Cognitive diversity is just a fancy way of saying we think differently, we problem solve differently, and we see the world differently. In Enneagram terms, it means you've got more than one leadership style type in the room. You've got a big picture Challenger, your creative idea generator, your detail-obsessed Reformer, your loyal Skeptic who catches risks before they blow up, and You're a peacemaker who keeps the whole thing from exploding. Now, does that make meetings more fun? Not necessarily. But does it make your products, decisions, and results better? Every single time.
