Surrounded by Idiots: The Four Types of Human Behavior and How to Effectively Communicate with Each in Business (and in Life)

More about the book

Erikson explains that there are four key behavior types that define how we interact with and perceive the people around us. Reds are dominant and commanding, Yellows are social and optimistic, Greens are laid back and friendly, and Blues are analytical and precise. Understanding someone's pattern of behavior is the key to successful communication. Erikson provides practical advice for interacting with people based on their color profiles. -- adapted from jacket
