3. Individual domination:
Quite often, discussions in a group are dominated by a few members.
Although a group discussion means a collective discussion, some people usually manage to usurp a position of informal leadership owing to their personality or style of participation.
This position can also be because of the position held within the organization or simply because of self-confidence generated by previous experiences. Sometimes only a few individuals dominate and the others fade away in a group, thereby defeating the very purpose of group discussion.
