Geoffrey Beattie is Professor of Psychology at Edge Hill University and Visiting Scholar at the University of Oxford, UK. He is a prize-winning psychologist, author, and broadcaster with a PhD in Psychology from the University of Cambridge. He was awarded the Spearman Medal by the British Psychological Society for ‘published psychological research of outstanding merit.’

"Lies, conspiracy theories, and deceptions have become so diffuse that they now constitute a kind of general discourse, perpetrated through social media, but also present in everyday interactions. While mendacity is an innate trait of humans, the reasons why it has become so prominent remains obscure, until one reads Geoff Beattie’s brilliant synopsis, which reads at times like a novel, at others like a psychological-semiotic treatise, reflecting Geoff’s inimitable style. This is truly a must read for everyone, given that we are on the threshold of an even greater danger—AI and deepfake technologies. This book is both an in-depth analysis of human lying and a basis for insulating oneself from the inevitable future."Marcel Danesi, Professor Emeritus, University of Toronto, Canada.
