Reliability Of Expert Evidence In International Disputes, Matthew W. Swinehart Jan 2017

Reliability Of Expert Evidence In International Disputes, Matthew W. Swinehart

Michigan Journal of International Law

Part I of this article traces the historical trends in the use of expert evidence in international disputes, from the scattered reliance on experts in the nineteenth and early twentieth centuries to the ubiquity of experts in modern disputes. With that perspective, Part II examines how decision makers have attempted to ensure reliability of the expert evidence that is flooding the evidentiary records of international disputes, while Part III outlines the many problems that still remain. Finally, Part IV proposes a non-exhaustive and nonbinding checklist of questions for analyzing the reliability of any type of expert evidence.


The Cognitive Psychology Of Circumstantial Evidence, Kevin Jon Heller Nov 2006

The Cognitive Psychology Of Circumstantial Evidence, Kevin Jon Heller

Michigan Law Review

Empirical research indicates that jurors routinely undervalue circumstantial evidence (DNA, fingerprints, and the like) and overvalue direct evidence (eyewitness identifications and confessions) when making verdict choices, even though false-conviction statistics indicate that the former is normally more probative and more reliable than the latter The traditional explanation of this paradox, based on the probability-threshold model of jury decision-making, is that jurors simply do not understand circumstantial evidence and thus routinely underestimate its effect on the objective probability of the defendant's guilt. That may be true in some situations, but it fails to account for what is known in cognitive psychology …


Some Steps Between Attitudes And Verdicts, Phoebe C. Ellsworth Jan 2003

Some Steps Between Attitudes And Verdicts, Phoebe C. Ellsworth

Book Chapters

Most research that has attempted to predict verdict preferences on the basis of stable juror characteristics, such as attitudes and personality traits, has found that individual differences among jurors are not very useful predictors, accounting for only a small proportion of the variance in verdict choices. Some commentators have therefore concluded that verdicts are overwhelmingly accounted for by "the weight of the evidence," and that differences among jurors have negligible effects. But there is a paradox here: In most cases the weight of the evidence is insufficient to produce firstballot unanimity in the jury (Hans & Vidmar, 1986; Hastie, Penrod, …


When Balance And Fairness Collide: An Argument For Execution Impact Evidence In Capital Trials, Wayne A. Logan Dec 1999

When Balance And Fairness Collide: An Argument For Execution Impact Evidence In Capital Trials, Wayne A. Logan

University of Michigan Journal of Law Reform

A central precept of death penalty jurisprudence is that only the "death worthy" should be condemned, based on a "reasoned moral response" by the sentencing authority. Over the past decade, however, the Supreme Court has distanced itself from its painstaking efforts in the 1970s to calibrate death decision making in the name of fairness. Compelling proof of this shift is manifest in the Court's decisions to permit victim impact evidence in capital trials, and to allow jurors to be instructed that sympathy for capital defendants is not to influence capital decisions. This Article examines a novel strategy now being employed …
