Pre-trial publicity (PTP) related to a case often is both sided and slanted, emphasizing primarily negative information in an unbalanced manner about either the defendant or the injured party. Ruva and Guenther (2017) examined how juries made up of jurors exposed to various types of negative pre-trial publicity differ in their deliberations and decision-making from juries comprised of jurors exposed either to no PTP or only one type of PTP....

Evidence can be presented to jurors both verbally and visually, and if visual, as either an illustrative or substantative demonstrative. A substantive demonstrative has independent probative force, providing independent proof of a fact at issue in the case. Illustrative aids give visual form to other evidence, but provide no independent proof of that other evidence. Park and Feigenson (2021) conducted three studies that examined the effects of demonstrative evidence on mock jurors' pain and suffering damage awards....

Beliefs about what qualifies as sexual harassment matter to how judges and juries make decisions in sexual harassment cases.Rotundo, Nguyen and Sackett (2001) found in a meta-analysis of 62 research studies including over 33,000 participants that....

Multiple witnesses often observe an incident and, on average, 86% engage in post-event discussion with their co-witnesses (Paterson and Kemp, 2006). Witness communication can contaminate the memories of co-witnesses. Information suggested by one witness becomes, over time, part of other witnesses' memories and the other witnesses then remember seeing information which they only heard from another eyewitness. Co-witness communication leads to conformity in memories across witnesses....Garry and colleagues (2008) investigated co-witness suggestibility by having pairs of participants sit together and watch a crime video....

Hindsight bias is the tendency to overestimate the foreseeability of an outcome once the outcome is known. The hindsight bias is pervasive in decision-making, including juror decision-making. Research finds, for example, that jurors overestimate the likelihood of how foreseeable....

Journalists rely on eyewitnesses for many important details in news reports of legal cases. Reporters ask eyewitnesses questions and publish news reports of information that both includes and goes beyond what eyewitnesses say. Eyewitnesses both questioned and not questioned by reporters are exposed to the published news reports. Blom and Huang (2021) conducted three studies investigating whether news reporters taint eyewitness memories either directly through misleading questions to eyewitnesses or indirectly by publishing information that eyewitnesses then encounter....

False confessions are not rare. The National Registrar of Exonerations has reported that of the 2,400 exonerees in their database, 292 (12 percent) had falsely confessed. The Innocence Project has helped exonerate 375 individuals incarcerated for murders and rapes through post-conviction DNA testing, of whom 28 percent falsely confessed. False confessions also are powerfully persuasive evidence of guilt. False confessions are potent even when the interrogation is coercive, the decision-makers are trial judges, the confessors are juveniles, the confessions are reported secondhand by a motivated informant, and the confessions are contradicted by DNA and other evidence (see, for review, Rizzelli

Judges are increasingly using implicit bias instructions in jury trials. Implicit bias instructions are meant to educate jurors, transform what is implicit or unconscious into something recognizable to jurors, and steer jurors away from relying on implicit biases when considering evidence and making judgments. Lynch and colleagues (2022) explored the effect of an implicit bias instruction (warning about unconscious bias) versus a standard explicit bias instruction (warning about the need to avoid prejudice) in the context of possible racial bias in a mock trial study involving over 600 mock jurors....

Jurors exist in a day-to-day world consisting primarily of visual presentations of information, a world that eschews purely verbal presentations of information. A courtroom trial exists is a very different world, a world that often emphasizes the verbal and oral over the visual and technological. Between 2011 and 2017, a federal district judge in the Northern District of Illinois, Honorable Amy St. Eve, asked over 500 jurors in some 50 civil and criminal trials to complete a voluntary, anonymous questionnaire at the conclusion of their jury service (St. Eve & Scavo, 2018; St. Eve, 2021). Jurors were asked five questions,

Jurors do not experience a criminal trial as neutral blank slates. Jurors come to the trial with pre-existing attitudes and beliefs about many issues, including about the legal system. Social science researchers have used the Pre-Trial Juror Attitude Questionnaire (PJAQ) to measure a juror legal attitudes in criminal cases (Lecci & Myer, 2008). The PJAQ asks people to agree or disagree with statements that address their conviction proneness, confidence in the legal system, views of innate criminality, cynicism towards the defense, social justice and racial bias. People agreeing with many PJAQ statements have harsher attitudes toward criminal defendants. Statements on
