Statistics In The Jury Box: How Jurors Respond To Mitochondrial Dna Match Probabilities, David H. Kaye, Valerie P. Hans, B. Michael Dann, Erin J. Farley, Stephanie Albertson

Cornell Law Faculty Publications

This article describes parts of an unusually realistic experiment on the comprehension of expert testimony on mitochondrial DNA (mtDNA) sequencing in a criminal trial for robbery. Specifically, we examine how jurors who responded to summonses for jury duty evaluated portions of videotaped testimony involving probabilities and statistics. Although some jurors showed susceptibility to classic fallacies in interpreting conditional probabilities, the jurors as a whole were not overwhelmed by a 99.98% exclusion probability that the prosecution presented. Cognitive errors favoring the defense were more prevalent than ones favoring the prosecution. These findings lend scant support to the legal argument that mtDNA …

Please, Let's Bury The Junk: The Codis Loci And The Revelation Of Private Information, David H. Kaye

Journal Articles

This Northwestern University Law Review Colloquy paper describes the four possible ways in which genetic loci could possess predictive or diagnostic value with regard to diseases and explains why these mechanisms have not led, and probably cannot lead, to useful screening tests with the Convicted Offender DNA Index System (CODIS) profiles in national, state, and local databases. It then considers the phenotypes and familial relationships that the CODIS STRs can be used to identify. The profiles carry limited information about an individual's race and familial relationships, and the article places the resulting privacy issues in perspective. Finally, the paper comments …

The Science Of Dna Identification: From The Laboratory To The Courtroom (And Beyond), David H. Kaye

Journal Articles

This article focuses on sequences of DNA base-pairs, which are becoming increasingly important in the field of law. These DNA sequences are used by forensic scientists to discover evidence such as blood stains, semen, saliva, and hair, and has become highly useful in the courtroom with regard to exonerating the innocent and convicting the guilty. Part I of the article examines how courts may (or may not) admit DNA evidence in court through four phases: uncritical acceptance; serious challenges to analytical methods and statistical interpretation of the results; renewed acceptance of DNA evidence; and acceptance of advance systems of DNA …

Prosecutors, Ethics, And Expert Witnesses, Paul C. Giannelli, Kevin C. Mcmunigal

Faculty Publications

Commentators who have examined the DNA exonerations have noted the disturbing role that prosecutors have played in these wrongful convictions. Another significant contributor to these miscarriages of justice is the misuse of expert testimony, a third of the cases according to some sources. This Article examines the intersection of these two factors - the prosecutor's role in using and presenting expert testimony.

Prosecutorial misconduct may occur during most stages of a trial, beginning with the selection of witnesses, including the improper "shopping" for experts. Additional abuses occur when prosecutors fail to abide by rules governing the pretrial disclosure of scientific …

Everything New Is Old Again: Brain Fingerprinting And Evidentiary Analogy, Alexandra J. Roberts

Law Faculty Scholarship

Brain Fingerprinting uses electroencephalography to ascertain the presence or absence of information in a subject's brain based on his reaction to particular stimuli. As a new forensic tool, Brain Fingerprinting technology stands poised to exert a tremendous impact on the presentation and outcome of selected legal cases in the near future. It also provides a fertile case study to examine the role of analogical reasoning in the process by which lawyers, experts, judges, and the media influence how factjinders perceive and evaluate unfamiliar types of proof When juridical metaphor disguises, distorts, or destroys ideas, it ceases to serve as an …

Independent Judicial Research In The "Daubert" Age, Edward K. Cheng

Vanderbilt Law School Faculty Publications

The Supreme Court's Daubert trilogy places judges in the unenviable position of assessing the reliability of often unfamiliar and complex scientific expert testimony. Over the past decade, scholars have therefore explored various ways of helping judges with their new gatekeeping responsibilities. Unfortunately, the two dominant approaches, which focus on doctrinal tests and external assistance mechanisms, have been largely ineffective. This Article advocates for a neglected but important method for improving scientific decision making-independent judicial research. It argues that judges facing unfamiliar and complex scientific admissibility decisions can and should engage in independent library research to better educate themselves about the …

Judges, Juries, And Scientific Evidence, Valerie P. Hans

Cornell Law Faculty Publications

The rise in scientific evidence offered in American jury trials, along with court rulings thrusting judges into the business of assessing the soundness of scientific evidence, have produced challenges for judge and jury alike. Many judges have taken up the duty of becoming “amateur scientists.” But what about juries? Surely they too could benefit from assistance as they attempt to master and apply complex testimony about scientific matters during the course of a trial. Concerns about the jury’s ability to understand, critically evaluate, and employ scientific evidence in deciding complex trials have led to many suggestions for reform.

Maieusis Through A Gated Membrane: "Getting The Science Right" In Public Decisionmaking, Deborah Hussey Freeland

Deborah M. Hussey Freeland

Law meets science in a remarkable variety of contexts. While their interactions are often studied in particular contexts, general theories of their interaction are wanting. This paper presents a general model of an interface between law and science that identifies how their interaction must be structured to promote effective interdisciplinary collaboration, and then demonstrates how this model can be used to analyze problems as diverse as: a large-scale intergovernmental attempt at ecosystem restoration; and the effects of a method of science-based alternative dispute resolution on science and negotiated outcomes. In both cases, the model features of a properly functioning law-science …
