“Think Again: The Power of Knowing What You Don’t Know” by Adam Grant is a book about the importance of rethinking and unlearning in an ever-changing world. Grant, an organizational psychologist, argues that intelligence is not just about knowledge and reasoning but also about the ability to rethink, challenge assumptions, and be open to changing our minds. The book explores how individuals, teams, and organizations can develop a mindset of intellectual humility, curiosity, and adaptability. It is divided into three main parts: Individual Rethinking, Interpersonal Rethinking, and Collective Rethinking, followed by an actionable conclusion.

Detailed Chapter Summaries
Part 1: Individual Rethinking – Updating Our Own Views
This section explores how we can become better at questioning our beliefs and assumptions.
Chapter 1: A Preacher, a Prosecutor, a Politician, and a Scientist Walk into Your Mind
Grant introduces three mental modes that people often fall into:
- Preacher Mode – Defending beliefs as if they were gospel.
- Prosecutor Mode – Seeking to prove others wrong.
- Politician Mode – Trying to win approval.
Instead, he argues we should adopt a scientist mindset, where we test ideas, seek evidence, and embrace being wrong as a step toward better understanding.
Chapter 2: The Armchair Quarterback and the Impostor Syndrome
- People often overestimate their knowledge (the Dunning-Kruger effect) or underestimate themselves (impostor syndrome).
- Grant suggests a balance: confidence in learning while acknowledging gaps in knowledge.
- Embracing doubt can help people stay curious and continue growing.
Chapter 3: The Joy of Being Wrong
- Being wrong is often viewed as a failure, but Grant argues that recognizing mistakes is a strength.
- People should take pleasure in discovering they were mistaken because it means they have learned something new.
- He suggests developing “confident humility”—being open to revising beliefs while remaining confident in the process.
Chapter 4: The Good Fight Club
- Productive disagreements can lead to better decision-making.
- Constructive conflict can challenge assumptions and lead to breakthroughs.
- He introduces the idea of “disagreeable givers”—people who challenge you out of a desire to help.
Part 2: Interpersonal Rethinking – Helping Others Think Again
This section discusses how to encourage others to rethink their views.
Chapter 5: Dances with Foes
- Rather than arguing to “win,” we should aim for collaborative discussions.
- Instead of bombarding opponents with facts, asking curious, open-ended questions can lead to better persuasion.
- Motivational interviewing—a technique used in therapy—can help people change their minds by guiding them to reflect on their own beliefs.
Chapter 6: Bad Blood on the Diamond
- How to navigate conflicts and overcome polarization.
- He shares examples of bridging deep divides by finding common ground and appealing to shared identities rather than emphasizing differences.
Chapter 7: Vaccine Whisperers and Fact-Resistant Humans
- Many people reject facts due to identity protection—they don’t want to change a belief that is tied to their identity.
- Instead of overwhelming them with data, listening and empathizing can help create openness to change.
- He shares stories of “vaccine whisperers” who successfully change minds by approaching skeptics with understanding rather than confrontation.
Part 3: Collective Rethinking – Creating a Learning Organization
This section discusses how organizations and societies can foster rethinking.
Chapter 8: Charged Conversations
- How organizations can promote open-mindedness.
- Psychological safety—where people feel comfortable challenging the status quo without fear of retaliation—is key.
- Companies that encourage curiosity and learning from failure are more innovative.
Chapter 9: Escaping Tunnel Vision
- Many organizations stick to outdated playbooks and fail to rethink their strategies.
- The Kodak example—where the company ignored digital photography despite inventing it—illustrates the dangers of not rethinking.
- Successful leaders encourage experimentation and challenge their own assumptions.
Chapter 10: Rewriting the Textbook
- Education should focus on teaching students how to think, not what to think.
- He encourages fostering lifelong curiosity and skepticism rather than memorization of facts.
Conclusion: Actions for Thinking Again
Grant provides practical strategies for applying these lessons:
- Think like a scientist—test hypotheses instead of defending beliefs.
- Embrace the joy of being wrong—treat mistakes as learning opportunities.
- Encourage open conversations—listen to understand rather than to refute.
- Rethink your networks—surround yourself with people who challenge your views.
- Keep a “challenge network”—a group of people who push you to improve your thinking.
