Psychologists Christina Sagioglou and Tobias Greitemeyer surveyed nearly a thousand adults in the U.S., asking about their taste preferences and measuring traits such as Machiavellianism, psychopathy, narcissism, everyday sadism, aggression, and the Big Five personality dimensions. Across two groups, those who favored bitter tastes tended to score higher on the darker end of the spectrum – particularly everyday sadism and psychopathy.
In plain terms, people who welcomed bitter flavors were more likely to enjoy causing discomfort to others or manipulating situations for their own benefit. Other taste preferences-sweet, sour, salty-did not show nearly as strong a connection to these traits. Although the effect was modest, it remained significant even after accounting for age, gender, and other taste preferences. Statistically, bitterness emerged as the strongest single predictor within the model.
Why Bitterness Aligns with Darker Traits
Taste is a primal sense, evolved primarily for survival. Bitterness often signals toxins in nature, so infants instinctively reject bitter flavors. Adults who develop a taste for bitterness are, in a way, overriding an ancient biological warning system. This willingness to embrace discomfort can resemble thrill-seeking-a readiness to flirt with unpleasantness for a richer experience.
Psychopathy is often characterized by reduced emotional sensitivity; such individuals feel less internal pain when confronted with distress. If a fondness for bitterness and diminished aversion to discomfort exist along a continuum, it makes sense that these traits would appear together in personality data.

Tempering the Sensational Headlines
Before we start labeling every black coffee enthusiast as a schemer, it’s worth noting that this study found correlation, not causation. The sample size, while respectable, is small compared to the global population of coffee drinkers. Many kind-hearted people enjoy their espresso straight, and many bullies prefer sweeter brews.
Taste preferences are shaped by culture, environment, health considerations, and habit. As Stephen Covey famously said, “Between stimulus and response, there is a space.” Craving bitterness is just the stimulus; what we choose to do with that preference-the empathy we show, the conversations we have-fills that space.
Applying This Insight in Everyday Life
- Observe your choices: When you opt for sharp over smooth flavors, do you also gravitate toward brutally honest feedback, intense movies, or spicy foods? Patterns across senses can reveal your comfort with intensity and risk.
- Balance bitter with sweet: When I prepare a black pour – over, I pair it with a brief gratitude note. This small ritual reminds me to temper my sharper edges with kindness.
- Cultivate empathy: Since psychopathic traits often include low empathy, I make it a habit to ask, “How might this affect someone else?”-especially before sending brisk emails fueled by caffeine.
- Share findings thoughtfully: Discussing this study at work sparked one of our most candid conversations about personality and unconscious bias. Awareness fosters understanding, not judgment.
- Tune into bodily signals: If bitterness once felt harsh but now comforts you, consider what has shifted. Taste can reflect mood, stress levels, or hormonal changes.
Taste as a Starting Point, Not a Judgment
Sheryl Sandberg once said, “We cannot change what we are not aware of, and once we are aware, we cannot help but change.” A preference for bitterness may flag a personality trait worth noticing-but it is not a verdict. Psychologists rely on extensive data to diagnose disorders; your morning coffee doesn’t qualify.
Instead, this insight invites reflection:
- Am I drawn to intensity in other parts of life?
- Do I sometimes push others beyond their comfort?
- How do I respond when situations become emotionally difficult?
If these questions nudge you toward growth, the research has served its purpose.

Savoring Black Coffee Like a Connoisseur
Understanding the nuances of black coffee can deepen appreciation beyond mere caffeine consumption. Professional tasters approach coffee with a multi-sensory method that includes smelling, slurping, locating sensations, and describing flavors.
First, inhale the aroma deeply-notes might range from floral and fruity to nutty or chocolatey. Next, take a deliberate slurp, drawing air in to spread the coffee across your palate and stimulate your olfactory senses. This reveals initial tastes such as sweetness (think honey or molasses), acidity (citrus or tartness), and other flavor elements like spices or earthiness.
Then, notice the mouthfeel: is the coffee creamy, thick, thin, or astringent? Observe how the taste evolves as the coffee cools-does it soften, sweeten, or become more bitter? Finally, pay attention to the aftertaste – does it linger smoothly or dry out quickly? This mindful tasting transforms a simple cup into a rich sensory experience.
Brewing Black Coffee with Care
To bring out the best in black coffee, start with quality beans and the right grind size. Freshly ground coffee is essential. Use about two tablespoons of grounds per 5 to 6 ounces of water heated just below boiling. Let the coffee steep for a few minutes, allowing a crust to form on the surface.
Breaking the crust releases aromatic compounds – lean in and take a deep sniff. Skim off floating grounds and top up with hot water. When tasting, sip with a bit of force to spray the coffee across your tongue and into your nasal passages, capturing a full flavor profile.
Final Thoughts
Our taste buds may whisper hints about our tendencies-perhaps a slight inclination toward seeking intensity or embracing discomfort-but they do not script the narrative of who we are. Human personality is a rich tapestry woven from countless threads: genetics, upbringing, experiences, values, and conscious choices. A fondness for bitter flavors is but one tiny stitch in this vast fabric.
What truly shapes our identity is the way we respond to the impulses and inclinations we discover within ourselves. When that first sharp sip of black coffee sparks a fleeting grimace, it also opens a door to self-awareness. It invites us to ask: How do I handle discomfort in other areas of life? Am I willing to face difficult emotions or conversations head-on? Do I seek out challenges because I thrive on growth, or because I’m drawn to risk without regard for consequences?
Moreover, the act of choosing black coffee can be a metaphor for embracing complexity. Life rarely offers sweetness without bitterness, ease without challenge, or comfort without some measure of struggle. By appreciating the bold, unadorned flavors of black coffee, we might be acknowledging our own capacity to sit with ambiguity and discomfort-and to find richness there.

This connection between taste and personality also underscores the power of mindfulness. Being present with the sensations in our mouth, the aroma filling the air, and the warmth in our hands grounds us in the moment. It reminds us that even small rituals can serve as anchors, helping us navigate the swirl of thoughts and feelings that define our daily lives.
Finally, the choice to drink black coffee can be a quiet act of agency. It’s a reminder that while biology and personality traits influence us, they do not confine us. Each cup offers a fresh opportunity to practice empathy, to engage in thoughtful dialogue, and to cultivate curiosity about ourselves and others.
In essence, the story written by our taste preferences is always a draft, open to revision. The richness of life comes not from the labels we might carry, but from the conscious steps we take after the last sip-steps toward understanding, kindness, and growth. So, whether your palate leans toward the bitter or the sweet, remember: the true flavor of your character is shaped by what you do with the moments in between.
