Are left-handers more creative than right-handers? In both popular belief and scientific literature, left-handedness is linked with higher creativity. In a qualitative review supported by meta-analyses, here we evaluated whether left- or mixed-handers are more creative than right-handers, as measured by tests of divergent thinking, and evaluated whether left- or mixed-handers are overrepresented in creative professions. We argue that plausible mechanisms for a link between creativity and handedness can be found within influential theories of the neural basis of creativity. However, we found no evidence that left- or mixed-handers are more creative than right-handers; on the contrary, right-handers scored statistically higher on one standard test of divergent thinking (the Alternate Uses Test). Additionally, although left- and mixed-handers may be overrepresented in Art and Music, they are underrepresented in creative professions, in general. Both right and left-handers tend to believe that left-handers are more creative, but this belief is not supported by the available empirical evidence.
左撇子比右撇子更具创造力吗?在大众观念和科学文献中,左利手都与更高的创造力相关联。在一项有元分析支持的定性综述中,我们评估了在发散性思维测试中,左利手或混合利手是否比右利手更具创造力,并评估了左利手或混合利手在创造性职业中是否占比过高。我们认为,在有影响力的创造力神经基础理论中,可以找到创造力与利手之间存在联系的合理机制。然而,我们没有发现证据表明左利手或混合利手比右利手更具创造力;相反,在一项发散性思维标准测试(替代用途测试)中,右利手的得分在统计学上更高。此外,虽然左利手和混合利手在艺术和音乐领域可能占比过高,但总体而言,他们在创造性职业中占比过低。右利手和左利手都倾向于认为左利手更具创造力,但现有实证证据并不支持这一观点。
