You might want to start looking for a new coffee date. New research has revealed that those who like it strong and black are more likely to have psychopathic tendencies.
Research by the University of Innsbruck concluded that those who preferred bitter tastes showed signs of antisocial and psychopathic traits.
The study of over 1000 adults asked participants to write down their food and flavour preferences and undertake a personality test. Those who favoured bitter flavours (like long blacks) showed stronger signs of having antisocial personality traits than those who avoided bitter flavours all together.
The study also revealed that those who liked celery, radishes and tonic water also had the same traits.
