The story of the lie detector takes us straight into the dark recesses of the American soul. It also leads us on a noir journey through some of the most storied episodes in American history. That is because the device we take for granted as an indicator of guilt or innocence actually tells us more about our beliefs than about our deeds. The machine does not measure deception so much as feelings of guilt or shame. As Ken Alder reveals in his fascinating and disturbing account, the history of the lie detector exposes fundamental truths about our culture: why we long to know the secret thoughts of our fellow citizens; why we believe in popular science; and why America embraced the culture of "truthiness." For centuries, people searched in vain for a way to unmask liars, seeking clues in blushing cheeks, shifty eyes, and curling toes...all the body's outward signs. But not until the 1920s did a cop with a Ph.D. team up with an entrepreneurial high school student from Berkeley, California and claim to have invented a foolproof machine that peered directly into the human heart. In a few short years their polygraph had transformed police work, seized headlines, solved sensational murders, and enthralled the nation. In Chicago, the capital of American vice, the two men wielded their device to clean up corruption, reform the police, and probe the minds of infamous killers. Before long the lie detector had become the nation's "mechanical conscience," searching for honesty on Main Street, in Hollywood, and even within Washington, D.C. Husbands and wives tested each other's fidelity. Corporations tested their employees' honesty. Movie studios and advertisers tested their audiences' responses. Eventually, thousands of government employees were tested for their loyalty and "morals" -- for lack of which many lost their jobs. Yet the machine was flawed. It often was used to accuse the wrong person. It could easily be beaten by those who knew how. Repeatedly it has been applied as an instrument of psychological torture, with the goal of extracting confessions. And its creators paid a commensurate price. One went mad trying to destroy the Frankenstein's monster he had created. The other became consumed by mistrust: jealous of his cheating wife, contemptuous of his former mentor, and driven to an early death. The only happy man among the machine's champions was the eccentric psychologist who went on to achieve glory as the creator of Wonder Woman. Yet this deceptive device took America -- and only America -- by storm. Today, the CIA still administers polygraphs to its employees. Accused celebrities loudly trumpet its clean bill of truth. And the U.S. government, as part of its new "war on terror," is currently exploring forms of lie detection that reach directly into the brain. Apparently, America still dreams of a technology that will render human beings transparent. The Lie Detectors is the entertaining and thought-provoking story of that American obsession.

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.

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

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 apresents an examination of the contribution that polygraph testing can make to offender treatment programmes, with a particular focus on sexual offenders. This book features coverage of a very timely issue - the British Psychological Society has convened a working party to assess the contribution of the polygraph to forensic work.
