The experimental design is a information provision protocol. We ran an online survey with representative sample of adult Finns at the age between 35 and 45 years old. The study was pre-registered before the data collection. In the survey, the participants were asked to assess their income ranks in each of five reference groups (Educational, Occupational, Municipal, Age cohort, National), then they were informed of their income rank in one reference group. The participants in Control group saw no information. In addition, we have treatment Choice where the participants were allowed to choose in which group that they would most like to see their income rank and they saw their rank in the chosen group. The rest of the survey for treatment Choice was the same as the other treatment groups with information. After the information, they asked questions regarding their individual well-being, just world beliefs, attitudes toward policies (redistribution, welfare, labor market, migration, etc.), attitudes toward societal issues, and real-stake tasks (how much of their earning to donate to charity and voluntary tax, and how much to purchase a lotto). In the end, they saw a summary of the survey including their payment (15 euro conditional completing the survey, 5 euro if correct assessment of income rank of a randomly chosen group).
