Team reasoning theory: an experimental analysis of common reason to believe and social distance

The aim of this paper is to study the role of the “common reason to believe” (Sugden in Philos Explor 16:165–181, <CitationRef CitationID="CR51">2003</CitationRef>) and the reduction of social distance within the theory of team reasoning. The analysis draws on data collected through a Traveler’s Dilemma experiment. To study the role of the common reason to believe, players’ beliefs in their counterparts’ choices are elicited, and the correlation between the endorsement of team reasoning and beliefs is considered. The relation between social distance and team reasoning is analyzed by introducing a meeting between the two players after the game. We show that the common reason to believe appropriately explains the internal logic of team reasoning and that a reduction of social distance does not produce any statistically significant effect on the probability that team reasoning will be used.
