Available in PDF, EPUB and Kindle. Book excerpt: 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.
Download or read book Critical Reflections on Evidence Based Policing written by Taylor & Francis Group and published by Routledge. This book was released on 2021-06-30 with total page 216 pages. Available in PDF, EPUB and Kindle. Book excerpt: Evidence-Based Practice (EBP) has over the last decade made an increasing mark in several fields, notably health and medicine, education and social welfare. In recent years it has begun to make its mark in criminal justice. As engagement with EBP has spread, it has begun to evolve from what might be regarded as a somewhat narrow doctrine and orthodoxy to something more complex and various. Often criminological research has been at odds with the assumptions, conventions and methodologies associated with first generation EBP. In that context EBP poses a challenge to the research community and existing evidence base and is, accordingly, hotly controversial. This book is a welcome and timely contribution to current debates on evidence-based practice in policing. With a sharp conceptual focus, the chapters provide a critical examination of the recent history of EBP in academic, policy and practitioner communities, evaluate key dimensions of its application to policing, challenge established understandings and pave the way for a much needed change in how research 'evidence' is perceived, generated, transferred, implemented and evaluated.

Available in PDF, EPUB and Kindle. Book excerpt: Throughout history, there has been an intrinsic need for humans to detect deception in other humans. Developed in 1923, the polygraph machine was a tool designed to do just this. To date, there have been many improvements made to the basic polygraph instrument. This book outlines the instrumentation as well as the latest in questioning techniques and methods available to the professional interviewer to determine truth from deception. The book covers psychology and physiology, a history of polygraph with the advances of leading figures, question formulation, data analysis, legal implications and legal cases, and the author’s developed technique Integrated Zone Comparison Technique (IZCT).

Download or read book A Tremor In The Blood written by David T. Lykken and published by . This book was released on 1998-03-21 with total page 360 pages. Available in PDF, EPUB and Kindle. Book excerpt: The author presents case histories of persons whose lives have been blighted by our uniquely American faith in the myth of the lie detector. Dr. Lykken also explains how to "beat" the machine, not only because it is unfair that spies and Mafia soldiers already know these techniques, but also because innocent persons have nearly a 50:50 chance of failing lie detector tests unless they use appropriate countermeasures. Many state courts in the U.S. still admit lie detector tests into evidence under certain conditions - a practice that ensures the conviction of more innocent people every year. Finally, Dr. Lykken reports on the results of recent surveys of informed scientific opinion about lie detection and presents another method of polygraphic interrogation that is designed to detect, not lies, but the presence of guilty knowledge. This method is scientifically credible and holds promise for future use in criminal investigation.
Download or read book Gatekeeper written by John F. Sullivan and published by Potomac Books, Inc.. This book was released on 2011 with total page 411 pages. Available in PDF, EPUB and Kindle. Book excerpt: John F. Sullivan was a polygraph examiner with the CIA for thirty-one years, during which time he conducted more tests than anyone in the history of the CIA's program. The lie detectors act as the Agency's gatekeepers, preventing foreign agents, unsuitable applicants, and employees guilty of misconduct from penetrating or harming the Agency. Here Sullivan describes his methods, emphasizing the importance of psychology and the examiners' skills in a successful polygraph program. Sullivan acknowledges that using the polygraph effectively is an art as much as a science, yet he convincingly argues that it remains a highly reliable screening device, more successful and less costly than the other primary method, background investigation. In the thousands of tests that Sullivan conducted, he discovered double agents, applicants with criminal backgrounds, and employee misconduct, including compromising affairs and the mishandling of classified information. But Gatekeeper is more than Sullivan's memoirs. It is also a window to the often acrimonious and sometimes alarming internal politics of the CIA: the turf wars over resources, personnel, and mandate; the slow implementation of quality control; the aversion to risk-taking; and the overzealous pursuit of disqualifying information. In an age when the intelligence community's conduct is rightly being questioned, Sullivan contributes a fascinating personal account of one of the Agency's many important tasks.

Download or read book The Lie Detectors written by Ken Alder and published by U of Nebraska Press. This book was released on 2009-01-01 with total page 370 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
Download or read book Research in Law Enforcement Selection written by Michael G. Aamodt and published by Universal-Publishers. This book was released on 2004 with total page 224 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is the most comprehensive reference ever written for individuals interested in law enforcement selection. The chapters contain meta-analyses (statistical reviews of the literature) investigating the validity of methods used to predict police performance. These methods include education requirements, cognitive ability, background variables (e.g., military experience, arrest record, discipline problems at work), personality inventories, interest inventories, physical agility tests, assessment centers, and interviews. The first chapter in the book is a short primer on meta-analysis that informs the reader about the purpose of meta-analysis and how to interpret the meta-analysis tables contained in the book. Chapter 2 describes the methods used to conduct the meta-analyses for this project. Chapters 3-11 list the meta-analysis results for the various predictors of police performance. Chapter 12 describes a meta-analysis of the relationships among criteria (e.g., performance ratings, discipline problems, commendations), Chapter 13 describes a meta-analysis of the relationships among selection methods, and Chapter 14 describes a meta-analysis of the relationship between the various criteria and sex, race, age, and tenure. Chapter 15 summarizes the previous chapters and identifies future research needs.
