Second that emotion

the long version

"Traces the fascinating process whereby a passion for an idea, a politician a celebrity, or a brand gives rise to a set of illogical beliefs that becomes the basis for a powerful movement. Conventional wisdom has it that spin doctors and Madison Avenue are responsible for manipulating our thoughts, causing us to endorse ideas, people, or products that we would otherwise reject. But Holden shows that while advertising and propaganda can provide a park and social media can provide the kindling, individuals create consumer, political, and cultural trends based more often than not, on thought processes that they know logically are flawed." -- Book jacket.
