A recent study has found that people with psychopathic traits tend to have reduced smell power. When it comes to identifying smell, people with psychopathic traits score poor, believe the researchers of Macquarie University.

The findings of the recent study have been published in the renowned pages journal Chemosensory Perception. The researchers while writing in the journal said, "Olfactory measures represent a potentially interesting marker for psychopathic traits, because performance expectancies are unclear in odor tests and may therefore be less susceptible to attempts to fake good or bad responses".

It is not for the first time when studies have been conducted over people with psychopathic traits. Previous studies have showed that people with psychopathic traits find it difficult to plan things and to behave well in society.

Besides, this year, a study conducted by the researchers of King's College London's Institute of Psychiatry showed that psychopath criminals have a different brain structure as compared to a normal person's brain. It is hoped that findings will help researchers in finding out as to how the psychopathic criminal should be treated so that they don't pose any threat to the innocent lives. In the coming times further studies will also take place to understand the behavior of psychopaths.
