手指的研究 2021/09/03
No Plagiarism!3Hunuqc74tTgdJeXwydCposted on PＥNAＮＡ

這兩天，和同事討論一些有關手指的研究。別會錯意，說的不是中指，而是研究食指和無名指長度的比例，學名是指長比（digit ratio）。科學家認為，指長比是胎兒時期雄激素濃度的指標。指長比越低，也就代表食指比無名指短得越多，那男性化的特徵便較明顯。故此，男性的指長比相對女性為低。

有研究顯示，指長比低的女性較有同性戀傾向，而男性則不存在這關聯。不過，指長比的研究並不止於性別或性取向。有趣的發現包括：低指長比的足球員表現更好，低指長比的男學生數學成績更優異，而女學生則有更好的語言能力。

同事說了一個英國的研究，一些業績好的證券交易員，他們的成功並不是由於對證券價格的準確評估，只是這些人無名指比食指長，有較高的冒險傾向。我說下次一定要找低指長比的人打麻將，那當我做大牌時，一定有人出銃。
