New Delhi: A new study says that male hormone testosterone can make men more impulsive.
Researchers, including those from California Institute of Technology in the US, 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 judgements on brain teasers where your initial guess is usually wrong," said Colin Camerer, Professor at Caltech.
"The testosterone is either inhibiting the process of mentally checking your work or increasing the intuitive feeling that 'I'm definitely right,'" said Camerer.
The study, which is one of the largest of its type ever conducted, included 243 males who were randomly selected to receive a dose of testosterone gel or placebo gel before taking a cognitive reflection test.
