Down side of testosterone:
Sex hormone connected with greater reliance on gut instincts and less self-reflection
... the hypothesis that higher levels of testosterone increase the tendency in men to rely on their intuitive judgments and reduce cognitive reflection—a decision-making process by which a person stops to consider whether their gut reaction to something makes sense. The researchers found that men given doses of testosterone performed more poorly on a test designed to measure cognitive reflection than a group given a placebo.
"What we found was the testosterone group was quicker to make snap judgments on brain teasers where your initial guess is usually wrong,"...
"The testosterone is either inhibiting the process of mentally checking your work or increasing the intuitive feeling that 'I'm definitely right.'"
... the cognitive reflection test ...
... the group that received testosterone scored significantly lower than the group that received the placebo, on average answering 20 percent fewer questions correctly. The testosterone group also "gave incorrect answers more quickly, and correct answers more slowly than the placebo group," the authors write. The same effect was not seen in the results of the basic math tests administered to both groups. The results "demonstrate a clear and robust causal effect of [testosterone] on human cognition and decision-making," they conclude.The results "demonstrate a clear and robust causal effect of [testosterone] on human cognition and decision-making."
The researchers believe that the phenomenon they've observed can be linked to testosterone's effect of increasing confidence in humans. Testosterone is thought to generally enhance the male drive for social status, and recent studies have shown that confidence enhances status.
"We think it works through confidence enhancement. If you're more confident, you'll feel like you're right and will not have enough self-doubt to correct mistakes," Camerer says.
Camerer says the results of the study raise questions about potential negative effects of the growing testosterone-replacement therapy industry,...
"If men want more testosterone to increase sex drive, are there other effects? Do these men become too mentally bold and thinking they know things they don't?"
