Can Jury Instructions Have an Impact on Trial Outcomes, California, 2018 (ICPSR 37956)
Released/updated on: 2023-04-13
Geographic coverage: United States, California
Time period: 2018-01-01--2018-12-31
This funded project tested whether "implicit bias" jury instructions can mitigate discrimination by juries. Implicit bias instructions are being used in a small but growing number of jurisdictions, but have not yet been adequately tested for efficacy. The study employed a 2 x 2 x 2 factorial design, in which the race of defendant (Black or White), race of informant witness (Black or White), and jury instructions (implicit bias or standard bias instruction) was varied, creating eight experimental conditions. The data in this archive represent 623 participants who were assigned to one of 120 jury groups who viewed a federal drug conspiracy trial, deliberated to a verdict, then completed a series of individual measures.

Evaluation of Hung Juries in Bronx County, New York, Los Angeles County, California, Maricopa County, Arizona, and Washington, DC, 2000-2001 (ICPSR 3689)
Released/updated on: 2006-03-30
Geographic coverage: United States, Washington, DC, California, New York (state), Arizona
Time period: 2000-01-01--2001-01-01
This study was undertaken for the purpose of providing an empirical picture of hung juries. Researchers were able to secure the cooperation of four courts: (1) Bronx County Supreme Court in New York, (2) Los Angeles County Superior Court in California, (3) Maricopa County Superior Court in Arizona, and (4) District of Columbia Superior Court in Washington, DC. The four sites were responsible for distributing and collecting questionnaire packets to all courtrooms hearing non-capital felony jury cases. Each packet contained a case data form requesting information about case characteristics (Part 1) and outcomes (Part 2), as well as survey questionnaires for the judges (Part 3), attorneys (Part 4), and jurors (Part 5). The case data form requested type of charge, sentence range, jury's decision, demographic information about the defendant(s) and the victim(s), voir dire (jury selection process), trial evidence and procedures, and jury deliberations. The judge questionnaire probed for evaluation of the evidence, case complexity, attorney skill, likelihood that the jury would hang, reaction to the verdict, opinions regarding the hung jury rate in the jurisdiction, and experience on the bench. The attorney questionnaire requested information assessing the voir dire, case complexity, attorney skill, evaluation of the evidence, reaction to the verdict, opinions regarding the hung jury rate in the jurisdiction, and experience in legal practice. If the jury hung, attorneys also provided their views about why the jury was unable to reach a verdict. Finally, the juror questionnaire requested responses regarding case complexity, attorney skill, evaluation of the evidence, formation of opinions, dynamics of the deliberations including the first and final votes, juror participation, conflict, reaction to the verdict, opinions about applicable law, assessment of criminal justice in the community, and demographic information.

Jury Verdicts Database for Cook County, Illinois, and All Counties in California, 1960-1984 (ICPSR 6232)
Released/updated on: 2006-01-12
Geographic coverage: United States, Chicago, Illinois
This data collection contains information on jury verdict civil cases in Cook County, Illinois, and all counties in California. The RAND Corporation's Institute for Criminal Justice began this study in the early 1980s in response to widespread public interest in the magnitude of dollar verdicts returned in civil cases. The goal was to record salient information found in court reporter publications to allow for a wide range of future research. Two such publications were chosen because of their favorable reputations and because they both dated back to 1960: the "Cook County Jury Verdict Reporter" of Chicago, Illinois, and "Jury Verdicts Weekly" of Santa Rosa, California. The collection of data for this study was conducted in two phases. Phase I included cases from 1960-1979, and Phase II coded cases from 1980-1984, including a small number of cases from 1985. In both phases, only cases in which a jury reached a definitive outcome (including deadlocked or hung juries) were included. In Phase I, only San Francisco County cases from the California reporter publication were included. In Phase II, all California counties were included. For all cases in Phase I, a Main Form was completed that included jurisdiction, court type, dates of incidents and trial, information about parties involved, trial occurrences, outcome of trial, awards, and fees. In addition to this Main Form, at least one of nine different case-type forms was completed: Common Carrier-Passenger Form, Dram Shop Form, Injuries on Property/Attractive Nuisance Form, Malpractice Form, Miscellaneous Form, Products Liability Form, Street Hazards/Highway Construction Form, Traffic/Pedestrian/Rider Form, and Work Injuries and FELA Form. These forms contained questions regarding the behavior of each party in the case and other characteristics and facts relevant to the case. A Jury Verdicts Form was completed for all cases in Phase II. This form picked up general case-level and defendant-specific data such as dates and length of trial, case outcome, original number of parties involved, and collapsing of multiple defendants into one case. For each plaintiff, a Plaintiff Information Form was filled out containing general plaintiff information such as losses claimed and the coder's assessment of the degree of the plaintiff's comparative negligence. This form also indicated which of the loss forms was coded for this plaintiff (only one loss form was completed for each plaintiff): Death Action, Personal Injuries, or Money Damages. Each form contained basic information about the outcome of the case, specific damages claimed by the plaintiff, and loss-specific data. Additionally, an Ancillary Action Form was completed for any associated claims that were adjudicated at the time of the main case, such as counter-suits by defendants. The questions on this form were the same as those on the main Jury Verdicts Form. Finally, this study includes an Integrated Jury Verdicts Database (Part 33) containing data from both phases to permit easier analysis of data from all years. This database contains five sections: (1) the basic trial information, which includes the trial dates and lengths, reporter source, and jurisdiction, (2) the main case information, which includes more detailed data about the case such as number of parties involved, case type, types of losses claimed, and total compensatory and punitive awards, (3) information about the first ancillary action, (4) information about the second ancillary action, and (5) a listing of all the forms used.

The Multnomah County, Oregon, Jury Project was conducted as part of the Modeling Jury Decision Project funded by the National Science Foundation. These data represent a census of 32 jury panels that served from July 1973 through March 1976 in the Fourth Circuit Court in Multnomah County (Portland), Oregon. Information was obtained for both six-member and twelve-member juries. Data were collected from official court records, monthly juror panel summaries, and self-administered juror demographic data sheets. Information collected includes members of the jury, their votes, the final verdict, the type of case, the name of the judge, and the amount of time taken by the jury to arrive at a decision, as well as each juror's age, occupation, years of residence in Oregon, educational background, family information, and information on past juries and trials they were involved in.

Police Documentation of Drunk Driving Arrests, 1984-1987: Los Angeles, Denver, and Boston (ICPSR 9400)
Released/updated on: 2005-11-04
Geographic coverage: United States, Massachusetts, Colorado, Los Angeles, Denver, California, Boston
Time period: 1984-01-01--1987-01-01
These data measure the effects of blood alcohol content coupled with officer reports at the time of arrest on driving while intoxicated (DWI) case outcomes (jury verdicts and guilty pleas). Court records and relevant police reports for drunk-driving cases drawn from the greater metropolitan areas of Boston, Denver, and Los Angeles were compiled to produce this data collection. Cases were selected to include roughly equal proportions of guilty pleas, guilty verdicts, and not-guilty verdicts. DWI cases were compared on the quality and quantity of evidence concerning the suspect's behavior, with the evidence coming from any mention of 20 standard visual detection cues prior to the stop, 13 attributes of general appearance and behavior immediately after the stop, and the results of as many as 7 field sobriety tests. Questions concerned driving-under-the-influence cues (scoring sheet), observed traffic violations and actual traffic accidents, the verdict, DWI history, whether the stop resulted from an accident, whether the attorney was public or private, and sanctions that followed the verdict. Also included were demographic questions on age, sex, and ethnicity.
