"Behavioral decision research is a hot field, and Hayward does a great job of applying one of the most important errors that we make, overconfidence, to a wide range of important executive decisions. Reading this book may be key to stopping you from making an irreversible decision that could destroy your organization."

"Ego Check explores one of the core leadership issues facing firms today. Just why is it that leaders so often get derailed by their own hubris? Hayward’s book illustrates this phenomenon, gets at its roots, and provides a set of interrelated ideas on overcoming this pervasive pathology. Ego Check is a wonderful mix of research, theory, examples, and applications. Well done."

"Self confidence is a vital component to achieving success in life and in business. Yet, the trap of overconfidence often leads to hubris, which has destroyed lives, businesses, and countries. Mathew Hayward explains why this occurs and, more important, how to avoid its tragic pitfalls. Ego Check offers positive and enlightening insights for executives and leaders of any organization."
