Studies Linking Porn Use to Sexual Offending, Sexual Aggression, and Sexual Coercion

April 11, 2020/0 Comments/in Uncategorized /by psadmin

The following studies link porn use to sexual offending, sexual aggression, and sexual coercion (listed by date of publication):

But haven’t rape rates declined since the advent of Internet porn?

Have you heard the often repeated claim (by porn sites and pro-porn activists) that “porn use has dramatically lowered rape rates?”According to new statistics released by the FBI (excerpt below), the number of rapes (per 100,000 of the population) has steadily increased from 2014-2016 (the last year for which stats are available). In the UK, there were 138,045 sex offenses, up 23%, in the 12 months preceding September, 2017.

But didn’t rape rates decline since the advent of internet porn? In some countries yes, and in others no. The claim that widespread porn availability is correlated with a decline in rape rates is based only on the nationwide data from a few selected developed nations. As expanded on in the following 5 sections, these claims comprise a house of cards, which ignore conflicting data and important variables, such as:

Developed countries have experienced a decline (per 100K of the population – the unit usually used for determining rape rates) in the age group most likely to commit sexual crimes (12-34) as the population aged.
Studies reveal that rape rates are often under-reported – and may in fact be on the rise in the last 20 years.
Several countries have reported an increase in rape rates during this same period.
Rates of sexual offenses are rising in the US and United Kingdom (two of the biggest users of Pornhub).
Studies assessing actual porn users show a link between porn and increased sexual violence, aggression and coercion (reviews of the literature and meta-analyses).
US rates for all violent crimes peaked around 1990, and then declined until about 2013, when rape rates started to rise. Important to note that rape rates declined the least (of the crime categories) while others declined.

On to addressing the propaganda:

#1 – What about other variables related to violent crime rates?

Correlation doesn’t equal causation. Numerous other variables likely account for the decline in reported rapes in select countries. The most obvious variable playing a role is that developed countries have experienced a decline (per 100K of the population) in the age group most likely to commit sexual crimes (12-34) as the population aged. As you can see in the graph, US rates for all violent crimes peaked around 1990, and then declined until about 2013, when rape rates started to rise. Important to note that rape rates declined the least (of the crime categories) during this period:

The decline in violent crime coincided with an increase in percentage of aged members per 100K of the population, and a corresponding decrease in the age group most likely to commit violent crime. This demographic shift has occurred in many “first world” nations. First, the 1990 population distribution by age. Note the population in the 15-44 age ranges.

Next, the 2015 population distribution by age. Notice the decline in the age groups most likely to commit violent crimes, and how old folks make up a much larger percentage of the population.

The above demographic shifts could account for the decrease in reported rape rates per 100K of the population, if the rates in fact declined (a claim disputed by some experts). Researcher Neil Malamuth responded on a major sexology listserve to Milton Diamond’s dated papers (touted by some sexologists as proof of their reckless claims):

The Aggregate Issue — Intuitively, it appears to make a lot of sense that the critical “bottom line” is what appears to be happening in the “real world” (e.g., rates of violent crime) as media violence and/or pornography consumption have increased over the years. I think that on the contrary, the problems with looking at this are great and it is virtually impossible to come to any cause and effect conclusions by looking at the aggregate data. For example, consider the following association: The number of guns in the US and the rates of crime. As revealed in the following article Pew: Homicide Rates Cut in Half Over Past 20 Years (While New Gun Ownership Soared) as the number of guns in the US has increased dramatically over the past twenty years, the rates of homicide have dramatically decreased. How many of us are willing to conclude therefore that the wide availability of guns is actually a very good thing and has contributed to the reduction in homicide, as some indeed would be quick to conclude? Drew Kingston and I discuss this aggregate issue more extensively in the following: Problems with Aggregate Data and the Importance of Individual Differences in the Study of Pornography and Sexual Aggression (2010).

The cross-cultural aggregate data regarding pornography use and crime (e.g., Mickey Diamond’s important work) have been obtained, to my knowledge, only in Denmark and in Japan. In those two countries, there has generally been a very low rate of known sexually violent crime. We might expect based on that data as well as several other sources of data that in these countries, there are relatively few men with risk for committing sexual aggression (within the culture and in non-wartime conditions). Therefore, in the context of the Confluence Model’s predictions, in such countries we would actually predict little or no increase in sexual aggression as the availability of pornography increases, as Diamond and associates have reported. Remember, that the men who we have studied in the USA who similarly have low risk have not shown any increased proclivity even with high pornography use. As a critical test, as I noted before, Martin Hald and I did find that even in Denmark, men with relatively higher risk did in fact show greater attitudes accepting of violence against women as a function of both experimental exposure in lab and in“real world” association (see 2015 publication). I would be very interested to see what would happen if a huge change occurred in the availability of pornography in countries with a relatively large percentage of men with high proclivity and associated, sexism, attitudes accepting of violence against women, hostility towards women, etc.).

Moreover, rates of known crime may not be the only “dependent variable” to examine (see below). Although Japan’s adjudicated rates of violence against women are indeed relatively very low (and my limited experience many years ago while visiting Japan suggested that women felt safe walking streets at night) the highest documented rates of rape ever were committed in a single day were by Japanese men (in China in the city of Nanking). Thus, once the culture sanctioned the violence, potential proclivities may have become very evident. Further, in current Japan, there appear to be other manifestations of what may be considered sexual aggressive proclivities and related acts and attitudes towards women (e.g., back in 2000, special train cars were introduced for women to combat men’s groping (chikan).

The “Dependent Variable” Issue

As I mentioned earlier, the Confluence Model focuses on sexually aggressive attitudes and behaviors in men in the general population, particularly college students. Virtually none of the participants we have studied have ever been adjudicated. Known crime rates are therefore somewhat irrelevant. As part of the discussion of the applicability of the model, we have suggested over the years that when it comes to convicted individuals, the model has less relevance as it appears that with such men“general anti-sociality characteristics” have far more direct relevance. These convicted men are often not “specialists” but much more likely to commit a wide variety of crimes. Measures that have consistently shown their utility in the prediction of the sexual aggressors we study, (hostility towards women, attitudes supporting violence against women, etc.) have not as consistently been found to be predictive for known criminals in this area. Although changes in rates of sexual aggression among students would be relevant, it is far from clear whether these have actually increased or decreased over the years or whether there has just been more attention to the matter (I would guess the latter is important). This also relates to the “aggregate problem”: While availability of pornography has increased dramatically over the years, at the same time there has been much more intervention to reduce sexual assault and increase relevant awareness.

Almost every university in the nation now has mandated interventions for all freshman, something that was not the case years ago. Assuming the some media influences may contribute to some increased proclivity to sexual aggression, how can we possibly disentangle the corresponding increases in public awareness of the issue of sexual aggression and actual interventions occurring at much of the same time?

The sexology list-serve discussion continued. Here’s what Neil Malamuth said about Diamond’s study (“You Wrote” is questioner, response is Malamuth):

Pornography use and sex crimes: I think that many people seem to have the impression that the correlational country wide research has shown an inverse correlation between porn use and rape. I don’t believe this is true at all. If you go to Milton Diamond’s own site you can see that once the data is separated between child sex abuse and rape, it is clear that the latter did not decrease (but also did not increase) as porn became more available. Furthermore you can see that there are examples of countries where at least cross-sectionally, there is a high positive correlation between the two. For example, there is an article there indicating that,

“Papua New Guinea, is the most pornography-obsessed country in the world, according to Google Trends. PNG has a population of less than 8 million people and low rates of internet use, but has the greatest percentage of searches for the words “porn” and “pornography” compared to the nation’s total searches. A study published in The Lancet reported that 59 percent of the men in PNG Autonomous Region of Bougainville had raped their partner and 41 per cent had raped a woman who was not their partner.

In addition, the article indicates that Top ten countries searching for ‘pornography’: Google Trends
1. Papua New Guinea
2. Zimbabwe
3. Kenya
4. Botswana
5. Zambia
6. Ethiopia
7. Malawi
8. Uganda
9. Fiji
10. Nigeria

I would guess that among these may also be countries with high rates of sexual and other forms of violence against women. Please note that I am not arguing that pornography is “the” or even “a” cause but rather against the common belief that world-wide or longitudinally that an inverse association has been demonstrated between porn use and rape. It would be interesting to conduct a study that looked cross-culturally at the association after controlling statistically for the risk factors of the Confluence Model, particularly Hostile Masculinity. I would predict that in those countries with high levels of risk, there is a positive correlation between porn use and rape (particularly among men generally rather than only adjudicated crimes) but no correlation or an inverse one in countries with relatively few men who are at risk according to the Confluence Model.

YOU WROTE: at a society level, pornography may indeed have a positive effect on adjudicated sex crimes

RESPONSE: As I indicated before, I don’t believe the Diamond’s and related data reveal what is often assumed about sex crimes generally. As Diamond and colleagues have themselves noted, the data show an inverse relationship between pornography availability and child sex abuse. There is no similar significant association generally between pornography and rape. The causes of rape and the characteristics of rapists vs. child abusers are often quite different and should not be lumped together. In addition, the data are correlational at the country level generally and require much caution about causal relationships, partly due to the “aggregate problem” (Kingston & Malamuth, 2011). What can be concluded with confidence is that for the countries studied, there is no general increase in rape when pornography laws are changed to allow greater availability of pornography. Also, it is important to keep in mind that it appears that all of the countries studied by Diamond and associates appear to be ones that may have relatively few men who are at relatively high risk for committing sexual aggression. I hadn’t previously looked up Croatia, but a quick google search indicates that 94% do not agree with the statement that women should tolerate violence in order to keep the family together.

YOU WROTE: but, within that society wide access there are men exposed to porn where porn increases risk of sex violence, due to a confluence of risk factors

RESPONSE: largely consistent with what you wrote but phrased somewhat differently: for men in the general population who have relatively high levels on the “key” risk factors, the data strongly indicate that “heavy” use of porn may increase sexually violent attitudes and behavioral inclinations.

YOU WROTE: societies which allow porn access may be engaging in a trade off, accepting a small amount of increased risk in a small group for a larger amount of decreased risk across the larger population

RESPONSE: I think we have to be careful about making generalizations about societies without taking into consideration the contextual differences among them. I would guess that changing pornography laws in Saudi Arabia vs. Denmark would have had very different consequences. Also, I think that focusing only or primarily on adjudicated sex crimes, particularly rape, may be a problem. For example, as we have written elsewhere, Japan is often used as one of the prime examples of countries where pornography is widely available (including “violent” porn) and rates of rape are very low now and historically. Japan is indeed a country that has had strong socialized inhibitions against “within group” violence against women. Yet, consider other potential manifestations: “Groping in crowded commuter trains has been a problem in Japan: according to a survey conducted by Tokyo Metropolitan Police and East Japan Railway Company, two-thirds of female passengers in their 20s and 30s reported that they had been groped on trains, and the majority had been victimized frequently.” When violence against women has been tolerated, it has been extremely high (e.g., see Chang, *The Rape of Nanking*,). Although I am not necessarily disagreeing with your suggestion, I am not sure we can reach such a conclusion at this time.

Put simply, relying on two sets of nationwide data (reported sex crimes and estimated porn availability) from a handful of countries (while ignoring hundreds of other countries), to support a claim that more porn definitively leads to fewer sexual offenses, doesn’t fly among true scientists.

Another important variable revolves around the (in)accuracy of statistics related to sexual crimes.

#2 – Studies reveal that rape rates are often under-reported – and may in fact be on the rise.

It’s important to keep in mind that the crime of rape is consistently under-reported. Even reports to police may be wildly off, as this paper by a US law professor suggests: How to Lie with Rape Statistics: America’s Hidden Rape Crisis (2014).

Using this novel method to determine if other municipalities likely failed to report the true number of rape complaints made, I find significant undercounting of rape incidents by police departments across the country. The results indicate that approximately 22% of the 210 studied police departments responsible for populations of at least 100,000 persons have substantial statistical irregularities in their rape data indicating considerable undercounting from 1995 to 2012. Notably, the number of undercounting jurisdictions has increased by over 61% during the eighteen years studied.

Correcting the data to remove police undercounting by imputing data from highly correlated murder rates, the study conservatively estimates that 796,213 to 1,145,309 complaints of forcible vaginal rapes of female victims nationwide disappeared from the official records from 1995 to 2012. Further, the corrected data reveal that the study period includes fifteen to eighteen of the highest rates of rape since tracking of the data began in 1930. Instead of experiencing the widely reported “great decline” in rape, America is in the midst of a hidden rape crisis.

#3 – Multiple countries have reported an increase in rape rates during this same period.

For example, studies from Spain and Norway report findings that contradict Diamond’s claims (all omitted by the sexologists attempting to promulgate the claim that porn decreases rape):

Is sexual violence related to Internet exposure? Empirical evidence from Spain (2009) – Excerpt: Using a panel data approach for the provinces of Spain during the period 1998-2006, outcomes indicate that there is a substitution between rape and Internet pornography, while Internet pornography increases other violent sexual behaviors, such as sexual assaults.
Broadband Internet: An Information Superhighway to Sex Crime? (2013) – Excerpt: Does internet use trigger sex crime? We use unique Norwegian data on crime and internet adoption to shed light on this question. A public program with limited funding rolled out broadband access points in 2000–2008, and provides plausibly exogenous variation in internet use. Our instrumental variables estimates show that internet use is associated with a substantial increase in both reports, charges and convictions of rape and other sex crimes. Our findings suggest that the direct effect on sex crime propensity is positive and non-negligible, possibly as a result of increased consumption of pornography.

Take a look at this table of rape rates and you will see there’s no real global pattern (indicating a problem with gathering accurate statistics). One thing is for certain, Diamond omitted numerous “modern” countries where both the availability of porn and rape rates have concurrently increased, such as Norway, Sweden, Costa Rica, New Zealand, Iceland, Italy, Argentina, Portugal, etc.

#4 – Rates of sexual offenses rising in the US and United Kingdom (two of Pornhub’s biggest users)

According to new statistics released by the FBI (see graph), the number of rapes (per 100,000 of the population) has steadily increased from 2014-2016 (the last year for which stats are available). In the UK, there were 138,045 sex offenses, up 23%, in the 12 months preceding September, 2017. Yet, during those same periods:

the population has continued to age,
ED rates for men under 40 have skyrocketed, and
overall rates of sexual activity have steadily dropped, as have fertility rates in the West.

#5 –Studies assessing actual porn users show a link between porn and increased sexual violence, aggression and coercion (reviews of the literature and meta-analyses).

Instead of dubious aggregate studies on a few select (cherry-picked?) countries, how about studies on actual porn users that controlled for relevant variables?

A meta-analysis summarizing the effects of pornography II: Aggression after exposure (1995) – Excerpt:

Conducted a meta-analysis of 30 studies, published 1971–1985, to examine the effect of exposure to pornography on aggressive behavior under laboratory conditions, considering a variety of moderating conditions (level of sexual arousal, level of prior anger, type of pornography, gender of S, gender of the target of aggression, and medium used to convey the material).

Results indicate that pictorial nudity induces subsequent aggressive behavior, that consumption of material depicting nonviolent sexual activity increases aggressive behavior, and that media depictions of violent sexual activity generate more aggression than those of nonviolent sexual activity. No other moderator variable produced homogeneous findings.

Pornography and sexual aggression: are there reliable effects and can we understand them? (2000)– Excerpt:

In response to some recent critiques, we (a) analyze the arguments and data presented in those commentaries, (b) integrate the findings of several metaanalytic summaries of experimental and naturalistic research, and (c) conduct statistical analyses on a large representative sample. All three steps support the existence of reliable associations between frequent pornography use and sexually aggressive behaviors, particularly for violent pornography and/or for men at high risk for sexual aggression. We suggest that the way relatively aggressive men interpret and react to the same pornography may differ from that of nonaggressive men, a perspective that helps integrate the current analyses with studies comparing rapists and nonrapists as well as with cross-cultural research.

A meta-analysis of the published research on the effects of pornography (2000) – Excerpt:

A meta-analysis of 46 published studies was undertaken to determine the effects of pornography on sexual deviancy, sexual perpetration, attitudes regarding intimate relationships, and attitudes regarding the rape myth. Most of the studies were done in the United States (39; 85%) and ranged in date from 1962 to 1995, with 35% (n=16) published between 1990 and 1995, and 33% (n=15) between 1978 and 1983. A total sample size of 12,323 people comprised the present meta-analysis. Effect sizes (d) were computed on each of the dependent variables for studies which were published in an academic journal, had a total sample size of 12 or greater, and included a contrast or comparison group. Average unweighted and weighted d’s for sexual deviancy (.68 and .65 ), sexual perpetration (.67 and .46), intimate relationships (.83 and .40), and the rape myth (.74 and .64) provide clear evidence confirming the link between increased risk for negative development when exposed to pornography. These results suggest that the research in this area can move beyond the question of whether pornography has an influence on violence and family functioning.

The role of pornography in sexual offending (2007) – Excerpt:

Research and the Behavioral Effects Associated with Pornography

For Weaver (1993), the controversy stems from three theories of the consequences of exposure to pornography:

The representation of sexuality as a form of learning in view of the social dogma related to what has long been denied or hidden (liberalization)— inhibition, guilt, puritanical attitudes, fixation on sexuality, all of which can be partly eliminated through pornography (Feshbach, 1955).2 Kutchinsky (1991) reiterated this idea, stating that the rate of sexual assault dropped when pornography was made more readily available, serving as a kind of safety valve that eases sexual tensions and thus reduces the rate of sexual offences. Although highly debatable, what this premise means is that pornography offers a form of learning which, according to the author, offsets the acting out. It is debatable because this argument is also used by proponents of the liberalization of prostitution as a way of potentially reducing the number of sexual assaults (McGowan, 2005; Vadas, 2005). That way of thinking undermines human dignity and what it means to be a person. The bottom line is that people are not commodities;

The dehumanization of the person, in contrast to the preceding theory, and where pornography is first and foremost men’s misogynistic image of women (Jensen, 1996; Stoller, 1991);

Desensitization through an image that is not in line with reality. Simply put, pornography offers a highly reductionist view of social relationships. Because the image is nothing more than a series of explicit, repetitive and unrealistic sexual scenes, masturbation to pornography is part of a series of distortions and not a part of reality. Those distortions can be compounded by dynamic and static criminogenic variables. Frequent exposure desensitizes the person by gradually changing his values and behaviour as the stimuli become more intense (Bushman, 2005; Carich & Calder, 2003; Jansen, Linz, Mulac, & Imrich, 1997; Malamuth, Haber, & Feshbach, 1980; Padgett & Brislin-Slutz, 1989; Silbert & Pines, 1984; Wilson, Colvin, & Smith, 2002; Winick & Evans, 1996; Zillmann & Weaver, 1999).

In short, the research carried out to date has not clearly shown a direct cause-and-effect link between the use of pornographic material and sexual assault, but the fact remains that many researchers agree on one thing: Long-term exposure to pornography material is bound to disinhibit the individual. This was confirmed by Linz, Donnerstein and Penrod in 1984, then Sapolsky the same year, Kelley in 1985, Marshall and then Zillmann in 1989, Cramer, McFarlane, Parker, Soeken, Silva, & Reel in 1998 and, more recently, Thornhill and Palmer in 2001, and Apanovitch, Hobfoll and Salovey in 2002. On the basis of their work, all of these researchers concluded that long-term exposure to pornography has an addictive effect and leads offenders to minimize the violence in the acts they commit.

Pornography and attitudes supporting violence against women: revisiting the relationship in nonexperimental studies (2010) – Excerpt:

A meta-analysis was conducted to determine whether nonexperimental studies revealed an association between men’s pornography consumption and their attitudes supporting violence against women. The meta-analysis corrected problems with a previously published meta-analysis and added more recent findings. In contrast to the earlier meta-analysis, the current results showed an overall significant positive association between pornography use and attitudes supporting violence against women in nonexperimental studies. In addition, such attitudes were found to correlate significantly higher with the use of sexually violent pornography than with the use of nonviolent pornography, although the latter relationship was also found to be significant. The study resolves what appeared to be a troubling discordance in the literature on pornography and aggressive attitudes by showing that the conclusions from nonexperimental studies in the area are in fact fully consistent with those of their counterpart experimental studies. This finding has important implications for the overall literature on pornography and aggression.

Sex industry exposure over the life course on the onset and frequency of sex offending (2014) – Excerpts:

Research has examined pornography use on the extent of offending. However, virtually no work has tested whether other sex industry experiences affect sex crime. By extension, the cumulative effect of these exposures is unknown. Social learning theory predicts that exposure should amplify offending.

Drawing on retrospective longitudinal data, we first test whether exposure during adolescence is associated with a younger age of onset; we also examine whether adulthood exposure is linked with greater frequency of offending.

Findings indicate that most types of adolescent exposures as well as total exposures were related to an earlier age of onset. Exposure during adulthood was also associated with an overall increase in sex offending, but effects were dependent on “type.”

A Meta‐Analysis of Pornography Consumption and Actual Acts of Sexual Aggression in General Population Studies (2015). – Excerpt:

Meta‐analyses of experimental studies have found effects on aggressive behavior and attitudes. That pornography consumption correlates with aggressive attitudes in naturalistic studies has also been found. Yet, no meta‐analysis has addressed the question motivating this body of work: Is pornography consumption correlated with committing actual acts of sexual aggression? 22 studies from 7 different countries were analyzed. Consumption was associated with sexual aggression in the United States and internationally, among males and females, and in cross‐sectional and longitudinal studies. Associations were stronger for verbal than physical sexual aggression, although both were significant. The general pattern of results suggested that violent content may be an exacerbating factor.

Adolescents and Pornography: A Review of 20 Years of Research (2016) – Excerpt:

The goal of this review was to systematize empirical research that was published in peer-reviewed English-language journals between 1995 and 2015 on the prevalence, predictors, and implications of adolescents’ use of pornography. This research showed that adolescents use pornography, but prevalence rates varied greatly. Adolescents who used pornography more frequently were male, at a more advanced pubertal stage, sensation seekers, and had weak or troubled family relations. Pornography use was associated with more permissive sexual attitudes and tended to be linked with stronger gender-stereotypical sexual beliefs. It also seemed to be related to the occurrence of sexual intercourse, greater experience with casual sex behavior, and more sexual aggression, both in terms of perpetration and victimization.

Predicting the Emergence of Sexual Violence in Adolescence (2017) – Excerpt:

After adjusting for potentially influential characteristics, prior exposure to parental spousal abuse and current exposure to violent pornography were each strongly associated with the emergence of SV perpetration-attempted rape being the exception for violent pornography. Current aggressive behavior was also significantly implicated in all types of first SV perpetration except rape. Previous victimization of sexual harassment and current victimization of psychological abuse in relationships were additionally predictive of one’s first SV perpetration, albeit in various patterns. In this national longitudinal study of different types of SV perpetration among adolescent men and women, findings suggest several malleable factors that need to be targeted, especially scripts of inter-personal violence that are being modeled by abusive parents in youths’ homes and also reinforced by violent pornography.

The Impacts of Sexual Media Exposure on Adolescent and Emerging Adults’ Dating and Sexual Violence Attitudes and Behaviors: A Critical Review of the Literature (2017) – Abstract:

Dating violence (DV) and sexual violence (SV) are widespread problems among adolescents and emerging adults. A growing body of literature demonstrates that exposure to sexually explicit media (SEM) and sexually violent media (SVM) may be risk factors for DV and SV. The purpose of this article is to provide a systematic and comprehensive literature review on the impact of exposure to SEM and SVM on DV and SV attitudes and behaviors. A total of 43 studies utilizing adolescent and emerging adult samples were reviewed, and collectively the findings suggest that:

(1) exposure to SEM and SVM is positively related to DV and SV myths and more accepting attitudes toward DV and SV;

(2) exposure to SEM and SVM is positively related to actual and anticipated DV and SV victimization, perpetration, and bystander nonintervention;

(3) SEM and SVM more strongly impact men’s DV and SV attitudes and behaviors than women’s DV and SV attitudes and behaviors; and

(4) preexisting attitudes related to DV and SV and media preferences moderate the relationship between SEM and SVM exposure and DV and SV attitudes and behaviors.

We conclude with another post from a major sexology listserve discussion of porn and sexual offenses/aggression. As you will see, the author is pro-porn (and a PhD sex researcher):

I think that the general statement I made does stand for sexual aggression as well as for the other outcome variables. At this point, in addition to a) correlational data showing greater exposure to porn linked to all sorts of sexual and nonsexual aggressive attitudes and behaviors, we also have:

b) experimental data showing that exposure to porn increases nonsexual aggression in the lab (things like physical, material, or psychological aggression like the administration of electric shocks) (33 studies meta-analyzed in Allen, D’Alessio, & Brezgel, 1995);

c) experimental data showing exposure to porn increases attitudes supportive of sexual violence (acceptance of interpersonal violence, rape myth acceptance, and sexual harassment proclivities) (16 studies meta-analyzed in Emmers, Gebhardt, & Giery, 1995);

d) longitudinal evidence that watching more porn at Time 1 is linked to more acts of real-life sexual aggression at Time 2 (5 studies meta-analyzed in Wright, Tokunaga, & Kraus, 2015), even after controlling for many potential confounding factors, including sexual victimization, substance use, etc.

In light of all this evidence, it is really hard and unreasonable, in my opinion, to argue that the real-life causal links between porn and aggression are somehow not real and completely nonexistent. Yes, a dose of skepticism should remain, and better and more research studies should always continue to be done, but right now, if I was forced to bet, I’d have to say that I’d put my money on there being SOME negative effect of porn on sexual aggression, with that effect likely being a) relatively small, b) limited to a high-risk group of people, and c) much more pronounced for some types of porn (violent) than others (nonviolent but typical mainstream porn) and nonexistent for yet other types of porn (feminist, queer).

Of course, neither experimental nor longitudinal data are perfect for determining causality in the real world, but we all seem to agree that they strongly imply causality when it comes to other areas of psych research. They are our gold standards for establishing causality for all sorts of behavioral outcomes. Why are we so skeptical when it comes to this one area of research? Because it doesn’t suit our desires for porn not to have any negative effects? I’m sorry, but I love porn as much as you all do (I really do), but I cannot justify holding porn to higher standards of proof just because I don’t like the findings. This is what I meant when I said that rejecting or ignoring these findings makes us as blind and ideological about it as the anti-porn crusaders….

…..I didn’t mean to equate us with the anti-porn in how we use the findings and the implications for real-world interventions we draw from them. What I was saying is that just like they do, we seem to be employing some pretty strong confirmation biases to only see what we want to see. But by turning a blind eye to the evidence that keeps mounting, we are compromising our credibility as objective truth-seekers, and we are limiting the impact our position that banning porn is not the solution can have on enacting real-world change. By taking an extreme position (“no kind of porn has any effects on sexual aggression in anyone”) which is not supported by the evidence, we’re making ourselves less relevant and more easily dismissed as just as ideologically driven as the crazies taking the other extreme position (“all porn increases sexual aggression in everyone who watches it”).

Again, don’t get me wrong: I love porn, I watch it all the time, and have zero desire to ban it.

NOTE: YBOP gathered the research on this page to counter the realyourbrainonporn.com so-called “research page.” Porn-industry shill realyourbrainonporn presents a handful of cherry-picked, often irrelevant papers (many are not actual studies), as representative of the current state of the research. Nothing could be further from the truth. These links go to extensive debunking of RealYBOP research-page claims and “sections”:
