Do you drink your coffee black? Congratulations ā you may be an anti-social psychopath. A new study from the University of Innsbruck found a link between a love of black coffee and sadist or psychopathic tendencies. Apparently itās the fondness for bitter flavors that was linked to psychopathic behavior. Researchers found a link between liking bitter foods and āeveryday sadismā ā or inflicting moderate levels of pain on others.Ā And itās not just black coffee. Participants who enjoyed radishes, celery and tonic water were also more likely to exhibit antisocial traits.Ā (Independent)
