“Because elites are informal does not mean they are invisible. At any small group meeting anyone with a sharp eye and an acute ear can tell who is influencing whom. The member of a friendship group will relate more to each other than to other people. They listen more attentively and interrupt less. They repeat each other's points and give in amiably. The 'outs' they tend to ignore or grapple with. The 'outs' approval is not necessary for making a decision; however it is necessary for the 'outs' to stay on good terms with the 'ins'. Of course, the lines are not as sharp as I have drawn them. They are nuances of interaction,not prewritten scripts. But they are discernible, and they do have their effect. Once one knows with whom it is important to check before a decision is made, and whose approval is the stamp of acceptance, one knows who is running things.”
