In his book 'Thinking: fast and slow' Daniel Kahneman introduces the concept that our brains have two separate systems, the first one is fast thinking and is what we use to recognize danger and decide whether to fight or flee, the second one is slow and is what we use to analyze complex situations: buying a car or a house. The problem is that system 1, to use Kahneman's terminology, is always on and always making judgments, jumping to conclusions on the merest amount of evidence. It doesn't evaluate the quantity or quality of the evidence, it just takes what it has and comes up with a conclusion. It doesn't search our memory for additional facts that might contradict or even confirm its conclusions. It acts as if 'What you see is all there is,' or WYSIATI. Unless we make a decision to engage system 2 then we are at the mercy of system 1.
This genetic predisposition has profound implications for the Orient phase of the OODA loop. Left unchecked system 1 can open the door to all kinds of filters and biases that will screw up our evaluation of a given situation. Causing us to make poor decisions. We need to discipline ourselves to always question what our first reaction to information is. Ask ourselves is this all the information there is? What is the quality of this data? Are there other facts available to help me to better analyze this situation? It takes time and effort but it is what a master politician or strategist does.
