Contagious yawning has been linked to empathy levels in several studies. However, new research in the journal Personality and Individual Differences finds that people with psychopathic traits—especially a lack of empathy—are not as susceptible to catching a case of the yawns. Jeff and Anthony discuss whether not "catching" a yawn makes you a psychopath, and specifically what that means for their own yawning habits.
