“The principle of independent judgments (and decorrelated errors) has immediate applications for the conduct of meetings (…).
A simple rule can help: before an issue is discussed, all members of the committee should be asked to write a very brief summary of their position. This procedure makes good use of the value of the diversity of knowledge and opinion in the group. The standard practice of open discussion gives too much weight to the opinions of those who speak early and assertively, causing others to line up behind them.”
Group meetings can be a challenge. Especially if certain members of the team tend to have more difficulty to verbally explain points of view. If you can't voice it, write it down before the meeting. It’s homework, but it’s important. Being good at disagreeing is crucial in everything, not only in a company.
