Since its inception, evidence policymakers have vacillated with respect to whether the rule barring hearsay evidence at trial is a doctrine designed to promote decisional accuracy or a doctrine designed to promote procedural justice.

To the extent that policymakers view the rule barring hearsay evidence as promoting decisional accuracy, the rationale for this view stems from the “testimonial triangle” promulgated by Professor Laurence Tribe, which conceptualizes the objections to hearsay evidence at common law. Tribe’s testimonial triangle states that (1) several infirmities lurk behind all testimony provided in court, and (2) testimony based on hearsay is subject to two sets …

Signal Vs. Noise: Some Comments On Professor Stein's Theory Of Evidential Efficiency, Emily Spottswood

Scholarly Publications

In this Essay, I examine Professor Stein's intriguing new theory of evidential efficiency, which posits that judges should admit evidence whenever it has a sufficiently high "signal-to-noise ratio." I explore a slightly different definition of the concepts of "signal" and "noise" than Stein, based upon likelihood ratio values rather than the underlying probabilities of events, and I explain why these altered concepts may be analytically superior. Additionally, I call into question the strength of the connection between the signal-to-noise ratio of a piece of evidence and the costs of admitting it at trial. Nevertheless, Stein's project is worthy of great …
