We replicate only the eight conjoint studies listed in Table A1; the conjoint method has been used by many others in our discipline and beyond. Systematic reviews of conjoint applications in political science include De la Cuesta, Egami, and Imai (2022), which finds that 59 conjoint experiments were published in ten of the discipline’s top journals from 2014 to 2019, and Ganter (2021), indicating that 61 conjoint experiments appeared in six of the discipline’s top journals from 2014 to 2021. Likewise, Schwarz and Coppock (2022) analyze 67 candidate-related conjoint experiments that include a gender attribute, Eshima and Smith (2022) analyze 16 candidate conjoint experiments that include an age attribute, and Incerti (2020) finds 26 studies that study candidate corruption and vote choice.

Outside of political science, conjoint experiments are no less popular. In environmental science, Alriksson and Öberg (2008) record 84 studies evaluating preferences for environmental policy and Mamine, Minviel, et al.(2020) list 70 studies related to agrienvironmental practices; in marketing, Bastounis et al.(2021) analyze 43 conjoint experiments manipulating sustainability labeling on food products.
