Brainjacking takes us on a journey through advertising and marketing's attempts to understand and influence our thoughts and desires, from the earliest billboards to the technologies of the future. To discover how science intersects with our desires and decisions, the book pulls together three strands that have a huge impact on our lives: advertising, how much privacy we can and should have in the new electronic world, and how to draw the line between information and influence. With Brian Clegg as your guide, this is a book that will help you unpick the insidious world of brainjacking. Expertly pulling together different strands on disparate topics including AI, Big Data, subliminal advertising and more, this essential investigation shows how new and old technology and science can be combined to influence human behaviour and beliefs.
