Why the smartest teams make the worst decisions — and how to fix the rooms they decide in.

When organisations underperform, the diagnosis usually points to execution. Post-mortems are commissioned. Consultants are hired. Teams are restructured. Sometimes that's right. But there's another gap, earlier and harder to see — the one that opens in the room where the decision was made.

Drawing on years of work with executives, humanitarian leaders, and policymakers globally, Valerie Won Lee shows how the very act of gathering smart people in a room activates seven forces — social, psychological, political — that can quietly degrade the outcome.

Maybe you recognise one in your own meetings. The Driver who pushes the room to closure before the real questions surface. The Challenger whose objection is technically welcomed and quietly ignored. The Systems Thinker treated as an obstruction whenever they ask what happens downstream. These forces are not random. They are predictable. And once you can see them, you can do something about them.

Decision Shapers gives you the language, the diagnostic, and the interventions: the Seven Forces framework, the Decision Distribution Map, the five failure patterns that recur across every sector, and the role of the Decision Architect — the person who designs the process before the meeting, reads the forces in the room, and changes what happens next.

The next meeting on your calendar is the one that counts.
