Sexual Selection: Hunkier Than Thou
The Economist ^ | December 9, 2010 | The Economist

Posted on 12/09/2010 5:26:05 PM PST by Tolerance Sucks Rocks

WHEN it comes to partners, men often find women’s taste fickle and unfathomable. But ladies may not be entirely to blame. A growing body of research suggests that their preference for certain types of male physiognomy may be swayed by things beyond their conscious control—like prevalence of disease or crime—and in predictable ways.

Masculine features—a big jaw, say, or a prominent brow—tend to reflect physical and behavioural traits, such as strength and aggression. They are also closely linked to physiological ones, like virility and a sturdy immune system.

The obverse of these desirable characteristics looks less appealing. Aggression is fine when directed at external threats, less so when it spills over onto the hearth. Sexual prowess ensures plenty of progeny, but it often goes hand in hand with promiscuity and a tendency to shirk parental duties or leave the mother altogether.

So, whenever a woman has to choose a mate, she must decide whether to place a premium on the hunk’s choicer genes or the wimp’s love and care. Lisa DeBruine, of the University of Aberdeen, believes that today’s women still face this dilemma and that their choices are affected by unconscious factors.

In a paper published earlier this year Dr DeBruine found that women in countries with poor health statistics preferred men with masculine features more than those who lived in healthier societies. Where disease is rife, this seemed to imply, giving birth to healthy offspring trumps having a man stick around long enough to help care for it. In more salubrious climes, therefore, wimps are in with a chance.

Now, though, researchers led by Robert Brooks, of the University of New South Wales, have taken another look at Dr DeBruine’s data and arrived at a different conclusion. They present their findings in the Proceedings of the Royal Society. Dr Brooks suggests that it is not health-related factors, but rather competition and violence among men that best explain a woman’s penchant for manliness. The more rough-and-tumble the environment, the researcher’s argument goes, the more women prefer masculine men, because they are better than the softer types at providing for mothers and their offspring.

An unhealthy relationship

Since violent competition for resources is more pronounced in unequal societies, Dr Brooks predicted that women would value masculinity more highly in countries with a higher Gini coefficient, which is a measure of income inequality. And indeed, he found that this was better than a country’s health statistics at predicting the relative attractiveness of hunky faces.

The rub is that unequal countries also tend to be less healthy. So, in order to disentangle cause from effect, Dr Brooks compared Dr DeBruine’s health index with a measure of violence in a country: its murder rate. Again, he found that his chosen indicator predicts preference for facial masculinity more accurately than the health figures do (though less well than the Gini).

However, in a rejoinder published in the same issue of the Proceedings, Dr DeBruine and her colleagues point to a flaw in Dr Brooks’s analysis: his failure to take into account a society’s overall wealth. When she performed the statistical tests again, this time controlling for GNP, it turned out that the murder rate’s predictive power disappears, whereas that of the health indicators persists. In other words, the prevalence of violent crime seems to predict mating preferences only in so far as it reflects a country’s relative penury.

The statistical tussle shows the difficulty of drawing firm conclusions from correlations alone. Dr DeBruine and Dr Brooks admit as much, and agree the dispute will not be settled until the factors that shape mating preferences are tested directly.

Another recent study by Dr DeBruine and others has tried to do just that. Its results lend further credence to the health hypothesis. This time, the researchers asked 124 women and 117 men to rate 15 pairs of male faces and 15 pairs of female ones for attractiveness. Each pair of images depicted the same set of features tweaked to make one appear ever so slightly manlier than the other (if the face was male) or more feminine (if it was female). Some were also made almost imperceptibly lopsided. Symmetry, too, indicates a mate’s quality because in harsh environments robust genes are needed to ensure even bodily development.

Next, the participants were shown another set of images, depicting objects that elicit varying degrees of disgust, such as a white cloth either stained with what looked like a bodily fluid, or a less revolting blue dye. Disgust is widely assumed to be another adaptation, one that warns humans to stay well away from places where germs and other pathogens may be lurking. So, according to Dr DeBruine’s hypothesis, people shown the more disgusting pictures ought to respond with an increased preference for masculine lads and feminine lasses, and for the more symmetrical countenances.

That is precisely what happened when they were asked to rate the same set of faces one more time. But it only worked with the opposite sex; the revolting images failed to alter what either men or women found attractive about their own sex. This means sexual selection, not other evolutionary mechanisms, is probably at work.

More research is needed to confirm these observations and to see whether other factors, like witnessing violence, bear on human physiognomic proclivities. For now, though, the majority of males who do not resemble Brad Pitt may at least take comfort that this matters less if their surroundings remain spotless.

Well, to defend women, it goes both ways I would think...

I don't agree. I rarely see a 9/10 woman going home from a bar with the 2/10 guy. It just does not happen.

I really do not know how the poofs over at The Economist have ANY idea what attracts women.

When I'm out riding the Norton, my butt sticks up in the air (clubman bars) so I stuff my wallet with leaves, twigs, newspaper clippings...so that it looks extra fat and bulgy in my rear pocket.

The ladies will fall in line and follow you around like a herd of cats following somebody waving around a hotdog dipped in tuna.

Hmmm...perhaps that's not a good analogy.

“More research is needed...”

Have you ever noticed how this phrase, or something akin to it, always appears in a description of a scientific study?

My wife and I were talking about this recently. Women like “bad boys” then they cry and whine when the “bad boy” abuses her. Uh, what did they think he was going to do?

Guys let me break it down for you simple:

One of my favorite set of self-explanatory photos. Thanks for posting them again.

For me, I like looking at handsome men, just as I like looking at handsome horses. They’re rather hypnotizing in their beauty. That doesn’t mean I’m necessarily attracted to them. The men I’ve always preferred have been the Reagan/Bush tough guy type. They don’t have to be handsome—they can even be kind of ugly—just have to look (and be) tough and competent in the world with guy stuff, like guns, trucks, power tools, etc.

A 2/10 guy does that and she will say "get away from me you creep" and maybe even call the cops.

Living proof that God does not want all people to be happy. Poor guy.

I read a cool piece about a statistical analysis comparing 148 females (18-22 years) cell phone records vs ovulation patterns.

There is some unusual information that will become apparent when people take the time to grind the data and make the connections.

Science daily, I believe was the site.

More calls to men when they were ovulating, I take it?

That would have been my guess too, that is what got my attention.

In fact, what they found was a dramatic drop in frequency the number of calls, and duration of calls, between ovulating females and their fathers. When ovulation ended, call normalcy returned to normal. As I recall, it was 148 females over a 6 month span.

The conclusions are not some rathole I need everyone here kicking my a$$ about for all night. Science daily news, it must still be there.

In other words, men who are comfortable being men. I agree. I'd like to see more of them.

I have to say that a pretty horse is enthralling much longer than a "pretty boy".

Different men.

When ovulating some are not opposed to a "booty call", but when later in the cycle they are calling their "friends".

I’m not trying to kick anyone’s ass. I went to google and looked it up. The sample was actually 48 women, and the speculation was that calls to Dad dropped during ovulation in a subconscious biological move to avoid that thar inbreeding.

My advice is simple: marry a person who, though a member of the opposite sex, would be your best friend.

Physical beauty is fleeting. Be objective and look for deeper qualities.
