With the Six Hats method, we try to do only one thing at a time. We do not try to do everything at the same time. With color printing, each color is printed separately, one at a time, and in the end the full color effect is obtained. Underneath all this is the absolute physiological need to separate out the types of thinking. As I mentioned in the introduction, the brain is sensitized to look for danger and sensitized to seek benefits through a different chemical setting.
Airplanes coming in to land often fly over car parks.
If you tell yourself to notice the yellow cars, then suddenly the yellow cars pop up and make themselves visible. That is an example of sensitization. You cannot be sensitized in different directions at the same time, so when we set out to do all aspects of thinking at the same moment, we are going to be suboptimal on all of them. All the points mentioned in this section may seem obvious and logical. In fact, there is no mystery about them.
