“The fatal misconception behind brainstorming is that there is a particular script we should all follow in group interactions.... [W]hen the composition of the group is right—enough people with different perspectives running into one another in unpredictable ways—the group dynamic will take care of itself. All these errant discussions add up. In fact, they may even be the most essential part of the creative process. Although such conversations will occasionally be unpleasant—not everyone is always in the mood for small talk or criticism—that doesn’t mean that they can be avoided. The most creative spaces are those which hurl us together. It is the human friction that makes the sparks.”

“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.”

“The only way to maximize group creativity—to make the whole more than the sum of its parts—is to encourage a candid discussion of mistakes. In part, this is because the acceptance of error reduces cost. When you believe your flaws will be quickly corrected by the group, you're less worried about perfecting your contribution, which leads to a more candid conversation. We can only get it right when we talk about what we got wrong.”

“It is not many things that modern psychology agress upon, but all the different approaches of psychology agrees on one thing: that people in groups become more stupid. Individually people are more intelligent, because they have to take their own responsibility, but in a group they do not have to take the same responsibility. The two basic power strategies to try to manipulate and gain control over another person are: silencing and attacking. Silencing means to not listen to, to exclude or ignore and not respect a person. Attack can both mean to attack a person directly or to try to discredit a person through lies, to ridicule a person or by spreading malicious rumours. All organizations are more or less dysfunctional. In a dysfunctional group, the members of the group play three different roles: agressor, denier and victim. The agressor is the role that attack and ridicule people, the denier never knows what is going on, there is “no body at home”, and the victim is the resultat of these two roles. It is always easier to follow a group without awareness, than to follow your own heart, to trust your own intelligence, love, truth, silence and creativity.”

“Human kindness can be found in all groups, even those which as a whole it would be easy to condemn.”

“We must remember that one determined person can make a significant difference, and that a small group of determined people can change the course of history.”
