Too Much Testosterone Linked to Inflated Ego: Study
Date:1/31/2012

TUESDAY, Jan. 31 (HealthDay News) -- Testosterone makes people more self-centered and less cooperative, a finding that may explain why group decisions can be affected by dominant individuals, researchers report.

Their study included 34 females who had never met. The women were divided into 17 pairs and asked to complete a series of tasks designed to assess their levels of cooperation.

The findings were published in the Jan. 31 issue of the journal Proceedings of the Royal Society B.

"Our behavior seems to be moderated by our hormones -- we already know that oxytocin can make us more cooperative, but if this were the only hormone acting on our decision-making in groups, this would make our decisions very skewed," Wright explained.

"We have shown that in fact testosterone also affects our decisions, by making us more egotistical. Most of the time, this allows us to seek the best solution to a problem, but sometimes, t
