This chapter is devoted to convey a single but powerful idea: Our system 1 is constantly monitoring our environment checking that everything falls into an expected order of things. When something happens that doesn’t fully fit into it, system 1 generates a surprise feeling and immediately begins to find a casual explanation for that fact.
We humans are kind of machines of finding causal explanations of everything that happens around us. There are two kinds of set of rules that are applied to finding causalities. One of them applies to the way physical objects interact among them. This rules include movement, impact, velocity, pushing, being pushed, falling, etc… There is another set of rules that is used to understand the interactions between human beings. Here we use categories completely different: help, explain, pretend, love, betrayal, hope, etc…
This idea, that we are machines desperately looking for a story is very Talebian and, in fact Kahneman uses an example from Taleb in the chapter. As Talebian is also the idea that this human tendency is a source of cognitive bias in the sense that system 1 generates lots of spurious ideas that, if not checked thoroughly by system 2 (and remember that system 2 is too lazy and too busy for thoroughness), will be a cause of erroneous judgment.
Let’s see how this concept develops in future chapters.
