Can you spot a cheat just by looking at him? A recent study suggests you might well be able to – if you’re a woman looking at a man. The 2012 paper found women were ‘moderately capable’ of gauging a man’s sexual infidelity just by looking at a photo of him for three seconds.
Men, interestingly – given the evolutionary advantage it would offer to avoid bringing up someone else’s children – proved incapable.
Shorter men have lower testosterone levels, so aren’t ruled by their penis and (sad but true) aren’t chatted up as much.
HIS EYES ARE WIDE APART
There’s a correlation between infidelity and the space between men’s eyes. The wider apart they are, the more easily bored he is – and likely to be tempted by anything in a skirt.
Your best bet are guys with close-set eyes. Once he’s committed, he’s far less likely to cheat.
HE’S GOT BUSHY EYEBROWS
Sparse eyebrows equals a low sex drive. Thick and busy brows hint at a sexually excessive personality.
HE’S GOT A BUMPY NOSE
They’re linked to high sex drives and a desire to have ‘kinky’ sex.
HE’S GOT ‘MIRROR MUSCLES’
Men who go to the gym purely to look good, rather than for health or sport reasons, tend to have what trainers call ‘mirror muscles’.
They focus on areas that impress, like big biceps or a six-pack, and forget about places like legs which aren’t on display as often.
This suggests vanity which in turn suggests he’s susceptible to flattery and easier to chat up than a guy who isn’t as into his appearance.
HE’S GOT HUGH GRANT HAIR
Floppy hair – short at the sides and longer at the front – is supposedly a dead giveaway of infidelity, according to one study.
Results suggested men with this hair cut tend to be more self-centred and self-obsessed than the average bloke and least likely to worry about the pain an affair may cause you.
HE’S A BIG DRINKER
OK, it’s not officially about his looks but it is something you can observe. Men who drink no more than the recommended weekly total (sensible drinkers rather than lager louts) are 82 per cent less likely to commit adultery than heavy drinkers.
No prizes for guessing why. Don’t be too smug if your boy’s addicted to caffeine instead: coffee drinkers are twice as likely to be unfaithful.
HIS FACE IS SQUARE RATHER THAN OVAL
An oval face means home and family are important to him. He’s unlikely to stray unless pushed too far.
HE’S A BIG BOY
This also isn’t immediately apparent for obvious reasons and you’ll have to indulge in some foreplay to find out this one.
But basically, the size of a man’s testicles is a scientifically proven indicator of his faithfulness. The bigger they are, the more sperm he produces and the more he’s a slave to his libido.
WHAT TO DO IF THIS SOUNDS LIKE YOUR MAN:
Don’t dump him on the spot. Studies on this sort of stuff (except, weirdly, the testicles) are varied and often contradictory.
But it’s still fascinating, not to mention great dinner party trivia, and quite frankly, with (even a little) evidence for all points, I really would be asking a few questions if he scored in every single category!
