Tene and Polonetsky expounded a Theory of Creepy in 2013. Dr Leiser’s book shows today how well beyond creepy and even overshooting downright sneaky many digital services are by design today. His book lays out in stark terms the real harms, including of financial loss and a dangerous erosion of trust and autonomy, that ensue from the digital manipulation to which we are daily subject. Children and more vulnerable internet users are the most adversely affected. Dr Leiser’s text is a timely and accessible illumination of the issue of deceptive design in digital services that provides up-to-date and expanded language to describe the range of “dark patterns” phenomena we sometimes can’t see but experience. He carefully illustrates the challenges globally these issues present for enforcement as they cut through and sometimes find gaps in consumer, data protection, privacy and sectoral laws. The book thoughtfully proposes realistic and layered solutions which are all the more urgent given the now turbocharging effects of AI. This book is a very important opportunity to act and change course and to do so right now.
