Theories in the cognitive science of religion (CSR) are sometimes seen as debunking religious or supernatural beliefs (SBs). To date, arguments have been produced by proponents on both sides, with some claiming that debunking would result and others claiming that it would not. In this paper, I depart from the approach taken by others and offer an approach based in broadly Bayesian methods of updating subjective probability assignments, including classical Bayesian formulas as well as comparative ratios and Jeffrey conditionalization. I (...) argue that debunking may take place, but only if specified conditions are met. One way to show that debunking takes place would be to show that the probability of some CSR theory naturalistically explaining SBs diminishes when it is postulated that SBs have epistemic warrant. Another alternative would be to show that CSR theories are less likely to succeed in explaining the origin of SBs if SBs have warrant than if they lack warrant. It can also be helpful to consider the role played by uncertain and even ineffable judgments. Either way, debunking SBs does not follow simply from CSR but must be considered in light of prior epistemic commitments and the role they play in evaluating probabilities. (shrink)

A central claim often made to debunk religious beliefs is that they would be formed regardless of whether they are true or false. One way to support this claim is to apply findings from the cognitive science of religion. However, this use of science in an argument against religious beliefs has been strongly criticized. This article is about weaknesses in that criticism. I consider two arguments. Firstly, the critic of debunking can argue that the debunker makes empirically dubious claims about (...) the origin of religious beliefs. I argue that the debunker can avoid this problem because the controversial empirical claims are not necessary. General naturalistic assumptions about the origin of religion also create worries that support the central debunking claim. The second criticism focuses on the highly general nature of the claims or assumptions debunkers make about the origin of religious beliefs. Critics maintain that such claims or assumptions, even if true, fail to affect the specific religious beliefs you or I form. I respond, arguing that this criticism fails to engage with the most prominent version of debunking, which aims at classes of beliefs. Furthermore, by making a detour through a related discussion in metaethics, I show how this version of the debunking argument can be extended in such a fashion that it applies to a given individual who forms a religious belief.
