Stardust, Smoke, and Mirrors: The Myth of the Mad Genius
Most myths are popular because they offer quick solutions to the worlds ongoing puzzles, whether found in nature or in the baffling variations in human behavior. This is especially true when a myth is ancient, photogenic, and has a whiff of science about it. The mad genius myth qualifies on all counts, deriving its credibility from expert proponents (hereinafter called mythers) who proclaim the existence of a solid empirical link between great creativity and bipolar disorder, so that those who are blessed with the one must also be saddled with the other. This equation is patently false but too rarely challenged, even by mental health professionals who should know better, for reasons that will soon be explained. Meanwhile, the tragedy of the mad genius myth is that it encourages viewing the genius through a warped, dusty, and generic lens; this not only negates the individualism of societys most exceptional talents, it also diminishes their accomplishments as a product of mental disturbance.
