Apparently you're a psychopath if you like black coffee.
A study from the University of Innsbruck found those who like bitter tastes also showed signs of having anti-social personality traits.
Researchers conducted two studies with more than 1000 adults. Participants were asked to write down food and flavour preferences and undertake a personality test that examined anti-social behaviours like narcissim, psychopathy and sadism.
Turns out those who liked bitter flavours, like black coffee, showed stronger signs of having those anti-social personality traits than somebody who didn't like bitter flavours.
It's not just black coffee drinkers you need to watch out for either. The research found people who liked radishes, celery and tonic water also showed signs of anti-social personality traits.
