You are a rational, logical being who sees the world as it really is. THE TRUTH: You are as deluded as the rest of us, but that’s OK, it keeps you sane.
The three main subjects in this book are cognitive biases, heuristics, and logical fallacies. These are components of your mind, like organs in your body, which under the best conditions serve you well.
Life, unfortunately, isn’t always lived under the best conditions. Their predictability and dependability have kept confidence men, magicians, advertisers, psychics, and peddlers of all manner of pseudoscientific remedies in business for centuries.
Cognitive biases are predicable patterns of thought and behavior that lead you to draw incorrect conclusions.
