I participate as a researcher and have also participated as a participant. From a researcher’s perspective, I can see the value in attention checks, (and indeed I have excluded participants in the past because they have failed attention checks). However, I have found other means (especially by looking for outliers), to spot those who are not fully engaged with the study. From the perspective of a participant I find them insulting to the intelligence. In fact I always give feedback as such to the researchers. From a psychological point of view, it’s important for the participant to be in a receptive and cooperative mood, so that they have the motivation to put maximum effort into the study. After all, they are giving up their time to help the researcher with their research. However, whenever I have been confronted by attention checks, especially where they are spattered liberally across a study, then it puts me into a negative mood. I get cross that my honesty integrity is being doubted. As a researcher, there are statistical ways to spot someone who is not paying attention (looking for patterns, outliers etc), so I for one, won’t be using attention checks any more. I would rather make my survey so interesting that participants found it a rewarding experience.
