A consistent finding in fake news research is that people are more likely to believe content in favor of their political views. Unclear, however, is whether this political bias is moderated by contextual effects, such as politicians sharing content on their social media accounts. The present study investigated how both message content and sharer affect views of political misinformation. Participants (N = 164) evaluated eight news messages. Message content (pro-left/pro-right misinformation) and sharer (left-wing/right-wing/unknown politician) were manipulated within subjects. As expected, participants agreed more with concordant misinformation (aligned with their political orientation) and perceived it as more accurate than discordant misinformation. There was an additional, smaller effect of politician: Participants agreed more with discordant misinformation when shared by a politician representing their political viewpoint than when shared by others. Furthermore, left-oriented participants' agreement with concordant misinformation was hardly affected by message sharer, whereas right-oriented participants' agreement with concordant misinformation was-unexpectedly-positively affected by the left-wing politician. Irrespective of their political orientation, participants perceived misinformation from the left-wing politician as more accurate than misinformation from other politicians. Our findings suggest that both message content and sharer affect views of misinformation and interact in doing so, which is important for designing interventions on recognizing misinformation.

理清消息内容和消息分享者对学生对政治错误信息的看法的影响。

假新闻研究的一个一致发现是，人们更有可能相信有利于他们政治观点的内容。然而，尚不清楚这种政治偏见是否会受到情境效应的调节，例如政客在社交媒体帐户上分享内容。本研究调查了消息内容和分享者如何影响对政治错误信息的看法。参与者 (N = 164) 评估了八条新闻消息。消息内容（支持左翼/支持右翼的错误信息）和分享者（左翼/右翼/未知政治家）在主题内被操纵。正如预期的那样，参与者更同意一致的错误信息（与其政治倾向一致），并认为它比不一致的错误信息更准确。政治家还有一个额外的、较小的影响：当代表他们的政治观点的政治家分享时，参与者比其他人分享时更同意不一致的错误信息。此外，左翼参与者对一致错误信息的同意几乎不受信息共享者的影响，而右翼参与者对一致错误信息的同意却意外地受到左翼政客的积极影响。无论政治倾向如何，参与者都认为左翼政客的错误信息比其他政客的错误信息更准确。我们的研究结果表明，消息内容和分享者都会影响对错误信息的看法，并在此过程中相互作用，这对于设计识别错误信息的干预措施非常重要。（PsycInfo 数据库记录 (c) 2023 APA，保留所有权利）。
