It is commonly known that mental illness constitutes a source of profound harm. It relates to individual suffering, distorts one’s cognitive, emotional and behavioural processes, and sometimes leads to severe impairment. However, the results of more recent psychological studies indicate that psychiatric disorders might be linked to particular benefits as well as causing pain.
There has been a well-researched relationship between bipolar disorder and creativity. It is believed that certain clinical symptoms brought by the illness, for example thought speed or openness for new experiences, may contribute to enhanced creativity (see for instance Ghaemi, 2011; Andreasen, 2005; Jamison, 1996). (For more details see my interview with Greg Currie.) If that were true, we would have the grounds to believe that bipolar disorder brings certain epistemic benefits. At the same time the illness may cause cognitive impairments in other areas of functioning, for example it may affect memory, sleep and concentration. The idea that pragmatic or psychological harm may coexist with the benefits of an epistemic kind is relatively new in psychiatry, thus researching it seems very exciting.
