Porn. Rape?

I was reading posts on tonight's war-du-jour, porn, and I did a little research. I'm big on looking at outcomes data - in this case, is there evidence that porn causes sexual violence?

Seems to me that porn started becoming reasonably available around 1980, and has steadily increased in accesibility since. I wondered how the incidence of rape has changed during that time. Turns out it's changed a lot: it's dropped by 80%.


Source: http://en.wikipedia.org/wiki/Rape_statistics#United_States

While this doesn't prove - at all - that more porn equals less rape, it does seem to counter any claim that more porn causes more rape.

If anyone has expertise in this area, I'd appreciate your feedback.

"obesity reduces life expectancy" MannyGoldstein May 2014 #83
Umm, that JAMA study you linked to, for one... DanTex May 2014 #89
I find this kind of funny, given that BMI isn't even a good measure of obesity. Kurska May 2014 #90
Sure, that's fine, but the increased mortality even shows up using BMI, evidently. DanTex May 2014 #93
It isn't a weak measure, it is a bad measure. Kurska May 2014 #96
Overweight people had reduced mortality compared to "normals" MannyGoldstein May 2014 #104

Except he never claimed it was causing a decrease in rapes. Also you just used the P word wrong. Kurska May 2014 #95
Yes, the problem is that this isn't "good evidence" of anything. DanTex May 2014 #99
We have a massive increase in porn consumption nationally. Kurska May 2014 #101

No it doesn't hinge on a "choice" of definition. It's *the* definition of correlation. DanTex May 2014 #128

South Africa
Main article: Sexual violence in South Africa


The Criminal Law (Sexual Offences and Related Matters) Amendment Act, 2007 is the relevant legislation in South Africa. Despite the fact that this act provides modern and progressive laws, that ban rape and other forms of sexual abuse, including sexual violence within marriage, South Africa remains a country where sexual attacks are common. The country has some of the highest incidences of child and baby rape in the world with more than 67,000 cases of rape and sexual assaults against children reported in 2000, with welfare groups believing that unreported incidents could be up to 10 times higher.[148] In 2001, a 9-month-old was raped and likely lost consciousness as the pain was too much to bear.[149] Another 9-month-old baby was raped by six men, aged between 24 and 66, after the infant had been left unattended by her teenage mother. A 4-year-old girl died after being raped by her father. A 14-month-old girl was raped by her two uncles. In February 2002, an 8-month-old infant was reportedly gang raped by four men. One has been charged. The infant has required extensive reconstructive surgery. The 8-month-old infant's injuries were so extensive, increased attention on prosecution has occurred.[150] A significant contributing factor for the escalation in child abuse is the widespread myth in HIV-ravaged South Africa that having sex with a virgin will cure a man of AIDS.[151][152] According to official figures, circa 11% of South Africans are infected with the virus.[153] Edith Kriel, a social worker who helps child victims in the Eastern Cape, said: "Child abusers are often relatives of their victims – even their fathers and providers."[151]

One in three of the 4,000 women questioned by the Community of Information, Empowerment and Transparency said they had been raped in the past year.[154] More than 25% of South African men questioned in a survey admitted to raping someone; of those, nearly half said they had raped more than one person, according to a new study conducted by the Medical Research Council (MRC).[155][156] A 2010 study led by the government-funded Medical Research Foundation says that in Gauteng province, more than 37 percent of men said they had raped a woman. Nearly 7 percent of the 487 men surveyed said they had participated in a gang rape.[157] Among children, a survey found 11% of boys and 4% of girls admitted to forcing someone else to have sex with them while in another survey among 1,500 schoolchildren in the Soweto township, a quarter of all the boys interviewed said that 'jackrolling', a term for gang rape, was fun.[148][154]

So this particular posting of yours is an off-topic trolling post.

With the birth rate. A PhD criminologist I worked with told me the number one factor influencing crime is the percentage of young men in the population. The birth rate is down and with it the violent crime rate. Homicide is at its lowest rate in a century.
The percentage of the population raped, however, has not declined.

From Freakenomics is that crime rates have been decreasing because of legal abortion. The percentage of young men who were not wanted babies has probably decreased a huge amount since abortion became legal.

The book is an entertaining read, i'll grant you, and perhaps good fodder for a cocktail party conversation. But to take it as any kind of authoritative analysis of crime (or any other) statistics is, intellectually speaking, highly suspect. The authors point to mere correlation between two factors -- the weakest possible statistical relationship between any two factors, and one which in no way should be construed, absent a whole lot of much more in-depth analysis of many, many other possible factors as well, to be a causative relationship in either direction -- and then proceed to posit their own, explanatory hypothesis of that correlation. It is pretty thin gruel on which to base one's understanding of crime statistics.

Manny clearly says in his OP: "While this doesn't prove - at all - that more porn equals less rape, it does seem to counter any claim that more porn causes more rape." Correlation does not necessarily imply causation (because there may be other unconsidered factors affecting the incidence of either or both), but causation does necessarily imply correlation (because if A causes B, more of A can be expected to cause more of B). Manny employs that principle perfectly by stipulating that the data in the graph cannot be used to infer a causative relationship between a greater availability of porn and a incidence of rape (because correlation, positive or negative, does not establish causation), but noting that if, as anti-porn crusaders sometimes suggest, the greater availability of porn has a causative relationship to a higher incidence of rape, then as that availability increases, one would expect to see a corresponding rise in incidence.

it is a negative correlation but the chart shows a positive correlation.

Just saying.

And look at the numbers for "pirates" it goes 35k, 45k, 20k. But it isn't charted that way. I'm not sure if I even believe those numbers. The golden age of piracy ended in the early 18th century.

Actually the only thing depicted here is temperature x time, not temperature x pirates.

Mon May 19, 2014, 08:23 AM
May 2014
Here is a TLDR: Correlation doesn't prove causation, but causation requires a correlation. That is why the argument he is making here is worthy of consideration.

Correlations can not be used to demonstrate causation. They can be used to infer the possibility of causation, but you're right a correlation alone will not prove causation. However, that isn't what the OP is trying to do.

"While this doesn't prove - at all - that more porn equals less rape, it does seem to counter any claim that more porn causes more rape."

What is that you say? Isn't he trying to prove causation, actually no he isn't. He is using the absence of a correlation to provide evidence AGAINST causation. Which is 100% a sound statistical concept. We do it all the time. Correlations don't prove causation, but causation requires a correlation. If one event causes the other, then there will be a correlation between them. However, just because an event is correlated does not mean that one must cause the other.

Now, absence of a correlation doesn't 100% prove there is not causation (few things actually are "proven" in science). Sometimes the effect of a third variable can interfere with a correlational relationship. It does however show that if there is a relationship, it isn't strong enough to overcome that third variable and it provides pretty damning evidence that needs to be addressed if the counter-argument does want to prove causation. There are ways to control for third variables, both statistically and in experimental design, that will reveal that correlation that is, again, required for a causal relationship to exist. Those are beyond the scope of this current post, however.

If there is a correlation, but that correlation is in STRONGLY IN THE OPPOSITE DIRECTION OF THE PROPOSED CAUSATION, then that provides even stronger evidence against causation (but again does not prove a causal relationship in the opposite direction.

No, causation doesn't actually require an observed correlation. In this case, the only thing that matters is whether the amount of rape there is now is more or less than it would have been without the porn. So, yes, porn can increase rape rates despite this trend.

And there's plenty of examples of equally absurd arguments. For example, obesity has been increasing, and so has life expectancy. Does that counter the argument that "obesity reduces life expectancy". No, of course not.

Since nobody believes that porn is responsible for a huge drop in rape, the only thing this chart proves is that other factors besides porn have greatly reduced rape rates. That's it.

Yes, obesity reduces life expectancy. That we know. On the other hand, obesity has been increasing at the same time as life expectancy. Which means that splashing up graphs of national trends (i.e. what you did in this OP) can easily lead to the wrong conclusion. The national time series correlation is more obesity and longer lives.

Does that disprove that obesity shortens lives? Of course not.

And, in the same way, the fact that rape has dropped while porn has increased doesn't prove or disprove anything.

The population-level time-series correlation between obesity rates and life expectancy is enormous. Very similar to the correlation between increased porn and reduced rape. At the individual level, with obesity, there is a significant correlation in the other direction. With rape, we don't know -- all we can really say is that the population level trends don't mean much.

The point of this is to illustrate the dangers of working with national time-series which are influenced by large numbers of factors, and trying to prove or disprove causal links based on long-term trends.

The reason that evidence isn't compelling is because we've done OTHER research that shows if you control for the third variables at play (improved medical care, work becoming less dangerous, etc...). That obesity does lead to a lower life expectancy.

If we hadn't done that research then that evidence would be compelling and it would need to be explained.

Now show me equivalent research on pornography and rape that has identified the relevant third variables, eliminated them and then demonstrated that people who consume porn are more likely to rape than those who aren't.

The only thing that matters is the other research, whether it exists or not, or what it says. So if this OP had said "there is no research linking rape to porn", that would have been fine. But it didn't.

Instead it made a silly argument from national trends, an argument that, as demonstrated by obesity/life expectancy (and it's easy to come up with other examples), is pretty much useless.

I still don't know if any other research examining the link between rape and porn exists, and what it says.

Since nobody believes that porn is actually responsible for a major part of the reduction in rape rates, all that this proves is that non-porn-related factors have caused rape rates to drop significantly over the last few decades.

That's basically it. It means that national rape trends are so affected by other variables that they don't carry much information about the relationship between porn and rape.

He said the fact that porn use has skyrocketed, yet rapes have bottomed out is good evidence against the claim that porn causes rapes. I agree with that, at minimum it is evidence that needs to be explained if your'e going to go with a causal relationship between porn consumption and increased rape.

Actually you're the one who is adopting the unfounded position here. You're claiming that this proves that something else besides porn is responsible for the decrease in rapes. Now I agree with that, but you're using the word "prove" here which is incredibly tenuous given you've supplied absolutely zero evidence to back up that assumption. I wasn't aware that seeming logical is enough for us to say something is proved.

You're right that I shouldn't have used the word "prove", but I truly think the only thing it, umm, indicates, is that there are significant non-porn factors that have been reducing rape rates.

In fact, unless porn reduces rape (possible, but I don't think many people believe that), then there would have to be other such factors.

So, if we assume the existence of such other factors (which, I agree, I haven't proven), that means that we are looking at a baseline rape time series that drastically decreases. And since we don't know what the other factors are or how strong their effect is, there is effectively no way to try and estimate how much rape there would have been without the increase in porn.

In the end, this means that we are looking at noisy data, and I would stand by the conclusion that a rational person's view of the link between rape and porn should be changed much if at all by this. With maybe one exception -- it does suggest that the link between porn and rape, if it exist, isn't absolutely enormous, i.e. that porn consumption isn't the primary driver of rape. But I don't think many people believed that to begin with.

And that's my problem with the OP. On the surface, it seems to have implications about porn-rape links, but if you think it through, it doesn't.

That is there is a link causal link between more pornography and more rape, it is nowhere near the largest variable driving the number of rapes in our society.

And possibly that people who support that causal link really need to explain what the other variables that are masking the effect of their theorized relationship are.

While he's correct that the given original chart does not actually prove anything other than that IF pornography is correlative with rapes, there are other factors that overwhelm that correlation, making it largely irrelevant in terms of the overall factors that influence the number of rapes that occur, he's wrong in proclaiming that causation will not show correlation, period. In a correctly controlled study that accounts for other factors, causation WILL demonstrate correlation, as you note.

It's especially ironic that he proclaims poor understanding of statistics a 'pet peeve' after making a sweeping statement denying that causation will show correlation as well.

You know, correlation:


There are plenty of examples where the correlation is negative but there is a positive causal link.

If you do the right multivariate regression and control for all the other necessary factors, and causal link exists, then, yes, you will get a positive regression coefficient (usually, although even that assumes that the causal link is linear). But to claim that causation requires correlation is simply wrong.

More to the point, I don't see even an attempt by the OP to do any kind of controlling. In fact, I don't think that the OP even knows what it means to control for confounding variables. I mean, as a very first step, at least examine whether rape rates have dropped more or less than overall violent crime rates. The real mystery is why people are trying to defend this OP with bogus pseudo-statistical arguments.

Correlation is a bivariate statistic. It doesn't depend on the "experimental boundaries". It has a specific definition.

When you measure a correlation between X and Y, you are, by definition, ignoring Z. If you are including Z in your analysis, then you aren't measuring a correlation. You are doing something else, most likely a multivariate regression. The flawedness of an experiment has nothing to do with whether causation requires correlation.

In fact, if causation required correlation, then it wouldn't be possible to design an experiment which finds zero correlation when positive causation exists.

is at this website, but their argument seems to hinge upon their specific choice of a limited definition of 'correlation'.

Since x really does have a causal role in determining the value of y we see that causation can exist without correlation. This result hinges on the precise definition of correlation. It is a specific statistic and reveals only a little bit about how x and y relate. Specifically, if x and y are zero mean and unit variance (which we can assume without loss of generality), correlation is the expected value of their product. That single number can’t possibly tell us everything about how x might relate to y. If we didn’t know the true process y=Ax and the statistics of A in advance we might be tempted to say that x cannot cause y due to a lack of correlation. That would be an incorrect conclusion. Correlation and our lack of understanding of it would be misleading us.

There's no other choice of how to define correlation that would lead to a different conclusion about whether causation can exist without it. Like he says, correlation is a specific statistic.

It's as if you said "on average, women are taller than men", and I said, no, that's not true, and you would say "well that depends on your definition of 'average'." Yeah, if you use "correlation" to mean some other non-scientific thing, then I'm sure you can get to whatever conclusion you want.

Mon May 19, 2014, 10:17 PM
May 2014

I'm not sure what exactly you mean by "appearance of a correlation". Either X and Y are correlated or they aren't. The only meaningful sense of "appearance of correlation" would be a correlation that shows up in sample data simply by chance but doesn't exist in the underlying population, but that's obviously not what we're talking about.

Just as the fact that X and Y are correlated doesn't imply a causal relationship, the fact that X and Y are uncorrelated doesn't imply that there is no causal relationship. In other words, "correlation does not imply causation" and "lack of correlation does not imply lack of causation" are both true.

If you are talking about a "well-designed experiment", then you are talking about a regression coefficient, not a correlation. Yes, you can interpret the coefficient as a correlation, but in that case it won't be a correlation between X and Y, but a correlation between two variables that are derived from X and Y after removing the effects of A, B, C, etc. So, at best, you can claim that "a causal relationship between X and Y implies that a correlation exists somewhere between some two other variables that are related to but not necessarily equal to X and Y".

Of course, if we're talking about the kind of correlation between adjusted variables that come out of a "well designed experiment", then not only does causation imply correlation, but correlation also implies causation (although it doesn't imply the direction of the causation). This is because a well designed experiment is precisely an experiment that controls for all possible confounding variables that could produce the "appearance of correlation" without a causal link. Which means that the argument that "causation requires correlation" is on equal logical footing as the argument that "correlation implies causation".

In any case, since the data presented by the OP doesn't come anywhere close to a well-designed experiment, then, for the purposes of the present discussion "causation does not require correlation" is 100% accurate.


On edit: come to think of it, it even possible that a causal link can exist even if no correlation exists anywhere, even after controlling. This could happen if X has a positive causal effect on Y, while Y has a negative causal effect of equal strength on X. In this case, even after controlling, there still wouldn't be an observed correlation because the causal effects will cancel out. In the current example, this would mean that porn viewing could cause more rape while rapes cause a reduction in porn viewing (or vise versa).

Except you're wrong. Because there is no correlation between pornography and rape, then it is up to the people who are asserting the causational relationship to explain why there isn't one. This technique is used all the time to argue against causation. It is a valid use of statics.

I'm an experimental psychologist, this is part of my job.

The inverse correlation over time between porn and rape doesn't prove or disprove anything. It is nothing more than an interesting observation. Period.

The claim you made that "causation requires a correlation" is basically wrong too. OK, it's technically true that causation requires a correlation to show up after you've controlled for everything else. But it certainly doesn't require a correlation of national time series.

153. That's true, but does/did anyone really believe that porn is the primary cause of rape?
Mon May 19, 2014, 04:15 PM
May 2014

If so, yes, this casts doubt on that hypothesis. Other than that we are left with the possibility that porn either increases, or decreases, or does not affect rape incidence. Which is pretty much where we started.

All snark aside, it would be interesting to see if rates of rape have dropped more or less than rates of other violent crimes. Under the assumption that the other factors affecting rape also affect violent crime rates in general, it would at least be a step towards trying to isolate the effect of porn. It still wouldn't be enough to draw any real conclusions, in either direction, but it would be a little closer.

I think anyone who gives any critical thought to the issues is going to realize that sexual violence arises from a multitude of factors. I would also suggest that while the increasingly sexualized depiction of women in media over the last half century does influence societal attitudes, it probably is less a driver for rape than other, supposedly 'non-pornographic' media.

Violent rape by strangers has never been considered a 'positive' in media, and so is less likely to increase as a result of media portrayals of it. But... there are a lot more rapes of the type portrayed in scores of B movies of the last generation. These 'teen party movies' are not considered pornography, but they have sent years of repetitive messaging that the way 'hookups' in college work is that men get women drunk and then have sex with them. And we don't teach 'relationship ed' in schools, only 'sex ed'.

So young people see dysfunctional messaging about how the sexes should interact in such settings, and we wind up with an epidemic of young women being sexually assaulted and even raped while incapacitated, then not reporting the vast majority of such assaults because they have been taught by movies, television and songs that this is simply 'the way it is'. Media that specifically teaches young men to be sexually aggressive, glorifies such as being 'manly', and constantly ties sex to intoxication has been far more damaging to society than, for instance, depictions of actual sex between adults that occur when both parties are able to give consent and do so.

So I'd say movies like 'Revenge of the Nerds' or songs like 'Blurred Lines' are more damaging to society than many sorts of pornography. (There's certainly an argument to be made that pornography that depicts women as victims or unequal and lesser partners in relationships is damaging, and I would agree with that argument.)

8. One chart from an entire article is very misleading at best.
Mon May 19, 2014, 12:12 AM
May 2014
Some types of rape are excluded from official reports altogether (the FBI's definition, for example, used to exclude all rapes except forcible rapes of females), because a significant number of rapes go unreported even when they are included as reportable rapes, and also because a significant number of rapes reported to the police do not advance to prosecution.[203] As well as the large number of rapes that go unreported, only 25% of reported rapes result in arrest. Many rape kits are not tested.[204] Only 16% of rapes and sexual assaults are reported to the police (Rape in America: A Report to the Nation. 1992 and United Nations Populations Fund, 2000a).[205][206] Factoring in unreported rapes, about 5% of rapists will ever spend a day in jail.[207]

Contrary to widespread belief, rape outdoors is rare. Over two thirds of all rapes occur in someone's home. 31% occur in the perpetrators' homes, 27% in the victims' homes and 10% in homes shared by the victim and perpetrator. 7% occur at parties, 7% in vehicles, 4% outdoors and 2% in bars.[208] From 2000 to 2005, 59% of rapes were not reported to law enforcement.[209][210] One factor relating to this is the misconception that most rapes are committed by strangers.[209][211] In reality, studies indicate the following varying numbers:

snip

80,000 American children are sexually abused each year. But unreported cases are higher, due to the fear among children.[223]

snip

According to the National Crime Victimization Survey, the adjusted per-capita victimization rate of rape has declined from about 2.4 per 1000 people (age 12 and above) in 1980 to about 0.4 per 1000 people, a decline of about 85%.[226] But other government surveys, such as the Sexual Victimization of College Women study, critique the NCVS on the basis it includes only those acts perceived as crimes by the victim, and report a higher victimization rate.[227] Despite a decline of 60% since 1993, the US still has a relatively high rate of rape when compared to other developed countries.[228]

10. There's no conclusive proof either way, there's basically 2 schools of thought...
Mon May 19, 2014, 12:12 AM
May 2014

1) Porn degrades women and thus contributes to rape culture.

2) Porn reduces rape because people who would otherwise rape can live out those fantasies via porn rather than acting on them.

I think that there's some truth to both of them. Personally I'm fine with porn, but not so much with the porn industry and how the complete objectification of the woman is the standard 95% of the time.

I also think that there'd be a lot more consensus on this topic on DU, if more DUers listened to and read Dan Savage. But most here probably only know him for the definition of Santorum.

Automated Message
AUTOMATED MESSAGE: Results of your Jury Service

Mail Message
On Sun May 18, 2014, 11:38 PM an alert was sent on the following post:

Porn. Rape?
http://www.democraticunderground.com/10024971202

REASON FOR ALERT

This post is disruptive, hurtful, rude, insensitive, over-the-top, or otherwise inappropriate.

ALERTER'S COMMENTS

This is disgustingly dismissive of the horrors of rape. "While this doesn't prove - at all -" And yet the poster tries to use "this" as proof. This post is incredibly insensitive, inappropriate and obviously posted with intent to flame. As a rape survivor, reading this passive aggressive shit day after day at DU is really starting to get old.

You served on a randomly-selected Jury of DU members which reviewed this post. The review was completed at Mon May 19, 2014, 12:08 AM, and the Jury voted 1-6 to LEAVE IT.

Juror #1 voted to LEAVE IT ALONE
Explanation: There is nothing wrong with this post. YOU just don't like it because it's opposite of what you preach. And, this rape survivor says the truth, and asking questions, is okay sometimes. This will probably get hidden though since you had to make it personal with your passive aggressive shit.
Juror #2 voted to LEAVE IT ALONE
Explanation: I have NO problem with this post. I don't mean to make light of the alerter's trigger, but I think the alerter is really overreacting to the post. Manny is not being dismissive of the horrors of rape.

I would suggest that the alerter use the tools we have to hide threads of this sort by keyword.


Juror #3 voted to LEAVE IT ALONE
Explanation: It tests my objectivity to adjudicate a Manny-post but the alerter admits to a somewhat less than objective perspective in the accompanying remarks. I'll have to find in favor of Manny in this particular instance. LEAVE IT
Juror #4 voted to LEAVE IT ALONE
Explanation: No explanation given
Juror #5 voted to HIDE IT
Explanation: Why is this jackass on DU? Enough with his trolling. How about showing third way manny the door? Disgusting post by an unfunny shit stirrer.
Juror #6 voted to LEAVE IT ALONE
Explanation: To the alerter - the data is valid, and the manner of discussing it is dispassionate and entirely reasonable. Such being the case I can't agree to hide it.

On a more personal note - I see no basis in this post, as a stand alone artifact, for the intense reaction you are sharing in your alert. I hope sincerely that you find a way to rebuild your life, and that you avail yourself of every avenue for healing. I truly understand how an earth shattering horror can enter our lives and alter the world as we knew it beyond what we might have believed possible. I also know that time heals if we let it and that the shattered world eventually comes back together in a different but no less normally configured reality.
I found strength by looking for the small good I could do - every day - for those around me. It isn't perfect, but finding my smile in that of another somehow seems a better strategy for finding my center than any other.

You didn't ask for advice, but since I couldn't give you what you did ask for, I hope you'll accept these good wishes in the spirit they are offered.

Juror #7 voted to LEAVE IT ALONE
Explanation: I see nothing " incredibly insensitive, inappropriate (or) obviously posted with intent to flame in this post. If one disagrees with the poster, refute it with objective scientific studies, don't try to ban it.

I see nothing in this post that even addresses the horrors of rape, so I'm not sure how it could be 'dismissive' of those horrors.

If I were to write a post that disputed a link between, say, drone strikes and "24", would I likewise be accused of being dismissive of the horrors of drone strikes when it wasn't even the topic on which I was writing?

Now, that's the ticket, right there! Obesity rates have doubled since 1980!! Fat rapists cannot run as quickly...their victims get away. Or maybe they have a harder time finding their fiddly bits amongst all that avoirdupois! The increase in obesity corresponds with the decrease in rape!

And I'd say that my example "tends to refute the inverse hypothesis" as well--surely present-day successful rapists aren't a bunch of wheezing, unfit, flabby, big-bellied, can't-run chubbies? Hmmmmmm? Why is only YOUR refutation deemed valid or worthy of discussion here, and all others subject to your deliberate dismissal and disdain?

I like math just fine--but speaking of taking whacks at people, you do that plenty, don't you, Manny?

One thing I don't have "limited understanding of" (to use your condescending and blatantly insulting term) is human nature, and I know precisely what your game is. Your schtick is getting old.

Really, for someone so high-handed when it comes to maths, if you were any good at the scientific method, you'd do the work first to prove your theory before you posted your vague musings on a message board that discusses politics.

Surely there's got to be a more productive use of your time than goading people that you know will take the bait on a Democratic board with tangential and certain-to-be-divisive topics, that offer no resolution? You know, there's a new board up and running, but maybe this sort of topic, if you posted it over there, wouldn't produce all the drama and agita it does here. It would probably earn you a heap of quick high fives, a few "not cools," and then sink like a stone.

Now that wouldn't be as much fun, would it?

I really think these "offshoot threads" are rude and unhelpful. They don't seem to be the product of anyone who cares about honest debate--otherwise they'd be associated with the PARENT thread, or at least REFERENCE it.


People who are immature and attention-seeking WANT to leave people saying "What the fuck?" and replying out of context, so they can then jump and play the Cool Kid In The Know, but they really say far more about the person creating them than they realize.

People who want to have conversations with others have them. WITH OTHERS. They don't start separate, portentous threads with flame bait titles.

37. You are claiming correlation equals causation and TBH throwing out flame bait
Mon May 19, 2014, 03:10 AM
May 2014

I'll deal with that second part at the end.
Your claim is more porn = less rape but you all you can produce in support is a heavily disputed graph from a Wikipedia article which doesn't even examine the question at all! Do that in a high school paper and you would rightly receive an "F"

The reduction in rapes as defined by the FBI does seem to be real - see the following article about the reduction in sexual assault as a whole from RAINN but there is at present no explanation for the effect.

In your hypothesis you claim a single cause might be the source of the decline, ignoring the equally valid explanations. There is also a perception of both a greater chance of capture for the rapist together with a similar perception regarding conviction. Another cause might the slight reduction in the percentage of adolescents (particularly males) in society. Personally I think the base for the reduction lies in the ownership of mobile phone, particularly smartphones. It is much easier for the vulnerable to call for assistance, be that a cab, a friend, family or the police. I even (easily) found a graph to support this idea (at this site) - but I don't make any pretense that the effect is real or that I am "just asking"

With that we come to the real offense in your OP, the way you have put this forward. What you have done is concern trolling (Just askin' questions, no offense meant). Instead of actually going out there and looking at research (there has been such research, heavily flawed research but it is still out there) you have thrown out flame bait. Go away do your research and don't ask us to do your work for you.

He is claiming that the lack of a correlation between rape and porn is an arguement AGAINST a causal relationship between rape and porn, which is an entirely valid argument.

Causation does not prove correlation, but a lack of a correlation is evidence AGAINST causation (or a correlation in the opposite direction such as here for the matter).

Rape has been around far longer than porn. Rape does not happen as a result of porn existing or even from watching porn. Rape comes from the evil mind and body that decides to do it. Rape has been around for ages now, literally. Rape is not sex. Porn is sex. Rape is about control. Rape is violence. Sex is not violence, in and of itself. There is a huge difference between sex and rape. Rape is not about sex. It is about control, dominating, hurting, destroying, violence.

Rape has been around far longer than porn.

often won't find "relief" from porn (unless it happens to be be rape porn). I am curious how many guys who commit date rape also watch porn.

For the OP:

As far as statistics sighting that rape has decreased, I don't care about the source, but I don't buy it...it's too easy to "cook the books" so to speak.

How Rape Reports Disappear

When a college woman reports a rape to police, it does not often result in a prosecutor pressing charges. Sexual assault is consistently both an underreported crime and one that rarely leads to an arrest, let alone a conviction. However, it may be hard to track exactly how many rape reports are made to begin with.

One study by Corey Rayburn Yung, an associate law professor at the University of Kansas, concluded nearly 1 in 4 police departments responsible for populations of at least 100,000 persons are undercounting rape reports. The undercounting occurs when officers designate a report "unfounded" after little or no investigation, mark down a report as a lesser crime, or mislabel it as "investigate persons" or another noncriminal matter. Separate research by Kimberly A. Lonsway and Joanne Archambault suggested that sometimes police close a case without investigating and simply describe it as "call to service," meaning that it is omitted from the count.

Even among cases categorized as rape, the Federal Bureau of Investigation's Uniform Crime Report indicates that only a quarter of police reports result in an arrest.

...

"We just see this, unfortunately, in a lot of situations where the police seem very eager to dismiss these cases," said Sandra Park, an attorney with the Women's Rights Project at the American Civil Liberties Union.

http://www.huffingtonpost.com/2014/04/25/college-sexual-assault-police_n_5213384.html


I'm sure this isn't the only article or source for this information, I know I've seen similar stories on DU in the past when it comes to police departments changing crime designations (i.e. cooking the numbers) to make it appear as though violent, or other crimes in general, have gone down when they really haven't.

You can also see how in some municipalities how important solving rape cases are to them by the backlog of rape kits. A certain Alaskan town comes immediately to mind.

47. I would never say the number of rapes has gone down.
Mon May 19, 2014, 08:22 AM
May 2014

because most rapes are not even reported. The few that are reported are not taken seriously. To me, that is the bigger problem, that women who are raped are not taken seriously and given justice.

I doubt very seriously the number of rapes has gone down. If anything, it seems to have remained about the same. Porn really is an entirely different topic than rape. Porn is mostly about sex, except for rape porn, which I am against. Regular run of the mill porn, though, is about sex, not force/control. Rape is about force/control. Rape is violent, but run of the mill sex on video is not. Rape and sex are two different things entirely.

But rape was here before porn and would still be here after it, if it was banned.

In other words, if throughout the period covered by the chart, only a quarter of all rapes are reported, then for each year the actual number of rapes per capita is four times what's shown -- but that would still mean that the per capita rate of rape has tended to decline during this period.

Someone speculated upthread that the rate of nonreporting, far from increasing, has probably declined during this period, because the stigmatization of victims (while still too prevalent) has decreased. If the rate of nonreporting has in fact declined, then the decline in the rate of actual rapes is steeper than what the chart suggests.

You write, "I doubt very seriously the number of rapes has gone down. If anything, it seems to have remained about the same." If you start with the premise that the number of rapes has remained the same, then your explanation for the chart is that the rate of nonreporting has increased. That's why I asked if there's any independent evidence for that assertion. Otherwise the whole argument is circular.

On what basis do you state that the number of rapes seems to have remained about the same? The chart shows per capita rates, not total number, so the number would stay the same if population were increasing quickly enough, but my guess is that it's not. In any event, the per-capita rate in the chart in the OP seems to be the most logical measure to use.

 I am curious how many guys who commit date rape also watch porn.

I once heard that a poll of men asking if they look at porn resulted in around 50% saying that they do. Another poll shows 50% of men lie on polls. Bottom line, little or no correlation.

50. I believe the biggest single factor

In the reduction of rape stats are the use of modern forensics as an investigative tool. I would be interested in stats analyzing the number of rapes committed by rape convicts and the average prison sentence for convicts. Most rapists have multiple victims, if they are apprehended quicker and imprisoned longer, the incidence would be lower.

If rape kits would be investigated rather than allowed to sit on shelves for years on end, and if rapists would be charged and convicted and given reasonable sentences, I agree it would make a difference.

Investigate rape kits that should be remedied. I also suspect that the investigation of rape is a higher priority now than in the 60s or 70s, even if it isn't what it should be now.

55. I have no idea whether porn causes rape, but this doesn't prove or disprove anything.
Mon May 19, 2014, 08:48 AM

You're right that it doesn't prove that more porn equals less rape. It also doesn't disprove that more porn equals more rape. In order to do that, you'd have to have another chart with the amount of rape there would have been without porn, so you can compare them. And that other chart doesn't exist.

The fact that rape is down while porn is up is an interesting observation, that's pretty much it.

I don't know whether porn increases, decreases, or has no effect at all on the number of rapes.

But the chart is essentially meaningless. There are too many other variables, and no way of knowing what the number of rapes would have been with everything else other than porn held constant.

For example , one could start eating more and still lose weight ... If one also starts to exercise more to deal with increased calories.

So we have to carefully consider ALL factors.

It is like the gunners conclusion that moe guns leads to less crime because more guns are being sold and crime in some areas in on the decline.

When all, or even most, women make the same as men and have wealth in proportion to their numbers, then and only then can anyone convince me that women engage in porn of their own volition.

I'm not a porn expert, but I've read up on it, see it and have had enough acquaintance with porn watchers to weigh in.

Mon May 19, 2014, 12:12 PM

work here. It's not just rapes that have plummeted according to stats.

I don't trust violent crime stats over the last 20 years. In NYC pressure came from the mayors office on down to bring down the number of violent crime reported. Officers were encouraged to dissuade people from filing reports or to file them into a lower category. Their performance was rated on this, at precinct and individual level, the pressure was intense to show an improvement in the "quality of life" in NYC. The officers I knew back then were disgusted and are now retired, and I think the city pretty much denied the whole thing even though I heard many talk about it openly. I wonder how much this has impacted the stats vs birth rates because I had seen reports of the same thing happening in other cities.

And rape stats are even worse, jeeze. I meant the unreported stats are used not when she doesn't report it, but when LEO declines to file a report, I think. I think it is very difficult to get reliable samples on truly unreported rape. And it is hard to find studies that are sampling using the same categories for direct comparison. It's hard to say how much they reflect reality.

That said, I don't think porn causes anyone to be a rapist, I think if they are already on that road they may find materials that stoke their interest. But I think plenty of those kinds of materials can be found in the news, popular films and true crime reporting too. Our culture is saturated with violence, and often seems to celebrate it. I am not sure how they would prove any potential rapes were prevented by the availability of porn. The porn users themselves would be unaware they were diverted.

"While this doesn't prove - at all - that more porn equals less rape, it does seem to counter any claim that more porn causes more rape. "

The last section of your comment needs to be changed in order to make it accurate. As it stands, your statement is false.

It's statistics. What I said is about all that can be said from the data at hand.

The most accurate thing to say is that the effect of porn on rape is either quite small compared to other factors, or there's no effect, or porn actually decreases rape by somewhere between a little and a lot.

143. The problem is that the OP's phrase "seem to counter" is annoyingly vague.
Mon May 19, 2014, 02:54 PM

Some of the responses in this thread would be appropriate if the OP had said "conclusively refutes" instead of "does seem to counter" -- but that's not a reasonable interpretation of the vague phrase.

As a lawyer, I tend to look at these things from the perspective of a trial. Suppose, somehow, one issue in a trial was whether increased availability of porn causes an increase in the incidence of reported rapes. When you have a fact (e.g., incidence of reported rapes is down 80% from 1973 to 2003, during which time porn became more available) and a proposition (e.g., increased availability of porn does not cause an increase in the incidence of reported rapes), here are some standards that are not the legal standard for admissibility of evidence:

1. The fact conclusively establishes the proposition.
2. The fact establishes the proposition beyond a reasonable doubt.
3. The fact makes it more likely than not that the proposition is true.

Here's the actual legal standard of relevance:

4. The fact makes the truth of the proposition more likely than it would be without the fact.

At this hypothetical trial, the chart in the OP would be admissible. (More precisely, an objection of irrelevance would be overruled. I'm not considering whether there are other objections that might be sustained.) Also admissible would be countervailing facts such as the influence of demographics on incidence of major crimes, the decline in other major crimes, the increasing tendency of police departments to distort the statistics to make themselves look good, etc.

If one takes "does seem to counter" in this sense -- treating it as just one piece of evidence -- then the statement is true.

It's like showing paternity through DNA testing. One can't prove or disprove paternity this way, but one can show that it's pretty likely or unlikely.

That's the way it is in statistics.

The OP phrasing has apparently been interpreted, by different people, as meaning different ones of the four standards that I enumerated in my post. My point was that the fourth is the most sensible interpretation and that, on that interpretation, the statement in the OP is true.

Much of the seemingly disputed statistical analysis in this thread seems to me to arise from different understandings of what thesis was being advanced on the basis of the statistics, rather than from different understandings about whether the statistics support that thesis.

I'm fine with the concept of legalising prostitution, because it's no business of mine if someone voluntarily chooses to rent their body out. But without rules, it opens teh door to massive abuses. At the very least, you'd need age regulation and STD checks.

Legalizing it removes the fear, stigma and puts an end to these stupid police "vice" programs.

Obviously prostitution should only be legalized for those over age 18 but I disagree with government forcing mandatory STD checks, if people want to do business with a prostitutes who don't want to disclose their STD status then so be it. Eventually people will do business with prostitutes who practice safe sex and disclose their status while the others who abuse drugs such as meth, heroin and crack will be put out of business.

Also, it neglects that rape (or rather, the rapist's decision to rape) is affected by many factors, some of which we probably don't know exist.
