Reflecting upon James SuroWiecki book on Wisdom of Crowds, it's captivating to see how group can turn out to be smart or dumber. I like this paragraph of his writing especially
"... the truth is that, especially when it comes to problems when there is no right or wrong answer, there's no guarantee that the most-informed speaker will also be the most influential. On juries for instance, two-thirds of all foremen - who lead and structure deliberations - are men, and during deliberations men talk far more than women do, even though no one has ever suggested that men as a gender have better insight into questions of guilt and innocence. In groups where the members know each other, status tends to shape speaking patterns, with higher-status people talking more and more often than lower-status people. Again, this wouldn't matter as much if the authority of higher-status people was derived from their greater knowledge. But oftentimes it doesn't. Even when higher-status people don't really know what they are talking about, they're more likely to speak. A series of experiments with military fliers who were asked to solve a logic problem, for instance, found that pilots were far more likely to speak convincingly in defense of their solutions than navigators were, even when the pilots were wrong and the navigators were right."
Someone is not always smarter than everyone in all instances. When there's a working group or team, allow others to speak at equal levels. While this is almost common practice in our era, group decisions can still go both ways - smarter or dumber.
Generally, groups get dumber in cases of information cascade, whereby ideas, solutions or discussions are built on top of the other in one direction. Some people do this to maintain harmony within the group, give in to higher authority, come to common consensus, achieve group buy-in, or simply because they are short of ideas themselves. While this may be good in certain ways, it sure compromises the quality of the decisions.
A group makes good decisions when it is diverse and its members independent. In simple terms, its best when everyone in the group gathers their own information (either from existing or external) and are allowed to contribute without affecting or being affected by another's information. There are some simple steps to make this happen, I'd like to call this the Group Smart method:
- Identify participants who are likely to have individual information or knowledge of the problem. Invite them to a meeting
- Allow the participants some time after the problem is presented to gather their own thoughts and information individually. Present the problem before the meeting if it requires significant time to prepare or take it offline if a complex problem is surfaced during a meeting. The idea is to give each member enough time to prepare his information.
- A facilitator must be present to ensure that the problem can be further elaborated without allowing participants' thought to affect each other.
- After each participant is satisfied with his information, the facilitator can then collect the information from each participant individually.
- Upon collecting all information, the facilitator reads out all information in random fashion and allows the group to contest each other. Each participant may attempt to guess who contributed the information, but the luxury of 'supposedly I don't know who it's from' mentality will allow each piece of information to be contested fairly.
- While the group is having the discussion, the facilitator needs to ensure that all participants have the chance to speak up. The facilitator also has to pick up constructive comments that would steer the group's judgment.
- A summary on the trail of decision-making is presented at the end of the discussion. The facilitator will highlight any information that has not been included in the decision making process.
- The group can agree on the outcome of the decision or iterate the process of argument based on new information.
