A group is definitely able to be influenced by one single individual, especially when the group is either apprehensive and undecided or if the issue is irrelevant and their attitude is slightly indifferent. It is centrally decided on power, and the individuals ability to exercise their power effectively upon the larger group. The same can occur in opposite roles, I think this is more common but both are powerful and drastically persuasive. The issues range from life changing political influences to petty decisions made by a coach, when a strong figure is presenting ideas with a meaningful approach and strongly supported evidence the group is almost unable to oppose it or question the proposal. Wright was influenced by the "communist" groups and they too were influenced by Wright's attitude and ideas.
