The Belief Instinct: The Psychology of Souls, Destiny, and the Meaning of Life

"A balanced and considered approach to this often inflammatory topic." ―Nature

Lively and brilliantly argued, The Belief Instinct explains the psychology behind belief. Drawing on surprising new studies as well as on literature, philosophy, and even pop culture, The Belief Instinct will reward readers with an enlightened understanding of belief―as well as the tools to break free of it.

I personally recommend this book as a way to be aware of your own cognitive biases and be aware of how humans create beliefs. I think knowledge of these principles can help you understand why nutrition is such a complicated field - a lot of it is based on faith.
