Everyone now tries to think of information that is available, information that is needed, questions to be asked, other ways of getting information, and so on. It is extremely important to appreciate the difference between description and direction. A description is concerned with what has happened. A direction is concerned with what is about to happen. It is possible to create tests to determine whether a person is type A or type B, or any similar descriptive discriminations.
Psychologists do that all the time.
That temptation must be resisted. The hats are not descriptions of people but modes of behavior. It is true that some people may be permanently cautious and inclined to look for dangers. It is true that some people might always be bubbling with ideas and others might be better at focusing on facts. People may prefer one mode to another.
