9 Books That Will Improve Your Thinking and Decision Making
-
Thinking, Fast and Slow
Daniel Kahneman’s classic breaks down two modes of thought: fast, instinctive thinking and slow, deliberate reasoning. Reading it helps you spot when your quick judgments mislead you and how to slow down when it matters most. I strongly recommend this as a starting point if you want to build solid critical thinking and better decision making.

Predictably Irrational
Dan Ariely shows how people often make illogical choices in predictable patterns. The book hosts real-life experiments that reveal why we overpay, procrastinate, or overvalue things, and how to design better choices for ourselves and others.

Nudge
Richard Thaler and Cass Sunstein explore how small design tweaks—nudges—can steer behavior for good, without restricting freedom. It’s a practical guide to decision architecture for personal, workplace, and public contexts.
-
The Power of Habit
Charles Duhigg digs into how habits form, how to break bad ones, and how to replace them with routines that support smarter decisions. A must-read for building consistency in thinking and action.

Decisive
Chip Heath and Dan Heath offer a four-step framework to avoid common decision traps: widen options, reality-test assumptions, attain distance, and prepare to be wrong. It’s straightforward and actionable for everyday choices and big bets alike.

Rolf Dobelli collects short, digestible chapters on cognitive biases. It’s a handy reference you can skim during lunch or before meetings to catch faulty reasoning in real time.
