“…Although survey results could reflect "expressive responding," meaning that reported behaviors varied by partisan identity even though actual behaviors did not, substantial evidence suggests that the two communities were behaving as reported. Gollwitzer et al (2020) measured aggregate movement data from cell phones as a function of county vote share in the 2016 election and found the extent to which people traveled outside of the home during the early months of COVID, when stay-at-home mandates were in effect, varied by county-level partisanship even when controlling for numerous factors that could explain away the relationship (for similar results, see Allcott et al, 2020;Barbalat & Franck, 2022;Barrios & Hochberg, 2021;Camobreco & He, 2022;Grossman et al, 2020;Im et al, 2021;Kavanagh et al, 2021). Once vaccines became available, uptake also followed partisan patterns (Leonhardt, 2021), and mortality eventually reflected these differences (Bernet, 2022;Neelon et al, 2021;Sehgal et al, 2022;Wallace et al, 2022).…”
