Political censorship feels acceptable when ideas seem harmful and false

Abstract

People seem willing to censor disagreeable political and moral ideas. Five studies explore why people engage in political censorship and test a potential route to decreasing censorship. While Americans report being generally supportive of free speech and against censorship (Study 1), we find that people censor material that seems harmful and false (Study 2), which are often ideas from political opponents (Study 3). Building on work demonstrating the perceived truth of harmful experiences (i.e., experiences of victimization), we test an experience‐sharing intervention to reduce censorship. Among college students, the intervention indirectly decreased students' willingness to censor controversial campus speakers' ideas, through reducing beliefs that these speakers were sharing harmful and false ideas related to gun policy (Study 4). We also find benefits of sharing harmful experiences related to the abortion debate. Americans were less willing to censor and report the social media posts of opponents who base their views on experiences of victimization rather than scientific findings (Study 5).
