“…Compared to laboratory or survey experiments, they can be conducted with high external validity because they do not suffer from low response rates or self-selection bias as non-responses also count as an observation, and artificiality is less of a problem as they take place in a natural context. As such, field experiments provide important insights into the input legitimacy of democracy, such as racial discrimination (Broockman, 2013; Dinesen et al, 2021; Gell-Redman et al, 2018), gender bias (Magni and de Leon, 2020; Thomsen and Sanders, 2020; Wiener, 2020), the electoral prerequisites of geographic representation (Bol et al, 2021; Breunig et al, 2021; Giger et al, 2020), and responsiveness to public-policy preferences (Butler and Nickerson, 2011; Butler et al, 2012). In this vein, field experiments help us to critically assess the quality of democracy and identify needs for reform as well as unsubstantiated fears.…”
