Methodology
Research design and Participants
To test the hypotheses, we conducted an experiment with a 2×2 between-subjects factorial design. The experiment was conducted in a computer laboratory and was programmed in z-Tree (Fischbacher [2007]). Following the experimental economics tradition, we refrained from using any kind of participant deception. The experimental task consisted of selecting the correct answer or solution(out of four alternatives) for a maximum of a hundred general knowledge questions and calculations.
