Thinking fast and slow by Daniel Kahneman
A tour de force of cognitive behaviors all mapped to how we take shortcuts and the cost when we don't. The book is pretty full on, moving at a quick pace. There are so many bias' that it can feel like it never ends but they are all insightful and a story for each is given to make them easy to consume. By the end of the book you'll have a clear understanding of when our brains like to take shortcuts and why that this isn't always ideal.
