We'd like to think otherwise, but most human behavior follows a predictable path. Actions (aka stimulus from the outside world) lead to predictable reactions on our part.

Learn how to use desire lines, and commitment, reinforcement, and breakage techniques to influence behavior patterns, in this installment of Chris Nodder's Persuasive UX series.
