It's easier to read mens' faces — here's how you can determine if he's cheated
1,500 study participants play Spot the Cheater
- Male philanderers faces give them away slightly more often than female faces do.
- Study tests idea of being able to spot competition as an evolutionary aid to protecting our relationships.
- The most reliable — though not very reliable — cue is sexual dimorphism.
It's become a standard TV and movie trope. One friend looks at another and suddenly blurts out, "You just got some!" In real life, though, it's not so easy to tell, apparently. This goes double for cheaters, even if you might think you can just look at someone's face and know if they're unfaithful — it's fun to make snap judgements and talk trash, right?
Researchers from the University of Western Australia wanted to know just how good people are at keeping their little secret a secret, and have published the results of their study in the journal Royal Society Open Science. It turns out that it's hard to tell if someone's cheating or ready to poach your partner based on their appearance alone. If you can tell, though, it's more likely you're looking at a man — women's faces are even harder to read.
189 possibly faithful people scrutinized
The researchers recruited 1,500 heterosexual white participants and asked them to fill out questionnaires in which they picked out the cheaters from 189 photographs — 101 men and 88 women, each of whom had let the researchers in on whether or not they'd been philandering. The participants also answered some questions to help the researchers understand each their reasons for tagging a photo model as a cheater.
The study cites previous research that suggests that "women, and to a lesser degree, men, show above-chance accuracy in judging sexual unfaithfulness from opposite-sex faces." This conclusion was borne out in the new study, though this wasn't the main objective.
One aspect of protecting one's relationship is the ability to spot competitors, and so the new research looked at our ability to spot a tendency toward infidelity in same-sex candidates who might poach our partners.

Good guesses, bad guesses
It turned out that men and women were both more accurate with their judgement of men's faces when it came to spotting a likelihood of cheating or poaching. Women's faces, on the other hand, pretty much baffled everyone. In terms of detecting same-sex cheaters, men did better identifying untrustworthy men than women did spotting female philanderesses. "We found very little evidence of any accuracy in impressions of faithfulness from women's faces," says the study.
Still, we're not so good at this game overall, it turns out. The study finds, "Even though accuracy for men's faces was statistically significant, the level of accuracy was modest at best." Over 80% of participants exhibited a less-than-chance accuracy level in their conclusions. For men's faces, only 14.1 to 18.0% of participants did better than chance. For women's faces, the percentage of good guessers was even lower: 0.9 to 4.0%.

Visual cues that affected opinions and how useful they were
The researchers asked participants about the importance of three characteristics as cues of unfaithfulness:
- sexual dimorphism — essentially the physical size of the person being judged
- attractiveness — the visual appeal of the person's face
- untrustworthiness — whether or not the face simply looked untreatable
All three led participants to decide a man was likely to be a cheater or poacher. In assessing women, attractiveness and trustworthiness were factors.
As to whether these three indicators were of any use assessing a propensity for infidelity or poaching, the story was a bit different.
"The face plays an important role in human mate choice as a signal of various aspects of quality, including genetic quality, diet, fertility, aggressiveness, and parental care," says the study. Nonetheless, attractiveness turned out not to have been a reliable indicator of cheating in the study's data. According to the the photo models' self-reporting, good-looking people were no more likely to be unfaithful than others.
As it turns out, only dimorphism accurately indicated mate cheating/poaching.

The study concludes, "In summary, our results suggest that there might be some kernel of truth in impressions of unfaithfulness from men's faces. This above-chance accuracy for men's faces is consistent with the evolutionary prediction that accuracy in our judgements of unfaithfulness from strangers' faces might represent an evolved adaptation for identifying potential male cheaters/poachers." At the same time, the high level of inaccuracy means — in a devastating blow to trash-talking — "we should not rely on our first impressions to make diagnostic judgements of unfaithfulness in everyday situations."
Innovation in manufacturing has crawled since the 1950s. That's about to speed up.
Here's why you might eat greenhouse gases in the future.
- The company's protein powder, "Solein," is similar in form and taste to wheat flour.
- Based on a concept developed by NASA, the product has wide potential as a carbon-neutral source of protein.
- The man-made "meat" industry just got even more interesting.
