Earlier this year, Gerard O’Reilly (former rocket scientist and current co-CEO of Dimensional Fund Advisors) was interviewed on our favorite investing podcast, Rational Reminder.  Gerard is obviously brilliant, but he’s also one of the best communicators in the investment world.

For those interested in a deep dive into Dimensional’s methodology, the evidence supporting it, and why we prefer Dimensional’s approach versus traditional indexing, we think you’ll enjoy this extended interview (which starts at the 4:00 mark and lasts for about 1 hour and 50 minutes).
