Tin foil hat time: I've started writing down companies behind ads that happen to slip through my defenses that are obnoxious/offensive/etc. Because, as you mention, so much of advertising is psychological manipulation. It'll be helpful to have a list of offenders to reference to before making a purchase for example.

The idea occurred to me after someone here proclaimed that they're simply unaffected by ads, reasoning they don't make rash purchases. Someone naturally countered with the extreme subconscious effect of ads.

This list thing is imperfect (I mean look how omnipresent car logos are for example) but it's an improvement from thinking you're immune to ads. Memory is fickle, and why Memento is my favorite movie.
