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 …

The American Jury At Twenty-Five Years, Valerie P. Hans, Neil Vidmar

Cornell Law Faculty Publications

The year 1991 marks the twenty-fifth anniversary of the publication of Harry Kalven, Jr. and Hans Zeisel's classic work, The American Jury. Arguably one of the most important books in the field of law and social science, this research monograph began the modrn field of jury studies and deeply influenced contemporary understanding of the jury as an institution.

In this essay we assess the book from the vantage point of a quarter- century. First, we provide a historical backdrop by reviewing the activities of the University of Chicago's Jury Project that led to the publication of The American Jury …

Social Science And The Courts: The Role Of Amicus Curiae Briefs, Ronald G. Roesch, Stephen L. Golding, Valerie P. Hans, N. Dickon Reppucci

Cornell Law Faculty Publications

Social scientists have increasingly become involved in the submission of amicus curiae or "friend of the court" briefs in legal cases being decided by state and federal courts. This increase has triggered considerable debate about the use of briefs to communicate relevant social science research. This article evaluates the strengths and weaknesses of various methods of summarizing social science research for the courts. It also reviews the procedures for submitting briefs developed by the American Psychology-Law Society which, in collaboration with the American Psychological Association, has submitted its first brief in Maryland v. Craig, a case recently decided by …

Procedure's Magical Number Three: Psychological Bases For Standards Of Decision, Kevin M. Clermont

Cornell Law Faculty Publications

So many procedural doctrines appear, after research and teaching, to trifurcate. An obvious example is that kind of standard of decision known as the standard of proof: what in theory might have been a continuum of standards divides in practice into the three distinct standards of preponderance of the evidence, clear and convincing evidence, and proof beyond a reasonable doubt. Other examples suggest both that I am not imagining the prominence of three and that more than coincidence is at work.

Part I of this essay describes the role of the number three in procedure, with particular regard to standards …

Section 12 Of The Canada Evidence Act And The Deliberations Of Simulated Juries, Valerie P. Hans, Anthony N. Doob

Cornell Law Faculty Publications

In the past, there have been three major approaches to the experimental investigation of the jury. First, juror selection research involves the study of the relation between verdicts or leniency toward certain classes of defendants and the characteristics of potential jurors. The second class of research is group study, in which the amount and style of individual participation is observed within the context of simulated jury deliberations (e.g., Strodtbeck, James and Hawkins, 1957). Finally, experimental psychology has made another contribution to the study of the jury; numerous researchers have conducted experimental studies employing legal stimulus materials. Typically, in such a …
