This section of the site provides critiques of studies and commentaries about which YBOP and others have serious reservations. In some, the methodology raises concerns. In others, the conclusions appear inadequately supported. And, in others, the title or terminology used is misleading given the actual study results. Some grossly misrepresent the real findings. Others cherry-pick studies and misrepresent the studies they do cite. Clicking on the name of study takes you directly to an analysis of it. In the analysis you will find links to the original paper. In addition to critiques of studies, selected propaganda pieces are debunked. (If you are looking for studies relevant to 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 50 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.
Update (April, 2019)
In an attempt to silence YBOP’s criticism, a handful of authors formed a group to steal YBOP’s trademark. See this page for details: Aggressive Trademark Infringement Waged by Porn Addiction Deniers (www.realyourbrainonporn.com).
If you are looking for an analysis of a study that you cannot find on this “Critiques of Questionable & Misleading Studies” page, check this page: Porn Science Deniers Alliance (AKA: “RealYourBrainOnPorn.com” and “PornographyResearch.com”). It examines the trademark infringers’ “research page,” including its cherry-picked outlier studies, bias, egregious omissions, misrepresentation of the studies it does list, and outright deception.
