According to a new study of the role of testosterone in business negotiations, if someone's ring finger and his index finger are the same length, look out。一项关于睾丸激素在商业谈判中所起作用的最新研究表明，如果某人右手的无名指和食指一样长的话，那你就得小心了。

Little or no difference in the size of those digits is an indicator of high prenatal testosterone, which tells you two things. First, this is a person who is preoccupied with preserving his status and saving face. Unless you handle his ego with kid gloves, he will be quick to take offense. And second, if you cross him, he will get even。如果这两只手指的长度一样或者非常接近，则说明手的主人出生前体内睾丸激素含量就很高，这又进一步说明两点。首先，此人会不惜一切保全自己的地位，维护自己的面子。除非你时时照顾他的自尊，否则他很容易怀恨在心。其次，你跟他作对，他就会实施报复。

In every case, they found a direct correlation between "digit ratio" and vengefulness: The less of a difference between the two fingers, the greater the urge to get even。他们发现，“手指比例”与报复心之间存在直接关系，无一例外：上述两只手指长度差别越小，报复心越强。

"Testosterone is a hormone associated with status-seeking and a need to save face," "It makes a powerful difference in how people respond to situations.[/en]“睾丸激素是与追求地位和挽回面子的需求有关的荷尔蒙。”该研究报告指出。“人们对各种处境的反应方式也因而有天壤之别。”

"People with low testosterone -- that is, with a noticeable difference in the length of their second and fourth digits -- may perceive that they're being treated unfairly, but they're likely to go sulk in a corner." “睾丸激素少的人，也就是其食指与无名指长度有明显差异的那些人，虽然也会认识到自己遭受了不公平待遇，但他们很可能只会生闷气，而不会采取报复行为。”
