We all have them. And we know everyone else does, too. But we avoid thinking about them, even though they affect our thinking deeply. What are they?

They are cognitive biases, and they lead our mind to do things that might not be in our best interest. We are all prone to being affected by them, yet hardly anyone takes the time to learn about them—and how to make sure they don’t have as great an impact on us.

That’s where this guidebook comes in, helping teens and adults learn about each bias so that we can make a concerted effort to not fall prey to their powers. Armed with this information, we can think more clearly, better understand ourselves and others, and make good decisions to benefit our lives.

This is powerful information precisely because so few people seek it. Those who read this book will have an advantage over others who are mentally manipulated without knowing it.
