If you like your coffee black rather than all milky, foamy and syrupy then many will say you’re simply drinking it as it’s meant to be drunk.

However, if you have a fondness for the bitter tipple then it could be a sign that you’re a psychopath, according to research.

Scientists studying taste buds have found parallels between the consumption of some of our favourite drinks like bitter IPAs, black coffee and tonic water and malevolent personality traits.

So you might want to be wary if you’ve got a friend or partner who shuns milk and sugar in their cup of Joe.
