1. Diversity of thinking beats individual brilliance.
A team of smart people who think alike can perform worse than a team with varied perspectives.

Success in complex problems comes from combining different viewpoints.
3. The "clone fallacy" is dangerous.
A group of talented individuals does not automatically become a talented team.

Humans naturally prefer people who are similar to themselves, creating blind spots.

We struggle to see the limitations of our own viewpoint.

Diverse teams solve complex problems more effectively.

Shared assumptions prevented analysts from recognizing key threats.
