The more observations an interpretation can predict the more effective the interpretation.
If an interpretation can specify a path that consistently produces an expected outcome it is an effective interpretation.
Interpretations are models that allow us to face the future with a measure of control.
The simplest interpretation that produces the exact same outcome is the better interpretation. Take away all the clutter and what is left is truth.
The important principle to remember is that any interpretation could be wrong. To always have the best interpretations we must continually test and measure and then refine our interpretations.
