Abstract

The foundational theme of the target article is that processes of self-deception occur in a functional context: a social one through which self-deceptive processes enhance fitness by affecting an actor's performances. One essential component of this context not addressed explicitly is that audiences should have been selected to resist, where possible, enhancements falsely bolstered by self-deception. Theoretical implications follow.
