The Persistence Of The Probabilistic Perspective, Richard D. Friedman
The Persistence Of The Probabilistic Perspective, Richard D. Friedman
Articles
The publication now of an essay written by Craig Callen nearly a decade ago is cause for wistful celebration. Even while we are reminded how suddenly and prematurely Craig’s life ended, it is good to have one more academic contribution from him, especially because it is marked by the erudition, thoroughness, gentleness, and humor that characterized him.
A Very Brief Primer On Bayesian Methods In Evidence, Richard D. Friedman
A Very Brief Primer On Bayesian Methods In Evidence, Richard D. Friedman
Articles
I have been asked to write an extremely short explanation of the Bayesian approach to evidentiary issues, for the benefit of those who regard themselves as probabilistically challenged. Although the application of Bayesian probability to evidence has generated a good deal of debate, its use as a heuristic device should not be particularly controversial. Evidence concerns propositions that are uncertain. Accordingly, some concept of probability must play a role. Standards of persuasion, such as "more likely than not" and "beyond a reasonable doubt" are clearly probabilistic, and the definition of relevant evidence, as expressed in Fed. R. Evid. 40 I, …
A Suggestion On Suggestion, Richard D. Friedman, Stephen J. Ceci
A Suggestion On Suggestion, Richard D. Friedman, Stephen J. Ceci
Articles
Part I of the full article briefly describes the history and current slate of research into children's suggestibility. In this part, we argue that, although psychological researchers disagree considerably over the degree to which he suggestibility of young children may lead to false allegations of sexual abuse, there is an overwhelming consensus that children are suggestible to a degree that, we believe, must be regarded as significant. In presenting this argument, we respond to the contentions of revisionist scholars, particularly those recently expressed by Professor Lyon. We show that there is good reason to believe the use of highly suggestive …
The Suggestibility Of Children: Scientific Research And Legal Implications, Stephen J. Ceci, Richard D. Friedman
The Suggestibility Of Children: Scientific Research And Legal Implications, Stephen J. Ceci, Richard D. Friedman
Articles
In this Article, Professors Ceci and Friedman analyze psychological studies on children's suggestibility and find a broad consensus that young children are suggestible to a significant degree. Studies confirm that interviewers commonly use suggestive interviewing techniques that exacerbate this suggestibility, creating a significant risk in some forensic contexts-notably but not exclusively those of suspected child abuse-that children will make false assertions of fact. Professors Ceci and Friedman address the implications of this difficulty for the legal system and respond to Professor Lyon's criticism of this view recently articulated in the Cornell Law Review. Using Bayesian probability theory, Professors Ceci and …
Towards A (Bayesian) Convergence?, Richard D. Friedman
Towards A (Bayesian) Convergence?, Richard D. Friedman
Articles
If I understand them correctly, several leading Bayesioskeptics (Allen, Callen, Stein) acknowledge - with varying degrees of specificity and varying degrees of grudgingness - that standard probability theory can be useful as an analytical tool in considering evidentiary doctrines and the probative value of evidentiary items.
Irrelevance, Minimal Relevance, And Meta-Relevance (Response To David Crump), Richard D. Friedman
Irrelevance, Minimal Relevance, And Meta-Relevance (Response To David Crump), Richard D. Friedman
Articles
Professor Crump's analysis runs the full traverse from academic theorizing to practical observation. I will attempt to follow him over the same course, addressing three questions among the congeries that he raises. First, is it true that all evidence satisfies the minimalist definition of relevance? Second, should evidentiary codes include a tighter definition of relevance? Third, how should we assess lawyers' use of evidence that, loosely speaking, is irrelevant?
Answering The Bayesioskeptical Challenge, Richard D. Friedman
Answering The Bayesioskeptical Challenge, Richard D. Friedman
Articles
In recent years, some scholars of evidence, myself among them, have made active use of subjective probability theory - what is sometimes referred to as Bayesianism - in thinking about issues and problems related to the law of evidence. But, at the same time, this use has been challenged to various degrees and in various ways by scholars to whom I shall apply the collective, if somewhat misleading, label of Bayesioskeptics. I present this brief paper to defend this use of probability theory, and to discuss what I believe is its proper role in discourse about evidentiary issues.

Probability And Proof In State V. Skipper: An Internet Exchange, Ronald J. Allen, David J. Balding, Peter Donnelly, Richard D. Friedman, David H. Kaye, Lewis Henry Larue, Roger C. Park, Bernard Robertson, Alexander Stein
Articles
This is not a conventional article. It is an edited version of messages sent to an Internet discussion list. The listings begin with the mention of a recent opinion of the Connecticut Supreme Court, parts of which are reproduced below. The listings soon move to broader issues concerning probability and other formal systems, their limitations, and their uses either in court or as devices for understanding legal proof.
Conditional Probative Value: Neoclassicism Without Myth, Richard D. Friedman
Conditional Probative Value: Neoclassicism Without Myth, Richard D. Friedman
Articles
The concept of conditional relevance is an essential aspect of the classical model of evidentiary law. Some of the great scholars of evidence have endorsed and shaped it.1 Under Federal Rule of Evidence 104(b) it plays a crucial role in the division of responsibility between judge and jury,2 as well as in the application of the personal knowledge3 and authentication 4 requirements. And the Supreme Court has applied it with great force.5 In recent years, though, the concept has come under attack from several notable scholars. The late Vaughn Ball led the assault, calling the concept a "myth."'6 Peter Tillers, …
Character Impeachment Evidence: The Asymmetrical Interaction Between Personality And Situation, Richard D. Friedman
Character Impeachment Evidence: The Asymmetrical Interaction Between Personality And Situation, Richard D. Friedman
Articles
In Part I of this Comment, I present a short version of my argument against the admissibility of character impeachment evidence of criminal defendants, showing how the key elements ofthis argument are present in Professor Uviller's own Article. In Part II, I suggest that, notwithstanding Professor Uviller's comments to the contrary, an asymmetrical result-never admitting character evidence to impeach criminal defendants but admitting such evidence in some circumstances to impeach other witnesses- is perfectly reasonable. Finally, in Part III, I contend that Professor Uviller's interesting judicial surveys support the solution I have proposed for the problem of character impeachment evidence.

Character Impeachment Evidence: Psycho-Bayesian (!?) Analysis And A Proposed Overhaul, Richard D. Friedman
Character Impeachment Evidence: Psycho-Bayesian (!?) Analysis And A Proposed Overhaul, Richard D. Friedman
Articles
Typically, arguments for restricting character impeachment evidence are based in part on the premise that prior crimes, at least violent crimes, generally indicate little about a person's veracity. The argument advanced here against character impeachment of criminal defendants does not rely on that premise; in fact, it accepts the premise that prior antisocial behavior, even not involving dishonesty, often does indicate a good deal about a person's general truthtelling inclination. A careful analysis of the situation of the accused on the witness stand-rather than an easy assumption about irrelevance-leads to this Article's broad conclusion that character impeachment evidence of criminal …
