Although optimal models are useful, optimality claims are not that common.

Rahnev & Denison (R&D) argue that human behavior is often described as "optimal," despite many previous findings of suboptimality. We address how the literature handles these concepts and discuss our own findings on suboptimality. Although we agree that the field should embrace the "systematic weirdness of human behavior" (sect. 6, para. 1), this does not detract from the value of the Bayesian approach.
