Violations of Bayesian updating within Expected Utility

We study violations of Bayesian updating within a standard setting of preferences that satisfy the Subjective Expected Utility axioms. We show that Bayesian updating will be corroborated if and only if utility function is signal-independent. In this sense, we characterize when violations of Bayesianism can be attributed to belief elicitation errors due to failure to take into account that people may care about the information they receive or the associated beliefs in an intrinsic way, like in the extensive literature on belief-dependent motives and emotionally-dependent beliefs.
