I'm often intrigued by the FiveThirtyEight podcasts on their YouTube channel, but was really enthralled with one of their recent videos , where the topic was Why Misinformation Spreads So Quickly on Social Media . Host Galen Druke interviewed guest Max Fisher for nearly an hour. Fisher has written a book called The Chaos Machine , and listening to them talk about the subject of social media's psychological effects on people was, at least to me, quite fascinating.
