This great short talk by Dan Ariely who wrote Predictably Irrational, gives us a different perspective on how our warming up process, if left as an unconscious and unaware process, is so susceptible to influence to the extant we can question our ideas about how in control we are of our decisions.
What a piece of work is a man! How noble in reason! how infinite in faculties! in form and moving
how express and admirable! In action how like an Angel In apprehension how like a god!
The Tragedy of Hamlet, Prince of Denmark (Act II, Scene ii, 285-300)
