In this interview from the 2026 Bainbridge Community Foundation Annual Financial Education Series, Paul sits down with Bill Bernstein — neurologist, financial historian, and author of The Four Pillars of Investing and If You Can — for a wide-ranging conversation drawn from 50-plus years of investing experience.

Bill explains why you're only rewarded for taking risk in well-regulated markets (and why crypto doesn't qualify), how today's market echoes the late 1990s, why the "reverse glide path" makes sense the older you get, and what the Bessembinder research really tells us about the cost of trying to pick winners. Paul and Bill also debate withdrawal strategies, the case against long bonds, and whether tilted small-value investing still works once "the bozos know about it."

A masterclass in evidence-based investing from one of the most respected voices in the field.
