Lie Detectors

The polygraph, most commonly known as the lie detector, was created and refined by academics in university settings with support from a few early police agencies. This work is a history of the machine, from the experimental work of the late 1800s that led directly to its creation, until the present. It covers early lie detectors and their inventors from the 1860s to the early 1920s, their use by the police and other law enforcement agencies in the 1930s and their use in Cold War America in the 1940s and 1950s. It then discusses the government's use of the polygraph in the 1960s, the PSE, a new take on the old polygraph, and private businesses' reliance on the polygraph in the 1970s and the government's increasing reluctance to use it in the 1980s. A chapter on new ideas and uses for the polygraph in the 1990s and after concludes the book.

In this fascinating history of the lie detector, Ken Alder exposes some persistent truths about our culture: why we long to know the secret thoughts of our fellow citizens; why we believe in popular science; and why we embrace ?truthiness.? For centuries people searched in vain for a way to unmask liars, seeking clues in the body?s outward signs: in blushing cheeks and shifty eyes. Not until the 1920s did a cop with a PhD team up with an entrepreneurial high school student and claim to have invented a foolproof machine capable of peering directly into the human heart. Scientists repudiated the technique, and judges banned its results from criminal trials, but in a few years their polygraph had transformed police work, seized headlines, and enthralled the nation.ø In this book, Alder explains why America?and only America?has embraced this mechanical method of reading the human soul. Over the course of the twentieth century, the lie detector became integral to our justice system, employment markets, and national security apparatus, transforming each into a game of bluff and bluster. The lie detector device may not reliably read the human mind, but this lively account shows that the instrument?s history offers a unique window into the American soul.

The polygraph, often portrayed as a magic mind-reading machine, is still controversial among experts, who continue heated debates about its validity as a lie-detecting device. As the nation takes a fresh look at ways to enhance its security, can the polygraph be considered a useful tool? The Polygraph and Lie Detection puts the polygraph itself to the test, reviewing and analyzing data about its use in criminal investigation, employment screening, and counter-intelligence. The book looks at: The theory of how the polygraph works and evidence about how deceptivenessâ€"and other psychological conditionsâ€"affect the physiological responses that the polygraph measures. Empirical evidence on the performance of the polygraph and the success of subjects' countermeasures. The actual use of the polygraph in the arena of national security, including its role in deterring threats to security. The book addresses the difficulties of measuring polygraph accuracy, the usefulness of the technique for aiding interrogation and for deterrence, and includes potential alternativesâ€"such as voice-stress analysis and brain measurement techniques.

This book will enable you to determine whether or not someone is lying to you. Contains over 60 axioms or guidelines that put your subject through the gauntlet. From FBI Agent to Housewife, you need to read this book. After you do, you will never look at the NEWS, political speeches, or anything that the government tells you in the same light. Conceived in an environment of pathological liars, this book takes "common sense" to a new level. Some deceptions are very subtle and nefarious, and some deceptions are your own conclusions - which you arrive at by the design of the liar - or government - which tells you only what will lead you to believe their lies

This book develops a sociological account of lie detection practices and uses this to think about lying more generally. Bringing together insights from sociology, social history, socio-legal studies and science and technology studies (STS), it explores how torture and technology have been used to try to discern the truth. It examines a variety of socio-legal practices, including trial by ordeal in Europe, the American criminal jury trial, police interrogations using the polygraph machine, and the post-conviction management of sex offenders in the USA and the UK. Moving across these different contexts, it articulates how uncertainties in the use of lie detection technologies are managed, and the complex roles they play in legal spaces. Alongside this story, the book surveys some of the different ways in which lying is understood in philosophy, law and social order. Lie Detection and the Law will be of interest to STS researchers, socio-legal scholars, criminologists and sociologists, as well as others working at the intersections of law and science.

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.
