A Baylor University study in 2015 discovered that people with psychopathic personality traits were significantly less likely to engage in sympathetic yawning--i.e. the response where one person feels compelled to yawn because he witnesses another person doing it.
The researchers believe that the lack of empathy which is one of the trademarks of a psychopath is the reason for the non-yawn. They have not gone as far as to assert, however, that should you see an individual fail to mirror to another's yawn, you must automatically presume that the non-responsive individual is a serial killer burying his victims in his basement.
