A recent study conducted by the University of Innsbruck in Austria found that black coffee drinkers often have psychopathic or sadistic traits.
According to the university, about 1,000 US adults, in two studies, around the age of 35 were surveyed to share their taste preferences were when it came to bitter items such as drinks and food.
Participants in the study answered questions related to personality traits such as psychopathy, narcissism, sadism, and aggression.
Researchers concluded that those who enjoy bitter tastes tend to have an unpleasant demeanor compared to those who have sweet or salty taste preferences.
Furthermore, the study confirmed that bitter taste preferences were “positively associated with everyday sadism and psychopathy personality traits."
