Bottom-up influence is odd. When you sit next to a briefcase and act more greedy than you usually would, it is as if your executive brain centers are nodding in agreement to hidden advisers whispering in your ear. It seems mysterious and creepy because it’s so clandestine. Those who seek to influence you are sensitive to this, and try to avoid creating in you the uncomfortable realization that you have been duped. Priming works only if you aren’t aware of it, and those who depend on priming to put food on the table work very hard to keep their influence hidden.
