Modelos mentais, experiência de vida e tomada de decisões (parte III)



A experiência de vida, a familiaridade com as situações, é fundamental para que a intuição funcione durante a tomada de decisões (aconselho a leitura de "High Flyers" de Morgan McCall, livro que já referi várias vezes neste blogue).

"The more patterns (padrões) and action scripts (guiões para a acção) we have available, the more expertise we have, and the easier it is to make decisions. The patterns tell us what to do and the action scripts tell us how. Without a repertoire of patterns and action scripts, we would have to painstakingly think out every situation from scratch. (Estão a ver o problema dos senhores 5%?)
.
Because pattern matching can take place in an instant, and without conscious thought, we’re not aware of how we arrived at an intuitive judgment. That’s why it often seems mysterious to us.
Even if the situation isn’t exactly the same as anything we have seen before, we can recognize similarities with past events and so we automatically know what to do, without having to deliberately think out the options. We have a sense of what will work and what won’t. Basically, it’s at this point that we have become intuitive decision makers.
...
While I have criticized the idea of replacing intuition with analytical strategies of decision making, I certainly don’t believe that intuition can solve all our problems. Analysis has a proper role as a supporting tool for making intuitive decisions. When time and the necessary information are available, analysis can help uncover cues and patterns. It can sometimes help evaluate a decision. But it cannot replace the intuition that is at the center of the decision-making process (although that is precisely what some decision researchers have tried to do).
...
When we are faced with a familiar problem, there is a good chance that the first solution we recognize is going to work. Why? Because in most settings we don’t need the best option—we need to quickly identify an acceptable option. Possibly there might be a better one, but if it takes hours to find and evaluate, then there is no practical benefit from searching for the optimal course of action. As the old saying goes, “Better is the enemy of good enough.”
...
When we looked at their decision making more closely we discovered that they were evaluating a course of action by consciously imagining what would happen when they carried it out. We call this process “mental simulation” because decision makers are simulating and envisioning a scenario—playing out in their heads what they expect would happen if they implemented the decision in a particular case. They build a picture of what they expect, and they watch this picture once, sometimes several times. If they like what they see, they are ready to respond. If they spot a problem, usually they can alter the action script. If they can’t find a way around the problem, they jettison the option and look at the next option in the set without comparing it to any other options."
