Team Reasoning from an Evolutionary Perspective: Categorization and Fitness

Abstract

The question of the evolutionary stability of team reasoning has been answered in multiple, even opposing ways. We provide a general, conceptual 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 assessment of the different modeling choices underlying the existing results, the categorization highlights important conceptual questions for the evolutionary foundations of team reasoning. We illustrate this by looking in more detail into what should count as fitness for team reasoners.
