Introduction

Rationally Speaking is the podcast where we explore the borderlands between reason and nonsense. Today's guest is Tim Urban, author of Wait But Why - a long form stick figure illustrated blog that covers life, the universe, and everything. Before today's episode, I have a message for our listeners: check out givewell.org. They do rigorous research on which charities are actually effective. If you're curious, you can read their explanations of how they reach their conclusions at givewell.com.
