<p>During class discussions, about what percentage of comments are said out of a genuine need for that comment to be made (meaning the said contributors truly believed what they were saying and felt the need to defend it) vs. comments made just for self-aggrandizement (to bring up a new insight which the contributor doesn’t really believe in or has no genuine opinion about… simply to impress others and to appear insightful)? I realize that the two options are not mutually exclusive, but think more in terms of the contributor’s intent in saying a particular comment (in other words: to which purpose is this intent closer?)</p>
