vanderbilt psychology professor Lisa Fazio about why this model of "citizen fact-checking" is catching on.
