Mistakes, Overconfidence, and the Effect of Sharing on Detecting Lies
实验发现参与者难以识别谎言且过度自信,即使有激励也更可能分享谎言,而接收者更易相信分享的视频,导致谎言传播。
Mistakes and overconfidence in detecting lies could help lies spread. Participants in our experiments observe videos in which senders either tell the truth or lie, and are incentivized to distinguish between them. We find that participants fail to detect lies, but are overconfident about their ability to do so. We use these findings to study the determinants of sharing and its effect on lie detection, finding that even when incentivized to share truthful videos, participants are more likely to share lies. Moreover, the receivers are more likely to believe shared videos. Combined, the tendency to believe lies increases with sharing.
