Abstract

This commentary describes another variety of self-deception, highly relevant to von Hippel & Trivers's (VH&T's) project. Drawing on dual-process theories, I propose that conscious thinking is a voluntary activity motivated by metacognitive attitudes, and that our choice of reasoning strategies and premises may be biased by unconscious desires to self-deceive. Such biased reasoning could facilitate interpersonal deception, in line with VH&T's view
