Shorter feedback time for efficiency

This is a simple theory for social sciences:

Efficiency of a social machanism is inversely related to the time it takes to get feedback for an action.

We can apply this to many social scenarios:

1. Teach kids. Beating is a very primitive way to achieve this. Otherwise, the reaction to a kid's action will take lot of time to reach him.
2. Better coding.
3. Better economy

This principle should be applied in any social system being designed. Examples of social systems: schools, various orgnizations.
