鲁达 8月13日是国际左撇子日（International Left-Handers Day）。你身边有左撇子的朋友吗？你知道吗？乔布斯（Steve Jobs）、比尔·盖茨（Bill Gates）、威廉王子（Prince William）、奥普拉（Oprah Winfrey）等等都是左撇子。
我们常常听说这样一种说法，左撇子的人更聪明。这个说法并没有得到科学论证，不过Business Insider的一篇文章称，左撇子的人确实在某些方面更出色。
There are certain cognitive domains where left-handed people do seem to excel. One such area is called "divergent thinking," or the ability to generate new ideas based on existing information.
左撇子的人确实在某些特定领域更出色，比如发散性思维。
That's according to 1995 research by psychologist Stanley Coren, which was cited more recently in a New Yorker article. Coren conducted several experiments that suggest left-handedness is associated with superior divergent thinking, at least in men.
1995年心理学家Stanley Coren的研究证明了这一观点，他的研究也在近期被New Yorker引用。Coren做了一系列实验，证明了左撇子人群——至少是男性左撇子人群——在发散性思维方面的擅长。
More recent research, cited in the New Yorker article, has found that lefties demonstrate superior spatial skills, mental flexibility, and working memory.
New Yorker的这篇文章同时还指出，左撇子人群在空间能力、思维灵活性和工作记忆等方面也表现更出色。
Although none of these findings prove that lefties are more intelligent, they do suggest that they have certain cognitive advantages. Those advantages may influence not only their performance in psychological experiments, but also the professional paths they pursue and the areas they thrive in.
尽管这些科学研究并不能证明左撇子更聪明，但至少证明了他们在某些方面的优势，这些优势不仅会让他们在心理学实验中表现更出色，也有可能让他们在工作和专业领域更突出。
