What is Critical Thinking?

Have you ever made a decision you later regretted? Trusted someone who turned out to be lying? Believed something that wasn’t true—or missed something important that was right in front of you?

You’re not alone. We all make mistakes. But many of them could have been avoided if we had just stopped to think a little more critically.

That’s what this book is about.

It’s about learning how to think in a way that helps you make better decisions, avoid common traps, and see through the tricks people might use to influence you.

Inside this book, you’ll meet people who made life-changing choices—like a man who looked through a telescope and transformed our understanding of the universe, or someone whose quick thinking during a vacation helped avert disaster.

You'll also see how smart, experienced people—judges, politicians, experts—sometimes make serious errors when they fail to think critically. And you'll learn how to spot the tactics advertisers, scammers, and even well-meaning friends use to sway your beliefs.

Critical thinking isn’t just for school or work—it’s for life. Every day, you’re bombarded with claims, arguments, and information. People want you to buy things, believe things, do things. So how do you decide what to trust?

This book will give you the tools to figure that out for yourself.

The world doesn’t need more people who can deceive others. It needs more people who can think clearly.
