A fascinating overview of research into creativity from Brainpickings blog:
One of the most interesting chapters in the book deals with the correlation between creativity and mental illness, bringing scientific rigor to such classic anecdotal examples as those evidenced in Van Gogh’s letters or Sylvia Plath’s journals or Leo Tolstoy’s diary of depression or Virginia Woolf’s suicide note. Having long opposed the toxic “tortured genius” myth of creativity, I was instantly intrigued by Andreasen’s inquiry, the backdrop of which she paints elegantly:
Did mental illness facilitate [these creators’] unique abilities, whether it be to play a concerto or to perceive a novel mathematical relationship? Or did mental illness impair their creativity after its initial meteoric burst in their twenties? Or is the relationship more complex than a simple one of cause and effect, in either direction?
She cites the work of Havelock Ellis, one of the earliest scholars of creativity, a Victorian physician, writer and social reformer ahead of his time. In 1926, in his late sixties, he published A Study of British Genius, an effort to provide a scientific assessment of the link between genius and psychopathology by studying a sample of people found in the British Dictionary of National Biography — a compendium of about 30,000 eminent public figures, whom he sifted through a set of criteria to identify 1,030 displaying “any very transcendent degree of native ability.” Andreasen recounts his findings( Popova)
