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. […]

Studies Report Escalation (and Habituation) in Porn Users

Compulsive porn users often describe escalation in their porn use that takes the form of greater time viewing or seeking out new genres of porn. New genres that induce shock, surprise, violation of expectations or even anxiety can function to increase sexual arousal, and in porn users whose response to stimuli is growing blunted due […]

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 20 Neurological Studies Supporting Porn Addiction

Several recent 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 (one example). What might be a few “dead giveaways” that such an article is nothing more than a propaganda piece? Psychologists David Ley and/or Nicole […]

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” (2016)

COMMENTS: Is the intention behind this study to (attempt to) counter the many studies that show porn use has negative effects on relationships? The two main problems with this study are: It does not contain a representative sample. Whereas most studies show that a tiny minority of porn users’ partners use porn, in this study […]

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) […]

Comment on: “Is Pornography Use Associated with Sexual Difficulties and Dysfunctions among Younger Heterosexual Men?” by Gert Martin Hald PhD (2015)

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 […]

Should compulsive sexual behavior be considered an addiction? (2016): Excerpt analyzing “Prause et al., 2015”

Link to original paper – Should compulsive sexual behavior be considered an addiction? (2016) COMMENTS: This review, like the other papers, says that Prause et al., 2015 aligns with Kühn & Gallinat, 2014 (Citation 72) which found that more porn use correlated with less brain activation in response to pictures of vanilla porn. In other […]

Neurobiology of Compulsive Sexual Behavior: Emerging Science (2016): Analyzes Prause et al., 2015

COMMENTS: While this paper (below) is only a brief summation, it contains a few key observations. For example, it states that both Prause et al., 2015 and Kuhn & Gallinat, 2014 report a similar finding: greater porn use correlating with greater habituation to porn. Both studies reported lower brain activation in response to brief exposure […]

Research confirms sharp rise in youthful sexual dysfunctions

Young men today appear to be experiencing a sharp increase in ED (and other sexual dysfunctions) since the advent of streaming internet. All studies assessing young male sexuality since 2010 report historic levels of erectile dysfunction, and startling rates of a new scourge: low libido. Erectile dysfunction rates ranged from 14 to 33%, while rates […]

Lindberg (Grubbs et al.): Watching Porn Is OK. Believing In Porn Addiction Is Not Perceived Addiction To Porn Is More Harmful Than Porn Use Itself Believing You Have […]

Current List of Brain Studies on Porn Users

Listed below are all the “brain” studies on porn users currently published (or in the press). These study results are consistent with 210+ Internet addiction brain studies, some of which also include internet porn use. In short, there’s ample (and growing) peer-reviewed scientific support for the addiction model. All support the premise that internet porn […]

Analysis of “Modulation of late positive potentials by sexual images in problem users and controls inconsistent with ‘porn addiction’ (2015)”, by SPAN Lab

Published July 2015, we will refer to it as Prause, et al., 2015. Contrary to claims Prause’s 2015 EEG study supports the porn addiction model, as it reports habituation (or desensitization) in the more frequent porn users. To date 5 peer-reviewed analyses by neuroscientists and medical doctors agree with the following critique – that Prause […]

Is there evidence supporting the existence of pornography addiction?

Yes, according to Donald L Hilton, MD, author of “Pornography addiction – a supranormal stimulus considered in the context of neuroplasticity” in Socioaffective Neuroscience & Psychology. But one needs the perspective and education to understand the supporting evidence—and why it will eventually overtake the competing viewpoint that compulsive porn use is due to “hypersexual disorder,” […]
