How would you operationalize/measure your variables, in order to empirically test the aphorism?

This Discussion is about making a science of behavior. Below, I list a handful of common aphorisms about human behavior. Pick one and answer the following questions:
A. How would you restate the aphorism as a Conceptual Hypothesis?
B. How would you state your Conceptual Hypothesis as a Research Hypothesis?
C. How would you operationalize/measure your variables, in order to empirically test the aphorism?
D. What empirical support exists, regarding this aphorism? Bring in some information from outside the class. Find a study that is relevant to the aphorism and very briefly describe what the authors found.
Ignorance is bliss.
