The Klontz–Chaffin model overview

Ben Felix and Braden Warwick are joined by Dr. Charles Chaffin, a leading voice in financial psychology, to explore why investors so often act against their own best interests—and how better tools and frameworks can help bridge the gap between rational plans and real human behavior. The conversation blends behavioral finance, goal setting, and risk profiling, while also introducing a new evidence-based risk tolerance questionnaire now being made publicly available to listeners. The episode digs into why humans are wired for short-term survival rather than long-term optimization, how biases and environment shape financial decisions, and why coaching—not transactions—is becoming the advisor's most important role. Charles explains concepts like money scripts, financial flashpoints, identity-based goals, and financial self-efficacy, tying them directly to investing behavior and client outcomes. The discussion also goes deep on financial risk tolerance: what it really is, why people consistently misjudge it, and why psychometric tools outperform traditional questionnaires.
