John A. Johnson on Steele et al., 2013 (and Johnson debating Nicole Prause in comments section under his Psychology Today article)

Steele et al., 2013 spokesperson Nicole Prause conducted several interviews about her July, 2013 EEG study on people complaining of having difficulties controlling their porn use. Commenting under the Psychology Today interview of Nicole Prause, senior psychology professor emeritus John A. Johnson said: A gap in logical inference Submitted by John A. Johnson Ph.D. on […]

Analysis of “Data do not support sex as addictive” (Prause et al., 2017)

Introduction Nicole Prause touts yet another of her letters to the editor as “debunking” the existence of sex addiction and porn addiction (“Compulsive sexual behaviour disorder” in the upcoming ICD-11). Yet it does not. This 240-word opinion piece (Prause et al., 2017) cites zero studies to support its claims, providing only a single, easily refuted […]

Peer-reviewed critiques of Steele et al., 2013

Background: Steele et al., 2013 On March 6th, 2013 David Ley and spokesperson Nicole Prause teamed up to write a Psychology Today blog post about Steele et al., 2013 called “Your Brain on Porn – It’s NOT Addictive“. Its oh-so-catchy title is misleading as it has nothing to do with Your Brain on Porn or […]

Dismantling David Ley’s Response to Philip Zimbardo: “We Must Rely on Good Science in Porn Debate” (2016)

The following is YBOP’s response to David Ley’s Psychology Today blog post “We Must Rely on Good Science in Porn Debate (2016).” Ley’s post is his response to Philip Zimbardo’s Psychology Today blog post “Is Porn Good For Us or Bad For Us?” (2016). While Ley’s title says we must rely on “good science,” it […]

Nicole Prause’s efforts to have Behavioral Sciences review paper (Park et al., 2016) retracted

CONTENTS: “Who’s watching Retraction Watch?” – an update on events. Background – general Pre-MDPI history: the Yale Journal of Biology & Medicine, and “Janey Wilson”. Behavioral Sciences version of Park et al., and Prause’s retraction efforts Prause uses social media to harass MDPI and researchers who publish in MDPI journals May, 2018 – Prause creates […]

Analysis of “Does exposure to erotica reduce attraction and love for romantic partners in men? Independent replications of Kenrick, Gutierres, and Goldberg (1989) study 2”

COMMENTS: This new study (abstract below) is being touted as a “failed replication” of a highly cited 1989 experiment, thus proving that porn use has little effect of intimate relationships. First, it’s absurd to claim that experimental studies can demonstrate if porn viewing really causes negative relationship effects.” Experiments where college-aged guys view a few […]

Critique of “The 2018 Revision to the Process of Care Model for Evaluation of Erectile Dysfunction” (2018)

  COMMENTS: At first glance this 2018 paper seemed promising as it recommended that pornography use be added as a part of patient evaluation: As part of the sexual history, information on sexual habits can be useful, both in diagnosing ED and in selecting the optimal treatment. Sexual habits include frequency of intercourse, predictability, timing, […]

Critique of “Profiles of Cyberpornography Use and Sexual Well-Being in Adult” (2017)

COMMENTS: The present study is a further analysis of an earlier study that has already been critiqued by YBOP: Cyberpornography: Time Use, Perceived Addiction, Sexual Functioning, and Sexual Satisfaction (2016). Both studies involved the same subjects, with the earlier study reporting that greater porn use was related to both less sexual satisfaction and less sexual […]

Critique of “Cyberpornography: Time Use, Perceived Addiction, Sexual Functioning, and Sexual Satisfaction” (2016)

COMMENTS: This study reported two seemingly contradictory findings in regard to porn use: More time spent viewing porn correlated with lower sexual satisfaction More time spent viewing porn correlated with less sexual dysfunction Wouldn’t it make sense for poorer sexual satisfaction to always be related to more sexual dysfunction? How could more porn use be […]

Debunking Justin Lehmiller’s “Is Erectile Dysfunction Really on the Rise in Young Men” (2018)

Justin Lehmiller, a regular paid contributor to Playboy Magazine, unconvincingly attempts to debunk the well documented rise in youthful erectile dysfunction with this April, 2018 blog post. Since it was published David Ley and Nicole Prause frequently tweet Lehmiller’s blog post as “proof” that youthful ED rates haven’t changed in the last 30 years. According […]

Research Suggests the Grubbs, Perry, Wilt, Reid Review Is Disingenuous (“Pornography Problems Due to Moral Incongruence: An Integrative Model with a Systematic Review and Meta-Analysis”)

The authors of this review would have readers believe that self-identification as a porn addict is a function of religious shame/moral disapproval about porn. They only reviewed a small number of studies, which rely on the CPUI-9, an instrument developed by co-author Grubbs that produces skewed findings. The co-authors carefully omitted or misrepresented opposing research […]

Debunking “Why Are We Still So Worried About Wat­­ching Porn?” (by Marty Klein, Taylor Kohut, and Nicole Prause)

Introduction This critique has two parts: Part 1 exposes how Nicole Prause, Marty Klein and Taylor Kohut completely misrepresent their solitary bit of “evidence” to support the article’s core falsehood – that “compulsive pornography viewing” was excluded from the new ICD-11 “Compulsive Sexual Behavior Disorder” diagnosis. Part 2 exposes the startling omissions, false claims, research […]

Debunking a July, 2018 article by Gavin Evans: “Can Watching Too Much Porn Give You Erectile Dysfunction?” (Men’s Health)

Introduction Unfortunately YBOP must thoroughly debunk yet another Men’s Health propaganda piece denying porn-induced sexual dysfunctions. The current article mirrors another misleading article YBOP debunked just a few months ago: Debunking “Should you be worried about porn-induced erectile dysfunction?” – by The Daily Dot’s Claire Downs. (2018). Before I address specific assertions, here are the […]

Experts who recognize & treat porn-induced sexual dysfunctions

See this page for the many studies linking porn use or porn/sex addiction to sexual problems and relationship & sexual dissatisfaction (the first 5 studies demonstrate causation as participants eliminated porn use and healed chronic sexual dysfunctions): Since 2011, when urology professor Carl Foresta first described porn-induced sexual dysfunctions, over 120 sexual experts (urology professors, […]

Debunking “Should you be worried about porn-induced erectile dysfunction?” – by The Daily Dot’s Claire Downs. (2018)

Introduction Here we have yet another propaganda piece, this one attempting to deny the existence of widespread porn-induced sexual problems. This one is by The Daily Dot’s Claire Downs whose expertise is described as “A third-generation worker in the Chicago futures industry, she specializes in cryptocurrencies and altcoins.” Interestingly, none of the recent hit pieces […]

Analysis of “A Profile of Pornography Users in Australia: Findings From the Second Australian Study of Health and Relationships” (2016)

COMMENTS: Many claim this study supports the argument that Internet porn doesn’t really cause serious problems. For example, this pro-porn advocate falsely states that only 2% of participants felt that porn was leading to adverse effects. In reality, 17% of males & females aged 16-30 reported that using pornography had a bad effect on them. […]

Critique of “Is Pornography Really about “Making Hate to Women”? Pornography Users Hold More Gender Egalitarian Attitudes Than Nonusers in a Representative American Sample” (2016)

The authors of this study framed egalitarianism as: (1) Support for abortion, (2) Feminist identification, (3) Women holding positions of power, (4) Belief that family life suffers when the woman has a full-time job., and oddly enough (5) Holding more negative attitudes toward the traditional family. Secular populations, which tend to be more liberal, have far higher […]

Dismantling the “group position” paper opposing porn and sex addiction (November, 2017)

Introduction In early November, 2017 three non-profit kink organizations (Center for Positive Sexuality, National Coalition for Sexual Freedom, and The Alternative Sexualities Health Research Alliance) released a group position paper “opposing the addiction model in relation to frequent sexual behavior and pornography viewing.” The groups’ press release, Position statement opposing sex/porn addiction model, explained their […]

Is Utah #1 in Porn Use?

UPDATE: The points made below have now been affirmed in peer-reviewed research. In Social Desirability Bias in Pornography-Related Self-Reports: The Role of Religion (2017), Dr. Joshua Grubbs tested his hypothesis that religious individuals are more likely to lie about their porn use (in anonymous surveys studies or to researchers). The “religious people are lying” hypothesis […]

Porn studies involving female subjects: Effects on arousal, sexual satisfaction, and relationships

While a handful of studies report little effect of women’s porn use on women’s sexual and relationship satisfaction, the vast maturity do report negative effects. This page contains studies linking female porn use to lower sexual or relationship satisfaction. When evaluating the research, it’s important to know that a relatively small percentage of all coupled […]

Nicole Prause’s Harassment, Cyber-stalking, Defamation, and “Astroturf” Campaign

Introduction This page was created to counter the ongoing harassment and false claims made by former UCLA researcher Nicole Prause as part of an ongoing “astroturf” campaign to persuade people that anyone who disagrees with her conclusions deserves to be reviled. Watch this short, excellent TEDx talk, “Astroturf and manipulation of media messages” | Sharyl […]

Study invalidates the CPUI-9 as an instrument to assess either “perceived pornography addiction” or actual pornography addiction (2017)

SECTION 1: Introduction A new study (Fernandez et al., 2017) tested and analyzed the CPUI-9, a purported “perceived pornography addiction” questionnaire developed by Joshua Grubbs, and found that it couldn’t accurately assess “actual porn addiction” or “perceived porn addiction” (Do Cyber Pornography Use Inventory-9 Scores Reflect Actual Compulsivity in Internet Pornography Use? Exploring the Role […]

Studies linking porn use to “un-egalitarian attitudes” toward women

This page collects findings that falsify the popular sexology claim that porn use promotes egalitarian attitudes toward women. Let’s begin with the 2016 study that inspired the creation of this page -“Is Pornography Really about “Making Hate to Women”? Pornography Users Hold More Gender Egalitarian Attitudes Than Nonusers in a Representative American Sample“. It has […]

Studies linking porn use to poorer mental-emotional health & poorer cognitive outcomes

Many individuals who cease using porn for an extended period of time report mental and cognitive benefits, such as improved concentration and focus, better grades, increased energy and motivation, social anxiety improved or gone, increased confidence, improved mood, depression reduced or gone, greater desire to be social, more intense or vibrant emotions, and increased desire […]

Link to original study – Conscious and Non-Conscious Measures of Emotion: Do They Vary with Frequency of Pornography Use? (2017) Comments: This 2017 EEG study on porn users cited 3 Nicole Prause EEG studies.

Critique of: “Damaged Goods: Perception of Pornography Addiction as a Mediator Between Religiosity and Relationship Anxiety Surrounding Pornography Use” (Leonhardt, Willoughby, & Young-Petersen, 2017)

The “perceived pornography addiction” meme continues to infect the peer-reviewed literature, this time in a new study: “Damaged Goods: Perception of Pornography Addiction as a Mediator Between Religiosity and Relationship Anxiety Surrounding Pornography Use“, 2017 (Leonhardt, et al.). The phrase “perceived pornography addiction” was promoted by Joshua Grubbs, and first used in his 2013 study. […]

Is Joshua Grubbs pulling the wool over our eyes with his “perceived porn addiction” research?

INTRODUCTION A new concept has recently appeared in a rash of papers and articles: “perceived porn addiction.” It was cooked up by Joshua Grubbs and thoroughly examined in the YBOP analysis: Critique of “Perceived Addiction to Internet Pornography and Psychological Distress: Examining Relationships Concurrently and Over Time” (2015). Here are a few of the headlines […]

Op-ed: Who exactly is misrepresenting the science on pornography?

8 neuroscientists fail to cite a single neuroscience study to support their claims By Clay Olsen, Gail Dines, Mary Anne Layden, Gary Wilson, Jill Manning, Donald Hilton and John Foubert Charges of misrepresenting science are serious. We write in response to a recent op-ed’s critique of Fight the New Drug’s scientific claims. Rather than mere […]

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

A number of articles and interviews have attempted to pushback at the TIME article (“Porn and the Threat to Virility”) and the Utah resolution declaring internet porn a public health problem. What might be a few “dead giveaways” that such an article is nothing more than a propaganda piece? Psychologists David Ley and/or Nicole Prause […]

Debunking the debunker: Critique of letter to the editor “Prause et al. (2015) the latest falsification of addiction predictions”

Introduction: In various comments, articles and tweets Nicole Prause has claimed that not only did Prause et al., 2015 falsify “a core tenet of the addiction model, the cue reactivity biomarker,” but that “a series of behavioral studies replicated by independent laboratories [falsify] other predictions of the addiction model.” Prause cites the Letter to the […]

Analysis of “Perceived Effects of Pornography on the Couple Relationship: Initial Findings of Open-Ended, Participant-Informed, Bottom-Up Research” (2017)

Update: In this 2018 presentation Gary Wilson exposes the truth behind 5 questionable and misleading studies, including this study (Kohut et al., 2017): Porn Research: Fact or Fiction? COMMENTS: Is the intention behind this Taylor Kohut study to (attempt to) counter the nearly 60 studies that show porn use has negative effects on relationships? The […]

Critique of: “Is Pornography Use Associated with Sexual Difficulties and Dysfunctions among Younger Heterosexual Men?” (2015)

UPDATE 1: Comment on: Is Pornography Use Associated with Sexual Difficulties and Dysfunctions among Younger Heterosexual Men? by Gert Martin Hald, PhD UPDATE 2: Landripet & Stulhofer’s paper omitted two significant correlations they presented to a European conference: Reporting a preference for specific pornographic genres were significantly associated with erectile (but not ejaculatory or desire-related) […]

Link to PubMed version by Gert Martin Hald Article first published online: 14 MAY 2015 J Sex Med 2015;12:1140–1141 Surprisingly, given its potential clinical relevance, very few studies have attempted to investigate relationships between pornography consumption and common sexual dysfunctions and problems (in the following referred to as “sexual difficulties”). When having done so, the […]

Studies linking porn use/sex addiction to sexual problems, lower arousal to sexual stimuli, and less sexual & relationship satisfaction

Regardless of what you may read in some journalistic accounts, multiple studies reveal a link between porn use and sexual performance problems, relationship and sexual dissatisfaction, and reduced brain activation to sexual stimuli. Let’s start with sexual dysfunctions. Studies assessing young male sexuality since 2010 report historic levels of sexual dysfunctions, and startling rates of […]
