This project is a joint effort between different member of the social psychology lab at the university of Zurich. Three separate questionnaires have been prepared in 2020, 2021, 2022 as part of this project. Note that most modules/set of questions as well as participation differ based on the year of data collection. This documentation is for the year 2020. In 2020, we recruited a quota-sample of approximately 1'000 participants from the panel provider Bilendi. The sample is quasi-representative for the German speaking parts of Switzerland in their distributions of age, gender, and state of residence. Each lab member proposed a module of questions with –in some cases– an experimental design. The modules of questions include the following topics: 1. Political party preferences. 2. Job-related competencies and decision-making conflicts. 3. Personal lifestyle and physical activity. 4. Gender inequalities (i.e., focusing on price differences for hairdressers depending on gender). 5. Contact with refugees. 6. Norms and Covid-19-related hygiene measures. 7. Shopping preferences (e.g., decisions to buy shampoo and body lotions). 8. Gender-based attitudes toward men and women in the medical field. 9. Opinions and perceived norms toward various social issues in Switzerland (e.g., racial minorities, marriage for all, third gender option). It also includes key demographic variables (e.g., nationality, age, gender, sexual orientation, canton of residence). Several sections contain an experimental design (see codebook). The material is available in German and (partially) in English. Robert Tobias and Simone Sebben deserve credit for doing the major share of work involved in programming of the survey, troubleshooting, and monitoring of the quotas. Léïla Eisner prepared the data for publication.
