Delicioso (parte II)

Parte I.
"This tendency to underestimate the complexity around us is now a well-studied aspect of human psychology and it is underpinned, in part, by the so-called narrative fallacy.
You see the narrative fallacy in operation when an economist pops up on the early-evening news and explains why the markets moved in a particular direction during the day. His arguments are often immaculately presented. They are intuitive and easy to follow. But they raise a question: Why, if the market movements are so easy to understand, was he unable to predict the market movement in advance? Why is he generally playing catch-up?
That is the power of the narrative fallacy. We are so eager to impose patterns upon what we see, so hardwired to provide explanations that we are capable of “explaining” opposite outcomes with the same cause without noticing the inconsistency.
But think about what this means in practice. If we view the world as simple, we are going to expect to understand it without the need for testing and learning. The narrative fallacy, in effect, biases us toward top-down rather than bottom-up. We are going to trust our hunches, our existing knowledge, and the stories that we tell ourselves about the problems we face, rather than testing our assumptions, seeing their flaws, and learning. But this tendency, in turn, changes the psychological dynamic of organizations and systems. The greatest difficulty that many people face, as we have seen, is in admitting to their personal failures, and thus learning from them. We have looked at cognitive dissonance, which becomes so severe that we often reframe, spin, and sometimes even edit out our mistakes.
But when we are misled into regarding the world as simpler than it really is, we not only resist testing our top-down strategies and assumptions, we also become more defensive when they are challenged by our peers or by the data. After all, if the world is simple, you would have to be pretty stupid not to understand it."
Isto faz lembrar Taleb e os fragilistas.
