Across social media, posts can fly up faster than most fact-checkers can handle, andthey are often an unpredictable mix of true, fake, and out of context. — 36 How doyou know what to trust and what not to share? Here are some basic tools everyone shoulduse when consuming breaking news online. 37 Think about who would benefit from spreading confusing informationduring a news event. During elections, for example, look out for conflicting informationand baseless accusations that may benefit one political party or candidate. Of course, not allmisinformation is serious. Some is created just for fun or to troll (恶搞) people, so be asskeptical of silly stories as serious ones.Slow down while reading or watching. Social media is built for things to go viral, forusers to quickly share before they are even done reading the words. No matter howshocking, enlightening or annoying a TikTok or YouTube video is, you must wait beforeis confirmed and accurate.
