Scientists from Cornell University in the United States have conducted a comprehensive review of the association between dominant hand and creativity over the past century, and found that the traditional belief that "left-handed people are more creative" lacks scientific basis. The relevant research results were published in the latest issue of the Journal of Psychoeconomics Bulletin and Review. The research team systematically analyzed nearly a thousand research data, and the results showed that left-handed individuals did not show an advantage in the standard divergent thinking test; In certain testing scenarios, right-handed hands actually perform better. More noteworthy is that in professional fields that require high creativity, the proportion of right-handed practitioners is significantly higher. According to statistics, left handedness accounts for about 10% of the global population. Although left-handed individuals may theoretically possess certain creative advantages due to their divergent thinking primarily relying on the more active right hemisphere, the results of the meta-analysis were unexpected. The team reviewed nearly a thousand papers since 1900 and found that in three mainstream laboratory tests, the correlation between dominant hand and creativity was minimal; If there is a difference, right-handed hands have a slight advantage. The team emphasizes that existing research data is completely unable to support the popular view that 'left-handed people are more creative'. So, where does this cognitive bias come from? Researchers propose three explanations. Firstly, there is the 'minority association effect': left handedness and creative genius are both minority groups, which can easily trigger causal associations. Secondly, there is the 'pain artist myth' - the high proportion of left-handed individuals in the art world and their association with mental illness reinforces stereotypes. Finally, there is the 'selective attention trap', where people overly focus on areas such as art and music where the proportion of left-handed individuals is slightly higher, while ignoring overall data. The study specifically points out that if all occupational fields are comprehensively examined, the so-called "left-handed creativity advantage" will disappear. (New Society)
