所以不同的结构点对你的人生有着不同的影响。事实上，我们的实验结果表明，朋友数量的差异有46%都是可以通过基因得以解释。这并不奇怪。因为我们知道，有的人生来腼腆，有的人生来合群。这是显而易见的。但我们也发现了一些不是那么明显的东西。比如，你的朋友们是否认识彼此，其中47%的差异都是和你的基因有关。你的朋友们是否认识彼此不仅仅和他们自己的基因有关，也和你的基因有关。我们认为其中的原因就在于有的人喜欢把自己的朋友介绍给彼此──没错，说的就是你──而其他人喜欢把朋友们分开，不喜欢介绍给彼此。所以有些人将他们身边的网络们编织在一起，构成了紧密相联的深层网络，而他们则是舒服地身处其中。最后，我们甚至发现人们是身处网络中心还是边缘，30%的差异也是和他们的基因相关。所以你是在中心还是边缘，有一部分是遗传的。

Now, what is the point of this? How does this help us understand? How does this help us figure out some of the problems that are affecting us these days? Well, the argument Id like to make is that networks have value。 They are a kind of social capital。 New properties emerge because of our embeddedness in social networks, and these properties inhere in the structure of the networks, not just in the individuals within them。 So think about these two common objects。 Theyre both made of carbon, and yet one of them has carbon atoms in it that are arranged in one particular way -- on the left -- and you get graphite, which is soft and dark。

But if you take the same carbon atoms and interconnect them a different way, you get diamond, which is clear and hard。 And those properties of softness and hardness and darkness and clearness do not reside in the carbon atoms; they reside in the interconnections between the carbon atoms, or at least arise because of the interconnections between the carbon atoms。 So, similarly, the pattern of connections among people confers upon the groups of people different properties。 It is the ties between people that makes the whole greater than the sum of its parts。
