Client and planner attitudes, values, biases

Human beings do not behave like spreadsheets. When a practitioner constructs a Monte Carlo simulation or optimizes a tax-efficient withdrawal strategy, the mathematics assume a frictionless environment. But as any seasoned financial planner will discover, a mathematically flawless plan is frequently derailed by the architect of its execution: the human mind. Acknowledging that the success of a financial plan relies just as heavily on navigating human behavior as it does on quantitative analysis, The Psychology of Financial Planning was formally introduced as a Principal Knowledge Topic for the CFP exam in 2022.
