have conducted a meta-analysis of research on pornography and concluded that porn use does not predict problems with porn, but that religiosity does.

I think there's some important nuance here that isn't conveyed in the headline. Like I once knew someone who would compulsively browse porn even in inappropriate/risky situations like while they were at work; they did clearly have some kind of problem. But the nature of the problem seemed to be more along the lines of a sometimes-unhealthy coping mechanism for their preexisting mental health struggles than a situation where they started looking at porn and that decision was the cause of the problem, and would have caused the same problem for someone else.
