Surviving the screens: the problem of hidden inattentive respondents in online surveys
2026-01-07
Inattentive survey respondents are a growing concern for social scientists who rely on online surveys for their research. While inattentiveness has been well documented in lower quality sample sources, there is less understanding of how common the phenomenon is in high-quality surveys. We document the presence of a small percentage of respondents in Cooperative Election Study surveys who pass quality control measures but still exhibit inattentive behavior. We show that these respondents may affect public opinion estimates for small subgroups. Finally, we present the results from an experiment testing whether inattentive respondents can be encouraged to pay more attention, but we find that such an intervention fails.
