McKay & Dennett (M&D) observe that beliefs need not be true in order to evolve. We connect this insight with Schelling's work on cooperative commitment to suggest that some beliefs – ideologies – are best approached as social goals. We explain why a social-interactive perspective is important to explaining the dynamics of belief formation and revision among situated partners.
