左撇子更有创造力？百年研究数据说“不”

Core Viewpoint - The long-held belief that left-handed individuals are more creative lacks scientific support, according to a comprehensive review of over a century of research conducted by scientists at Cornell University [1][2]. Group 1: Research Findings - The analysis of nearly 1,000 studies revealed that left-handed individuals do not show an advantage in standard divergent thinking tests, and in some scenarios, right-handed individuals perform better [1]. - In highly creative professions, the proportion of right-handed practitioners is significantly higher, contradicting the notion of left-handed creativity superiority [1]. Group 2: Misconceptions and Explanations - The research team identified three reasons for the persistence of the belief in left-handed creativity: 1. The "minority association effect," where left-handed individuals and creative geniuses are both minority groups, leading to causal associations [2]. 2. The "tortured artist myth," which links the higher prevalence of left-handedness in the arts with mental health issues, reinforcing stereotypes [2]. 3. The "selective attention trap," where people focus excessively on fields like art and music, where left-handedness is slightly more common, while ignoring overall data [2].
