Team Reasoning from an Evolutionary Perspective: Categorization and Fitness

& drangbrac;Team Reasoning aus evolutionarer Perspektive: Kategorisierung und Fitness & DLANGBRAC;. The question of the evolutionary stability of team reasoning has been answered in multiple, even opposing ways. We provide a general, con-ceptual categorization of these existing answers along four dimensions: (1) the unit of selection, (2) the notion of fitness for team reasoners, (3) the stage of decision-making, and (4) the ludic ecology. Beyond affording a better as-sessment of the different modeling choices underlying the existing results, the categorization highlights important conceptual questions for the evolu-tionary foundations of team reasoning. We illustrate this by looking in more detail into what should count as fitness for team reasoners.
