Most fake photos are pretty harmless. People often create them to get a laugh or a lot of likes on social media. Maybe they want to trick friends into thinking they own a 200-pound cat or that Taylor Swift came to their birthday party.
But others do it for a more harmful purpose. For example, many fake photos are meant to make political leaders look bad. The goal is to spread lies in order to change the way people think or how they vote.
“With the right image and the right headline, you can make people believe all sorts of things,” says John Silva. He works for the News Literacy Project, a group that helps students learn to find reliable news sources.
