If you think the debate over Facebook’s efficacy among teens is overblown, you are mistaken. A new study led by the University of Washington’s Tyler Preston and the Associated Press’ Gary Kamiya finds that younger users are more likely to ignore or avoid Facebook because the social network is frustrating and confusing. According to the study, 66 percent of high school students and 61 percent of middle schoolers say that Facebook makes their lives too difficult. More than half are not able to figure out why their posts don’t show up as they expect them to on the News Feed. And perhaps most troubling, 55 percent of middle schoolers say they often feel “paranoid” about their interactions with Facebook, assuming that the platform is censoring their posts or ignoring things they posted. It’s no surprise that social media has become an increasingly polarizing medium. But teenage users don’t have the same access to data as older, presumably wiser, social media users have. Teenagers trust a word of Facebook when older users might be less credulous about posts and conversations between acquaintances. That might help explain the anxiety of sharing personal information online.
