Michael Pettit reveals how deception came to be something that psychologists not only studied but also employed to establish their authority. They developed a host of tools for making deception more transparent in the courts and elsewhere.

This accessible book provides a foundational understanding of the science of deception and lie detection. Focusing on core issues for the field, it discusses classic and current psychological research into lying as well as theoretical approaches to understanding human lie detection. This book explores engaging questions around how people lie, how people make decisions about believing others, and how we can detect deception. Each chapter is clearly structured to support students of all levels by summarising content, presenting key research, and systematically evaluating findings. Chapters explore topics including some of the most promising current lie detection techniques, how and why people lie, how lying develops in children, and whether unconscious thinking can boost lie detection accuracy. Providing an overview of key issues in deception, this book will be of great interest to students and lecturers in the field of deception and lie detection, as well as anyone generally interested in this fascinating field of research.

Well-heeled American corporations have long had a financial stake in undermining scientific consensus and manufacturing uncertainty. In The Triumph of Doubt, former Obama and Clinton official David Michaels details how corrupt science becomes public policy -- and where it's happening today. Opioids. Concussions. Obesity. Climate Change. America is a country of everyday crises -- big, long-spanning problems that persist despite their toll on the country's health. And for every case of government inaction on one of these issues, there is a set of familiar, doubtful refrains: The science is unclear. The data are inconclusive. Regulation is unjustified. It's a slippery slope. Is it? The Triumph of Doubt traces the ascendance of science-for-hire in American life and government, from its origins in the tobacco industry in the 1950s to its current manifestations across government, public policy, and even professional sports. Amid fraught conversations of "alternative facts" and "truth decay," The Triumph of Doubt wields its unprecedented access to shine a light on the machinations and scope of manipulated science in American society. It is an urgent, revelatory work, one that promises to reorient conversations around science and the public good for the foreseeable future.
