Around 1000 adults, both men and women participated in two studies conducted by psychologists Christina Sagioglou and Tobias Greitemeyer.

They were asked to write down how much they enjoyed sweet, sour, salty and bitter tastes. They then took personality tests to assess for antisocial behaviors such as aggression, manipulation, narcissism, psychopathy and everyday sadism.

Researchers were able to find a clear connection between a preference for bitter tastes and antisocial tendencies.

“The results of both studies confirmed the hypothesis that bitter taste preferences are positively associated with malevolent personality traits, with the most robust relation to everyday sadism and psychopathy,” according to the study, recently published in Appetite magazine.

Participants who preferred bitter flavors, such as black coffee, tonic water, radishes, and celery were more likely to exhibit anti-social personalities, as compared to those who preferred sweets.

Previous studies by a number of sociological researchers have shown that there is a direct relationship between what you eat and how others perceive you. For instance, one study concluded that people who like sweet foods are likely to be seen by strangers as agreeable and “nice.”
