Scott Adams is a trained hypnotist and master persuader.  He also draws Dilbert.  Throughout the 2016 Presidential Election, Scott wrote regular blog posts describing how each presidential candidate used persuasion techniques while campaigning.  

A trial lawyer's job is to persuade people - whether insurance adjusters or jurors.  This is an interesting blog post by Scott on how be unpersuasive, or what to avoid when trying to persuade.  Anyone interested in persuasion should read this post and the rest of Scott Adam's blog.  Scott might even persuade a few blog readers to buy his book.
