Survey researchers are making increasing use of paradata - such as keystrokes, clicks, and timestamps - to evaluate and improve survey instruments but also to understand respondents and how they answer surveys. Since the introduction of paradata, researchers have been asking whether and how respondents should be informed about the capture and use of their paradata while completing a survey. In a series of three vignette-based experiments, we examine alternative ways of informing respondents about capture of paradata and seeking consent for their use. In all three experiments, any mention of paradata lowers stated willingness to participate in the hypothetical surveys. Even the condition where respondents were asked to consent to the use of paradata at the end of an actual survey resulted in a significant proportion declining. Our research shows that requiring such explicit consent may reduce survey participation without adequately informing survey respondents about what paradata are and why they are being used.
调查研究人员越来越多地利用副数据（如击键、点击和时间戳）来评估和改进调查工具，同时也用于了解受访者以及他们回答调查的方式。自从引入副数据以来，研究人员一直在询问，在完成调查时，是否以及如何告知受访者其副数据的收集和使用情况。在一系列三个基于 vignette 的实验中，我们研究了告知受访者副数据收集情况并寻求其使用同意的替代方法。在所有三个实验中，任何关于副数据的提及都会降低表示愿意参与假设调查的意愿。即使在实际调查结束时要求受访者同意使用副数据的情况下，也有很大比例的人拒绝。我们的研究表明，要求这种明确同意可能会降低调查参与度，而没有充分告知受访者什么是副数据以及为什么要使用它们。
