Abstract

Sensitive behaviors such as self-reported performance or (un)ethical behaviors often carry strong social connotations of appropriate or inappropriate conduct. In return, social norms can artificially inflate or deflate individuals’ responses and bias scientific results on their prevalence and effects. As a core part of governments’ mitigation strategy against the outbreak of COVID-19, social distancing might represent one of these behaviors. Can researchers expect honest responses when surveying citizens about their social distancing behaviors? This question is examined using the sensitive survey technique, “the crosswise model”, to elicit aggregate-level prevalence estimates of (1) self-reported social distancing, and (2) honest reporting in a prediction dice game. Since the number of wins in the dice game follows a known probability distribution, it offers an excellent setting for illustrating the utility of the crosswise model before applying it to self-reported social distancing. In a survey of 1,059 adults living in the US, the crosswise model outperforms direct questioning in revealing respondents’ dishonest behavior in the dice game. While the crosswise model also indicates some social desirability bias when asking respondents directly about their social distancing behaviors, the extent of this bias seems small and does not appear to overtly inflate individuals’ self-reported measures of social distancing.

Highlights

Sensitive behaviors such as self-reported performance orethical behaviors often carry strong social connotations of appropriate or inappropriate conduct
Since social distancing is touted as the appropriate behavior and the responsible way to act to help slow the spread of COVID-19, the social values placed on such behaviors might dictate individuals’ responses to the research team’s survey rather than reflect people’s true preferences or actions
We might be concerned that citizens depict their behaviors in ways that reconcile with social norms to promote social distancing; especially when asked explicitly to reveal their status on the sensitive behaviors making up social distancing, such as staying at home and refraining from social interaction in close physical spaces

Summary

Introduction

Sensitive behaviors such as self-reported performance or (un)ethical behaviors often carry strong social connotations of appropriate or inappropriate conduct. If social desirability bias is a concern, we would expect the crosswise model to produce lower estimates for social distancing behaviors compared to direct questioning.
