Study: Psychopaths drink their coffee black

At least, that’s according to a new study published in the journal Appetite, which found a correlation between a love of black coffee and sadist or psychopathic tendencies.

The research surveyed more than 1,000 adults, asking them to give their food and flavour preferences. The participants then took a series of personality tests assessing antisocial personality traits, such as sadism, narcissism and psychopathy.

The study, carried out by researchers at the University of Innsbruck, found that a preference for bitter flavours was linked to psychopathic behaviour.
