The challenge of explaining how cognition can be tractably realized is widely recognized. Classical rationality is thought to be intractable due to its assumptions of optimization and/or domain generality, and proposed solutions therefore drop one or both of these assumptions. We consider three such proposals: Resource‐Rationality, the Adaptive Toolbox theory, and Massive Modularity. All three seek to ensure the tractability of cognition by shifting part of the explanation from the cognitive to the evolutionary level: Evolution is responsible for producing the tractable architecture. We consider the three proposals and show that, in each case, the intractability challenge is not thereby resolved, but only relocated from the cognitive level to the evolutionary level. We explain how non‐classical accounts do not currently have the upper hand on the new playing field.

难处理性如何跨越解释的认知和进化层面。

解释认知如何易于实现的挑战已得到广泛认可。由于其优化和/或领域通用性的假设，经典理性被认为是棘手的，因此提出的解决方案放弃了这些假设中的一个或两个。我们考虑三个这样的建议：资源理性、自适应工具箱理论和大规模模块化。这三者都试图通过将部分解释从认知层面转移到进化层面来确保认知的易处理性：进化负责产生易处理的架构。我们考虑了这三个提议，并表明，在每种情况下，棘手的挑战都没有因此得到解决，而只是从认知层面转移到进化层面。我们解释了非经典账户目前如何在新的竞争环境中不占上风。
