Not everyone chooses products based on their feelings. In fact, I often find it quite difficult to find basic products such as the ones you list because what I want is not available among the popular, advertised brands. Take a heavily advertised staple such as peanut butter for example. How I feel about a brand has zero influence on my selection. And no amount of advertising will change that because there is exactly one brand available in my area which has the combination of features that I want (no-stir, un-sweetened and lightly-salted), so that is the one I buy. I could give examples of other basics like hand soap, toothpaste and paper goods that I choose because competing products failed to meet my needs, not because I "feel good about the brand". "People that think they're immune to advertising are ironically the easiest to influence". I would be interested to know on what you base this claim, and does it differentiate between mere "belief" that one is immune, and the conscious intent to recognize and reject the explicit and implicit messages in advertising.
