Bitter taste preferences are positively associated with antisocial personality traits.
Bitter taste preferences most robustly predict everyday sadism.
Results suggest close relationship between the gustatory system and personality.
If you like to drink black coffee, you may be coffee drinker who likes strong flavours, seek health benefit of black coffee, or just wants to drink the coffee the way it’s supposed to be drunk.
Or, maybe you’re a psychopath.
According to a new study published in the journal Appetite, found a correlation between a love of black coffee and personal traits to be sadist or psychopathic tendencies.
The study surveyed more than 1,000 adults, asking them to give their food and flavour preferences. The participants then took a series of personality tests assessing antisocial personality traits, such as narcissism, sadism and also psychopathy.
The study, carried out by researchers at the University of Innsbruck, found that a preference for bitter flavours had a link to psychopathic behaviour.
The closest association was between bitter foods and “everyday sadism” – that is to say, enjoyment of inflicting moderate levels of pain on others.

And it is not just only black coffee that has a link to psychopathic – the study also found participants who reported a fondness for radishes, celery and tonic water were also more likely to exhibit antisocial traits.
This is not the first time research has found a link between taste and personality.
Previous studies have shown sweet taste experiences increase “agreeableness” and eagerness to help, while bitter taste experiences increase hostility and elicit harsher moral judgments.

The researchers Christina Sagioglou and Tobias Greitemeyer believe this association may “become chronic” in people who have a strong liking for bitter flavours, and lead them to have more hostile personalities.
So if your next Tinder date orders strong, black coffee at the end of a meal, or reaches over for a stick of celery, you have been warned.
