Dr. Lewis Mandell Empirical Retention Decay (Ages 16–28) Financial Knowledge vs Decision Real-World Timing
The Mandell Paradox (Cited in Source Evidence): Longitudinal research showed mandated high school personal finance had negligible impact on 25-year-old financial decisions when taught in abstract high school isolation. Retention decays sharply unless reinforced with just-in-time applied modules when students actually rent apartments, borrow student loans, or sign auto financing.
