Soooo...we're psychopaths apparently.
A study carried out by Professor Christina Sagioglou from Innsbruck University has found that people who enjoy bitter tastes such as black coffee and tonic water are more likely to have psychopathic tendencies.
The study asked 500 men and women to rate the tastes of a number of sweet, salty, bitter and sour products while answering questions about their personality, such as would a statement like "given enough provocation, I may hit someone" apply to them.
The questions were based around trying to find out if they had any of the traits of Machiavellianism, psychopathy and narcissism.
As it turns out, the people who preferred the bitter tastes were actually more likely posses those tendencies than the people who preferred the sweeter tastes.
The study claimed that 'general bitter taste preferences emerged as a robust predictor for Machiavellianism, psychopathy, narcissism and everyday sadism', while Dr Sagliogou said that the enjoyment of bitter tastes was like ‘a rollercoaster ride where people enjoy things that induce fear.
'We found particularly robust correlations with everyday sadism, which is a construct related to benign masochism – the enjoyment of painful activities.'
