Partisanship Unmasked? The Role of Politics and Social Norms in COVID-19 Mask-Wearing Behavior – CORRIGENDUM

In Carey et al. (2023), we presented an experiment embedded within a panel survey assessing whether alerting Americans to either national, co-partisan, or opposing partisan descriptive norms of mask-wearing affected their own mask-wearing intentions.This descriptive norm was presented as the percentage of Americans, Democrats, or Republicans who claimed to wear masks at least 'most of the time.'We found that alerting participants to the national norm, but not the co-partisan or opposing partisan norms, increased mask-wearing intentions.This was particularly the case for Republicans and those who previously underestimated Americans' levels of mask-wearing.Before proceeding in greater detail, we want to extend our extreme gratitude to Katharina Isser for uncovering some issues and bringing them to our attention.We regret the errors in the original.Descriptive statistics on the percentage of respondents that under-and overestimate Americans,' Democrats', and Republicans' mask-wearing presented in Table 1 were incorrect.Part of this was due to coding error.The thresholds used for under-/over-estimation for Americans matched the full sample (70% and 90%, respectively), rather than the general population sample as pre-registered (64% and 84%, respectively).The threshold for under-/over-estimating Democrats' maskwearing needed to be slightly adjusted from 80%/98% to 79%/99%.Finally, instead of over-estimation being coded as 66% for Republicans, it was erroneously coded at 56%.However, even with the original code produced, discrepancies existed, for which the source is unknown.In the interest of full transparency, Table 1 presents the rates of under-/over-estimation reported in the original paper, by the replication code, and by the corrected code.The substantive interpretation of relative differences between the full sample, Democrats, and Republicans generally doesn't change (though Republicans no longer underestimate national mask-wearing more than others), but absolute percentages do change.
