The Incongruence Principle Of Evidence, Hillel Bavli

Faculty Journal Articles and Book Chapters

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 …

Big Data Analytics: What Can Go Wrong, Sharona Hoffman

Faculty Publications

It is not uncommon to read that long-held beliefs about medical treatments have been dislodged by new studies. For example, there is now doubt as to whether women should undergo annual mammograms, previously a cornerstone of cancer screening. Hormone replacement therapy for menopausal women, once considered highly suspect in light of worrisome research findings, is now being reconsidered as a beneficial therapy. These reversals trouble and confuse many Americans.

This Article explores why medical research findings can be erroneous and what can go wrong in the process of designing and conducting research studies. It provides readers with essential analytical tools …

Alternative Facts And The Post-Truth Society: Meeting The Challenge, S. I. Strong

Faculty Publications

In the hours following the 2017 U.S. presidential inauguration, the world was introduced to the concept of "alternative facts," a term that quickly became synonymous with a willingness to persevere with a particular belief either in complete ignorance of, or with a total disregard for, reality.' The increasing incidence of alternative facts in the popular and political arena creates a critical conundrum for lawyers, judges, legislators, and anyone interested in deliberative democracy, since it is unclear how rational debate can proceed if empirical evidence holds no persuasive value.

This Essay seeks to use empirical research to demonstrate that conventional means …

An Empirical Method For Harmless Error, Christopher Robertson

Faculty Scholarship

Trials are often imperfect. When inadmissible evidence is introduced or the jury is incorrectly instructed, judges must determine whether the error was prejudicial or merely harmless. In making that assessment, judges resort to speculation about the counterfactual question of whether the error changed the outcome, compared to the decision of a properly informed and instructed jury. These decisions are likely colored by confirmation and status quo biases, along with “mental contamination” of the error itself. Even when appellate judges perform these analyses accurately, their decisions appear conclusory. Scholars and judges have roundly criticized this doctrine, but no solution has emerged. …

Behavioral Economics: Implications For Regulatory Behavior, William E. Kovacic, James C. Cooper

GW Law Faculty Publications & Other Works

Behavioral economics (BE) examines the implications for decision-making when actors suffer from biases documented in the psychological literature. This article considers how such biases affect regulatory decisions. The article posits a simple model of a regulator who serves as an agent to a political overseer. The regulator chooses a policy that accounts for the rewards she receives from the political overseer — whose optimal policy is assumed to maximize short-run outputs that garner political support, rather than long-term welfare outcomes — and the weight the regulator puts on the optimal long run policy. Flawed heuristics and myopia are likely to …

False Convictions, Phoebe C. Ellsworth, Samuel R. Gross

Book Chapters

False convictions have received a lot of attention in recent years. Two-hundred and forty-one prisoners have been released after DNA testing has proved their innocence, and hundreds of others have been released without DNA evidence. We now know quite a bit more about false convictions than we did thirty years ago - but there is much more that we do not know, and may never know.

It’S Not About The Money: The Role Of Preferences, Cognitive Biases And Heuristics Among Professional Athletes, Michael Mccann

Law Faculty Scholarship

Professional athletes are often regarded as selfish, greedy, and out-of-touch with regular people. They hire agents who are vilified for negotiating employment contracts that occasionally yield compensation in excess of national gross domestic products. Professional athletes are thus commonly assumed to most value economic remuneration, rather than the love of the game or some other intangible, romanticized inclination.

Lending credibility to this intuition is the rational actor model, a law and economic precept which presupposes that when individuals are presented with a set of choices, they rationally weigh costs and benefits, and select the course of action that maximizes their …

The Reckless Pursuit Of Dominion: A Situational Analysis Of The Nba And Diminishing Player Autonomy, Michael Mccann

Law Faculty Scholarship

This Article examines required genetic testing of NBA players from a situational vantage point, integrating socio-psychological, legal, and ethical analyses. The core argument may be expressed as follows: required genetic testing of NBA players appears consistent with a broader and largely deleterious agenda by the NBA to control players. Since implementation of the rookie wage scale in 1995 through the recent imposition of a paternalistic player dress code, the NBA has increasingly usurped player autonomy. The NBA's capacity to do so largely rests in its adroit manipulation of the situational influences that influence fans and media. For instance, because of …

O.J. Simpson Verdict Raises Questions About Jury System, Aubrey Immelman

Psychology Faculty Publications

This opinion column examines whether conformity pressures, confirmation bias, and belief perseverance could have influenced jury deliberations and the verdict in The State of California v. O. J. Simpson.
