The purpose of this article should become plain during the reading of it, but perhaps some prior explanation is needed. Almost from the beginning of my study of the paṭiccasamuppāda I have had the notion that it could not have come into existence in the form the usual twelvefold formulation takes. For reasons which I try to make clear this twelvefold formulation is not a satisfactory statement of what it is supposed to explain, namely the reasons for each individual's continued rebirths. I feel - and sadly I have to emphasize, before someone else does it for me, that in the final analysis I am relying more or less on intuition for my attitude towards the twelvefold formulation - that if one person alone had been responsible for the usually referred to formulation, and especially if that one person had been the Buddha, then those anomalies that now prevail would never have existed

I clarify and defend the hypothesis that human belief formation is sensitive to social rewards and punishments, such that beliefs are sometimes formed based on unconscious expectations of their likely effects on other agents – agents who frequently reward us when we hold ungrounded beliefs and punish us when we hold reasonable ones. After clarifying this phenomenon and distinguishing it from other sources of bias in the psychological literature, I argue that the hypothesis is plausible on theoretical grounds and I show how it illuminates and unifies a range of psychological phenomena, including confabulation and rationalisation, positive illusions, and identity-protective cognition.

A large and growing body of research in computational psychiatry draws on Bayesian modelling to illuminate the dysfunctions and aberrations that underlie psychiatric disorders. After identifying the chief attractions of this research programme, we argue that its typical focus on abstract, domain-general inferential processes is likely to obscure many of the distinctive ways in which the human mind can break down and malfunction. We illustrate this by appeal to psychosis and the social phenomenology of delusions.
