Beer Goggles Myth Busted: Alcohol Doesn’t Alter Attraction

Summary: Researchers have debunked the “beer goggles” myth, suggesting that alcohol doesn’t necessarily make people appear more attractive due to facial symmetry. In their study, participants, including intoxicated individuals, rated natural faces as more attractive than asymmetrical ones.

While alcohol impaired the ability to detect facial symmetry, it didn’t influence attractiveness judgments. This challenges the long-held belief that alcohol blurs the perception of facial attractiveness, indicating that other factors besides symmetry play significant roles in perceived appeal.

Key Facts:

1. The study found alcohol impairs symmetry detection but doesn’t affect attractiveness judgments.
2. Participants consistently rated natural faces as more attractive, regardless of their intoxication level.
3. The research suggests attractiveness is influenced by factors beyond facial symmetry, countering the traditional “beer goggles” theory.

If you thought blurry eyes were to blame for the “beer goggles” phenomenon, think again.

Scientists from the University of Portsmouth have tested the popular theory that people are more likely to find someone attractive while drunk, because their faces appear more symmetrical. 

The term “beer goggles” has been used for decades to describe when a person finds themselves sexually attracted to someone while intoxicated, but not sober.

One possible explanation for the effect is that alcohol impairs the drinker’s ability to detect facial asymmetry, thus making potential partners more visually appealing.

Existing research has shown that a part of what makes people attractive to others is how well both sides of their face match. The thinking goes, the more symmetry the better the gene pool. But when alcohol is introduced, it’s thought a person is less likely to notice if the faces around them are non-symmetrical.

However, a new experiment found that while alcohol did impair face symmetry detection, it had no influence on facial attractiveness judgements. 

Dr Alistair Harvey from the University of Portsmouth’s Department of Psychology, said: “Alcohol is a strong predictor of sexual behaviour, often consumed before or during dates.

“There are a range of possible reasons why alcohol drinkers are more inclined to engage in sex, including a lack of inhibition, heightened expectations, personality traits, and the beer goggles effect.

“Due to the limited research on this topic, we ran a field experiment to help determine why people often experience unexpected – and regretted – sexual escapades after having one too many.”

To gather the results, the team visited a local pub in the Portsmouth area. 99 men and women volunteered for the study, ranging in age from 18 to 62 years old. 

They were asked to rate 18 individual faces for attractiveness and symmetry. Each type of rating was given twice, once for faces showing an enhanced asymmetry, and again for the same faces in their natural form. Participants then judged which of two same-face versions (one normal, the other perfectly symmetrised) was more attractive and, in the final task, more symmetrical.

The study used a robust procedure, taking ratings of individual faces in addition to the usual binary approach where participants select the more attractive or symmetrical face in a pair. 

As predicted, heavily intoxicated individuals were less able to distinguish natural from perfectly symmetrised faces than more sober drinkers. But the more drunk viewers did not rate the faces as being any more attractive. 

As expected, both male and female participants rated natural faces as being more attractive than the ones which were doctored to look wonky. But, surprisingly, this bias was stronger among women.

The paper, published in the Journal of Psychopharmacology, says one possible explanation to the findings could be that attractiveness depends on many factors that simply swamp the small effects of face symmetry.

“We don’t deny the existence of a “beer goggles” effect”, added Dr Harvey.

“But we suspect it would be more easily detectable when using live models for an experiment, instead of static photographs. Images conceal a range of important visual criteria for attractiveness, including build, body shape, height, expression, and clothing.

“Therefore, further research is needed to find the missing piece to the puzzle.”

Abstract

Impaired face symmetry detection under alcohol, but no ‘beer goggles’ effect

Background:

The ‘beer goggles’ phenomenon describes sexual attraction to individuals when alcohol intoxicated whom we would not desire when sober. One possible explanation of the effect is that alcohol impairs the detection of facial asymmetry, thus lowering the drinker’s threshold for physical attraction.

Aims:

We therefore tested the hypotheses that higher breath alcohol drinkers would award more generous ratings of attractiveness to asymmetrical faces, and be poorer at discriminating bilateral facial asymmetry than less intoxicated counterparts.

Methods:

Ninety-nine male and female bar patrons rated 18 individual faces for attractiveness and symmetry. Each type of rating was given twice, once per face with an enhanced asymmetry and once again for each face in its natural form. Participants then judged which of two same-face versions (one normal, the other perfectly symmetrised) was more attractive and, in the final task, more symmetrical.

Results:

Alcohol had no influence on attractiveness judgements but higher blood alcohol concentrations were associated with higher symmetry ratings. Furthermore, as predicted, heavily intoxicated individuals were less able to distinguish natural from perfectly symmetrised face versions than more sober drinkers.

Conclusions:

Findings therefore suggest alcohol impairs face asymmetry detection, but it seems that this perceptual distortion does not contribute to the ‘beer goggles’ phenomenon.
