Advertising
If you don't see any manipulation at all in advertising, you may be most vulnerable to it.
I wouldn't know. I can't remember the last thing I bought because I saw it in an ad. I don't read ads in the paper, and I don't watch network TV except for a few things I've Tivoed, and the ads get skipped.
I have a subscription to Consumer Reports online, and when I'm looking for an item, will check that out.
I have never heard anybody comment on the tragedy of the mindless brainwashed millions who included themselves in the mix. Remember, not all brainwashing is designed to sell you snack foods.
