Win Bigly: Persuasion in a World Where Facts Don't Matter is a 2017 nonfiction book by Scott Adams, creator of Dilbert, and author of How To Fail At Everything and Still Win Big. The book presents Adams's theory that Donald Trump's victory in the 2016 United States presidential election was due to Trump being a "master persuader" with a deep understanding of persuasion and the human mind. In 2015, Adams publicly predicted Trump's victory. Adams later cited his research into the field of persuasion as the basis for his claim. He wrote Win Bigly to analyze Trump's tactics and offer guidance to improve readers' communication skills. He describes people who, like Trump, are skilled at convincing listeners as "master persuaders". He posits that when debating an issue, facts are only important when they can impact at an emotional level. Source: Wikipedia (en)
