Left-handed people are not more creative than right-handed people, despite what most of us have heard. A 2025 meta-analysis reviewing the full body of evidence found no support for the idea that left-handers or mixed-handers outperform right-handers on standard creativity tests. In fact, right-handers scored slightly higher on one widely used measure of creative thinking. The belief turns out to be one of the most persistent and well-liked myths in popular psychology.
What the Testing Actually Shows
The most common way researchers measure creativity in a lab is through divergent thinking tests, which ask people to generate as many novel uses for everyday objects as possible. On the Alternate Uses Test, the most standard version of this task, right-handers scored statistically higher than left-handers across the pooled studies. That’s the opposite of what the myth predicts.
Results on the Torrance Tests of Creative Thinking, another major battery, are similarly flat. One study found left-handers scored higher on a single sub-measure called “figural elaboration,” which involves adding detail to drawings. But a separate study using the same test found no differences on any of its ten verbal and figural components. When you zoom out across decades of research, the pattern is clear: handedness doesn’t reliably predict creative ability in either direction.
Why the Myth Feels So True
If the evidence is this clear, why does nearly everyone, left-handers and right-handers alike, believe left-handers are more creative? Researchers at Cornell point to several interlocking reasons.
The first is what they call left-handed exceptionalism. About 10% of the population is left-handed, and creative genius is also rare, so the brain naturally links the two unusual things together. The second is a pattern of statistical cherry-picking that has compounded over the years. Left-handers do appear to be slightly overrepresented in two specific creative fields: visual art and music. People noticed this, generalized from it, and the idea stuck. But being overrepresented in two professions is not the same as being more creative overall. It’s a sampling error dressed up as a fun fact.
There’s also a cultural thread tying left-handedness to the “tortured artist” archetype. Left-handers experience higher rates of depression and schizophrenia, and society has long romanticized the link between mental illness and artistic genius. That association, even though it has nothing to do with creativity itself, gave the myth extra staying power.
Are Left-Handers Overrepresented in Creative Professions?
The professional data is messier than people assume. An early and frequently cited study from the 1970s reported that 29% of architecture faculty at one school were left-handed, nearly three times the population rate. That number got repeated widely. But a larger follow-up study found 10.2% of professional architects and 11.5% of architecture students were left-handed, both figures perfectly in line with the general population. The dramatic early finding came from a sample of just 17 people.
This pattern, small or biased samples producing exciting results that larger studies fail to replicate, runs through the entire literature on handedness and creative careers. The professions where left-handers do show up at higher rates (certain areas of visual art and music performance) may reflect advantages in spatial processing or motor coordination rather than creativity per se.
The Brain Science Behind the Idea
The neurological theory that originally fueled the myth isn’t baseless, it’s just been misapplied. Creativity does rely on communication between the brain’s two hemispheres. The bundle of nerve fibers connecting them, called the corpus callosum, plays a dual role in creative thinking. During the early phases of working on a problem, it helps each hemisphere operate independently, exploring different types of information at the same time. Then, during the “aha” moment of insight, it facilitates rapid integration between the two sides.
People whose corpus callosum has been surgically severed or who were born without one show reduced capacity for creative problem-solving and imaginative thinking. So cross-hemisphere communication genuinely matters for creativity. The leap that doesn’t hold up is assuming left-handers have more of it. Left-handers do show some differences in how their brains are lateralized, but those differences don’t translate into better creative performance on any reliable measure.
What Handedness Does Affect
Left-handedness does come with real neurological differences, just not the ones the myth highlights. Research using brain imaging on left-handers who were forced to write with their right hand as children (a common practice in earlier generations) reveals that these “converted” left-handers show extra activation in motor planning areas of the right hemisphere. Their brains appear to work harder to suppress left-hand movements and initiate right-hand writing, even decades later. The degree of extra brain activity correlates with how strongly left-handed the person originally was.
This tells us something important: handedness reflects deep-seated brain organization that doesn’t simply go away with practice. But that organization relates to motor control and movement planning. Extending it to creativity requires a chain of assumptions that the data doesn’t support.
Where This Leaves Left-Handers
None of this means left-handers can’t be creative. It means handedness isn’t a useful predictor of who will be. Creativity is influenced by personality traits like openness to experience, by training, by environment, and by motivation. Your dominant hand doesn’t appear to be part of that equation in any meaningful way. The roughly 10% of the population that is left-handed produces its share of artists, scientists, and innovators, but not because of their handedness. The myth is appealing precisely because it offers a simple biological explanation for something as complex and varied as human creativity.
