Thinking through prior bodies: autonomic uncertainty and interoceptive self-inference

The Bayesian Brain Hypothesis, as formalized by the Free Energy Principal, is ascendant in the cognitive sciences. But how does the Bayesian Brain obtain prior beliefs? Veissière and colleagues argue that sociocultural interaction is one important source. We offer a complementary model in which “interoceptive self-inference” guides the estimation of expected uncertainty both in ourselves and in our social conspecifics.
