Are lefties really more creative? 100 years of data say no

A sweeping review of more than a century’s research upends the popular notion that left-handers are naturally more creative. Cornell psychologist Daniel Casasanto’s team sifted nearly a thousand studies, ultimately finding no consistent advantage for lefties on standard divergent-thinking tests—and even a slight edge for right-handers in some. The myth appears to thrive on coincidence: left-handedness is rare and so is creative genius, plus lefties’ overrepresentation in art and music gets cherry-picked while other professions are ignored.
