In the real world, intelligent people don’t actually babble gibberish like Benedict Cumberbatch in Sherlock.
But the stereotype of the ‘tortured genius’ – as seen in that episode where Cumbersherlock gets off his gourd on drugs – has a grain of truth to it. Researchers analysed Mensa members with high IQs – over 130 – and found that ‘those with high intelligence are at significantly greater risk for the examined psychological disorders’, according to IFLScience. The study examined 3,715 members of American Mensa and found that around 20% had an anxiety disorder – double the figure for the population at large. The researchers believe that the heightened perceptions of intelligent people, ‘may predispose them to certain psychological disorders.’
The researchers, led by Ruth Karpinski of Pfizer College, say that further study is needed to work out exactly why intelligent people may be more prone to such disorders.
