SYSTEMATIC-ERRORS AND THE THEORY OF NATURAL-SELECTION

This paper derives two main results. First, in a world where inheritance is sexual as opposed to asexual ''second-best'' adaptations can be evolutionarily stable. That is, the adaptation selected need not be the optimal solution to the evolutionary problem at hand. Second, I apply this result to show that natural selection provides a potential explanation for why in many settings humans commit errors that are systematic in nature.
