Attractive women not only get away with many unfair advantages, they can also easily manipulate men and take advantage by unfair means, shows a Chinese research.

Men are more likely to accept an unfair financial proposition offer when it comes from a beautiful woman, with thinking faculties getting clouded by beauty. Men are unable to discern fair from unfair.

In the study, 21 male students at Zhejiang University were asked to view 300 photographs of the faces of Chinese women -- half of whom were attractive and half unattractive as rated by a different group of men.

This was followed by a computer game in which they engaged with women in a financial proposal.

The men were more likely to accept any offer from attractive women, with a small difference being that they took time over unfair ones. But attractive women had an edge over unattractive ones in scoring with unfair proposals.

The brain scans also revealed greater reward activation when the attractive women proposed offers, as well as a heightened sensitivity and dissatisfaction with unfair offers from unattractive women.

The study results also imply men are nice to attractive women even when chances of dating them are low. The men were aware they wouldn't meet any of the women even as they accepted unfair proposals.

"This suggests our motivations to be nice to attractive people are unlikely to be based on conscious decisions to maximize our own benefits," says University of Stirling psychologist Anthony Little to Huffington Post.

"The results are in line with previous findings in the area: people behave nicely toward attractive people," says Little, who was not involved in the study.

As he notes, attractive people can get away with mean acts as their beauty shields them.

The research was recently published in the journal Frontiers in Neuroscience.

Men are also attracted by a woman in heels as she looks taller, more sexually confident, sure of herself, with a lengthened silhouette and "sensual jutting buttocks" in the words of a Paris-based sociologist.

They will go out of their way to help and even answer annoying surveys taken by such women on the streets, revealed a study by Universite de Bretagne-Sud.
