Dr. Cialdini wrote the best book on the science of persuasion. I had read Influence several times and used to it to build businesses and help hundreds of clients, so it was a great honor to meet and interview him in 2007.
A few years later, I heard he has a new book called "Yes!: 50 Scientifically Proven Ways to Be Persuasive" so I contacted Dr. Cialdini and arranged for several leading influence teacher to interview him.
All this was posted on a blog site that is since gone. I'm posting what's left... a second interview I did at that time.
