YES! 50 SCIENTIFICALLY PROVEN WAYS TO BE PERSUASIVE‘, June 10th 2008, here is the new book from Dr.Cialdini about influence.

Based on over sixty years of research and many fascinating new studies, several of which were conducted by them, the authors introduce simple but remarkably powerful techniques for moving people in your direction. In addition to introducing a variety of effective persuasion strategies, they also discuss the types of things to watch out for to help you resist both subtle and overt influences on your decision making

It’s already available for pre-order on Amazon.

If you don’t know Cialdini, I suggest his well known book Influence – The Psychology of Persuasion (available also in Italian in a good translation).
