Today we introduce our series on Mob Madness and Mass Delusions. I speak to Rob Henderson, PhD student in psychology and Gates scholar studying moral psychology (not his own) at Cambridge University. Topics include the physical pain of social ostracism, herd mentality, moral foundations theory, whether members of a screeching, seething mob are morally responsible for their activities, and the dangerous downside to creating your own personal echo chamber of like-minded people online. Grab your torch and pitchfork and join us in an intro to a the only series-long celebration of one of our defining human characteristics -- the capacity to whip ourselves into an foaming-at-the-mouth terrified and terrifying irrational frenzy and demolish everything in our path.
