“None of us is as dumb as all of us. It means that when you get a group of people together to make a critical decision, groupthink can set in. There's all this technical information, a critical decision needs to be made, and everyone starts marching in the same direction. There might be some people who think it's the wrong decision, but they don't say anything. They just remain a part of the group. We've learned that groups can make stupid decisions that no single individual in the group would make.”
