The American Polygraph Association (APA) believes that scientific evidence supports the validity of polygraph examinations that are conducted and interpreted in compliance with documented and validated procedure. Thus, such examinations have great probative value and utility for a range of uses, including criminal investigations, offender management, and selection of applicants for positions requiring public trust. The APA Standards of Practice set some of the highest professional requirements for its members to ensure their polygraph services are valuable, reliable, and promote ethically responsible practices. The APA also produces a variety of model policies that represent the current understanding of best practices, and makes them widely available so that polygraph examiners (both APA members and non-members) and their clients can be aware of what constitutes a valid examination process. The APA believes that well informed departments, agencies, and clients will insist on APA members for their polygraph services.
Recently the APA undertook an exhaustive review of all of the peer-reviewed publications on polygraph testing that represented field practices and which met the requirements of the APA Standards of Practice. A meta-analysis was conducted, and a report was completed in late 2011.
The executive summary reports that 38 studies satisfied the qualitative and quantitative requirements for inclusion in the meta-analysis. These studies involved 32 different samples, and described the results of 45 different experiments and surveys. They included 295 scorers who provided 11,737 scored results of 3,723 examinations, including 6,109 scores of 2,015 confirmed deceptive examinations, 5,628 scores of 1,708 confirmed truthful exams. Some of the cases were scored by multiple scorers and using multiple scoring methods. The data showed that techniques intended for event-specific (single issue) diagnostic testing produced an aggregated decision accuracy of 89% (confidence interval of 83% – 95%), with an estimated inconclusive rate of 11%. Polygraph techniques in which multiple issues were encompassed by the relevant questions produced an aggregated decision accuracy of 85% (confidence interval 77% – 93%) with an inconclusive rate of 13%. The combination of all validated PDD techniques, excluding outlier results, produced a decision accuracy of 87% (confidence interval 80% – 94%) with an inconclusive rate of 13%. These findings were consistent with those of the National Research Council’s (2003) conclusions regarding polygraph accuracy, and provide additional support for the validity of polygraph testing when conducted in accordance with APA Standards of Practice.
AUSTIN, Texas (AP) — Some Texas lawmakers suggested Tuesday that Syrian refugees take lie-detector tests to weed out potential extremists as state leaders defended suing the U.S. government in so far unsuccessful efforts to keep families fleeing the war-torn country out of the state.
The idea of a polygraph was endorsed as having “value” by Texas Department of Public Safety Director Steve McCraw, even while he told members of the Texas Legislature that states have no role vetting refugees. One lawmaker pushing for polygraphs compared it to police officers taking lie-detector exams during the hiring process.
“If we can do it for law enforcement to qualify certain law enforcement positions, it may be something we can consider,” Democratic state Rep. Richard Peña Raymond said.
63 Sex Offenders back in Jail after Lie Detector Tests
Pedophiles and rapists are caught out breaking the terms of their release from prison after undergoing new polygraph tests, Ministry of Justice figures show
In the past year, 492 people convicted of serious sex offences such as rape and child abuse in England and Wales have been forced to take polygraph tests under the terms of their release from custody “on license”.
New figures showed 63 of these individuals – 13 per cent – were put back behind bars after the tests showed they had breached the conditions of their release.
Officials said the tests had shown that some pedophiles who were released on license before the end of their sentences posed an “immediate risk” to children. These individuals were then sent back to jail.
A succession of cases in recent years has shown offenders released early have offended again and the tests, introduced last year, are designed to prevent re-offending by pedophiles and other sex attackers.
In one case, a man convicted of sexual offences against a child was released into the community after a lengthy prison term. He then took a lie detector test to assess whether he had complied with the conditions of his early release – which included a ban on using the internet without approval.
The offender, who has not been named, was found to have lied during the polygraph test but the results still revealed that he had been using the internet.
When confronted with the findings and questioned again, he confessed that he had viewed indecent images of children online. Police then searched his home and found these images saved onto data storage devices hidden at the property. He was then was charged with further offences and sent back to prison.
Lyndsey Walker, a polygraph examiner, has carried out more than 60 tests under the new system, which came into operation last August. She said the test had proved to be “invaluable” in keeping the public safe.
“My polygraph sessions have frequently resulted in serious sex offenders making disclosures which have shown they either aren’t complying with the conditions of their release or that they pose an increased risk to the public,” she said. “I have seen sex offenders make admissions that prove they pose an imminent risk to children allowing authorities to take appropriate action to keep communities safe.”
Offenders who take the lie-detector tests are twice as likely to confess to breaking the conditions of their release – and therefore ending up back in prison.
Offenders convicted of the most serious sex crimes must undergo a test in their first three months after being released, and then again once every six months.
Andrew Selous, the Prisons and Probation Minister, said: “Lie detector tests play a vital part in supervising high risk sex offenders. Those who cannot comply with their license conditions are being returned to prison which shows the success of the tests and helps us to keep the public safer.”
