EPISODE 126 | Cognitive Biases and the Brain: Thanks, Evolution! (Because Reasons 11)

The first of two episodes looking at cognitive biases - this one at how memory works and how we prevent input overload by filtering out information. Hopefully, this will give us some insight into why people think they way they do.

The primary source material for this is the Cognitive Biases Codex, created by Buster Benson and John Manoogian III, as used by the EU's Marie Curie CogNovo program for Conspiracy-Theories.EU.
