นักค้นคว้ามหาวิทยาลัยกลาสโกว์และสเตอร์ลิงของอังกฤษ พบว่าสตรีไม่ต้องไปโทษใครกับการที่พวกผู้ชายมักจะลูกตาไม่ค่อยอยู่กับที่ ชอบทำตาเจ้าชู้สอดส่ายเรื่อยไป เพราะสาเหตุมาจากวิวัฒนาการที่เพศผู้ต้องการจะผสมพันธุ์ เพื่อจะได้ขยายพันธุ์ให้แพร่หลายออกไป
พวกเขารู้ว่าจากประวัติการวิวัฒนาการของสตรีนั้น พวกเธอมักจะชอบใบหน้าที่คุ้นตาว่าน่าดู ในขณะที่บุรุษมักจะถือว่าใบหน้าที่แปลกออกไปมีเสน่ห์ นักวิจัยได้รู้จากการทดสอบกับกลุ่มผู้หญิง 83 คน และผู้ชาย 65 คน โดยการให้ดูรูปสุภาพบุรุษและสุภาพสตรีอย่างละ 5 คน และขอให้คะแนนตามความสวยงามด้วย และให้ทำแบบเดียวกันอีกรอบหนึ่ง
นักวิจัยพบว่าพวกผู้ชายในรอบที่สองจะกลับให้คะแนนรูปของคนเก่าต่ำลง เพราะรู้สึกว่าคนเก่าสวยและมีเสน่ห์น้อยลง ต่างกับพวกผู้หญิงกลับให้คะแนนรูปผู้ชายคนเดิมสูงขึ้น.

Off the hook: Men can’t help staring at other women because they have ‘evolved to increase their reproductive success’
- Men found familiar women less attractive than pictures of unknown faces
- Women, however, found men more attractive the more familiar their face
- Study concluded that men’s wandering eye is due to evolution and helps ensure a man has plenty of offspring

If you frequently catch your man’s eyes wandering when a pretty woman passes by, don’t blame him – it’s all down to evolution.
New research shows that while women are drawn to male faces that look familiar, men are more likely to rate someone they have never seen before as more attractive.
Psychologists came up with the findings after showing men and women pictures of dozens of different faces. The more women in the study saw pictures of the same man’s face, the more attracted they were to him.
But the men who took part rated the women as less attractive when they saw them for a second time.
Researchers believe the reason may be that men have evolved to maximise their reproductive success by mating with as many partners as possible.
The findings, by researchers at the University of Stirling and the University of Glasgow, shed new light on the way the sexes perceive facial familiarity.
Previous studies looking at how humans are drawn to friends and partners found we are more likely to warm to others with familiar or ‘average’ faces that match the size and shape of the general population.
But the latest research suggests the extent to which that initial attraction lasts differs greatly between the sexes.
The researchers carried out a series of studies to measure changes in attractiveness.
In one, 83 women and 65 men were presented with pictures of five men and five women, one at a time.
They were asked to score them for attractiveness on a seven-point scale.
The participants were shown the pictures a second time but alongside another headshot they had not seen before to provide a distraction.
The results, published in the Archives of Sexual Behaviour, showed women judged the men’s faces as more attractive second time round because they were familiar to them.
But while the men also gave the male images a higher score, they found the women less attractive when there was a new female image to look at.
In a second similar study, volunteers were shown facial images and asked to rate them according to trustworthiness and sexiness.
When the experiment was repeated to see how scores changed, the women rated the familiar male faces as even more trustworthy and sexy but the men slashed their sexiness ratings for women.
Researchers say the results may be partly explained by the so-called Coolidge effect – where men are aroused by the novelty of a new sexual partner more than women.
It’s named after an anecdote attributed to 30th U.S. President Calvin Coolidge.
During a farm visit, when his wife was told there was only one cockerel and many hens because the cockerel would mate several times a day, she reportedly said: ‘Tell that to Mr Coolidge’.
When the president asked if it was with the same hen each time and told no, he allegedly said: ‘Tell that to Mrs Coolidge.’
In a report on their findings the researchers, led by psychology research fellow Anthony Little from Stirling University’s School of Natural Sciences, said: ‘Men found female faces they had already seen as less attractive and less sexy, especially for short-term relationships.
‘There is a tendency for males to pursue a large number of partners as they can dramatically increase their reproductive success by mating with multiple females.’
Psychologist Dr Jane McCartney said it was an evolutionary trait that many men are programmed to have sex with numerous partners.
‘Men are geared to reproduce as much as possible and some take full advantage of that.
‘But from a practical point of view it doesn’t make sense to go round having lots of children with different women.’
