One of the themes you come across again and again in public policy debates about privacy, advertising, marketing, or even free speech battles, is the notion that the public at large is made up of mindless sheep being duped at every turn. And, as Berin Szoka and I noted in our paper "What Unites Advocates of Speech Controls & Privacy Regulation?" if you buy into the argument that consumers are basically that stupid then it logically follows that people cannot be trusted or left to their own devices. Thus, government must intervene and establish a baseline "community standard" on behalf of the entire citizenry to tell them what's best for them.
But there are good reasons to question the premise that consumers are blind to efforts to persuade or influence them -- regardless of what type of media content or communications efforts we are talking about. I was recently reading Communication Power by Manuel Castells and liked what he had to say about how so many media critics make this false assumption. Castells rightly notes:
Interestingly enough, critical theorists of communication often espouse [a] one-sided view of the communications process. By assuming the notion of a helpless audience manipulated by corporate media, they place the source of social alienation in the realm of consumerist mass communication. And yet, a well-established stream of research, particularly in the psychology of communications, shows the capacity of people to modify the signified of the messages they receive by interpreting them according to their own cultural frames, and by mixing the messages from one particular source with their variegated range of communicative practices.
