研究：無名指長更適合從事股票交易
Finger length may predict financial success
The length of a man's ring finger may predict his success as a financial trader. Researchers at the University of Cambridge in England report that men with longer ring fingers, compared to their index fingers, tended to be more successful in the frantic high-frequency trading in the London financial district.
Indeed, the impact of biology on success was about equal to years of experience at the job, the team led by physiologist John M. Coates reports in Monday's edition of Proceedings of the National Academy of Sciences.
The same ring-to-index finger ratio has previously been associated with success in competitive sports such as soccer and basketball, the researchers noted.
The length ratio between those two fingers is determined during the development of the fetus and the relatively longer ring finger indicates greater exposure to the male hormone androgen, the researchers noted.
Previous studies have found that such exposure can lead to increased confidence, risk preferences, search persistence, heightened vigilance and quickened reaction times.
In the new study, the researchers measured the right hands of 44 male stock traders who were engaged in a type of trade that involved rapid decision-making and quick physical reactions.
Over 20 months those with longer ring fingers compared to their index fingers made 11 times more money than those with the shortest ring fingers. Over the same time the most experienced traders made about 9 times more than the least experienced ones.
Looking only at experienced traders, the long-ring-finger folks earned 5 times more than those with short ring fingers.
While the finger ratio, showing fetal exposure to male hormones, appears to signal likely success in high-actively trading that calls for risk-taking and quick reactions, it may not indicate people who would do well at other sorts of financial activities, the researchers said.
只要看男性無名指的長度，就可以“預測”他能否成爲一名成功的金融交易員。英國劍橋大學的研究人員日前發表研究報告稱，無名指比食指長的人更適合在倫敦金融區從事高強度的金融交易工作。
而且這種生理影響差不多相當於幾年的工作經驗。由生理學家約翰•M•柯茨領銜的研究小組在本週一出版的《國家科學院院刊》上公佈了上述研究成果。
研究人員稱，此前有研究發現無名指與食指長度的比例與是否擅長足球、籃球等競技體育項目有關。
無名指與食指的長度比例是胎兒在發育過程中形成的，如果無名指相對較長，則表明胎兒在發育過程中較多受到了雄性激素的刺激。
此前的研究表明，這種刺激會使人今後更具自信、敢於冒險、做事持久、警覺性高，而且反應會更加靈敏。
在此項最新研究中，研究人員測量了44位男性股票交易員右手的手指長度。他們所從事的工作需要快速的決斷和反應。
研究發現，在過去20個月中，無名指相對較長的交易員賺的錢爲無名指最短交易員的11倍。在同一階段內，最有經驗的交易員賺的錢約爲最沒經驗交易員的9倍。
如果只在經驗豐富的交易員中進行比較，無名指較長的人賺的錢爲無名指較短者的5倍。
研究人員稱，手指長度比例可反映胎兒期所受雄性激素刺激的水平，儘管可從這一比例中預測人們是否適合從事需要冒風險及迅速反應的高強度金融交易工作，但這並不是說有這種生理特徵的人在從事其它金融活動時也會很出色。
