Got a source on that? My experience and the research disagree, these take advantage of lower level cognitive biases that are prevalent (or maybe universal) in human beings.
Lots of people have even a habit of identifying such tricks. Others, like me, have an automated tendency to map them to the list of cognitive biases from Wikipedia - http://en.wikipedia.org/wiki/List_of_cognitive_biases - the thing that deserves to be printed and framed.
I certainly have that same tendency, and have fun playing the "name that bias" game.
But we are both in a tiny minority and are still influenced by those biases even when we recognize them. I would argue we would be less influenced when we recognize them but that's conjecture on my part.
