In this talk, Julia introduces a metaphor of soldiers and scouts to describe two very different approaches to thinking. To illustrate these two mindsets in action, she tells the story of the Dreyfus Affair: how one man was wrongfully convicted of treason, and how another realized this fact and fought to exonerate him. 

Julia Galef co-founded the Center for Applied Rationality, a nonprofit devoted to developing cognitive science-based strategies for reasoning and decision-making. For the last six years, she has hosted the Rationally Speaking podcast.
