How to Know a Person

Every person is building their own version of reality, moment by moment, and that changes what it means to understand them. It’s not about collecting facts on someone’s background; it’s about asking how they perceive their situation—what it’s like to be them right now. Brooks calls the people who can do this Illuminators, and the people who can’t Diminishers. Diminishers make others feel small, usually because they’re trapped in their own heads: too self-centered, too anxious, too sure everyone sees the world as they do. They fall into the Lesser-Minds Problem—because you know all of your own thoughts but only a sliver of anyone else’s, you quietly assume you’re more complex than the people around you. Illuminators reverse that. The Bell Labs researcher Harry Nyquist made his colleagues measurably more productive not through brilliance but because he really listened to their challenges, got inside their heads, asked good questions, and drew out their best.
