Is the IFS Study Saying Christians Have Better Sex WRONG?

Asking the question if the IFS study claiming Christians have better sex wrong

The Institute for Family Studies, a conservative think talk, just published an article claiming that religious people have better and more frequent sex.

They published an article in the Atlantic explaining their findings, and a larger 62-page report on their website.

They were commissioned to do this by a Catholic group, and they do report their findings in terms of religious people overall, and then break it down by Catholic and Protestant specifically later.

Apparently on right wing social media, people are using this article to call our Bare Marriage findings into question.

In our survey of 20,000 women for our book The Great Sex Rescue, we found that women who internalized toxic teachings about sex (the obligation sex message; that all men struggle with lust; that wives should have sex to keep their husbands from watching porn, etc.) have worse sex lives than people who don’t believe these things.

A follow-up survey of thousands of men for our book The Good Guy’s Guide to Great Sex found the same toxic teachings hurt men too. And our matched pair survey for The Marriage You Want confirmed our findings.

I’ll also point out that the IFS section of the study looking specifically at faith was based on a survey of 3,125 married individuals, including 1,243 Protestants. This is far smaller even than our smallest surveys.

But here’s the thing: Our message all along has been consistent, and quite in line with this IFS study:

Religious people tend to have better sex and better marriage than non-religious people.

Absolutely! We agree. And this has been found by countless other studies too. It’s one of those things that is widely known in the literature, and it’s expressed in scientific terms like this: religiosity is a protective factor.

So I’m not surprised by these findings at all.

But…just because religious people do well as a group does not tell us how the subgroups do.

And this is where the rubber hits the road, and this is what we were trying to tease out in our studies:

Yes, religious people do well as a whole. But what happens to the subgroup of religious people that believe toxic messages? What happens to the subgroup that act out male hierarchy in marriage?

Then we see a whole different picture.

I’m going to explain what’s wrong with how people are looking at this study in this article, which also appeared last Friday on my Substack.

But if you’d rather watch/listen, Keith and I sum up this article in last week’s Friday Round-Up here:

Let’s jump in to the nitty gritty of dissecting this study!

The problem with saying, “Religious people do better,” is that if you’re religious, you’re inclined to say, “Well, I’m religious, so I must be doing better!” But in a large group, you may actually be bringing the average down, not up.

Imagine a classroom of 30 kids. 25 of those kids have super involved parents. Their parents pay money for tutors. They read to their kids for two hours a day. Kids have limited screen time. They go to museums on summer break.

Five of those kids, though, spend their lives on screens, and don’t talk to their parents much.

That classroom may have the highest standardized scores in the district. But just because that classroom does better as a whole does not mean that those five students can claim, “see, we’re the smartest kids in the district!” They just happened to be lumped in with the really smart ones, and they’re coasting on the reputation of those other kids—a reputation that they didn’t earn, and that they even worked against.

So let’s break it down:

Religious people = anyone who believes in any religion and attends a religious service on a regular basis

Christians = Catholics, mainline Protestants, Pentecostals, fundamentalists, evangelicals, Reformed Christians, and Orthodox (and Mormon, depending on the classification)

Protestants = Mainline Protestants, Pentecostals, fundamentalists, evangelicals, Reformed Christians.

Evangelicals = Egalitarians and Complementarians.

Complementarians = those who believe in male headship and act out male hierarchy and those who believe in male hierarchy but do not act out male hierarchy, and make decisions together (this latter group is much bigger than the first group)

Here’s what I mean in graphic form. When you follow this all the way down, you can see what a small subset “complementarian evangelicals” are of Christians in general, let alone religious people in general.

A chart showing how complementarians who believe and act out headship are only a small subset of Christians as a whole.

To claim that because “religious people do better”, or even “Christians do better”, or even “Protestants do better” than secular people does not mean that you can claim that “evangelicals who believe in male headship and who act it out do better”. And the latter is what we’ve measured definitively.

Most studies measuring whether Christians do better than the general population do not compare subgroups of Christians. Our study did, and that’s what makes our study different.

I can completely believe and agree that Christians as a whole do better than the general population, because this is what we have loudly said for years, and what our stats have showed too.

But this doesn’t mean that those who have internalized toxic messages, and who act out hierarchy in their relationships, do better. To know that, you’d have to measure that specifically. And we did. They don’t do better at all.

Okay, that’s where I agree with the overall message of the IFS study. Now I’d like to note some areas where I have some concerns.

Having more frequent sex is not necessarily something to brag about.

This study was framed in social media and in the Atlantic as “Christians avoided the sex recession.” So Christians were having more sex, and this was seen as a good thing.

And, in general, marital satisfaction does travel with sexual frequency. More sex tends to mean higher marital satisfaction.

But if you drill down (which we have), you find that this only applies in certain cases. For some couples, more sex makes marriage worse. 

The only thing frequency of sex tells you is whether or not the man was reaching orgasm.

That’s it. Men pretty much always orgasm during sex, but other than that, nothing is guaranteed.

She may not be reaching orgasm (evangelicals have a 47 point orgasm gap, where 95% of men report orgasming almost always or always compared with just 48% of women).

She may be feeling distant or not emotionally connected during sex. She may even feel used (as 18% of our respondents reported). And if she’s feeling used after sex, her marital satisfaction would improve by NOT having sex.

When we look at the group of women who don’t reach orgasm and don’t feel emotionally connected, their marital satisfaction doesn’t improve by having more sex.

Frequency is not the point; the quality of sex and the marriage is the point.

 

 

Beware the Rose Coloured Glasses phenomenon!

The IFS has actually warned about this before in their own studies. In their World Map 2019, they said:

It is possible that simply being married is more important to highly religious women, which may raise their satisfaction ratings. They may be more likely to look at their relationship through a rose-colored lens.

Institute for Family Studies

World Map 2019

In other words, many religious women have been told that marriage is the point and pinnacle of life, and so marriage is a larger part of their identity than it is for non-religious women. If you ask women, then, “how satisfied are you with your marriage?”, they may be more likely to report that they are highly satisfied.

In this most recent IFS study, they said they measured marital quality by simply asking how happy they were with their marriage. But they didn’t say if they drilled down any further, and I can’t find any evidence that they did (so even though they’re aware of the rose-coloured glasses problem, they’re not trying to tease it out).

In the Marriage You Want, we used FOUR different previously validated question sets to measure marital satisfaction—the Trust in Close Relationships Scale; the Kansas City Marital Conflict Scale; the Relationship Flourishing Scale; and the Couple’s Satisfaction Index. Together these were dozens of questions measuring all kinds of aspects of marriage, including things like:

  • I feel as if I can share my weaknesses with my spouse

  • My spouse understands my point of view when we’re in arguments

  • I have shared hobbies with my spouse

  • My spouse initiates repair when there is a rift in our relationship

Etc. etc. etc. In other words, we didn’t just ask, “are you happy?” We asked a whole bunch of questions that researchers have already found are correlated with marital satisfaction.

We’ve actually found some evidence for the rose-coloured glasses phenomenon in our dataset. We’ve described this in a previous article for Baptist News when we were critiquing Nancy Pearcey’s claim that complementarian men make the best husbands. Here’s what we said:

We contrasted those who strongly agreed that marriage should not have a hierarchy (egalitarian) and those who strongly disagreed (complementarian). Complementarian beliefs were correlated with 33% higher odds of having above average global marital satisfaction but also correlated with 35% higher odds of having below average specific marital satisfaction. While complementarian women were more likely to rate their overall satisfaction highly, when you asked them about individual markers of satisfaction, things didn’t look as rosy.

Those rose-colored glasses are present in the bedroom, too. When we look only at women who never reach orgasm, for instance, they are 22% more likely to say they’re satisfied with their orgasm frequency if they also believe in hierarchy in marriage compared with women who believe marriage should be equal.

Baptist News, Do Complementarian Men Do Better? A Response to Nancy Pearcey

Basically, complementarian women are MORE likely to say, “Yes, I’m happy,” when asked broad questions, but when asked about specifics, they’re actually LESS likely to be happy than those who don’t act out complementarianism.

We need more concrete measures of sexual satisfaction.

There are studies that show that women judge their sexual satisfaction on what the man is experiencing. If he is happy, then their sex life is happy, because the sex life is not about what she feels, but about something that he needs. So if she’s doing her duty and he’s happy, then their sex life is good.

One study summed up the findings this way:

Several qualitative studies found that in women’s definitions of sexual pleasure, having an orgasm played a minor role as compared to other themes like emotional intimacy or partner satisfaction.

Marie-Feline Dienberg et al.

Current Sexual Health Reports, Women’s Orgasm and Its Relationship with Sexual Satisfaction and Well-being

So she’s more likely to judge her own sexual satisfaction on her partner’s satisfaction. And this would be even more true in subgroups that have stressed men’s desperate “need” for sex while downplaying women’s sexuality completely (again, Emerson Eggerichs, in his chapter on sex, never once mentioned that women can feel pleasure too, and made the fact that sex takes such a short amount of time a bonus for women).

To truly judge sexual satisfaction, we need to know orgasm rates; how emotionally connected she felt during sex; and how emotionally connected she felt after sex. We also need to know if coercion was present, and if sexual pain was present.

From the IFS report, though, these are the only two questions that were asked:

  • “About how often did you have sex during the past 12 months?”

  • “How would you rate your overall sex life these days?”

That doesn’t give us a complete picture.

“Owning the Libs” is not necessarily something to brag about

Finally, just because religious groups do better than secular groups doesn’t mean that we should pat ourselves on the back.

Think about the benefits from religiosity. Being involved in a faith community means you’re less isolated. You have ready-made friends. You have people who will jump in if you’re in the hospital; if you have a baby; if someone you love dies or is sick. You have people who can baby-sit. You have ready made events for your kids. You have a network of people to help you find a job or mentor you.

Religious people have a leg up!

But also, think about the kinds of people who are able to attend church services several times a month. Unless you live in a city with good transportation, it means you have to have a car. You can’t have super chaotic work schedules. So you’re likely in a higher socioeconomic group.

You’re less likely to have major addiction issues or mental health issues or chronic health issues, since those keep people from church.

And those are the benefits without even considering the impact of having a relationship with God; with having a purpose for your life; with having a ready-made way to feel peace.

So of course religious people should be doing better! The question is not do religious people do better; it’s how much better do religious people do.

A fourth grader bragging about beating a first grader in a race would be silly. Of course they should win! They’re bigger. The real issue is how much did they win by? Here is the IFS chart:

Again, this is pretty in line with what we also found. But is this something to brag about?

Rather than owning the libs, we need to ask what actually brings health and wholeness.

Let’s stop bragging about doing better than secular couples, and start looking at whether the things that we’re teaching about sex actually lead to flourishing or not.

Yes, of course religious people do better! But if we’re simultaneously teaching things that make things worse, than rather than bragging about doing better, we’re missing out on the flourishing God has for us.

By continuing to brag about how much better we’re doing, instead of confronting the fact that we should be doing even better, we’re missing the point entirely.

What do you think of the study? What’s your initial reaction? Let’s talk in the comments!

Do Women Care about Men’s Appearance?

Are women visually oriented? What we usually hear in the church is that God made men to be visual (the Every Man's Battle authors say that God made men to receive sexual gratification through the eyes). Women, on the other hand, just aren't. We aren't visual at all....

    I can not help but find the “owning the lins” aspect of this weird. I say that because I am sitting here going ok what exactly are you trying to prove?

    If you want to show that marriage is good for society there are plenty of case studies on that. Nit just individual studies but studies of studies.

    If they are trying to be like see the stereotype isnt true that church goers cant enjoy sex well i just sit here going your research said the same thing.

    It also said though that hey demanding wives hive sex directly can lead to vaginismus.

    That saying all men are feral animals who need women to effectively sedate them using sex is not only horrific for women but it treats men like they are subhuman.

    I find it baffling. If they are wanting to see if you will show that hedonism is a bad idea well again you can just look at the testimonies of folks who leave poen or folks who can be like I lived that way here is why I stopped.

    I find more and more I sit here going I can walk and chew gum. I can be like Sheila is mathematically correct about her research while also going I can disagree about immigration or whatever and so so respectfully.

    And if anything I find myself just going if not for these people I would still be believing Every Man’s Battle.

    So thank you Sheila and Joanna and all.
