Don and Tom dive into the human obsession with prediction—especially in finance—and why models fail us more than they help. They dissect the CAPE ratio, Fama vs. Shiller, and why “knowing” the market is a fool’s errand. Listeners also get lessons on ETF pricing myths, market cap misunderstandings, SEP Roth IRAs (spoiler: they’re basically unicorns), and whether dad deserves a gift or just more responsibilities.
