Is religiosity related to porn use? It turns out, yes.
Religiosity and social conservatism are typically associated with more traditional values, especially when it comes to sex. Rules about who, when, where, and how can be quite rigid. There's a long history of law being influenced by these rules (e.g., laws against homosexuality).
But, this fixation on rules and being "good" can backfire. The more one thinks about the things that they're not supposed to be doing, the more one tends to think about those things (if you've never heard of the white bear experiment, Google it). Fixation becomes preoccupation. And sex is already something people think about a lot.
In the linked study, the researchers looked at the relationships between proportion of people who identified as "very religious" and people who defined themselves as conservative, and frequency of Google searches for porn. They did this on a state-by-state basis.
What they found was that more religious and conservative states searched much more frequently for porn than states that are less religious and conservative.
Not at all coincidentally, a previous study showed that the most religious and conservative states have the highest subscription rates to porn sites.
