1. Contrast
Some kind of contrast will be extremely useful in helping you find the crucial distinctions operating. Whenever possible make everything the same except the presence or absence of what you are modeling.
- You can compare the same person before and after they made a change—whether spontaneous or deliberate.
- You can compare two recent experiences in the same person when they did, and didn't, have the skill or quality you are modeling.
- You can compare two people, one of whom has it and the other doesn't.
