Polarization and Cooperation: A Behavioral Experiment (with Ignacio Jurado and Albert Falcó)
This paper explores the effects of affective polarization on cooperative behavior through a behavioral experiment conducted in Brazil and Spain. Participants were asked to perform a simple, one-shot asynchronous task: converting to capital letters either a neutral salad recipe or a politically charged text written by another individual. The experiment varied also both the political affiliation of the original author—presented as a supporter of the participant’s most liked or disliked political party—and the type of reward offered for task completion.
