The 2016 election was a watershed moment for the spread of misinformation online, so social networks have been exploring ideas to prevent the same from happening again in 2020. Twitter’s latest test: labeling “harmfully misleading” tweets by politicians.

NBC News first reported on the leaked test, which Twitter confirmed. With the new feature, misleading tweets would be labeled with a bright orange warning. Tweets from verified fact-checkers and journalists are then shown under the labeled tweet. It’s also possible Twitter would include corrections from other users participating in a new crowdsourced “community reports” feature akin to Wikipedia.
