Can online experiences that illustrate the lives of vulnerable populations improve prosocial behaviors and reduce prejudice? We randomly assign 850 individuals to: i) an online game that immerses individuals in the life decisions of a Venezuelan migrant and ii) a documentary about the migration process of Venezuelans to Colombia. Both treatments effectively improve altruism and reduce prejudice towards migrants. The impacts of both treatments are not statistically different in any of the other outcomes that we examine. The effects of the game are mainly driven by changes in perspective-taking while the effects of the video are induced by changes in both empathy and perspective-taking.
