Optimally Irrational: The Good Reasons We Behave the Way We Do provides economists, social scientists and researchers in behavioral economics with a clear view of the frontier of research in economics and other behavioral sciences, including how the different biases unveiled by behavioral economics make sense when we try to optimize problems. The book evaluates the role of bias in human economic behavior, considers the human decision-making processes as the product of natural selection, and explores why we behave the way we do.
