Man-With-Beard and Negative Frequency-Dependent Sexual Selection

[tube]6i8IER7nTfc[/tube]

Culture watchers pronounced “peak beard” around the time of the US Academy Awards in 2013.  Since then celebrities (male) of all stripes and colors have been ditching the hairy chin for a more clean-shaven look. While, I have no interest in the amount or type of stubble on George Clooney’s face, the beard/no-beard debate does raise a more fascinating issue with profound evolutionary consequences. Research shows that certain physical characteristics, including facial hair, become more appealing when they are rare. The converse is also true: certain traits are less appealing when common. Furthermore, studies of social signalling and mating preference in various animals shows the same bias. So, men, if you’re trying to attract the attention of a potential mate it’s time to think more seriously about negative frequency-dependent sexual selection and ditch the conforming hirsute hipster look for something else. Here’s an idea: just be yourself instead of following the herd. Though, I do still like Manuel’s gallic mustache.

From the BBC:

The ebb and flow of men’s beard fashions may be guided by Darwinian selection, according to a new study.

The more beards there are, the less attractive they become – giving clean-shaven men a competitive advantage, say scientists in Sydney, Australia.

When “peak beard” frequency is reached, the pendulum swings back toward lesser-bristled chins – a trend we may be witnessing now, the scientists say.

Their study has been published in the Royal Society journal Biology Letters.

In the experiment, women and men were asked to rate different faces with “four standard levels of beardedness”.

Both beards and clean-shaven faces became more appealing when they were rare.

The pattern mirrors an evolutionary phenomenon – “negative frequency-dependent sexual selection”, or to put it more simply “an advantage to rare traits”.

The bright colours of male guppies vary by this force – which is driven by females’ changing preferences.

Scientists at the University of New South Wales decided to test this hypothesis for men’s facial hair – recruiting volunteers on their Facebook site, The Sex Lab.

“Big thick beards are back with an absolute vengeance and so we thought underlying this fashion, one of the dynamics that might be important is this idea of negative frequency dependence,” said Prof Rob Brooks, one of the study’s authors.

“The idea is that perhaps people start copying the George Clooneys and the Joaquin Phoenixs and start wearing those beards, but then when more and more people get onto the bandwagon the value of being on the bandwagon diminishes, so that might be why we’ve hit ‘peak beard’.”

“Peak beard” was the climax of the trend for beards in professions not naturally associated with a bristly chin – bankers, film stars, and even footballers began sporting facial hair.

Peak Beard

Followers of all things hirsute, particularly male facial hair have recently declared “peak beard”. The declaration means that it’s no longer cool to be bearded (if you’re a man, anyway), since being bearded no longer represents a small, and hence very hip, minority. Does this mean our friends over a Duck Dynasty will have to don a clean-shaven look to maintain their ratings? Time will tell.

From the Guardian:

Hirsute men have been warned their attractiveness to potential partners may fade as facial hair becomes more prevalent, in a scenario researchers have called “peak beard”.

Research conducted by the University of NSW finds that, when people are confronted by a succession of bearded men, clean-shaven men become more attractive to them.

This process also works in reverse, with men with heavy stubble and full, Ned Kelly-style beards judged more attractive when present in a sea of hairless visages.

Researchers picked 1,453 bisexual or heterosexual women and 213 heterosexual men to take part in the study.

Participants were shown 36 images of men’s faces, with the first 24 pictures used to condition the subjects by showing them exclusively bearded or non-bearded men, or a mixture of the two.

The final 12 images then showed clean shaven or bearded men, with the participants ranking their attractiveness on a scale of minus four to four.

Researchers found the ranking of these men strongly depended upon the exposure of participants to bearded men prior to this. The more beards they’d already seen, the less attractive subsequent beards were, and vice versa with clean-shaven men.

This phenomenon is called “negative frequency-dependent sexual selection” and is present in several animal species, according to the UNSW team.

Researcher Robert Brooks told Guardian Australia the aim of the work was to look at the dynamics that drove the fashion of beards.

“There is a lot of faddishness with beards, they are on the way back and it’s interesting to look at that interaction with culture,” he said.

“It appears that beards gain an advantage when rare, but when they are in fashion and common, they are declared trendy and that attractiveness is over.”

Brooks conceded it was hard to tell how the experiment related to the real world, but said the fashion for beards might be reaching its zenith.

“The bigger the trend gets, the weaker the preference for beards and the tide will go out again,” he said. “We may well be at peak beard. Obviously, you will see more beards in Surry Hills than in Bondi, but I think we are near saturation point. This thing can’t get much bigger.

“These trends usually move in 30-year cycles from when they are first noticed but, with the internet, things are moving a lot faster.”

The researchers are now working on a larger, follow-up study that will look at the link between facial hair and masculinity.

“We still don’t really know the primary function of the beard,” Brooks said. “Some women are attracted to it, some are repelled. It is clear it is a sign of manliness, it makes men look older and also more aggressive. How much women like that depends, in a way, on how overtly masculine they like their men.
