Is There A Biological Basis Of Narcissism?

New Research has shown that people with a higher levels of testosterone that the average for their gender may be more inclined to abuse their power.

Could this be a biological basis of narcissism and corruption? In the study, people with a higher than average level of testosterone for their gender agreed with statements such as “I insist on getting the respect that is due to me” and “There is nothing wrong with occasionally taking credit for one of your subordinates’ ideas" than others. I would think the ability to rationalize away perjury and criminal activity would also be characteristics of such people.

We all know narcissists. They are the people who believe it is better to get than give. They are the ones who leach off others rather than being charitable. They are the ones who demand good service from others yet never give it. They are the ones who believe the world owes them a living. They are the ones who refuse to even take care of their own children despite being perfectly able to do so. They are the ones intolerant of others yet demanding extreme tolerance for their own actions.

Of course having a higher than average amount of testosterone doesn't make you a narcissist but is likely a factor in predisposing you to narcissism. Sadly narcissism is one of the most difficult predispositions to overcome.
