A field experiment examined social approval in the form of Twitter “Likes” on individuals’ perceptions after retweeting a fictitious news story about a politician. The study incorporated research about feedback effects on self-perception online, partisan bias, and negativity principles. Participants read or retweeted a (verifiably false) news story via social media, and researchers appended systematic increments of Likes to the retweets. A baseline hypothesis test found no effect on perceptions due to retweeting versus simply reading a news story. Results supported a predicted three-way interaction effect between positive versus negative news story, political congruence with participants’ political party identification, and the reception of 0–22 Likes on perceptions of the politician. More Likes magnified negative perceptions of politicians, from fictitious news, when news stories were negative and focused on politicians from one’s opposite political party.

社交媒体消息共享后社交认可对感知的影响适用于假新闻

一项实地实验以推特“赞”的形式检查了社会对个人在转发关于政治家的虚构新闻故事后的看法的认可。该研究纳入了关于反馈对在线自我认知、党派偏见和消极原则的影响的研究。参与者通过社交媒体阅读或转发（可证实为虚假的）新闻故事，研究人员在转发后系统地增加了点赞数。基线假设检验发现，转推与简单阅读新闻故事相比，对认知没有影响。结果支持了正面与负面新闻故事之间的预测三向交互效应，政治一致性与参与者的政党认同，以及对政治家看法的 0-22 个赞的接收。更多点赞放大了对政客的负面看法，
