Unseen: Blind spots and why we miss what matters most

The first book to explain the psychology and neuroscience behind looking without seeing and seeing without looking, it describes how:

  • Sights that should have received urgent attention are overlooked, and others are misinterpreted.
  • Six different blindspots can occur, from failing to see what is there to seeing what is not there.
  • Digital technology and AI are changing our lives forever. As society becomes ever more complex, blindspots increase exponentially, with consequences ranging from embarrassment to catastrophe.
  • For psychological reasons, it is far easier to eliminate machine-made mistakes than human error.
  • Individuals, companies, organisations, and governments increasingly recognise how blindspots play a crucial role in personal success, military operations, medicine, marketing, retailing and political campaigning.

This 65,000-word book is based on original research conducted by the first author’s laboratory in the Science Park at the University of Sussex, the second author’s practical experience as one of America’s most successful digital magicians, and over 500 peer-reviewed academic papers. 

Filled with fascinating examples and practical suggestions, the book provides strategies by which readers can avoid mistakes due to blindspots and safeguard themselves against their exploitation by others.

  • "  Lewis and Leyser show how subliminal priming influences the ways humans encounter the world, and provide commonsense strategies to avoid falling prey to such illusions and oversights. It's a riveting and relevant work of pop psychology. "
