Cultural imprinting is the mechanism whereby an ad, rather than trying to change our minds individually, instead changes the landscape of cultural meanings — which in turn changes how we are perceived by others when we use a product. Whether you drink Corona or Heineken or Budweiser "says" something about you. But you aren't in control of that message; it just sits there, out in the world, having been imprinted on the broader culture by an ad campaign.
This is an important read as we start producing our agitprop. There's a lot to think about as we try producing messages that will actually break through to the masses.
It's an interesting theory and dovetails with the fact that advertisements tend not to work as well on autistic people. We tend not to be as big on social conformity, so of course ads that rely on social conformity would be less effective on us.
