An Economic Analysis Of Fact Witness Payment, Eugene Kontorovich, Ezra Friedman
An Economic Analysis Of Fact Witness Payment, Eugene Kontorovich, Ezra Friedman
Faculty Working Papers
In this paper we discuss the disparate treatment of perceptual (''fact'') witnesses and expert witnesses in the legal system. We highlight the distinction between the perceptual act of witnessing and the act of testifying, and argue that although there might be good reasons to regulate payments to fact witnesses, the customary prohibition on paying them for their services is not justified by reference to economic theory. We propose considering a court mediated system for compensating fact witnesses so as to encourage witnessing of legally important events.We construct a simple model of witness incentives, and simulate the effects of several possible …
The Need For A Research Culture In The Forensic Sciences, Jonathan Koehler, Jennifer L. Mnookin, Simon A. Cole, Barry A.J. Fisher, Itiel E. Dror, Max Houck, Kieth Inman, David H. Kaye, Glenn Langenburg, D. Michel Risinger, Norah Rudin, Jay Siegel

Faculty Working Papers
The methods, techniques, and reliability of the forensic sciences in general, and the pattern identification disciplines in particular, have faced significant scrutiny in recent years. Critics have attacked the scientific basis for the assumptions and claims made by forensic scientists both in and out of the courtroom. Defenders have emphasized courts' long-standing acceptance of forensic science evidence, the relative dearth of known errors, and the skill and experience of practitioners. This Article reflects an effort made by a diverse group of participants in these debates, including law professors, academics from several disciplines, and practicing forensic scientists, to find and explore …
What Will We Lose If The Trial Vanishes?, Robert P. Burns
What Will We Lose If The Trial Vanishes?, Robert P. Burns
Faculty Working Papers
The number of trials continues to decline andfederal civil trials have almost completely disappeared. This essay attempts to address the significance of this loss, to answer the obvious question, "So what?" It argues against taking a resigned or complacent attitude toward an important problem for our public culture. It presents a short description of the trial's internal structure, recounts different sorts of explanations, and offers an inventory of the kinds of wounds this development would inflict.
Moral Character, Motive, And The Psychology Of Blame, Janice Nadler, Mary-Hunter Morris Mcdonnell
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
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 …
Proficiency Tests To Estimate Error Rates In The Forensic Sciences, Jonathan Koehler
Proficiency Tests To Estimate Error Rates In The Forensic Sciences, Jonathan Koehler
Faculty Working Papers
A proficiency test is an assessment of the performance of laboratory personnel using samples whose sources are known to the proficiency test administrator but unknown to the examinee. Proficiency tests can help identify reasonable first pass estimates for the rates at which various types of errors occur. It is crucial to obtain error rate estimates because the reliability and probative value of forensic science evidence is inextricably linked to the rates at which examiners make errors. Without such information, legal decision makers have no scientifically meaningful way of thinking about the risk of false identification and false non-identification associated with …
