This episode decodes the precise science of measuring human behavior, emphasizing the critical need to rely on objective data rather than intuition or assumptions about a client's underlying emotions. The discussion breaks down how to create operational definitions that are clear, unambiguous, objective, and complete, highlighting the practical "act it out" test to ensure a targeted behavior is not open to interpretation.
