This paper argues that one can empirically test, via positivist methods, the post-modern attack on positivist epistemologies: Postmodern perspectives hold Knowledge and Truth to be intersubjective, consensus-driven social constructions. But traditional scientific approaches to knowledge, exemplified here by the cognitive social psychology of persuasion, seem oblivious to this and continue to detach the study of attitudes, beliefs, and emotions from that of knowledge, facts, and reason. Abandoning these artificial distinctions in both epistemology and method would enable this social psychology, reconstituted (...) as a Sociology of Persuasion, to contribute greatly to illuminating the processes of Truth and Knowledge construction in social interaction. Moreover, this would facilitate academic engagement in civic discourse. (shrink)

Von Hippel & Trivers (VH&T) interpret belief in God and belief in strong government as the outcome of an active process of self-deception on a worldwide scale. We propose, instead, that these beliefs might simply be a passive spin-off of efficient cognitive processes.

It is timely to assess Bayesian models, but Bayesianism is not a religion. Bayesian modeling is typically used as a tool to explain human data. Bayesian models are sometimes equivalent to other models, but have the advantage of explicitly integrating prior hypotheses with new observations. Any lack of representational or neural assumptions may be an advantage rather than a disadvantage.

Humans are not the only animals to deceive, though we might be the only ones that lie. The arms race von Hippel & Trivers (VH&T) propose may have only started during hominin evolution. VH&T offer a powerful theory, and I suggest it can be expanded to explain why there are systematic biases in human foresight.
