5. Think Again – Adam Grant

Master the art of rethinking and unlearning.

We often cling to our beliefs, even when new evidence suggests we might be wrong. Think Again challenges you to embrace the power of reconsideration. Adam Grant shows that mental flexibility—the ability to unlearn outdated ideas and adapt to new ones—is just as important as intelligence. Through compelling examples, he encourages readers to develop the courage to say, “I was wrong”, and the wisdom to embrace new perspectives.

Key Takeaway: Your beliefs should evolve as new information emerges. Staying open-minded is a superpower.

6. Thinking, Fast and Slow – Daniel Kahneman

Understand the two systems that drive your thinking.

This groundbreaking book by Nobel Prize-winning psychologist Daniel Kahneman introduces the concept of two thinking systems:

• System 1 (Fast Thinking): Intuitive, automatic, and emotional. Used for quick decisions but prone to errors.

• System 2 (Slow Thinking): Analytical, effortful, and logical. Used for deep reasoning but requires focus.

By understanding how these systems interact, you can recognize when to trust your intuition and when to slow down and think critically.

Key Takeaway: Your brain operates on two levels—learning when to rely on intuition and when to engage in deep thinking is key to sound decision-making.

7. The Intelligence Trap – David Robson

Why smart people make dumb mistakes—and how to avoid them.

Have you ever wondered why some of the most intelligent individuals make shockingly poor decisions? David Robson explores this paradox in The Intelligence Trap. He reveals that intelligence alone isn’t enough; without critical thinking, even the brightest minds can fall victim to biases and overconfidence. This book is an eye-opener for anyone who believes intelligence guarantees good judgment.

Key Takeaway: True wisdom comes from intellectual humility—constantly questioning your own assumptions and seeking diverse perspectives.

In a world filled with misinformation, biases, and emotional decision-making, mastering critical thinking is no longer optional—it’s essential. The books on this list offer powerful insights and practical techniques to help you analyse situations, challenge assumptions, and make better choices in all areas of life.
