'False But Highly Persuasive:' How Wrong Were The Probability Estimates In Mcdaniel V. Brown?, David H. Kaye

In McDaniel v. Brown, the Supreme Court will review the use of DNA evidence in a 1994 trial for sexual assault and attempted murder. The Court granted certiorari to consider two procedural issues - the standard of federal postconviction review of a state jury verdict for sufficiency of the evidence, and the district court's decision to allow the prisoner to supplement the record of trials, appeals, and state postconviction proceedings with a geneticist's letter twelve years after the trial.
This essay clarifies the nature and extent of the errors in the presentation of the DNA evidence in Brown. It questions …

Visualizing Dna Proof, Nicholas L. Georgakopoulos

DNA proof inherently involves the use of probability theory, which is often counterintuitive. Visual depictions of probability theory, however, can clarify the analysis and make it tractable. A DNA hit from a large database is a notoriously difficult probability theory issue, yet the visuals should enable courts and juries to handle it. The Puckett facts are an example of a general approach: A search in a large DNA database produces a hit for a cold crime from 1972 San Francisco. Probability theory allows us to process the probabilities that someone else in the database, someone not in the database, or …

This article describes parts of an unusually realistic experiment on the comprehension of expert testimony on mitochondrial DNA (mtDNA) sequencing in a criminal trial for robbery. Specifically, we examine how jurors who responded to summonses for jury duty evaluated portions of videotaped testimony involving probabilities and statistics. Although some jurors showed susceptibility to classic fallacies in interpreting conditional probabilities, the jurors as a whole were not overwhelmed by a 99.98% exclusion probability that the prosecution presented. Cognitive errors favoring the defense were more prevalent than ones favoring the prosecution. These findings lend scant support to the legal argument that mtDNA …

In 1946, public outrage erupted after a jury ordered Charlie Chaplin to support a child who, according to apparently definitive blood tests, was not his. Half a century later, juries have again defied apparently definitive evidence of innocence, finding criminal defendants guilty based on a confession or eyewitness notwithstanding exculpatory DNA test results. One might expect judges in such cases to direct an acquittal, on grounds that the evidence is legally insufficient because no rational juror could find guilt beyond a reasonable doubt. Yet few if any do. Instead, courts defer to juries when they form an actual belief in …
