“There is always the danger that those who think alike should gravitate together into ‘coteries’ where they will henceforth encounter opposition only in the emasculated form of rumor that the outsiders say thus and thus. The absent are easily refuted, complacent dogmatism thrives, and differences of opinion are embittered by group hostility. Each group hears not the best, but the worst, that the other groups can say.”

“The author challenges how much sanctity has to do with sameness, as he says saints are as different from each other as those in any group -- even murderers.”

“A man has as many social selves as there are distinct groups of persons about whose opinion he cares. He generally shows a different side of himself to each of these different groups.”

“Majority decisions tend to be made without engaging the systematic thought and critical thinking skills of the individuals in the group. Given the force of the group's normative power to shape the opinions of the followers who conform without thinking things through, they are often taken at face value. The persistent minority forces the others to process the relevant information more mindfully. Research shows that the deciscions of a group as a whole are more thoughtful and creative when there is minority dissent than when it is absent.”

“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.”

“Groups are grammatical fictions; only individuals exist, and each individual is different.”
