"Badger game?" find scientific basis

Canada's psychologists but according to experiment confirmed this for a long time for pretty woman of prejudices: men may really be no reason to not relinquished beauty.

In the "36 meter" in the "Badger game" theory and history of the tried-and-military strategist.

There is an old saying in China called "Fatale", since ancient times because of the State, the Kings Nvse, Dukes from stage to the DPRK from the Kings not earlier, the list goes on and on. However it has been just people's experience. Recently, Canada of experimental psychologists, but according to the confirmed this for a long time for pretty woman of prejudices: men may really be no reason to not relinquished beauty.

Biologists have long known that can only be gained after the enormous benefits that the animals were more like those of vested interests, even if those benefits compared to the interests of the future might be.

This is called "future interest discount" selection process, are also present in human activities, and many of the economic model. For individuals, a thing of value will change over time.

For example, you can get cash in hand, than the future will hold for the same amount of money to "worthless" (this is why the Bank will pay us interest, but once the total amount of the payment by instalments is much smaller because).

However, if the future could get more money, it may be worth the wait. This logic is the so-called "rational" discount. However for some people, they shown is not a "rational" and irrational discount.

For example, for drug addiction, they prefer to receive 2 today's heroin, you do not want to wait until the next day get 5 g; although 5 grams of more than 2 grams of heroin to meet their needs.

Canada McMaster University's Magdalena · Wilson · Daley and Martin decided to study the behavior of this discount, would like to know this kind of rational thinking when people face the specific attraction of time will not be applicable.

Their experimental results found that the temptation by beauty, men tend to become "shortsighted": to male students looked pretty girls photos, they prefer short-term smaller interests, rather than wait for the future will be of even greater results.

Participate in testing the students look at a number of specific photos, these photos are from the Internet, and sexy.

After seeing photos, these students are given a chance to win money, they can choose to test the next day for a 15-35 Canadian cheque, or is in the next day get a sheet of 50 – 75 Canadian dollars.

Wilson and Daley found those who see the plain of the men and women photo and they responded with a regular "discount curve".

This means they make is rational. In the male who looked pretty girls photos, they "irrational" in reducing the future return value: they will select the next day get the cheque, instead of waiting to get more money. On the contrary, participate in the trial of female students whether see frogs or handsome guy, will make a decision about.

"We haven't been able to find the ability to interpret test results of psychological mechanism," Magdalena · Wilson said: "However we assume watch Belle photo will gently stimulates the sexual select the neural mechanisms.

"But some of the theory of evolution is that this phenomenon and select relevant: in order to obtain more attractive partners, men to take greater risks. Because the risk factor, so they will return in future reduce the return value.

However, regardless of the final explanation how the men and for their own mistakes found a new basis for the defence, will cause feminist vigorously denounced.

These scientific ethics discussion we put aside for the time being, if so, love jiangshan loves beauty really is a fish and bear paw no co-existence of challenges.
