Persuasive Technology: Using Computers to Change What We Think and Do.

BJ (yes, that's how he likes to be called) has created an important new discipline: captology -- computers as persuasive technologies. Captology is of vital importance to everyone: the person in the street, the ethicist, the marketing and advertising person, and of course those who build, deploy, and use modern technology. Today's technology is used to change attitudes and behavior. This creates powerful opportunities, multiple challenges, and severe ethical issues. This powerful, yet easy-to-read book addresses the issues critically, with insight, and in depth.
