Weapons of Influence #3: Social Proof (Ep. 193)

The time has come to jump back into Robert Cialdini’s Influence: The Psychology of Persuasion. This time, we’re talking about the wisdom of the crowd.

Like both of the mental tricks we’ve covered so far in this series, following the rule of social proof is usually a good idea. But like all good things, it can backfire when you least expect it — both as a perfectly innocent coincidence and as a result of the ever persistent salespeople of the world.

Anyway, thousands of other people are going to be listening to this episode, so I shouldn’t have to convince you. It’s just got to be good, right?
