Threat‐Inducing Violent Events Exacerbate Social Desirability Bias in Survey Responses

A key challenge in survey research is social desirability bias: respondents feel pressured to report acceptable attitudes and behaviors. Building on established findings, we argue that threat‐inducing violent events are a heretofore unaccounted for driver of social desirability bias. We probe this argument by investigating whether fatal terror attacks lead respondents to overreport past electoral participation, a well‐known and measurable result of social desirability bias. Using a cross‐national analysis and natural and survey experiments, we show that fatal terror attacks generate turnout overreporting. This highlights that threat‐inducing violent events induce social desirability, that researchers need to account for the timing of survey fieldwork vis‐à‐vis such events, and that some of the previously reported post‐violent conflict increases in political participation may be more apparent than real.
