 This sort of view works well with influences like subliminal advertising. But it would also appear to apply to other sorts of psychological influences that bypass conscious attention, such as priming effects and the decision-making biases and other processes that involve unconscious, fast processing made famous by the work of Daniel Kahneman, Amos Tversky, and colleagues (see Kahneman 2013 for an overview). However, it faces obstacles in dealing with other clear cases of manipulation. Many manipulative influences, such as peer pressure, nagging, emotional appeals, guilt trips, do not appear to be hidden influences. Indeed, it is difficult not to be aware of an attempted influence when that influence takes the form of nagging, peer pressure, or a guilt trip.
