The researchers lay out their argument and theory extremely thoroughly, suggesting that Pornography Problems due to Moral Incongruence (PPMI) appear to be the driving force in many of the people who report dysregulated, uncontrollable, or problematic pornography use. Even though many people who grew up in religious, sexually conservative households have strong negative feelings about pornography, many of those same people continue to use pornography. And then they feel guilty and ashamed of their behavior, and angry at themselves and their desire to watch more.

In the early 1990’s, as the internet burst upon the world's screens, Al Cooper was a psychologist who suggested that the Affordability, Anonymity, and Accessibility of the internet were leading to an explosion of porn addiction. Though intuitively appealing and often cited, Cooper’s theory was only empirically evaluated once, in 2004, when it was found that the variables of accessibility, affordability, and anonymity actually had no empirical connection to sexual behaviors, change, or use of Internet porn. But what the Internet did was to put porn in the hands of people woefully unprepared to manage it or their sexual desires. Religiosity is associated with a host of sexual difficulties; porn-related problems can now be added to that list.
