What does it mean when you cocoon knowledge?

Opinions and strategies vary from person to person. Pages 9 through 19 of Infotopia describes this phenomenon. When there is a large group, differing voices can be muffled. Out of fear of meeting opposition, many people with a good idea will keep quiet. This quietness can lead to a cocooning of information. Every person in the group goes along with the same idea; however, the same idea is not always the best idea. This has happened in many organizations and even politics. Individuals, including myself, need to realize that speaking their idea, even if it is dismissed, can be helpful. By stating other opinions, this can promote reconsideration, revision, or complete change in ideas for the better.
