The Incongruence Principle Of Evidence, Hillel Bavli

Indiana Law Journal

Evidence law assumes that the meaning and value of information at trial is equal to the meaning and value of the same information in the real world. This premise underlies evidence policy, judicial applications of evidence law, and instructions to jurors for evaluating evidence. However, it is incorrect, and the law’s failure to recognize this hinders its aims of accuracy and equality.

In this article, I draw on fields outside of law—including Bayesian inference and cognitive psychology—to develop a model of evidence that describes how jurors combine new evidence with prior beliefs (or “priors”) to make inferences and judgments. I …

Shifting The Male Gaze Of Evidence, Teneille R. Brown

Utah Law Faculty Scholarship

In this article I target the altar at which many of us worship—the pursuit of rationality. For evidence purposes, rationality is defined as decisions that are reasonable, objective, inductive, and free from the bias of emotion. This view of rationality is deeply embedded in evidence scholarship and practice. It is also reflected in evidence rules like FRE 403, which treat emotional testimony as unfairly prejudicial simply because it is emotional. The anti-emotion view of rationality reflects the thinking of Western philosophical giants. Plato, Hobbes, Descartes, and Bacon all thought that men should strive for rationality by suppressing their emotions, because …

The Noisy "Silent Witness": The Misperception And Misuse Of Criminal Video Evidence, Aaron M. Williams

Indiana Law Journal

This Note examines recent developments in the research of situational video evidence biases. Part I examines the current and growing body of psychological research into the various situational biases that can affect the reliability of video evidence and the gaps in this research that require further attention from researchers and legal academics. Because these biases do not “operate in a vacuum,” Part I also examines some of the recent and exciting research into the interaction between situational and dispositional biases. Part II examines the development of camera and video processing technology and its limitations as a means of mitigating such …

Social Media, Venue And The Right To A Fair Trial, Leslie Y. Garfield Tenzer

Elisabeth Haub School of Law Faculty Publications

Judicial failure to recognize social media's influence on juror decision making has identifiable constitutional implications. The Sixth Amendment right to a fair trial demands that courts grant a defendant's change of venue motion when media-generated pretrial publicity invades the unbiased sensibility of those who are asked to sit in judgment. Courts limit publicity suitable for granting a defendant's motion to information culled from newspapers, radio, and television reports. Since about 2014, however, a handful of defendants have introduced social media posts to support their claims of unconstitutional bias in the community. Despite defendants' introduction of negative social media in support …

The Inability To Self-Diagnose Bias, Christopher Robertson

Faculty Scholarship

The Constitution guarantees litigants an 'impartial' jury, one that bases its judgment on the evidence presented in the courtroom, untainted by affiliations with the parties, racial animus, or media coverage that may include inadmissible facts, a one-sided portrayal, and naked opinion. Problems of juror bias arise in almost every trial – state and federal, civil and criminal - and the problem is most severe in the highest profile cases, where the need for accuracy and legitimacy in outcomes is most salient.

The Supreme Court has instructed courts to use a simple method to determine whether jurors are biased: ask them. …

The Missing American Jury: Restoring The Fundamental Constitutional Role Of The Criminal, Civil, And Grand Juries, Anna Roberts

Faculty Publications

(Excerpt)

This is a bold book. Professor Thomas urges that the jury—criminal, civil, and grand—be recognized as a fourth “branch” (p. 5). She asserts that procedures that have contributed to the reduction of the jury’s power—including summary judgment and state prosecution without grand juries—are unconstitutional. And, as a Plan B if her constitutional arguments do not prevail, she proposes big changes that include informing juries about sentence exposure, presenting juries with any charges that were offered in plea bargaining, and requiring that juries justify their verdicts.

Bias In Blue: Instructing Jurors To Consider The Testimony Of Police Officer Witnesses With Caution, Vida B. Johnson

Pepperdine Law Review

Jurors in criminal trials are instructed by the judge that they are to treat the testimony of a police officer just like the testimony of any other witness. Fact-finders are told that they should not give police officer testimony greater or lesser weight than any other witness they will hear from at trial. Jurors are to accept that police are no more believable or less believable than anyone else. Jury instructions regarding police officer testimony stand in contrast to the instructions given to jurors when a witness with a legally recognized interest in the outcome of the case has testified. …

Bias, Subjectivity, And Wrongful Conviction, Katherine Judson

Criminal Adjudication, Error Correction, And Hindsight Blind Spots, Lisa Kern Griffin

Washington and Lee Law Review

Concerns about hindsight in the law typically arise with regard to the bias that outcome knowledge can produce. But a more difficult problem than the clear view that hindsight appears to provide is the blind spot that it actually has. Because of the conventional wisdom about error review, there is a missed opportunity to ensure meaningful scrutiny. Beyond the confirmation biases that make convictions seem inevitable lies the question whether courts can see what they are meant to assess when they do look closely for error. Standards that require a retrospective showing of materiality, prejudice, or harm turn on what …

Blackness As Character Evidence, Mikah K. Thompson

Michigan Journal of Race and Law

Federal Rule of Evidence 404 severely limits the government’s ability to offer evidence of a defendant’s character trait of violence to prove action in conformity with that trait on the occasion in question. The Rule states that such character evidence is generally inadmissible when offered to prove propensity. The Rule also allows the government to offer evidence of an alleged victim’s character for peacefulness in homicide cases where the defendant asserts the self-defense privilege. Although criminal defendants may offer character evidence under limited circumstances, Rule 404 creates a significant disincentive for doing so. Where a defendant offers evidence of an …

The Banality Of Wrongful Executions, Brandon L. Garrett

Michigan Law Review

What is so haunting about the known wrongful convictions is that those cases are the tip of the iceberg. Untold numbers of unnoticed errors may send the innocent to prison — and to the death chamber. That is why I recommend to readers a trilogy of fascinating new books that peer deeper into this larger but murkier problem. Outside the rarified group of highly publicized exonerations, which have themselves done much to attract attention to the causes of wrongful convictions, errors may be so mundane that no one notices them unless an outsider plucks a case from darkness and holds …

Effect Of Financial Relationships On The Behaviors Of Health Care Professionals: A Review Of The Evidence, Christopher Robertson, Susannah Rose, Aaron Kesselheim

Faculty Scholarship

This symposium paper explores the empirical evidence regarding the impact of financial relationships on the behavior of health care providers, specifically, physicians. We identify and synthesize peer-reviewed data addressing whether financial incentives are causally related to patient outcomes and health care costs. We cover three main areas where financial conflicts of interest arise and may have an observable relationship to health care practices: physicians’ roles as self-referrers, insurance reimbursement schemes that create incentives for certain clinical choices over others, and financial relationships between physicians and the drug and device industries. We found a well-developed scientific literature consisting of dozens of …

Hearings, Mark Spottswood

Faculty Working Papers

This article explores a constantly recurring procedural question: When is fact-finding improved by a live hearing, and when would it be better to rely on a written record? Unfortunately, when judges, lawyers, and rulemakers consider this issue, they are led astray by the widely shared—but false—assumption that a judge can best determine issues of credibility by viewing the demeanor of witnesses while they are testifying. In fact, a large body of scientific evidence indicates that judges are more likely to be deceived by lying or mistaken witnesses when observing their testimony in person than if the judges were to review …

Blind Expertise, Christopher Robertson

Faculty Scholarship

The United States spends many billions of dollars on its system of civil litigation, and expert witnesses appear in a huge portion of cases. Yet litigants select and retain expert witnesses in ways that create the appearance of biased hired guns on both sides of every case, thereby depriving factfinders of a clear view of the facts. As a result, factfinders too often arrive at the wrong conclusions, thus undermining the deterrence and compensation functions of litigation. Court-appointment of experts has been widely proposed as a solution, yet it raises legitimate concerns about accuracy and has failed to gain traction …

Doctors & Juries, Philip G. Peters Jr.

Michigan Law Review

Physicians widely believe that jury verdicts are unfair. This Article tests that assumption by synthesizing three decades of jury research. Contrary to popular belief the data show that juries consistently sympathize more with doctors who are sued than with patients who sue them. Physicians win roughly half of the cases that expert reviewers believe physicians should lose and nearly all of the cases that experts feel physicians should win. Defendants and their hired experts, it turns out, are more successful than plaintiffs and their hired experts at persuading juries to reach verdicts contrary to the opinions of independent reviewers.

Expert Information And Expert Evidence: A Preliminary Taxonomy, Samuel R. Gross, Jennifer L. Mnookin

Articles

Federal Rule of Evidence 702 speaks in very general terms. It governs every situation in which "scientific, technical or other specialized knowledge will assist the trier of fact," and provides that, in that situation, "a witness qualified as an expert by knowledge, skill, experience, or education, may testify thereto in the form of an opinion or otherwise . . . .' In 2000, following a trio of Supreme Court cases interpreting Rule 702, the Rule was amended to include a third requirement, in addition to the helpfulness of the testimony and the qualifications of the witness: reliability. Under Rule 702 …

Discovery And Presentation Of Evidence In Adversary And Nonadversary Proceedings, E. Allan Lind, John Thibaut, Laurens Walker

Michigan Law Review

In order to evaluate fully the advantage claimed for the adversary model we sought to add a third element that would test the hypothesis under a variety of conditions. The degree to which the evidence discovered in a case favors one party at the expense of another appeared to meet this criterion. This fact-distribution element is a pervasive condition of legal conflict resolution that, intuition suggests, may significantly influence information search and transmission. Further, this variable could be easily and accurately controlled by regulating the flow of favorable information acquired by the subjects during the experiment.

Subjective Complaints V. Objective Signs, David I. Sindell, Irwin N. Perr

Cleveland State Law Review

The word "versus" in the title presents what we think is one of the most important problems of plaintiff trial lawyers today. After years of preparation, we submit our case to a jury; our medical witnesses offer testimony based on long time observation, treatment and evaluation. Then, in walks the defendant's doctor and proceeds to plunge a dagger into our case by calling our client either a malingerer or a neurotic, or just a plain liar. He testifies that he saw none of the objective signs that our medical examiners found, and concludes that all of the subjective complaints are …
