Taking A Stand On Taking The Stand: The Effect Of A Prior Criminal Record On The Decision To Testify And On Trial Outcomes, Theodore Eisenberg, Valerie P. Hans
Taking A Stand On Taking The Stand: The Effect Of A Prior Criminal Record On The Decision To Testify And On Trial Outcomes, Theodore Eisenberg, Valerie P. Hans
Cornell Law Faculty Publications
This article uses unique data from over 300 criminal trials in four large counties to study the relations between the existence of a prior criminal record and defendants testifying at trial, between testifying at trial and juries' learning about a criminal record, and between juries' learning about a criminal record and their decisions to convict or acquit. Sixty percent of defendants without criminal records testified compared to 45 percent with criminal records. For testifying defendants with criminal records, juries learned of those records in about half the cases. Juries rarely learned about criminal records unless defendants testified. After controlling for …
Burden Of Proof, Prima Facie Case And Presumption In Wto Dispute Settlement, John J. Barceló Iii
Burden Of Proof, Prima Facie Case And Presumption In Wto Dispute Settlement, John J. Barceló Iii
Cornell Law Faculty Publications
The essay maintains that the WTO Appellate Body's concepts and terminology concerning a claimant's burden of proof-the concepts of prima facie case, presumption, and burden shifting-are disturbingly ambiguous and potentially misleading. This is so whether one thinks of these terms from either a common law or a civil law perspective. In the face of the current ambiguity, a future panel might understand the AB's prima facie case concept to require an overwhelming level of proof from the claimant. On the other hand, a different panel might allow a rather weak level of claimant's proof to meet the prima facie requirement, …
Science In The Jury Box: Jurors' Views And Understanding Of Mitochondrial Dna Evidence, Valerie P. Hans, David H. Kaye, B. Michael Dann, Erin J. Farley, Stephanie Albertson

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 …
Can Judges Ignore Inadmissible Information? The Difficulty Of Deliberately Disregarding, Andrew J. Wistrich, Chris Guthrie, Jeffrey J. Rachlinski
Can Judges Ignore Inadmissible Information? The Difficulty Of Deliberately Disregarding, Andrew J. Wistrich, Chris Guthrie, Jeffrey J. Rachlinski

Due process requires courts to make decisions based on the evidence before them without regard to information outside of the record. Skepticism about the ability of jurors to ignore inadmissible information is widespread. Empirical research confirms that this skepticism is well-founded. Many courts and commentators, however, assume that judges can accomplish what jurors cannot. This article reports the results of experiments we have conducted to determine whether judges can ignore inadmissible information. We found that the judges who participated in our experiments struggled to perform this challenging mental task. The judges had difficulty disregarding demands disclosed during a settlement conference, …
