“…While survey experiments have traditionally examined just one or two factors that might shape outcomes (see, for reviews, Gaines, Kuklinski, and Quirk, 2007;Sniderman, 2011), conjoint designs allow researchers to study the independent effects on preferences of many features of complex, multidimensional objects. These include many different types of phenomena, such as political candidates (Campbell et al, 2016;Teele, Kalla, and Rosenbluth, 2018), immigrant admissions (Hainmueller and Hopkins, 2015;Bansak, Hainmueller, and Hangartner, 2016;Wright, Levy, and Citrin, 2016), and public policies (Gallego and Marx, 2017;Hankinson, 2018). Factorial designs of this sort have a long history, but the driving force behind this use of conjoint analysis has been the introduction by Hainmueller, Hopkins, and Yamamoto (2014) of a small-sample, fully randomized conjoint design.…”
