Hot impulsive men who shoot first and ask questions later, were the protagonists of Westerns and police, but new research shows films that it makes sense.

A study conducted by researchers from the California Institute of Technology and the ZRT Laboratory, tested the hypothesis that higher levels of testosterone affects the intuitive judgments, reducing cognitive reflection, decision-making process by which a person stops to think about the sense of action. Researchers found that men who received doses of testosterone, showed weaker results of analyzes on cognitive reflection as compared to placebo.

The study will publish in the next issue of the journal Psychological Science.

The experiment involved 243 men who were randomly selected to receive a dose of testosterone or a placebo before cognitive tests. Also, participants were asked math problems.

Bat and ball cost only $ 1.10. Bit costs $ 1 more than the ball. How much is the ball?

The first answer that comes to mind is that the ball costs 10 cents. But this is not true, because then the bit is worth 90 cents more than the ball. The correct answer is worth 5 cents ball and bat - 1.05 dollars. Person inclined to rely on their instincts are more likely to agree with the first response at 10 cents. However, others understand the initial error by cognitive reflection and then answer correctly.

The results show that testosterone group scored significantly lower scores than the group receiving placebo. She quickly gave incorrect answers and slower - correct. According to the researchers, the phenomenon that they observed, due to the effects of testosterone. It is believed that testosterone increases the social status of the male. Men become more confident, feel right, and less prone to error correction.

According to scientists, the results of the study show the potential adverse consequences of the use of testosterone replacement therapy.
