When you have come to a conclusion based on the facts and interpretations at hand continue to collect more information and continually test the conclusion.
Resist the bias to ignore information that doesn’t support the conclusion.
Your conclusion is your best guess at a model for understanding. Continually test the model with additional data.
Too often, once we come to a conclusion, we stop looking. When we stop looking we end up with conclusions that are sub-optimal or are no longer relevant.
