So why do people do the sexual things they do?
And more to the point: If you have a theory about why people do the sexual things they do, how would you prove it?
The data everyone’s talking about, though, isn’t so much about what kinds of dirty pictures women and men like to look at. (Although that is interesting and pertinent: if the research is correct, men tend to be aroused by a fairly narrow band of imagery that clearly correlates with their sexual orientation, while women tend to be aroused by imagery that’s all over the map.) What’s getting the attention is the stuff about how hard it is determine which images women are aroused by… because women’s self- reported mental responses, and their involuntary genital responses, don’t match up.
At all.
Hm.
Now. Chivers’ conclusion is that women are physically aroused by a broader range of visual stimuli because, due to evolutionary pressure, it behooves women to be physically ready for sex they don’t want. To put it more bluntly: Women get raped. If women are physically aroused by a broad range of visual stimuli, we will be physically ready for sex even if we don’t want it, and are thus less likely to be injured during rape. Thus increasing our chances of survival.
Um…
Okay. That’s the preface. Here’s what I want to talk about.
So here’s my argument.
Is Chivers’ explanation plausible?
Sure.
And I’ve spent the last twenty minutes or so coming up with a whole passel of explanations that are also plausible.
It could be that women’s sexuality is more bound up with emotional attachment than men’s… and emotional attachment is more complex than simple lust, with a wider range of potential objects.
It could be that women live in a culture steeped in imagery of sexual women, a culture where women are constantly presented as objects of sexual desire, and thus even straight women learn to see other women that way.
It could be that women’s sexual desire is less gender- specific than men’s. (There’s some other data in the Times article backing up this theory.)
It could be that women are less aroused by visual erotic stimulation than other forms (such as verbal), and that showing women visual images isn’t the best way to figure out what we’re aroused by.
And it could be that women’s sexual desire is more complex and multi-factorial than men’s in many ways, with a less specific and more sweeping scope.
It could be that women are taught from birth to be disconnected from our bodies and our sexuality, so we don’t find it as easy to identify our genital sexual responses.
It could be that women are taught from birth that being sexual is dirty and bad, and so aren’t as comfortable speaking frankly about it as men. In other words, women don’t want to admit what it is that’s turning them on. (Even to themselves. See above.)
It could be that male physical arousal is easier to notice — what with the boner and all — and thus men are more likely to define “arousal” as “genital arousal,” and to self- report it as such.
It could be because of Chivers’ “surviving rape” explanation.
And it could be, again, that women’s sexuality is more complex and multi-factorial than men’s, with a stronger “purely mental” component.
To be very clear: I’m not actually advocating any of these positions. I’m coming up with them to make a point. That point:
I could do this all day.
And I’m not sure how you would test any of these theories.
And as any good skeptic knows: If a theory isn’t testable or falsifiable, it’s worthless. Whether it’s a belief in God, or a conspiracy theory, or a simple theory about the evolutionary forces driving the development of certain sexual responses… if there’s no possible data that could prove your theory incorrect, or no way to acquire further data either supporting or contradicting your theory, then your theory is useless. It has no power to explain the past or predict the future. It’s pointless. It’s not even wrong.
It’s a lot harder to come up with theories that are really supported by all the evidence; theories that explain and predict evidence that can’t be explained or predicted any other way; theories that are more than just examples of the human brain’s amazing ability to come up with explanations for stuff.
By all means, we need to be doing careful scientific research into human sexuality. I wouldn’t in a million years suggest otherwise. We just need to be very cautious, very rigorous, and very slow, about coming to conclusions about what that research means.
These ideas were developed in a comment thread on Pharyngula.
Greta, others, Scientific American recently publishing a really nice piece on the problems with the evolutionary psych approach. These criticisms were far more detailed than the more common Just So Story, and I think all the more damning as a result.

I am personally asexual so I do not care about sex or relationships :D. But good article anyway.
Thanks for linking to Wikipedia’s “Just-So Story” entry. I’ve had the same exact feeling about many, many evolutionary explanations and arguments that I’ve heard before, as well as many from other spheres, and it’s greatly alleviating to hear there’s an actual term for this practice. It’s kind of annoying when even bright minds act out of haste.
And the disparity between genital and mental reports of sexual arousal doesn’t surprise me in the least. As a guy, I know I’ve gotten erections just out of the blue, in the absence of any plausible stimuli, and I can even retain them awhile without experiencing excitement, so it’s pretty obvious there’s more than one level in the process. I think there’s something akin to the “Don’t think about X – induces thought about X” paradox involved as well.
A little while back, I wondered how psychologically felt arousal could lead to physiological effects that can’t be voluntarily controlled. I can’t just give myself a boner or take it away by simple whim, like I can wave my hand. So I concluded that your subconscious – if that’s what we want to call it – might have some degree of monitoring of higher-level conscious thought. When you think “X is sexy”, the lower levels of your mind will notice and the appropriate actions will take effect.
But what if you think, “X is sexy to some people,” or “I’m supposed to think X is sexy,” or even “I’m not supposed to think X is sexy.” Some thoughts involving sexuality could be misinterpreted by your mind and lead to the disparate genital and mental responses! That was my first theory.
I think the reason women’s feedback on arousal doesn’t match up to physiological data is because women are so repressed in our society.
Whenever I ask a guy what his fetish is, he can tell me right away. But lots of women say they don’t have one. YES THEY DO! Everyone does! They don’t even acknowledge their own fantasies, they bury them.
A brain isn’t a landfill, it’s a garden. Take care of your garden and enjoy all the pretty flowers and juicy fruit!
Beautifully expressed. When I read that article awhile ago, I had to scratch my chin as well. But… well… it was a NYT article, and given that science journalism isn’t always great, and it really isn’t my area of study, I wasn’t sure how to critique the positions posited. I enjoyed this read, though. /blogbookmarked
I have always been annoyed with these evolutionary arguments for observed differences in male and female behaviors. One of the aspects of it that makes little sense to me is that if a male has a trait that is beneficial to him only as a male, and he lives long enough to pass on his genetic code as a result, his offspring might just as easily be a female who inherits the trait as a male. The female who has a trait that aids her in reproduction might pass that predisposition on to her sons. As we all know, the fashion model who mates with a funny looking genius is just as likely to produce odd looking people with the model’s intelligence as stunningly beautiful geniuses.
“A scientific study where random men approached girls on college campuses and said, ‘Will you have sex with me right now?’âto which most of the ladies said ‘no thanks,’ surprisingly. But three-quarters of men said yes to the same question!”
Wait! A random group of men asking for sex were refused by most women? However, when this same random group asked other men the same question, 3/4 of these men said yes to having sex with them?
