About this ebook
The fascinating psychology of blindspots, their complex causes, and the alarming consequences of looking without seeing.
Can we believe our eyes? Most of us are confident that we can, but we shouldn't be so sure. Every day, we fail to see things that are right in front of us, miss sudden or unexpected changes and fall for illusions without realising it. The culprit? Blind spots. These hidden gaps in our perception are responsible for errors in operating machinery, diagnosing medical conditions, giving evidence in court and even influence how we invest our money or shop.
Unseen explores the hidden corners of the human mind where perception fails, from the everyday oversights to the deep-rooted cognitive biases that shape our worldview. Lifting the lid on how our minds shape what we see, neuropsychologist David Lewis and illusionist Keelan Leyser explore the different types of blind spots, why they occur, how they can be used to manipulate our thoughts and the practical steps we can take to avoid them.
