Theories of rationality typically focus on the internal coherence of beliefs, values and actions, but perhaps such coherence is of marginal significance for cognitive function—perhaps, for example, we should focus instead on correspondence with reality, rather than coherence between beliefs, or the ability of a person to deploy decision-making strategies that are effective in their ecological environment, rather than justified in terms of underlying beliefs and desires (e.g., [ 17 , 18 ]).
