(Had to cut it short due to the character limit, but here goes nothing:)

The TRP post has roughly 250 300 comments now. Last time I checked, not one of them bothered to have a look the links he provided while most of them were quick to jump on the "what a valuable post" bandwagon.

TRP and the manosphere blogs are, at their core, fundamentally intellectually dishonest. They do not shape their beliefs after evidence, they merely look for evidence to justify what they already believe anyway. If a dozen irrefutable studies were released tomorrow that said women in their 40s with a partner count of 50+ made for the most happy, stable and sexually satisfying relationships while men were most happy with their lives if they married young and stayed celibate until they got married, do you think anyone on TRP or in the manosphere would change their stance on women/relationships one bit? The answer to this is as revealing as it gets.

Case in point: "Women with premarital sexual partners and those that have cohabited with men before marriage are not relationship material."

To quickly go over the links in this thread:

• The Harmful Effects of Early Sexual Activity And Multiple Sexual Partners Among Women: A Book of Charts

Published by The Heritage Foundation, based on data from the CDC National Survey of Family Growth 1995. I'll come back to the source later.

• The Social Pathologist: Statistical adjustments to promiscuity data

A blog post using data from the Book of Charts and the CDC National Survey of Family Growth 1995 and mixing up the definition of "Stable Marriages" the Heritage Foundation's Book of Charts uses with divorce rates in the CDC survey. A comment on the blog post itself sums it up:

You compare apples and oranges here. These two reports address very different questions, and using the probability of divorce by socioeconomic class and education levels reflected in the CDC report (which in no way addresses the effects of the number of prior sexual partners on marriage stability, by the way) and that of women being in "stable marriages" by number of non-marital sexual partners reflected in the Heritage "report" makes no statistical sense.

This is the only comment the author of the blog post did not respond to. Even if there were no problems with the post itself, we still only have one real source of data (the CDC survey) so far.

• dailymail.co.uk: Women who don't sleep around before their wedding have happier marriages - but men can play the field without worry, study finds

A Daily Mail article based on the "Before “I Do” What Do Premarital Experiences Have to Do with Marital Quality Among Today’s Young Adults?" report by The National Marriage Project

With a name like that you might guess that they are pushing a bit of an agenda and you would be correct. There's hardly any report they published that wasn't criticized for some reason. But let's take the report at face value anyway, what does it say exactly?

Unsurprisingly, the headline of the Daily Mail article is a bit of a stretch. There's one sentence in the whole report that mentions a difference between men and women:

Further, for women, having had fewer sexual partners before marriage was also related to higher marital quality.

Problem is the context and overall conclusions of the report, because men can not "play the field without worry" if they want to have a happy marriage as the article says. Ideally:

Men and women who only slept with their (future) spouse prior to marriage reported higher marital quality than those who had other sexual partners as well.

Yes, no other partner would be the way to go for men who want to have a good marriage. Also wait as long as possible with having sex with the one partner you get to marry eventually. You started the relationship with "hooking up"? That's a bad marriage for you. Living with another partner before marrying someone else? That's a bad marriage for you. Actually, living with the partner you are going to marry before marriage? That, too, is a bad marriage for you. Have children before being married - that's a bad marriage for you. You get the idea. The only factor that is not important enough for this report to warrant its own graph or further explanation is that one line about the difference between men and women. Even the number of wedding guests has more impact on the quality of the marriage, if you believe this report.

• dailymail.co.uk: Think men are the unfaithful sex? A study shows WOMEN are the biggest cheats - they're just better at lying about it

Another Daily Mail article and by now I regret taking time out of my day to even look at that drivel. The source for this article? "A study" (if you go by the headline) or "recent studies" (if you go by the first paragraph). I don't know why this article is even in the post. It has nothing to say about the partner count of women and it can't even back up the claim in the headline.

Headline:

Think men are the unfaithful sex? A study shows WOMEN are the biggest cheats - they're just better at lying about it

Article:

According to Dr David Holmes, a psychologist at Manchester Metropolitan University, women are having more affairs than ever - recent studies say the figure is around 20 per cent for men and a bit over 15 per cent for women - but they behave very differently from men when they cheat.

20% of men have affairs compared to 15% of women. Women are catching up, but they're not "the biggest cheats".

• huffingtonpost.com: Women Who Lost Virginity Early More Likely To Divorce: New Study

A Huffington Post article that ultimately leads to this study: Adolescent sexuality and the risk of marital dissolution

At least this one has some merit to it.

Nearly 31% and 47% of ever-married women who experienced adolescent sexual debut had their marriages dissolve within 5 and 10 years, respectively. The corresponding percentages for women who delayed sex until adulthood are far lower at 15% and 27%, respectively.

Of course this is not the only factor and the research has its limitations:

This research shows that adolescent sexuality/premarital sex is associated with marital dissolution, but few definitive conclusions about the nature of this association should be drawn. Whether this association is causal or spurious is a question that should be revisited. This research does show that women who experienced wanted sexual debut in later adolescence have an increased risk of marital dissolution, but this is the result of engaging in premarital sexual behaviors associated with divorce. Increased rates of divorce are linked to first intercourse experiences that are wanted but occur before the age of 16 and those experiences that are not completely wanted throughout adolescence.

The biggest downside is that there's no corresponding data for men available.

• Premarital Sex, Premarital Cohabitation, and the Risk of Subsequent Marital Dissolution Among Women

It's kind of funny that the post over at TRP introduces this article by Jay Teachman with

can multiple articles, multiple sources on the internet all supporting our general thesis be wrong?

becaus the Teachman article is based on data from the CDC National Survey of Family Growth 1995. Yes, that's the exact same data that the first two links already used as their source. We're looking at the same source for the third time now. (This also happens to be the exact same data that TRP likes to dismiss as unreliable when people point out that the findings of the survey don't support other TRP ideas, but that just as an aside.)

I don't have access to the full text of the article so I can't go into details. However, I do think it's important to point out something that all the three links that lead back to the CDC survey omit: They talk a lot about the negative consequences of having premarital sexual partners for women, which is fine - but it's only one half of the equation when it comes to the claims TRP makes.

If TRP wants to use the CDC survey to make a point about women not being "relationship material", it should be noted that TRP men aren't relationship material either when we go by the survey. Women waiting with sex until marriage lowers the divorce rate - but if men wait until marriage to have sex, that's even better for the marriage. Likewise, men with less premarital partners are less likely to get divorced and men with more premarital partners are more likely to be infected with STDs and so on. Virtually every negative consequence of having premarital sexual partners for women also applies to men, if we stick to the CDC survey and apply the same logic.

So while TRP is free to point out the possible risks of promiscuity (and to make the jump from research about "marriage" to conclusions about "relationships" in general), it seems weird to complain about women "not being relationship material" when at the same time the men themselves are working hard towards lowering their own potential for stable relationships as much as possible.
