mic stand Comedians show high levels of psychotic personality traits, and an unusual personality structure could be the secret to making other people laugh, according to new research.

A study by researchers from the University of Oxford and Berkshire Healthcare NHS Foundation Trust, published in the British Journal of Psychiatry, found that comedians score significantly higher on psychotic personality traits compared to the general population.

Researchers recruited 523 comedians to take part – 404 men and 119 women. The participants were recruited from comedy clubs, comedian agencies, associations and societies mainly in the UK, USA and Australia. 

All the comedians were asked to complete an online questionnaire designed to measure psychotic traits in healthy individuals. The four different aspects measured by the questionnaire are: Unusual Experiences (belief in telepathy and paranormal events), Cognitive Disorganisation (distractibility and difficulty in focusing thoughts), Introvertive Anhedonia (reduce ability to feel social and physical pleasure, including an avoidance of intimacy) and Impulsive Non-Conformity (tendency towards impulsive, antisocial behaviour).

The questionnaire was also completed by 364 actors – another profession used to performing in front of an audience – who acted as a control group. The comedians’ and actors’ questionnaire results were compared to each other, and to a general group of 831 people who had non-creative occupations.

The researchers found that comedians scored significantly higher on all four types of psychotic personality traits compared to the general group. Most striking was their high scores for extraverted personality traits, as measured by the Impulsive Non-Conformity scale, and introverted personality traits, as measured by the Introvertive Anhedonia scale. The actors scored higher than the general group on three types – but did not display high levels of introverted personality traits. 

The researchers believe that this type of unusual personality structure may help explain comedians’ ability to entertain.  

Creative thinking

Professor Gordon Claridge, of the University of Oxford’s Department of Experimental Psychology, said: “The creative elements needed to produce humour are strikingly similar to those characterising the cognitive style of people with psychosis – both schizophrenia and bipolar disorder. Although schizophrenic psychosis itself can be detrimental to humour, in its lesser form it can increase people’s ability to associate odd or unusual things or to think ‘outside the box’. Equally, manic thinking, which is common in people with bipolar disorder, may help people combine ideas to form new, original and humorous connections.

“Our study shows that, as creative people, comedians rate highly on the same personality traits as those regularly observed in other creative individuals. The traits in question are labelled ‘psychotic’ because they represent healthy equivalents of features such as moodiness, social introversion and the tendency to lateral thinking.”
