A new study from the University of Innsbruck in Austria has found that those who like black coffee have a higher chance of being a psychopath.
The study surveyed over 1000 people and found that those that preferred more bitter tones in their food "scored higher on a series personality questionnaires that assessed Machiavellianism, a term used in psychology to describe personalities that are dark, psychopathic, narcissistic and sadistic."
The study also notes that people who enjoyed more bitter foods such as radishes, celery and tonic water, also showed a higher signs of being a psychopath.
Don't worry though, since the sample size was so small - the researchers say that more studies need to be done to see further correlations.
