Bias is a disproportionate weight in favor of or against an idea or thing, usually in a way that is closed-minded, prejudicial, or unfair. Biases can be innate or learned. People may develop biases for or against an individual, a group, or a belief. In science and engineering, a bias is a systematic error.

This book reveals how our minds are tripped up by error and prejudice (even when we think we are being logical)

The aim of Biases is to explain the science in plain enough language to help well-intentioned people achieve that alignment. By gaining awareness, we can adapt beliefs and behavior and "outsmart the machine" in our heads so we can be fairer to those around us. Venturing into this book is an invitation to understand our own minds.
