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 …

Maintaining Competition In Copying: Narrowing The Scope Of Gene Patents, Oskar Liivak

Cornell Law Faculty Publications

In supporting gene patents, the patent office, the courts and other supporters have assumed that gene discoveries are identical to traditional inventions and therefore the patent system should treat them as identical. In other words, they have assumed that the relatively broad claims that are used for traditional inventions are also appropriate for encouraging gene discovery. This article examines this assumption and finds that gene discoveries are critically different from traditional inventions and concludes that the patent system cannot treat them as identical.

As a doctrinal matter, this article applies the generally overlooked constitutional requirements of inventorship and originality and …

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.
