Some researchers in philosophy of religion have charged that the sub-discipline exhibits a number of features of poor health, prominently including that “partisanship is so entrenched that most philosophers of religion, instead of being alarmed by it, just take it for granted”. But while these studies indicate that there is a correlation between religious belief and judgments about natural theological arguments, they do not establish that causation runs from belief to judgment as has been claimed. In this paper I offer an alternative explanation, suggesting that thinking style is a plausible common cause.
