Think Again: Bullet Point Summary, Notes, and Quotes

  1. In 1949, smokejumpers parachuted into a Montana forest to contain a wildfire but soon had to flee for their lives. Their leader Wagner Dodge survived by improvising an escape fire to drain the wildfire's fuel in the area while most of his crew thought he was crazy and perished trying to outrun the flames. This tragedy highlights the importance of mental flexibility that is increasingly vital for success in our rapidly changing world.
  2. Know how to rethink and unlearn. Always doubt your convictions and be open to change your mind.
    1. “The purpose of learning isn't to affirm our beliefs; it's to evolve our beliefs.”
    2. Mike Lazaridis created the BlackBerry, which became hugely popular as a wireless communication device focused on email, but he failed to rethink and adapt it as the smartphone market evolved, leading to BlackBerry's precipitous decline. In contrast, Steve Jobs initially resisted making a smartphone but was persuaded by his engineers to rethink, resulting in the revolutionary iPhone which fueled Apple's massive success.
  3. Even constitutions have amendments.
  4. We tend to fall into four categories when communicating: preachers (push our own ideas), prosecutors (relentlessly argue to be correct), politicians (people pleasers), and scientists (embrace limits, are curious, learn by testing hypotheses, accept new truths). Be like a scientist.
  5. “If knowledge is power, knowing what we don't know is wisdom.”
  6. Study shows that what differentiated eminent scientists from their peers was their cognitive flexibility (willingness “to move from one extreme to the other as the occasion requires”).
  7. “Research reveals that the higher you score on an IQ test, the more likely you are to fall for stereotypes, because you're faster at recognizing patterns. And recent experiments suggest that the smarter you are, the more you might struggle to update your beliefs.”
  8. Imposter syndrome is the feeling that you are not as competent as others believe you to be.
    1. Halla Tómasdóttir, a businesswoman with no political experience, struggled with impostor syndrome when asked to run for president of Iceland. Embracing her doubts, Halla ran an open and positive campaign, connecting with voters. Though she didn't win, she vastly overperformed by receiving the second most votes (27.9%) despite lack of campaign budget and media coverage.
    2. Imposter syndrome can be beneficial, as it can motivate us to work harder and learn more.
  9. Overconfidence often stems from ignorance of our limitations, whereas modest doubts can motivate us to work harder, work smarter, and learn from others.
    1. Study shows that people who consider they know more than others significantly overestimated their own knowledge. (Dunning-Kruger effect)
    2. “Those who can't… don't know they can't.”
  10. “You can be confident in your ability to achieve a goal in the future while maintaining the humility to question whether you have the right tools in the present. That's the sweet spot of confidence.”
  11. Self-assurance without self-awareness breeds arrogance, but humility paired with confidence helps us recognize our blind spots, question assumptions, and continuously grow and learn.
  12. Detach your opinions from your identity, then you can more easily admit being wrong because your identity wouldn't be broken.
    1. Ted Kaczynski, the Unabomber, went from a professor to a domestic terrorist because he was so stubbornly attached to his opinions.
  13. “Who you are should be a question of what you value, not what you believe. Values are your core principles in life -- they might be excellence and generosity, freedom and fairness, or security and integrity.”

    1. People who disagree readily can be valuable in prompting rethinking and challenging assumptions. However, they need to be managed to avoid tipping into personal conflict.
  17. Effective disagreement involves focusing on "how" things work rather than "why" we believe what we do. This reduces defensiveness and fosters curiosity about alternative viewpoints.
  18. Harish Natarajan, a world champion debater, faced off against Project Debater, an AI system built by IBM. Despite the computer's massive knowledge base, Harish is able to change more minds by finding common ground, asking the audience questions, and expressing some uncertainty. Unlike the computer's declarative statements, Harish's questions and humility engaged the audience in thinking for themselves.
  19. Use the collaborative approach when arguing: find common understanding, ask non-judgmental questions, and have flexible thinking. People are less receptive when you bully them with logic and facts.
  20. Treat disagreements as a dance rather than an adversarial war -- you have to be open-minded and willing to adapt your moves to get into rhythm with the other person.

  23. Motivational interviewing is an effective method to help someone rethink. It involves open-ended questions and reflective listening (acknowledging others' views and feelings) to help them find their own motivation to change. Don't force people with logic or lectures.

    1. An empathetic doctor was able to convince an anti-vaxxer to vaccinate all her children.
    2. Ugandan politician Betty Bigombe was able to convince brutal warlord Joseph Kony to engage in peace talks.
