Well, if you take your coffee black, I'm here to tell you that you more than like have psychopathic or sadistic traits. Now before you freak out (like the psycho you are), remember it's only a study and not 100% accurate.

According to WDIV, more than 1,000 adults were surveyed about their taste preferences with foods and drinks that are bitter. To get answers, the adults in the study took four different personality tests that examined traits like narcissism, aggression, sadism and psychopathy. I bet if you're like one of these people that were studied, you're getting super pissed right now. lol

Just as suspected, the study found that people who tend to like bitter foods such as black coffee or tonic water also had personality traits that could be seen as bitter and unpleasant. I know people who like both black coffee and tonic water and it's true, they're very bitter and unpleasant. I'm just kidding, actually, they're mean as hell. LOL

The results of both studies confirmed the hypothesis that bitter taste preferences are 39 positively associated with malevolent personality traits, with the most robust relation to every day 40 sadism and psychopathy.

So there you have it, if you drink black coffee, you're bats*$t crazy.
