Reception and production of scientific information in Wikipedia: The influence of hindsight bias and social categorization

当外行人在互联网上搜索信息时，他们经常会遇到各种各样的科学发现，这些发现往往是不一致的，因此给接受者带来了挑战。我们提出两个过程-后见之明偏见和社会分类-有助于处理相互矛盾的证据。当人们事后关注与结果一致的信息时，社会分类导致人们倾向于与自己的态度（以及自己的内部群体）一致的信息，以及态度不一致的信息的退化。然而，随着Web 2.0的发展，用户不仅可以阅读科学信息，还可以在Web上生成与科学相关的信息。因此，我们建议这两个过程同样应该被观察到网络内容的作者。该项目的目的是调查后见之明偏见和社会分类是否可以在在线百科全书维基百科的接受者和生产者中观察到。此外，我们将研究三种策略的有效性，这些策略可能会减少后见之明偏见以及社会分类的影响。我们希望这些结果能够补充之前关于接受相互矛盾的科学证据的发现，并进一步加深我们对个人和集体信息处理之间关系的理论理解。

When laypersons search the Internet for information they are frequently confronted with a variety of scientific findings, which are often inconsistent and thus provide a challenge for the recipient. We propose that two processes - the hindsight bias and social categorizations - facilitate the handling of conflicting evidence. While people in hindsight focus on outcome consistent information, social categorizations lead to a preference for information that is consistent with one's attitude (and one's in-group) as well as a degradation of attitude inconsistent information.Since the development of the Web 2.0, however, users may not only read scientific information but also produce science-related information on the Web. Therefore we propose that both processes should likewise be observed for authors of web contents. The aim of the project is to investigate whether a hindsight bias and social categorizations can be observed in recipients as well as pro-ducers of the online encyclopedia Wikipedia. Additionally we will examine the efficacy of three strategies that might reduce the hindsight bias as well as the effects of social categorizations. We expect the results to complement the previous findings regarding the reception of conflicting scien-tific evidence and to further our theoretical understanding of the relationship between individual and collective information processing.
