    Honesty Without Truth: Lies, Accuracy, and the Criminal Justice Process

    Focusing on “lying” is a natural response to uncertainty but too narrow of a concern. Honesty and truth are not the same thing and conflating them can actually inhibit accuracy. In several settings across investigations and trials, the criminal justice system elevates compliant statements, misguided beliefs, and confident opinions while excluding more complex evidence. Error often results. Some interrogation techniques, for example, privilege cooperation over information. Those interactions can yield incomplete or false statements, confessions, and even guilty pleas. Because of the impeachment rules that purportedly prevent perjury, the most knowledgeable witnesses may be precluded from taking the stand. The current construction of the Confrontation Clause right also excludes some reliable evidence—especially from victim witnesses—because it favors face-to-face conflict even though overrated demeanor cues can mislead. And courts permit testimony from forensic experts about pattern matches, such as bite-marks and ballistics, if those witnesses find their own methodologies persuasive despite recent studies discrediting their techniques. Exploring the points of disconnect between honesty and truth exposes some flaws in the criminal justice process and some opportunities to advance fact-finding, truth-seeking, and accuracy instead. At a time when “post-truth” challenges to shared baselines beyond the courtroom grow more pressing, scaffolding legal institutions, so they can provide needed structure and helpful models, seems particularly important. Assessing the legitimacy of legal outcomes and fostering the engagement necessary to reach just conclusions despite adversarial positions could also have an impact on declining facts and decaying trust in broader public life

    How private is private information?:The ability to spot deception in an economic game

    We provide experimental evidence on the ability to detect deceit in a buyer-seller game with asymmetric information. Sellers have private information about the buyer's valuation of a good and sometimes have incentives to mislead buyers. We examine if buyers can spot deception in face-to-face encounters. We vary (1) whether or not the buyer can interrogate the seller, and (2) the contextual richness of the situation. We find that the buyers' prediction accuracy is above chance levels, and that interrogation and contextual richness are important factors determining the accuracy. These results show that there are circumstances in which part of the information asymmetry is eliminated by people's ability to spot deception

    Lie detectors can be applied in a wide variety of settings. But this advantage comes with a considerable cost: False positives. The applicability of the Concealed Information Test (CIT) is More limited, yet when it can be applied, the risk of false accusations can be set a priori at a very low level. The CIT assesses the recognition of; critical information that is known only by the examiners and the culprit, for example, the face a an accomplice. Large effects are Obtained with the CIT, whether combined with peripheral, brain, or Motor responses. We see three important challenges for the CIT. First, the false negative rate Of the CIT can be substantial, particularly under :realistic circumstantes. A possible solution Seems to restrict the CIT to highly Salient details. Second, there exist effective faking strategies. Future research will tell whether faking can be detected or even prevented (e.g., Using Overt measures). Third, recognition of critical crime detail's does not necessarily result from criminal activity. It is therefore important to properly embed the CIT in the investigative process, While taking care when drawing conclusions from the test outcome (recognition, not guilt)

    Deception detection process and accuracy: an examination of how international military officers detect deception in the workplace

    This thesis replicates recent diagnostic utility studies to determine whether the original methods are (1) generalizable to a new population and (2) useful in identifying specific questioning strategies relevant to international militaries. Previous research shows that people are, on average, only slightly better-than-chance at detecting deception. In 2006, Personality and Social Psychology Review published Accuracy of Deception Judgments in which Charles F. Bond Jr. and Bella DePaulo identified that meta-analysis yields an across-study average accuracy rate of about 54%. New research has shifted from the historical cue-based deception detection paradigm in favor of the idea of diagnostic utility. Specifically, this new line of research provides a basis for demonstrating that the design of specific questions is vital in determining deceptive individuals. Currently, the research conducted thus far provides levels of deception detection accuracy significantly greater than the usual slightly-better-than-chance results that is characterized by historical research. Our findings from quantitative Study 1 demonstrated that international military officer participants detected deception at 70.8% for experts and 63.8% for non-experts. Finally, the authors’ qualitative Study 2 identified that participant’s claim to have utilized third-party information, physical information, and verbal/nonverbal clues most often when detecting deception in previous situations. These findings are in line with historical research.http://archive.org/details/deceptiondetecti1094545212Outstanding ThesisEnsign, United States NavyMajor, United States Marine CorpsApproved for public release; distribution is unlimited
