One caution about religiosity

It is worth saying what the research does and does not find here, because it is easy to misread.

Being religious does not cause this. What studies find is that where scrupulosity does turn up alongside strong religiosity, the road between the two runs through two specific things. A belief that you must control what appears in your mind, and guilt at having failed to.

That is a belief about thoughts. It is not a teaching of the religion. The religion, as you saw two lessons ago, says close to the opposite.
