The market is the master of the psychology, not visa versa, IMHO, meanwhile the manipulation of markets and surrounding data/information are at an all time high, wouldn't the manipulation of psychology be integral?  Reminds me of the business/marketing model of "managing perceptions" to create value or destroy value.

It is hard to identify it, let alone, wrench yourself away from the herding instinct and which is used constantly in the business of managing perceptions and markets.
