Give me 11 Minutes and I'll Make you Dangerously Persuasive

Episode Timeline

   Persuasion is a learnable method, not magic, and the most persuasive people are ambiverts rather than strong extroverts.

   • A Wharton study of software salespeople found that strong extroverts sold less than almost anyone, strong introverts also underperformed, and ambiverts—people in the middle of the introversion-extroversion spectrum—were the real stars.
   • Ambiverts know when to talk confidently and when to listen attentively, and since most people are ambiverts, the myth that you must be a loud, outgoing personality to persuade is false.

   Explaining why dramatically increases compliance, even when the reason is meaningless.

   • In the 1977 Harvard copy machine study, adding a real reason ('because I'm in a rush') raised compliance from about 60% to 94%, and even a nonsensical reason ('because I have to make copies') still got 93% to say yes.
   • A Harvard study found cafeteria cooks made better-tasting food when they could see the people they were serving on a live iPad feed, showing that reasons work far beyond office equipment.

   Social proof—copying the behavior of similar people in similar situations—is a powerful persuasion lever.

   • A Phoenix hotel study found that signs citing what other guests do ('almost 75% of guests who stay here reuse their towels') raised towel reuse from about 30% to roughly 44%, and a room-specific version raised it even further.
   • Because we take cues from people like us when uncertain, persuaders should focus less on what people should do and more on what people actually do.

Key Concepts

• ambivert— The sweet spot between introversion and extroversion that produces the most persuasive people.
• social proof— The psychological lever that makes us copy the behavior of people like us in uncertain situations.
• rhyme as reason effect— Rhyming statements feel truer because they are easier for the brain to process.

Notable Quotes

• The shocker, the strong extroverts generally were terrible. They sold less than almost anyone.
