People with bipolar disorder are often very creative.

The claim is that people with bipolar disorder are often very creative, as of 2018-02-01. Judge it against the peer-reviewed research available then (for example Kyaga et al. 2011/2013 Swedish registry studies, Jamison, meta-analyses). True: research consistently shows elevated creativity or over-representation in creative occupations among people with bipolar disorder, so a substantial share is notably creative. Mostly true: research shows an association (for example over-representation in creative professions, especially among relatives or milder forms), but 'often very creative' somewhat overstates its size. Mixed: findings are inconsistent, with an association in some studies and not others. Mostly false: the association is weak or limited to subgroups, or it is unproven and stated as established. False: research shows no association, or lower creativity.

Set before the research began.

   “The mean occupational creativity score of those with bipolar I disorder was significantly higher (4.54) than was the mean of those with no diagnosis of bipolar disorder (3.07). Although significant, these findings also suggest that many people with bipolar disorder are not engaged in creative occupations.”

   “As shown in Table 1, these studies have provided consistent evidence for elevated rates of bipolar disorder in samples of famous individuals.”

   “Although most studies of creative eminence have found some overrepresentation of vulnerability to or diagnoses of bipolar disorder, the degree of association noted in these samples has varied dramatically.”

   “This study provided no evidence for elevations in divergent thinking among those diagnosed with bipolar disorder.”

I rated this claim mostly true. A 2011 independent review reports that people with bipolar I disorder had significantly higher occupational creativity scores than people without the diagnosis (E1). It also says studies of famous people consistently found more bipolar disorder than expected (E2). However, the same review notes that many people with bipolar disorder do not work in creative occupations (E1), that the strength of the link varies widely between studies (E3), and that one study found no rise in divergent thinking (E4). So the research shows a real association, but "often very creative" somewhat overstates how large it is.
