You might be psycho if you take your coffee like this!
1,000 people were surveyed, asking them to give their food and flavour likes. The participants then took a series of personality tests assessing antisocial personality traits, such as sadism, narcissism and psychopathy.
The closest association was between bitter foods and “everyday sadism” – that is to say, enjoyment of inflicting moderate levels of pain on others.
So if you take your coffee plain black….watch out! You might be psycho!
