This brief addresses the issue of jury performance and jury responses to expert testimony. It reviews and summaries a substantial body of research evidence about jury behavior that has been produced over the past quarter century. The great weight of that evidence challenges the view that jurors abdicate their responsibilities as fact finders when faced with expert evidence or that they are pro-plaintiff, anti-defendant, and anti-business.
The Petitioners and amici on behalf of petitioners make a number of overlapping, but empirically unsupported, assertions about jury behavior in response to expert testimony, namely that juries are frequently incapable of critically evaluation …
Economic Authority And The Limits Of Expertise In Antitrust Cases, John E. Lopatka, William H. Page
Economic Authority And The Limits Of Expertise In Antitrust Cases, John E. Lopatka, William H. Page
William H. Page
In antitrust litigation, the factual complexity and economic nature of the issues involved require the presentation of economic expert testimony in all but a few cases. This dependence on economics has increased in recent years because of the courts' narrowing of per se rules of illegality and the courts' expansion of certain areas of factual inquiry. At the same time, however, courts have limited the scope of allowable expert testimony through the methodological strictures of Daubert and its progeny and through heightened sufficiency requirements. In this Article, Professors Page and Lopatka make four important points about these judicially imposed constraints …

On a late summer evening in August of 1997, Nathan Brown was in his apartment rocking his young daughter to sleep when the police knocked on his door. The police sought Brown, one of a few Black men in his apartment complex, after a young White woman said she had been assaulted by a shirtless Black man wearing black shorts with strong body odor walking through the complex’s courtyard. Minutes later the police took Brown outside and put him in the patrol car for a one-on-one “showup.” They brought him out by himself to see the victim wearing black shorts …
Polygraph Admission Through Compulsory Process, Timothy J. Walsh
Polygraph Admission Through Compulsory Process, Timothy J. Walsh
Akron Law Review
Polygraph evidence is included within the broad category of expert testimony, yet it is treated quite differently from other forms of expert testimony. If admissible at all for the defense, polygraph evidence almost always requires the stipulation of the prosecution for it to be admitted into court. Such a requirement vests solely, within the hands of a prosecutor, the ability to eliminate that proof which may be necessary for the defendant to effectively prove his innocence. Furthermore, in some jurisdictions a defendant cannot even place his faith in the sympathy of a prosecutor. Instead, a rule bars him from proving …
The Trial Judge As Gatekeeper For Scientific Evidence: Will Ohio Rule Of Evidence 102 Frustrate The Ohio Courts' Role Under Daubert V. Merrell Dow?, Michael Lepp, Chrisopher B. Mcneil
The Trial Judge As Gatekeeper For Scientific Evidence: Will Ohio Rule Of Evidence 102 Frustrate The Ohio Courts' Role Under Daubert V. Merrell Dow?, Michael Lepp, Chrisopher B. Mcneil
Akron Law Review
This article considers the role of the trial court in responding to the changes wrought by scientific innovation. Particular consideration is given to the impact likely to be realized in Ohio trial courts from the decision of the United States Supreme Court in Daubert v. Merrell Dow Pharmaceuticals, Inc.
[...]In order to appreciate the significance of Ohio Evidence Rule 102 in this context, it is helpful to first examine some of the events leading to Daubert, especially the application (and in some instances, the rejection) of Frye both in Ohio and at the federal level. Following that, this article will …
Get On Board For The Ride Of Your Life! The Ups, The Downs, The Twists, And The Turns Of The Applicability Of The "Gatekeeper" Function To Scientific And Non-Scientific Expert Evidence: Kumho'sexpansion Of Daubert, Leslie Morsek
Akron Law Review
This Comment examines the history of scientific and non-scientific expert evidence, its current status, and the future of scientific and non-scientific evidence based on recent court decisions. Part II explores the background of these issues by examining the earlier standard for admitting expert testimony, the effect of Congress’ promulgation of the Federal Rules of Evidence, and the influential cases in this area. Part III analyzes the importance of subjecting nonscientific expert testimony to the same rigors as scientific expert testimony. Lastly, Part IV predicts the future of expert evidence.
Jurors' Evaluations Of Expert Testimony: Judging The Messenger And The Message, Sanja Kutnjak Ivkovic, Valerie P. Hans
Jurors' Evaluations Of Expert Testimony: Judging The Messenger And The Message, Sanja Kutnjak Ivkovic, Valerie P. Hans

Jurors are laypersons with no specific expert knowledge, yet they are routinely placed in situations in which they need to critically evaluate complex expert testimony. This paper examines jurors' reactions to experts who testify in civil trials and the factors jurors identify as important to expert credibility. Based on in-depth qualitative analysis of interviews with 55 jurors in 7 civil trials, we develop a comprehensive model of the key factors jurors incorporate into the process of evaluating expert witnesses and their testimony. Contrary to the frequent criticism that jurors primarily evaluate expert evidence in terms of its subjective characteristics, the …

Science On Trial, Valerie P. Hans

The increasing complexity of both criminal and civil jury trials raises a host of issues for lawyers and judges. For the litigator, the first question is whether a jury can be trusted with a case that turns on highly technical evidence. For the trial judge, there are decisions about the admissibility of expert testimony, whether it is based on sound science, and whether a jury is likely to be misled by scientific claims. Should the judge permit jury innovations such as note taking, question asking, and juror discussions of evidence during the trial, hoping to increase jury comprehension of the …
Can Jury Trial Innovations Improve Juror Understanding Of Dna Evidence?, B. Michael Dann, Valerie P. Hans, David H. Kaye
Can Jury Trial Innovations Improve Juror Understanding Of Dna Evidence?, B. Michael Dann, Valerie P. Hans, David H. Kaye
Valerie P. Hans
A single spot of blood on a pink windowsill will tell investigators who broke a windowpane, turned a lock, and kidnapped 2-year-old Molly Evans from her bedroom in the middle of the night. An expert witness will testify that the DNA profile of the blood evidence recovered from the windowsill was entered into CODIS, an electronic database of DNA profiles. That process yielded a “hit,” identifying the defendant as the most likely source of the blood inside Molly’s room. But will jurors be able to understand the expert’s intricate analysis and use it to reach a verdict? And what—if any—steps …

DNA evidence has become a key law enforcement tool and is increasingly presented in criminal trials in Delaware and elsewhere. The integrity of the criminal trial process turns upon the jury's ability to understand DNA evidence and to evaluate properly the testimony of experts. How well do they do? Can we assist them in the process?

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 …

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

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. This article …
