Why is it good to do the exercise?

Do you end up making predictable decisions despite lofty intentions? Many teams find it hard to derive benefit from the group’s joint knowledge in decision-making. Psychology professors Norbert Kerr and Stefan Schulz-Hardt have each shown this in their research surveys. Group discussions are often centered around previously known information. If someone, contrary to expectations, shares information that goes against the common perspective, the group tends to attach less important to this. In addition to an open discussion, groups may therefore need a strategy to incorporate new information.
