Derren Brown (
wiki bio) is an expert in
NLP and other manipulative techniques and uses them as an entertainer in the UK.
This following video (~7mins) is from a show glorifying him, so take it with a fair amount of salt if you would like to comfort yourself with it, but to anyone moderately interested in psychology, it shouldn't be surprising.
Subliminal Advertising
To me, I think that we as individuals are exposed to this unconscious manipulation almost every waking second of our lives not just when we're conscious of our exposure (lets skip the memory-organising aspect of sleep which doubtless reinforces the messages).
We need to carefully select the propaganda we want to expose ourselves to and attempt to rebalance the propaganda that we are conscious of our exposure to.
Question everything.
Read and watch nakedly propagandist material from sources which are in opposition to those you are aware of your exposure to.
Stop believing in absolutes.
Before you buy or buy into anything, question even your own motives.
I think living in a country without understanding the language at all can give you some clear breathing space after some time, too. (i've done this - by accident, not design - for most of my adult life)
Sounds taxing, but there's a lot of effort that goes into our manipulation, so it stands to reason that there's no quick fix to it.
(Just because you're paranoid, doesn't mean they're not after you. *bites nails down to wrist*)
