In Episode 4, we described how the world is complex and ambiguous: we often don't have enough information to make an informed decision, feedback is often terrible, and even if we could calculate an answer, we don't have time. But despite all of this, we still have to make decisions. 在第4章，我们已经描述了这个世界是怎样的复杂与模糊，很多时候我们没有足够的信息来做出一个充分的决定，而且结果往往很糟糕。就算我们可以计算出一个答案，我们却没有足够的时间。但是放开这些不谈，我们仍然需要作出决定。 What do we have to rely on to help navigate this complexity and ambiguity? 我们必须依赖什么来帮助我们解决这些复杂与模棱两可的东西？
