From a Rigid Cover to an Elastic One Via a Blanket too Short. An Adaptive
Polygraph Approach
- Abstract: The Polygraph test or the Psychophysiological Detection of Deception is a short blanket that cannot cover everything without paying in errors; a clever polygraph examiner and a wise usage of polygraph must make a choice whether to cover the feet or the head with this short blanket and conduct the examination accordingly. But a wiser approach should look to turn the short blanket into an elastic cover that can deal differently with different people and different situations.Following two-three decades of blessed efforts to develop strict standardization in the field, the time has come to start steering the polygraph ship back to greater flexibility and creativity, this time relying on scientific thinking and knowledge. Thus, contrary to the existing trend in the field, I call to drive modern Polygraphy towards developing a scientifically based approach that follows the motto of “Different Things to Different People and Different Situations”. In other words, I call for developing an adaptive approach or Adaptive Polygraphy. The Relevant Issue Gravity (RIG) Theory (Ginton, 2009) is presented here as a major theoretical and practical carrier for evolving and shaping the Adaptive Polygraphy. The article analyzes the current situation and draws some lines to follow in developing an Adaptive Polygraphy approach.

Directed Lie – The Correct or the Easy Way'
- Abstract: Lately there had been a huge push in our profession toward the use to use the Directed Lie Comparison question (DLC). The truth verification field is divided into “pro and con” towards this idea, like many things in life. This article will research whether this “new fashion” is really the correct way or the easy or lazy way to conduct psychophysiological truth verification examinations, as well as make comparisons between the advantages and disadvantages between the DLC and the Probable Lie Comparison question (PLC).

Evidence Based Practice Integration into Polygraph Practice: A suggested
paradigm
- Abstract: The philosophy of evidence-based practice advocates professionals to rely on scientific evidence. Although the idea seems obvious, misuse of the philosophy raised controversy, which created confusion and misunderstanding of the concept. Yet, since it was introduced in the nineties to the medical community and despite the controversy, it gained more and more disciples and was embraced by nonmedical practitioners, including the polygraph profession. In the last decades, the polygraph community has gradually abandoned the intuitive-based polygraph practice that relies on less scientifically rooted subjective procedures and advanced toward evidence-based polygraph practice. This paper describes the evidence-based practice in general and details the practical aspects of evidence-based polygraph practice in particular, along with discussing the limitations of the current scientific research. It questions the current bone-tone trend to implement an extreme Evidence-Based approach into the polygraph practice, suggesting the practitioner to avoid a rigid “one size fit all” standardized protocols which are advocated as a must on the way to earn scientific recognition, whereas, in fact, it is the unfortunate outcome of lack of differential research data. As in the medical field, in-where the Evidence-Based practice managed to incorporate the clinical experience of experts with the hard research evidence and has not disregarded their valuable knowledge and experience, the present article calls for adopting this integrative approach in the polygraph field too and adjust the protocols to the specific circumstances of the case and the examinee in a “tailor-made” mode, which is based on existing data and flexible thinking wherever there is no data to rely on, as was suggested under the concept of “Adaptive-Polygraphy” (Ginton, 2013).

Electrodermal Response Ratios: Scoring Against the Stronger of Two
Comparison Questions in Search of an Optimal Minimum Threshold
- Abstract: Previously, Krapohl (2020) evaluated the Bigger-Is-Better Rule (BIBR) on the polygraph electrodermal channel to assess whether there was a best minimum ratio between response sizes for assigning a score. Performance peaked at a minimum ratio between 10% and 20%. The ratios had been calculated by comparing the electrodermal responses for each relevant question against those of the immediately preceding comparison question. The analysis did not consider whether the same optimal ratio would be found if the relevant question electrodermal responses are compared to those of the stronger of two adjacent comparison questions. To investigate we analyzed responses from an independent sample of 255 laboratory cases. The data from those cases found the highest correlation between scores and ground truth occurred when the minimum difference between two electrodermal responses was 30%.

Trying an Accused Serial Sexual Harasser for Libel in a US Civil Court
- Abstract: The goal of this article is to provide a class of MeToo# victims of a high-profile serial sexual harasser with a non-invasive method for civil action, when the accused publicly dismisses the victims’ claims as lies. When these libelous claims do occur, the victims can be assembled into a class-action libel/defamation case, which in most US states must be mounted within two years of the claim. Because under current civil methods, the plaintiffs would be subject to intense cross-examination in a civil jury trial, class-action lawsuits with small numbers of plaintiffs (e.g. 5–8) have proven impossible to conduct. This article provides a blueprint to create a collaboration amongst the victims, credibility-assessment (lie-detector) experts, statisticians, and MeToo# attorneys to litigate libel suits, which will likely produce out-of-court settlements. Once the first case is successfully completed, precedent will be set to bring other perpetrators to justice, and act as a deterrent to future exploitation. The evidentiary basis would be based on testing the null hypothesis that all plaintiffs are lying, to compare the inferred lying rates of the plaintiffs to similar population controls, who would be known liars, to a “Yes” answer to “Did X sexually harass you'”
