On the other hand, the research did reveal a few intriguing facts about the extremes of the spectrum. The study noted a slightly greater rate of left-handedness in people with intellectual disabilities, indicating that “atypical handedness” can, in a certain sense, be linked to different developmental routes. The study also went against the common stereotype that left-handed people are more likely to be “gifted.” In fact, hight-achieving groups are in fact slightly less likely to be left-handed than the general public.
This change in the narrative means we shouldn’t see left-handedness as either a “superpower” or a “deficit,” but as a neutral biological variation. While lefties may not have a naturally higher IQ compared to the rest of the population, their advantage lies in the way they use their intelligence, especially in what is termed “spatial rotation” or “divergent thinking,” where the right hemisphere of the brain gets a workout.
Creativity and artistic ability
One of the most enduring beliefs about left-handed people is that they are more creative than the rest. According to a common psychological theory found on Enviroliteracy, the right hemisphere of the brain, which is used for spatial reasoning and intuition, is said to be more dominant in left-handers, which might give them an advantage in music and art.
Research published in Behavioral and Brain Functions, indicates that left-handed musicians have distinctive structural brain features such as increased gray matter in the auditory cortex which may help with skills such as pitch memory.
However, scientific opinion seems to be shifting to a more nuanced way. A 2025 Cornell University meta-analysis conducted by Owen Morgan and Daniel Casasanto, which reviewed more than 100 years of data and nearly 1,000 studies, found that while leftie do dominate in fields like music and art, they do not actually perform better on standard lab tests that measure “divergent thinking,” which is the ability to come up with more solutions to a single problem. It seems that the “creative lefty” belief only persists because our tendency to notice rare traits like being left-handed and being a genius and assume they somehow just go hand-in-hand.
The athletic advantage of left-handers
When to comes to left-handers and sports, it has long been considered that they have strategic advantage over the rest of the people. In “duel” sports like fencing, baseball, and table tennis, lefties are represented at far higher rates than their 10% share of the overall population. A2025 study published in Royal Society Open Science, shows that left-handers are significantly overrepresented in elite fencing—particularly in the foil and épée disciplines—where they make up over 25% of top-ranked male athletes.
This is because of the “Negative Frequency-Dependent Advantage” or “surprise effect.” The overwhelming majority of people, or 90%, are right-handed, and most of them spend their entire lives playing against right-handed opponents. The “southpaw” effect causes their muscle memory to be slightly off because of the angles and spins involved.
However, a newly published research from February 2026 published in the journal Scientific Reports indicates that there is also a psychological element to this phenomenon. Namely, the study shows that left-handers actually have a higher “hyper-competitive orientation” than right-handers. What this means is that lefties are less likely to shy away from a competition due to nervousness or anxiety and are driven by a desire to win. So not only they are harder to predict, but they also have a sharper appetite when it comes to one-on-one combat.
