To me the bothersome things are the expansion of the proportional impact of individual influencers and also the shrinking of the number of channels required to deliver influence effectively. In the lunchroom example, so long as lots of other folks are putting posters on the wall, and presumably some kids don't look at the lunchroom posters, I don't have a problem with either the college or the military changing behavior that way. There were many alternatives, and the poster wasn't forced on anyone. The influence we're seeing now is expensive (much higher proportional impact if you can pay), and effectively guaranteed (everyone is tuned to the same channel or two). I hope we don't have to analyze individual interventions, I'd much rather just break up the channels, or increase the diversity of the programming. Mostly because I'm not sure how to (and I'm not sure we should) answer your question.
