Erikson chose the title of his book deliberately, and the argument it makes is exactly the reverse of what the title suggests. The book is not a guide to diagnosing and dismissing the idiots around you. It is a case for why the idiots do not exist. Every time someone frustrates you by being too slow, too detailed, too impulsive, or too aggressive, they are probably operating from their natural style in a context where it does not match yours. They are not broken. They are different. And the frustration you feel is the gap between their style and your expectations, not evidence of their inadequacy. Erikson's concluding argument is that the most valuable communication skill available to any person is genuine curiosity about others: the desire to understand how someone else processes the world, rather than assuming they process it like you and finding them deficient when they do not. This is harder than it sounds. Our own style feels natural and correct. Other styles feel unnecessary, irrational, or time-wasting. It takes real discipline to approach someone genuinely different from you with the attitude that their difference is information rather than a flaw. The payoff is significant. People who understand and adapt to different communication styles are better leaders, better collaborators, better partners, and better negotiators. They do not spend energy being frustrated by people who are not like them. They spend it understanding and working with the full range of human difference around them.
