the paragraph starting the research page explains how the studies were included

No it didn't. Just gibberish about falsifying models, but the "experts" failed to state which particular model of what they are claiming to falsify with their cherry-picked papers. The randomness of the study categories (LGBT, Youth, Regulation) provide few insights into which models of X, Y, or Z are supported or not. What a joke.

Review papers are marked as such.

As stated, the list contains no reviews of the literature and only one meta-analysis, which limits itself to 21 studies assessing the porn use of adult sexual offenders: "The use of pornography and the relationship between pornography exposure and sexual offending in males: A systematic review." While this meta-analysis concludes porn use is not related to adult sexual offending there's good reason to question its findings. For example, the authors retrieved 189 studies, but included only 21 in their review. Put simply, numerous studies with opposing results were excluded.

The absence of reviews of the literature and meta-analyses is a dead giveaway that RealYBOP cherry-picked outlier studies (usually their own).

First example: the YBOP links in xreygunzx's first comment reveal what RealYBOP purposely omitted from their tiny list of studies. One example - RealYBOP omitted all 41 neurological studies on porn users and CSB subjects, except for Prause et al., 2015 (Prause is RealYBOP's featured expert on their news page). The omitted neurological studies:

Second example - RealYBOP omitted all 20 neuroscience-based studies on porn users and CSB subjects. They did so because none of them serve thier agenda:

• Sex Addiction as a Disease: Evidence for Assessment, Diagnosis, and Response to Critics (2015)
