This section of the site provides critiques studies about which YBOP and others have reservations. In some, the methodology raises concerns. In others, the conclusions appear inadequately supported. In others, the title or terminology used is misleading given the actual study results. Some grossly misrepresent the real findings. For most papers, clicking on a study title takes you directly to an analysis of it. In the analysis you will find links to the original papers. In addition to critiques of studies, a few selected propaganda pieces are debunked. (If you are looking for studies relevant to Internet porn use visit this page.)
In response to proliferation of biased articles in the press YBOP wrote this: How to recognize biased articles: They cite Prause et al. 2015 (falsely claiming it debunks porn addiction), while omitting over 3 dozen neurological studies supporting porn addiction (April, 2016). For a debunking of nearly every talking point and cherry-picked study see this extensive critique: Debunking “Why Are We Still So Worried About Watching Porn?”, by Marty Klein, Taylor Kohut, and Nicole Prause (2018). If you want a simple video addressing many of the myths propagated by researchers or bloggers see: (Video) PORN MYTHS – The Truth Behind Addiction And Sexual Dysfunctions, by Gabe Deem. The following talks (on vimeo) were presented at the 2018 NCOSE conference:
- “People Recognize Porn-Science Propaganda When They See It” by Jacob Hess – An overview of tactics employed by “astroturfers” who deny the possible negative effects of porn use.
- Gary Wilson – “Porn Research: Fact or Fiction?” – Wilson exposes the truth behind 5 studies propagandists cite (all listed below) to support their claims that porn addiction doesn’t exist or that porn use is largely beneficial.
