Persuasion Diagram, visual review of Dr. Robert Cialdini’s work

If you want to sell or buy anything, you must get to know this man’s work.  He is the most cited author­ity on the sci­ence of influ­ence and per­sua­sion, and he has a very strong eth­i­cal com­po­nent to his work. With such under­stand­ing of how to influ­ence a buyer it is wise that he should! Plus he knows things about Tup­per­ware par­ties that no-​​one else does ;-)
