A team of researchers from the University of Barcelona and University Autonoma de Madrid in Spain, found that people with symmetrical faces more selfish and they are more likely to be difficult to work with.
As quoted from the Guardian, the owner of more symmetrical facial features - that are considered beautiful, more likely to focus on their own desires and interests.
The team, led by Santiago Sanchez of the University of Barcelona and Enrique Turiegano from the University Autonoma de Madrid, conducted the study with a model of conduct 'prisoners' dilemma' in the laboratory.
Two players were each given a choice to be a 'dove' that reflects a good choice, or 'eagle' with selfish choices and take the chance if other players choose the 'doves'.
The study found that people with more symmetrical faces are less able to work together and tend to expect others to cooperate first. These findings will be presented at the annual meeting of laureates in Lindau, Germany, 23 to 27 August 2011.
According to experts, the explanation is found in the evolutionary process. In the subconscious, people tend to see a symmetrical physical attributes as a sign of better health. And, people generally have symmetrical faces attractive face.
Previous research found that individuals faced symmetrical congenital disease tend to suffer less. That is why they are candidates for a potential partner for a better offspring.
"People with symmetrical faces tend to be healthier and more attractive. They are also more independent, but lack the initiative to cooperate with and seek the help of others through natural selection over thousands of years. This characteristic continues to this day," he said.
In addition, the authors investigated the relationship between the level of cooperation and exposure to testosterone during fetal development. Testosterone is usually associated with aggressive behavior. They found, 'alpha male' is not one that can work together.
But the authors stated, this is only a partial truth of testosterone in cooperative behavior. "Subjects exposed to high exposure to testosterone during fetal development is not worse or better than subjects with an average testosterone. Cooperation is influenced some things."
Through research, the experts hope their research could help the design of public policy.
"If a behavior like smoking, drinking or driving in high speed perceived as part of the search status, economic disincentives such as taxes or penalties will not provide a strong deterrent effect," he said.
