Thanks to certain symptoms, it is possible to understand that a group is closed to different views and away from alternative decisions because of excessive harmony.

• If group members suppose that their decisions are perfect and insist on it,

• If managers are not informed about the arguments supporting the opposing view,

• If group members give more importance to the data supporting their own views and ignore the others,

• If no one tries to consider alternative options,

• If members that do not share the majority’s opinion are excluded,

If symptoms above are to be seen in decision mechanisms of an organization, we can argue that decisions are not made in a healthy way.
