We all have a caveman brain—at least when it comes to navigating the internet. Amanda Montell, author of the new book The Age of Magical Overthinking, joins Offline to explain how the "cognitive biases" that we developed to make snap decisions in prehistoric times aren't well suited to handle the volume and pace of the information era. She and Jon talk about biases like the halo effect, zero-sum biases, and declinism, and identify how these biases have supercharged celebrity fandom, influenced our news media, and made Democrats nostalgic for the George W. Bush era.
