Real men - greedy!

Women who would like to receive generous gifts on birthdays and wedding anniversaries, do not marry a muscular macho. They have snow in the winter is not questioned. As it turned out during the study, men with high levels of the male hormone testosterone is much less generous than those who have this hormone is not much.

The research team has tested the level of generosity of the 25 students of the Claremont University (USA). The volunteers were asked to use the gel with which normal Testosterone   body doubles. For comparison, another part of the test subjects were given a gel that does not contain anything. None of the study participants did not know whether he got acting gel or pacifier.

Then the students were asked to play a computer game in which one party had to split $ 10 with the other party in any way that will seem fair to the owner money. And the one to whom the "split" the money could either accept them or refuse, calling the proposed amount "unfair."

Each of the students played the role as the owner of the money, and as a target. Testosterone gel used the young men was on average 27% less generous than those who sat on placebo. If the representatives of the second group on average were ready to give the partner $ 2, 15, students with high levels of testosterone become generous only $ 1, 57.

And when the scientists decided to use a more powerful version of testosterone dihydrotestosterone (DHT), it has caused in the test once a powerful tide of greed. Now they have become partners to offer a measly 55 cents at $ 10, although students with low levels of testosterone   We were ready to allocate $ 3, 65.

It is surprising that none of the subjects, apparently never occurred to these poor divide $ 10 equally. We are really not talking about how to give the full amount to the partner ...
