Nonserious answering behavior increases noise and reduces experimental power; it is therefore one of the most important threats to the validity of online research. A simple way to address the problem is to ask respondents about the seriousness of their participation and to exclude self-declared nonserious participants from analysis. To validate this approach, a survey was conducted in the week prior to the German 2009 federal election to the Bundestag. Serious participants answered a number of attitudinal and behavioral questions in a more consistent and predictively valid manner than did nonserious participants. We therefore recommend routinely employing seriousness checks in online surveys to improve data validity.
不认真的回答行为会增加噪音并降低实验效力；因此，它是在线研究有效性的最重要威胁之一。解决这个问题的一个简单方法是询问受访者他们参与的认真程度，并将自我宣称不认真的参与者排除在分析之外。为了验证这种方法，我们在德国 2009 年联邦选举前一周进行了一项调查。认真的参与者比不认真的参与者更一致和更具预测性地回答了一些态度和行为问题。因此，我们建议在在线调查中定期进行认真程度检查，以提高数据的有效性。
