Researchers at the Karolinska Institutet have provided compelling evidence confirming the link between creativity and mental illness. The large-scale Swedish registry study replicated a previous finding that biopolar disorder - but not other psychopathologies - is more common in artistic and scientific professions (dancers, researchers, photographers, and authors), and further indicated that authors were specifically more prevalent among those with schizophrenia, depression, anxiety disorders, and substance abuse. Creative professions were also more common in family members of patients with certain psychiatric disorders. Including data from most of the Sweden's population (!), this is considered the most comprehensive study to date. It's not a study of contemplation at all (sorry, folks) - but as someone curious about the similarities between certain mental states cultivated by traditional contemplative practices, the flow states cultivated in indiosyncratic ways by creative professionals, and the occasional psychotic experiences during intensive meditation, this line of research fascinates me.
