The Internet provides a great deal of content on science-related issues. This leads to a multitude of possibilities to collect information, but may also cause difficulties in identifying relevant and credible pieces of content and coming to an informed stance. Against this background, this project examines how laypersons deal with science-related information in Web 2.0 applications such as blogs. Based on models of persuasion (e.g., Petty & Cacioppo, 1986) and findings of the first two project phases, the studies address remaining questions regarding attitude formation and the influence of reader comments and ratings (due to the increased importance of user-generated feedback in Web 2.0 settings, see Walther & Jang, 2012). In particular, we will investigate under which circumstances conflicting evidence and the complexity of current scientific debates are represented in readers' attitudes. For this purpose, the assessment will include potential ambivalence and the certainty of attitudes (Wagner, Brinol & Petty, 2012). In this context, two experimental studies investigate the influence of message complexity (message sidedness, with a comparison of two-sided framing and actual two-sidedness); users' need for cognition and epistemological beliefs are included as moderating variables. Two further studies examine the effects of user comments providing counterarguments against the message of the main article. These are either comments with personal experiences (exemplars), which may offer further information on the topic but may also lead to biased perceptions of the opinion climate, or comments referring to empirical evidence. The influence of these two types of comments is tested in combination with helpfulness ratings given by other users. Based on these findings, a recently suggested model on selection and processing of online science information (Krämer & Winter, submitted) will be extended and tested in two experiments with a new exemplary topic (under consideration of different reading goals and with an additional assessment of behavioral intentions).

互联网提供了大量有关科学相关问题的内容。这带来了收集信息的多种可能性，但也可能导致识别相关且可信的内容以及形成知情立场的困难。在此背景下，该项目研究了外行如何处理 Web 2.0 应用程序（例如博客）中的科学相关信息。基于说服模型（例如 Petty & Cacioppo，1986）和前两个项目阶段的发现，这些研究解决了有关态度形成以及读者评论和评级影响的剩余问题（由于 Web 2.0 设置中用户生成的反馈的重要性日益增加，请参见 Walther & Jang，2012）。特别是，我们将调查在何种情况下，相互矛盾的证据和当前科学辩论的复杂性会体现在读者的态度中。为此，评估将包括潜在的矛盾心理和态度的确定性（Wagner、Brinol & Petty，2012）。在此背景下，两项实验研究调查了消息复杂性的影响（消息侧面性，比较两侧框架和实际两侧性）；用户的认知需求和认识论信仰被纳入调节变量。两项进一步的研究考察了用户评论对主要文章信息提出反驳的影响。这些评论要么是带有个人经历（范例）的评论，可能提供有关该主题的更多信息，但也可能导致对舆论氛围的偏见；要么是引用经验证据的评论。结合其他用户给出的有用性评级来测试这两种类型评论的影响力。基于这些发现，最近建议的在线科学信息选择和处理模型（Krämer & Winter，已提交）将在两个实验中以新的示例性主题进行扩展和测试（考虑不同的阅读目标并对行为意图进行额外评估）。
