　　①Building on the basic truth about interpersonal influence, the researchers studied the dynamics of social influence by conducting thousands of computer simulations of populations, manipulating a number of variables relating to people’s ability to influence others and their tendency to be influenced.

　　②They found that the principal requirement for what is called “global cascades”—the widespread propagation of influence through networks—is the presence not of a few influentials but, rather, of a critical mass of easily influenced people.

　　①基于这种人际影响的基本事实，研究者们通过对人群进行的数千次的计算机模拟，对社会影响产生的动力学进行了研究。这一过程中，研究者们控制了诸多的变量，这些变量可归为两类：影响他人的能力和易受到他人影响的程度。

　　②他们发现，那些被称为“风靡全球”的现象——通过人际关系广泛传播的影响——的主要条件不是一小部分“影响力人士”，而是一大部分容易受影响的人。
