Animation describing the Universal Principles of Persuasion based on the research of Dr. Robert Cialdini, Professor Emeritus of Psychology and Marketing, Arizona State University.
Dr. Robert Cialdini & Steve Martin are co-authors (together with Dr. Noah Goldstein) of the New York Times, Wall Street Journal and Business Week International Bestseller Yes! 50 Scientifically Proven Ways to be Persuasive.
You may not be able to persuade everyone all the time but science helps us understand how to persuade everyone some of the time and some one all of the time.
Of course, will simply knowing these things change the art of persuasion? Research says no.
So. remember these when dealing with a denialist and see if any work.
