Summary: A comprehensive review of more than a century of research calls into question the long-held belief that left-handed people are inherently more creative. After examining nearly 1,000 studies, researchers found no consistent creative advantage for left-handers; in some standardized tests and in many professions, right-handers performed as well as or slightly better than left-handers.
Left-handed individuals are notably visible in certain creative fields such as art and music, but that overrepresentation does not translate to a broad, population-wide superiority in creative thinking. The persistence of the left-handed creativity myth appears to be driven by selective reporting, cultural narratives, and the romanticized “tortured artist” stereotype rather than robust empirical evidence.
Key Facts:
- No overall creativity edge: The pooled evidence does not show a consistent creative advantage for left-handers.
- Right-hander representation: Right-handed people dominate many of the most creatively demanding professions when examined broadly.
- Origins of the myth: The idea that lefties are more creative likely stems from sample bias, anecdotal examples in art and music, and associations between creativity and mental health.

Overview of the research
Researchers from Cornell University performed a rigorous meta-analysis and qualitative review to determine whether left- or mixed-handed people actually show higher creativity than right-handers. Daniel Casasanto, associate professor of psychology and senior author of the study, summarized the results plainly: “The data do not support any advantage in creative thinking for lefties.”
The team reviewed nearly 1,000 publications dating back to 1900. Many studies were excluded because they did not provide standardized data or deliberately sampled only right-handed participants to produce homogeneous study groups. After applying strict inclusion criteria, the analysis relied on 17 studies that together yielded about 50 effect sizes suitable for quantitative synthesis.
Three commonly used laboratory measures of divergent thinking—tasks that assess the ability to generate multiple, varied solutions to a problem—showed little or no advantage for left-handers. On one widely used test, the Alternate Uses Test, right-handers even scored statistically higher. In addition, while left- and mixed-handers may be more visible in specific creative fields like art and music, they are not generally overrepresented across creative professions as a whole.
Why the myth persists
The enduring belief that left-handed people are more creative can be explained by several interacting factors. First, left-handedness is relatively uncommon—about 10% of the population—so rare traits are often linked in the public mind. Second, anecdotal overrepresentation in high-profile creative domains (for example, some famous artists and musicians who are left-handed) invites generalization from a narrow sample.
Third, cultural narratives that tie creative brilliance to mental health struggles contribute to the stereotype. Left-handers have been reported in some studies to experience higher rates of certain mental health conditions, and this association can feed the “myth of the tortured artist,” reinforcing the false link between left-handedness and exceptional creativity.
Finally, Casasanto and colleagues point to statistical cherry-picking and publication bias: a small number of studies with limited or biased samples have been cited frequently over time, creating a misleading impression of consistent support for the lefty-creativity link. When data from many studies are pooled and analyzed without bias, that apparent relationship largely disappears.

Abstract (summary)
This review evaluated claims that left- or mixed-handed people are more creative than right-handers by examining tests of divergent thinking and representation in creative professions. While theoretical mechanisms could plausibly connect handedness and creativity, the empirical evidence does not support a generalized left-handed advantage. In fact, right-handers performed statistically higher on at least one standard measure of divergent thinking (the Alternate Uses Test). Although left- and mixed-handers may be overrepresented in art and music, they are underrepresented in creative professions overall. Both left- and right-handers commonly believe left-handed people are more creative, but that belief is not substantiated by the available data.
In short, the idea that left-handedness confers superior creativity is an appealing cultural story but not a conclusion supported by current scientific evidence. Future research can continue to explore links between brain organization, cognitive styles, and creative performance, but claims of a general left-hander creativity advantage should be treated skeptically unless supported by comprehensive, unbiased data.
