Hänger galenskap och kreativitet ihop?

Ja, det verkar så:

John Nash1. Researchers … have found high levels of psychopathology… in writers, poets, visual artists and composers …
2. Family studies have produced evidence of creative interests and aptitudes in close relatives of psychiatric patients …
3. Research on psychiatric patients … suggest that they have enhanced performance relative to control participants on tasks that require divergent thinking. …
4. A new theory based on genetics suggest that gene mutations that increase a person’s risk of developing mental illnesses … have been preserved, even preferred, during human evolution, due to their relationship with creativity. …
5. Symptoms of certain disorders like hypomania (mild mania) favour creativity by giving a boost to the imagination and energy.

Hur är det med forskare: föreligger ett samband även där mellan galenskap och kreativitet? Eller sållas de galna ut av de mer strikta formerna för vetenskaplig verksamhet?
