Prior research has shown that reading biased media content (e.g., Wikipedia articles) can increase recipients' hindsight bias. It remained unclear, however, which features of the biased texts led to such an increase. We examined this question in a longitudinal experimental study ( = 190). Specifically, we tested whether repeated exposure to already known information (H₁), a more coherent presentation of the information (H₂), or the presentation of novel information (H₃) affected readers' hindsight impressions of likelihood, inevitability, and foreseeability. To this end, participants initially learned about an event by reading several short news, and, 1 week later, received one of several summarizing texts, which systematically varied in the information contained. We found empirical support for the unique effect of mere repeated exposure and receiving novel information. Since media coverage of meaningful events is usually highly repetitive but also often comprising novel information, our findings contribute to a better understanding of how hindsight bias may publicly persist or even increase over time.

先前的研究表明，阅读有偏见的媒体内容（例如，维基百科文章）会增加接收者的后见之明偏差。然而，不清楚是什么特征的偏见文本导致了这种增加。我们在一项纵向实验研究中研究了这个问题（n=190）。具体来说，我们测试了重复接触已经知道的信息（H₁）、更连贯地呈现信息（H₂）或呈现新信息（H₃）是否会影响读者对可能性、必然性和可预测性的后见之明印象。为此，参与者最初通过阅读几条简短的新闻来了解一个事件，一周后，他们收到了几篇总结性文本中的一篇，这些文本在包含的信息上系统地有所不同。我们发现，仅仅重复接触和接收新信息具有独特的影响。由于对有意义事件的媒体报道通常是高度重复的，但也经常包含新信息，因此我们的发现有助于更好地理解后见之明偏差如何可能随着时间的推移公开持续存在，甚至增加。（PsycInfo 数据库记录（c）2021 APA，保留所有权利）。
