As we get older, do we become less impressionable?
Recent exploration of TV programs shows a new line of Reality Television, teams of people (professionals) working together to some goal. I've recently seen "Design Challenge", "Project Runway", "Shear Genius". In these shows are strangely familiar characters in different circumstances. The entertainment factor for me comes from watching these different people cope with the group dynamics, and in being able to predict who won't get through to the next round. In fact, I'm getting pretty good at predicting.
Perhaps the reason for the popularity of reality television is that lingering childhood "need"* to learn behavior by observation.
(*need = latent instinct for imprinting...is it ever entirely surpressed?)
