Probably the most important methodology that Keirsey Temperament Theory has is to watch observable human action to infer Temperament.
Recognizing long term patterns of human action is how one can have a better understanding and insight into the human condition.
Movie clips can give a good illustration of human action, and can highlight Temperament.
Here is a great clip on the behavior of an Inspector Guardian -- A Logistical Contender. The "good" and "bad" at the same time. The movie October Sky is great movie in observing an Architect Rational, Homer Hickam, and his father, an Inspector Guardian.
