Coffee enthusiasts who prefer it black might possess some darker personality traits, as revealed by an intriguing study. Researchers discovered a correlation between a fondness for bitter flavors and characteristics such as everyday sadism or psychopathy. But what does this really imply?

If you enjoy black coffee, you might think it’s simply a matter of health or a preference for simplicity. Perhaps you appreciate the strong, unfiltered flavor. However, according to recent research from the University of Innsbruck in Austria, your choice could reflect something more profound about your personality—something that might surprise many.
The researchers propose that there could be a relationship between a passion for bitter tastes and darker personality traits. This includes behaviors associated with narcissism, sadism, and psychopathy.
The study involved 953 adults from the United States. Participants disclosed their taste preferences across sweet, sour, salty, and bitter categories. Following this, they took personality assessments that evaluated traits like narcissism, aggression, psychopathy, sadism, and other antisocial behaviors.
Upon analyzing the results, a distinct pattern emerged. Individuals who favored bitter tastes more than others were also more inclined to exhibit what psychologists refer to as “malevolent personality traits.”
So, how does a preference for bitter flavors relate to darker behaviors? Researchers found that a stronger liking for bitter foods, such as black coffee, dark chocolate, or even gin and tonics, was associated with a greater presence of sadistic or psychopathic traits.
Both phases of the study reinforced this connection. According to the published abstract, there was a notable link between a taste for bitterness and a heightened tendency toward cruelty or emotional detachment. The most consistent association was found with “everyday sadism.”
Everyday sadism doesn’t involve committing crimes or intentionally harming others. It’s a psychological term that describes individuals who derive some pleasure from cruelty, even when it’s not genuine.
For instance, an individual with this characteristic might find enjoyment in violent movies, graphic video games, or narratives involving torture. While they may not inflict harm in reality, they often feel intrigued or entertained by scenarios that encompass suffering or violence.

Psychopathy differs from typical sadism, although the two can frequently intersect. The National Library of Medicine states that psychopathy encompasses traits such as:
- Low empathy
- Shallow emotions
- Impulsive behavior
- A propensity for antisocial actions
Individuals with psychopathy typically do not experience guilt or fear in the same way as others. They may initially appear charming, but they often exploit others for their own benefit.
The research indicated that those who prefer black coffee might be more likely to exhibit these traits. This doesn’t imply that every black coffee drinker is a psychopath, but it could hint at a certain emotional detachment or a darker aspect of their personality.
The study didn’t focus solely on black coffee. It also examined other foods and beverages such as:
- Dark chocolate
- Radishes
- Tonic water
- Strong alcoholic beverages like gin or whiskey
The unifying factor? Bitterness.
Enjoying these strong, sometimes off-putting flavors may indicate a personality that is more at ease with discomfort, or even drawn to it.
Not quite. The research doesn’t claim that consuming black coffee makes you dangerous or harmful. Rather, it suggests that there could be personality patterns linked to taste preferences.
Consider it more as a reflection of personality rather than a diagnosis.

Additionally, the researchers noted that people’s food choices are influenced by more than just flavor. Often, we consume items because we have developed a liking for them. Cultural influences, social contexts, or previous experiences can all impact our consumption choices.
Many individuals don’t appreciate their first taste of coffee. The same applies to wine, beer, or spicy foods. However, over time, they may come to love it. This phenomenon is known as taste adaptation.
Some individuals might steer clear of certain foods not due to a dislike, but rather because they are costly, unhealthy, or difficult to obtain. Therefore, having a taste preference doesn’t necessarily equate to frequent consumption.
This is a crucial point to consider when analyzing the study. Enjoying a food and actually consuming it are often two different things.
The research team aimed to explore how our taste preferences could reflect our inner characteristics. They discovered that individuals with a stronger affinity for bitter flavors were more inclined to exhibit traits associated with cruelty or emotional detachment.
However, the researchers acknowledged that personality is multifaceted. No single trait or food can encapsulate a person entirely. This was merely one piece of a larger puzzle.
Additionally, since the study involved a substantial sample size, it provided a relatively comprehensive view of American adults, but it should not be seen as a global conclusion or definitive statement.
So, what implications does this have for your morning coffee?
If you savor black coffee, it could indicate a bold and unapologetic personality. Perhaps you appreciate intensity or simplicity. Or, as suggested by this study, there might be a part of you that leans towards emotional detachment, an interest in darker themes, or even a hint of everyday sadism.
But don’t worry. Enjoying black coffee doesn’t make you a villain. It simply makes you… human. Complex, intriguing, and full of surprises.
