You've probably heard that the human brain is divided into two hemispheres — the left and the right. Well, the left side of the brain controls the handedness of righties, while lefty movements are managed by the right side of the brain. Traditionally, the right hemisphere was associated with creative skills, like art, music, perception and even general genius.
So, this variation in brain dominance was supposedly why so many lefties pursue creative pastimes and careers. Some of the most famous left-handed artists include heavy-hitters like Leonardo da Vinci (although it's possible he painted left-handed due to a defect), Raphael and M.C. Escher. Left-handed guitarists are rare, yet the group makes up some of the most influential musicians out there, including Jimi Hendrix, Paul McCartney, Black Sabbath's Tony Iommi and Dick Dale, who's known as the "King of the Surf Guitar" [source: Hall].
However, it's not completely clear that there's a link between handedness and creativity. In fact, there's a lack of concrete scientific evidence to support this long-held theory [source: Jarrett]. Additionally, the brain is more complex than originally supposed — both hemispheres aid creativity, just in different ways [sources: Jarrett, Lombrozo].
However, one study did find that left-handed men exceled at divergent thinking, which is being able to come up with new and interesting ideas based on information presented [source: Coren]. By contrast, most people are convergent thinkers, meaning that we think in an "either/or" manner about problems.
