不认真的回答行为增加了噪声，降低了实验功率；因此，这是对在线研究有效性最重要的威胁之一。解决这个问题的一个简单方法是询问受访者他们参与的严肃性，并将自称不认真的参与者排除在分析之外。为了验证这种方法，在2009年德国联邦议院选举前一周进行了一项调查。严肃的参与者比不严肃的参与者以更一致和更有效的方式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使用严肃性检查来提高数据的有效性。
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.
