Critical Review Of The Use Of The Rorschach In European Courts, Igor Areh, Fanny Verkampt, Alfred Allan

Research outputs 2014 to 2021

In relation to the admissibility of evidence obtained using projective personality tests arose in F v. Bevándorlási és Állampolgársági Hivatam (2018). The Court of Justice of the European Union has held that an expert’s report can only be accepted if it is based on the international scientific community’s standards, but has refrained from stipulating what these standards are. It appears timely for European psychologists to decide what standards should be applied to determine whether or not a test is appropriate for psycholegal use. We propose standards and then apply them to the Rorschach because it was used in this case …

Latent Print Examination And Human Factors: Improving The Practice Through A Systems Approach: The Report Of The Expert Working Group On Human Factors In Latent Print Analysis, David H. Kaye, Thomas Busey, Melissa R. Gische, Gerry Laporte, Scott A. Shappell, Et Al.

Publications

Fingerprints have provided a valuable method of personal identification in forensic science and criminal investigations for more than 100 years. Fingerprints left at crime scenes generally are latent prints—unintentional reproductions of the arrangement of ridges on the skin made by the transfer of materials (such as amino acids, proteins, polypeptides, and salts) to a surface. Palms and the soles of feet also have friction ridge skin that can leave latent prints. The examination of a latent print consists of a series of steps involving a comparison of the latent print to a known (or exemplar) print. Courts have accepted latent …

PREDATORS AND PROPENSITY: THE PROPER APPROACH FOR DETERMINING THE ADMISSIBILITY OF PRIOR BAD ACTS EVIDENCE IN CHILD SEXUAL ABUSE PROSECUTIONS

Basyle J. Tchividjian†

Abstract

The admissibility of prior bad act evidence in child sexual abuse prosecutions oftentimes makes the difference between a guilty and not guilty verdict. Recently, jurisdictions have growingly embraced the admission of such evidence for the purpose of establishing the defendant’s propensity to sexually victimize children. Due to the potentially high prejudicial effect of admitting propensity evidence, it is more critical than ever that courts carefully apply the decisive evidentiary gatekeeper, the probative value balancing test …

Moral Character, Motive, And The Psychology Of Blame, Janice Nadler, Mary-Hunter Morris Mcdonnell

Faculty Working Papers

Blameworthiness, in the criminal law context, is conceived as the carefully calculated end product of discrete judgments about a transgressor's intentionality, causal proximity to harm, and the harm's foreseeability. Research in social psychology, on the other hand, suggests that blaming is often intuitive and automatic, driven by a natural impulsive desire to express and defend social values and expectations. The motivational processes that underlie psychological blame suggest that judgments of legal blame are influenced by factors the law does not always explicitly recognize or encourage. In this Article we focus on two highly related motivational processes – the desire to …

If The Shoe Fits They Might Acquit: The Value Of Forensic Science Testimony, Jonathan Koehler

Faculty Working Papers

The probative value of forensic science evidence (such as a shoeprint) varies widely depending on how the evidence and hypothesis of interest is characterized. This paper uses a likelihood ratio (LR) approach to identify the probative value of forensic science evidence. It argues that the "evidence" component should be characterized as a "reported match," and that the hypothesis component should be characterized as "the matching person or object is the source of the crime scene sample." This characterization of the LR forces examiners to incorporate risks from sample mix-ups and examiner error into their match statistics. But how will legal …

The Distortionary Effect Of Evidence On Primary Behavior, Gideon Parchomovsky, Alex Stein

All Faculty Scholarship

In this Essay, we analyze how evidentiary concerns dominate actors’ behavior. Our findings offer an important refinement to the conventional wisdom in law and economics literature, which assumes that legal rules can always be fashioned to achieve socially optimal outcomes. We show that evidentiary motivations will often lead actors to engage in socially suboptimal behavior when doing so is likely to increase their likelihood of prevailing in court. Because adjudicators must base decisions on observable and verifiable information—or, in short, evidence—rational actors will always strive to generate evidence that can later be presented in court and increase their chances of …

Dangerousness And Expertise Redux, Christopher Slobogin

Vanderbilt Law School Faculty Publications

Civil commitment, confinement under sexual predator laws, and many capital and noncapital sentences depend upon proof of a propensity toward violence. This Article discusses the current state of prediction science, in particular the advantages and disadvantages of clinical and actuarial prediction, and then analyzes how the rules of evidence should be interpreted in deciding whether opinions about propensity should be admissible. It concludes that dangerousness predictions that are not based on empirically derived probability estimates should be excluded from the courtroom unless the defense decides otherwise. This conclusion is not bottomed on the usual concern courts and commentators raise about …
