What is Cognitive Diversity?
The presence of different thinking styles, problem-solving approaches, and cognitive frameworks within a team, distinct from demographic diversity, though often correlated with it. Cognitive diversity is what makes a team collectively smarter than its smartest individual member.

In practice
The easiest way to reduce cognitive diversity is to hire in your own image. The harder and more valuable path: actively seek people who challenge your framing, disagree constructively, and approach problems from entirely different disciplines. Cognitive friction, handled well, is a feature.
