Think Again: The Power of Knowing What You Don’t Know

Adam Grant

The ability to rethink may be your most valuable skill.

In Think Again, organizational psychologist Adam Grant challenges the idea that intelligence is about having the right answers. Instead, he argues that real progress comes from knowing when to question our assumptions, update our beliefs, and change our minds.

Blending research with engaging real-life stories, Grant explores why people cling to outdated ideas — even when evidence suggests otherwise — and how this resistance to rethinking holds us back at work, in relationships, and in society. He introduces practical ways to develop intellectual humility, curiosity, and openness to learning.

Rather than focusing only on learning new information, Think Again emphasizes the importance of unlearning — letting go of beliefs that no longer serve us — and relearning in a rapidly changing world. The book shows how to create environments where healthy disagreement, critical thinking, and growth are encouraged.

Insightful and hopeful, Think Again helps readers build the mental flexibility needed to make better decisions, collaborate more effectively, and adapt with confidence.

Because growth doesn’t come from being right — it comes from being willing to rethink.
