Every day, countless bits of misinformation are shared on social media. Misinformation comes in many forms. It could be a fake news article posted on Twitter or a phony photo on Instagram. It might also be a video on YouTube that presents false information as fact.
Often people spread hoaxes for fun or to get likes or shares. But sometimes, misinformation is about important topics, like the environment or politics. The goal of these viral hoaxes is to change people’s opinions—and even affect how people vote.
Experts say false information is most effective when it sparks laughter, anger, or sadness.
“If a post or picture or video makes the viewer feel very strongly, they are more likely to share it,” says Sierra Filucci of Common Sense Media. That organization aims to help kids spot false information online.
And, Filucci says, the more a video or post has been liked or shared, the more likely others are to believe it—and to share it without checking the facts.
