Psychologists conducted an experiment and identified one pattern in appearance that reveals psychopaths and narcissists.
The study was organized by specialists from Canada, Iran, Britain and Switzerland.
The results of the study, published in the Journal of Psychiatric Research, say that a narcissist or psychopath can be identified by the ratio of the length of the index and ring fingers.
For the study, scientists recruited 44 people who were being treated in a psychiatric hospital.
Also, to verify the collected information, a control group of 46 volunteers was formed, who were not found to have any mental disorders.
Research results
Scientists claim that potential psychopaths and narcissists have ring fingers longer than index fingers.
This parameter is believed to determine the level of testosterone and estrogen in the fetus in the womb.
The more testosterone, the longer the ring fingers are than the index fingers.
Earlier we talked about the signs that indicate an intelligent woman.
