Primary Outcomes (End Points) We want to measure all dimensions of prosociality through economic games. We will use the following canonical games: - Dictator game - Ultimatum game - Trust game - Third party game Instruction for participants on each of these games is provided at the Materials sections. We want to measure all dimensions of prosociality through economic games. We will use the following canonical games: - Dictator game - Ultimatum game - Trust game - Third party game Instruction for participants on each of these games is provided at the Materials sections. We will also measure psychological traits with canonical tests in the psychology literature. These include: - Inclusion of the Other in the Self scale. - Reading the Mind in the Eyes test. - We have also created an questionaire that tries to measure a possible mechanism for our result: the value given to the aesthetic experience of the other. We have called this questionaire the GUERRA measure.
Primary Outcomes (Explanation) We understand prosociality as the share of the personal income that an individual is willing to share with others. This share is different depending on each situation, and that is why we use different economic games. In any cae, this is a more objective measure than the ones we find in the existing literature.

Will we think there are many things to improve on the existing literature, we still want to be able to have a dialogue with existing papers. This also allows us to valdiate our findings with economic games as the result of real changes in preferences.
Planned Number of Clusters For the pilot we have 60 enrolled students (30 in each course). For the pilot we have 60 enrolled students (30 in each course). For the experiment itself we will have around 200 students, 100 on each treatment arm.

Sample size (or number of clusters) by treatment arms 30 students in control and treatment arm for the first instance of the pilot. We aim at having at least two additional rounds in 2025-II and 2026-I with at least 50 students in each experimental condition. That is, we will have at least 130 in control and 130 in treatment in the pilot 30 students in control and treatment arm for the first instance of the pilot. 100 in each arm during implmentation at Universidad de los Andes.
