16 The tone toward the researchers was decidedly hostile.

McCarthy-era red baiting was evident. Subcommittee members implied that radical tendencies might have motivated the jury bugging. Kalven, for example, was asked about his agreement with statements about juries from Vishinsky's Law of the Soviet State (id. at 90), whether or not he read the radical paper Daily Worker (id. at 86), and whether he had written a letter to President Truman requesting clemency for the Rosenbergs who were convicted and executed for spying (id. at 86). Hans Zeisel expressed to us his pride in Kalven's steadfastness at the hearing (interview, cited in authors' note).Google Scholar

20 Judges also reported on civil trials. There were plans to undertake a companion volume on civil juries; and at least some analysis of the civil jury data was performed (at 63–65; see also Harry Kalven, Jr., “The Dignity of the Civil Jury,” 50 U. Va. L. Rev. 1055 (1964)), but the data have never been fully reported. In our interview, Zeisel said that he was “heartbroken” about this failure. Despite a number of efforts, various factors, including a lost codebook when another attempt at data analysis was undertaken many years later, interfered with completion of the civil jury work (interview, cited in authors' note).CrossRefGoogle Scholar

21 The figures varied slightly from table to table in the book depending on how the data from hung juries were treated.Google Scholar

22 The book was reviewed in 17 American, 1 Canadian, and 3 British law reviews and in major social science journals. Interestingly, in light of the subsequent high frequency of citation among psychologists, it was never reviewed in Contemporary Psychology, a professional periodical reviewing books pertinent to psychology. Reviews also appeared in popular magazines such as the New Yorker, Scientific American, and Saturday Review. Google Scholar

While we have highlighted scholarly reviews offering the harshest criticism of the work, the reader should be aware that the book did receive some generally positive reviews: e.g., D.

He noted that the first version of the questionnaire simply asked the judge to indicate whether the trial lawyers were experienced, whereas the second asked how well the case was tried. While the former question did not assess superiority, both were combined for the data analysis. Furthermore, Kaplan observed that since the instructions did not specify that the lawyer evaluation was to be made prior to the jury verdict, judges may have based their judgments of lawyer superiority on case outcomes.Google Scholar

42 Two British researchers undertook a statistical critique of sample biases and other problems in The American Jury. A. E. Bottoms & Monica A. Walker, “The American Jury: A Critique,” 67 J. Am. Statistical A. 773 (1972). Bottoms and Walker showed that there was a statistically significant under representation of cases from the South–a fact that Kalven and Zeisel had conceded. Bottoms and Walker also demonstrated that the acquittal rates for certain crimes in Kalven and Zeisel's sample significantly differed from census figures and pointed out possible discrepancies between the 1954 and 1958 data sets.CrossRefGoogle Scholar

Kalven and Zeisel offered a brief response. Harry Kalven, Jr., & Hans Zeisel, “Rejoinder,” 67 J. Am. Statistical A. 779 (1972). The rejoinder noted that the book already acknowledged most differences shown by Bottoms and Walker's statistical analyses, and that other data ignored by Bottoms and Walker were consistent with the book's conclusions. The rejoinder reminded readers once again that The American Jury's methodology was an attempt to deal with imperfect data, observing that Bottoms and Walker's critique had a “virginal tone that smacks of experience too limited to textbook methodology.”Id. at 779.Google Scholar

43 As an example of a debatable assumption, Kalven and Zeisel argued that criticism about the judge's hypothetical verdict was partially nullified by the fact that the verdict is one that judges make routinely, increasing the probability that the simulated verdict would be similar to the real verdict. This does not necessarily follow, particularly if judges, aware that they were participating in a research study, attempted to anticipate the jury's decision.Google Scholar

44 Zeisel acknowledged during our interview that “we were generous to our data” (interview, cited in authors' note).

Yet Kalven and Zeisel maintained that the comparison should not be viewed this way: “Our purpose was not to evaluate but only to find out as carefully as we could how the jury actually performs” (at 498–99).Google Scholar

As an interesting footnote to history, Burger was Assistant Attorney General at the time of the Senate Subcommittee hearings about the Wichita jury bugging incident. Subcommittee Chair Eastland quoted from a news article describing a speech Burger made about the incident during Kalven's testimony at the hearing: “A Justice Department official charged today that the University of Chicago Law School plans to eavesdrop on 500 to a thousand juries during its research project into the American jury system. The planting of the microphone in Wichita, Kans., jury room was only the first step in a study of ‘very sweeping proposals.’” Kalven replied that the statement was false and asserted that “[t]he Department of Justice has good reason to know what the facts are.” J.

66 The findings on victim character were not strong; they reached statistical significance only when data from two separate studies (and 377 subjects) were standardized and combined. Landy & Aronson, 5 J. Experimental Soc. Psychology at 150. The authors were aware of Kalven and Zeisel's finding that defendant character influenced judge-jury disagreements when the evidence was ambiguous rather than clear (cf. their detailed discussion at 146) but did not incorporate the insight into their design. Instead, Landy and Aronson used a case in which guilt was crystal clear.Google Scholar

67 Id. at 151–52. Their results could just as easily be read as contradicting Kalven and Zeisel, who concluded that defendant and victim attractiveness influenced judge-jury disagreement primarily in cases with ambiguous evidence. Also problematic is the parallel drawn between sentencing and guilt judgments.Google Scholar

68 Weiten and Diamond documented the “spectacular” increase by counting the number of published and unpublished papers reporting jury simulations from 1964 to 1975. From 1964 to 1966, there were 7 studies; 1967–69, 14 studies; 1970–72, 25 studies; and 1973–75, 62 studies. Wayne Weiten & Shari S. Diamond, “A Critical Review of the Jury Simulation Paradigm: The Case of Defendant Characteristics,” 3 Law & Hum. Behav. 71, 72–73 (1979)Google Scholar

Our own citation count also showed a dramatic increase in social science references to The American Jury. We divided the citations into those from law journals and those from social science journals. Journals devoted to social scientific study of law, such as Law and Hum. Behavior and Law & Society Review, were categorized as social science journals. Table 1 shows that social science journal citations moved from a low of 15% of all citations in 1966–70 to a high of 55% in 1981–85.Google Scholar

72 One study, for example, presented a lengthy videotaped trial stimulus to subjects from juror rolls, varying the legally relevant factor of jury decision rule. Reid Hastie, Steven D. Penrod, & Nancy Pennington, Inside the Jury (Cambridge, Mass.: Harvard, 1983) (“Hastie et al., Inside the Jury”). Other jury researchers began to explore legally important variables such as the jury's size and the impact of death-qualification in jury selection. By 1982 Diamond concluded that the improvements in jury simulation methodology were evidencethat the field of psychology and law was maturing. Diamond, Shari S., “Growth and Maturation in Psychology and Law“, Law & Soc'y Rev. 17 11 (1982).CrossRefGoogle Scholar

Interestingly, however, a review of articles bearing on juries published in Law and Human Behavior from 1986 to 1990 showed that one of the most frequent references to The American Jury pertained to the finding that jury verdicts can be predicted by the distribution of the individual members' predeliberation verdicts. Typically, this finding was cited to justify using individuals rather than groups in mock juror studies.Google Scholar

73 Table 1 shows that in the most recent period of citations, social science journals accounted for 43% of all citations to the work. This probably understates the impact of The American Jury on contemporary social science research, because law reviews have increasingly published both original research and reviews of research.Google Scholar

76 Our selection included books containing substantive treatment of the institution of the jury and jury research. We excluded edited books and “how-to” books by jury consultants. The collection of books on the jury is not exhaustive, nor was it meant to be. Rather, we attempted to analyze a reasonable selection of the jury book literature to determine how The American Jury was presented. The books included John Baldwin & Michael McConville, Jury Trials (Oxford: Clarendon Press, 1979) (“Baldwin & McConville, Jury Trials”); Paula DiPerna, Juries on Trial: Faces of American Justice (New York: Dembner Books, 1984) (“DiPerna, Juries”); Hubert S.

78 Hastie et al., Inside the Jury, and Saks, Jury Verdicts, primarily cited The American Jury for findings that were directly relevant to their studies of jury size and decision rule. Many of the citations in Hastie et al. related to hung jury rates in unanimous and majority decision rule groups. Both Saks and Hastie et al. mentioned the relationship between first-ballot votes and final jury verdicts, especially as it pertained to individuals deadlocking the jury.Google Scholar

Guinther, Jury, whose book reported questionnaire data about the civil jury, cited the broader findings of The American Jury. Google Scholar

Selvin & Picus's Debate analyzed an asbestos jury's decision making and cited The American Jury only a handful of times, observing that its method of judge-jury agreement was of limited value in evaluating the jury's performance in a specific trial such as the asbestos case under consideration.Google Scholar

Feild and Bienen's Jurors and Rape cited The American Jury primarily for findings related to rape cases, although they also cited it as a source showing the impact of criminal record (at 96) and lawyer prestige (at 97) on juror judgments. They noted that although Kalven and Zeisel are usually cited for the proposition that juries won't convict in rape cases where judges would, the study was dated and judges were probably not free of bias in rape cases (at 204–5).Google Scholar

79 Most accounts of the methodology were not extensive. Hans & Vidmar, Judging the Jury at 116; Kassin & Wrightsman, American Jury 16; and Simon, The Jury at 49 had the most elaborate descriptions of the Jury Project's methods.

82 Id. at 8. Our reading of the book review literature is obviously quite different.

But Baldwin & McConville, Jury Trials 12 (footnote omitted), maintained that “to say that judges agree with the verdicts of juries in three-quarters of all cases does not mean that the juries in question must have reached the right verdict in these cases or even that (as Kalven and Zeisel infer from their data) the jury must have understood and followed the evidence. Perhaps the judge and jury reached their decisions in completely different ways, agreeing only in the result.”Google Scholar

99 The most serious misinterpretation occurred in Williams v. Florida, 399 U.S. 78 (1970). In that jury size case, the Supreme Court cited The American Jury to argue that jurors in the minority on the first ballot are likely to be influenced by the proportional rather than the absolute size of the majority faction. Yet in one of the cited passages, Kalven and Zeisel wrote about the importance of a minority member on the jury having at least one initial ally. Therefore the absolute sizes of minority and majority factions are critical. A jury split 10–2 is not the functional equivalent of a jury split 5–1, contrary to the Court's assertion. See Michael J. Saks, “Ignorance of Science is No Excuse,” 10 Trial 18 (1974).Google Scholar

In a few other instances, the implications the court drew from the findings were questionable. Consider the Court's pronouncement in Spencer v. Texas:“[T]he most recent scholarly study of jury behavior does not sustain the premise that juries are especially prone to prejudice when prior-crime evidence is admitted as to credibility. The study contrasts the effect of such evidence on judges and juries and concludes that ‘Neither the one nor the other can be said to be distinctively gullible or skeptical.’“385 U.S. 554, 565 n.8 (1967).

104 Despite an abundant crop of jury simulation studies, studies of actual jury cases remain rare. Although British researchers Baldwin and McConville attempted a partial replication and extension of the Kalven and Zeisel study, they encountered significant difficulties. Study of the verdicts of actual juries appears to be increasing: the Federal Judicial Center, the RAND Corporation, the American Bar Foundation, and individual investigators have all examined jury verdicts in recent work.Google Scholar

It is interesting to speculate about why there have not been more efforts to replicate and extend Kalven and Zeisel's classic study of judge-jury agreement. The time, energy, financial resources, and coordination required for a similar national study of jury decision making would be considerable. The methodological difficulties that confronted Kalven and Zeisel would also challenge other researchers. Furthermore, a large, multi-investigator project involving field research is at odds with the typical research strategies of many jury researchers. Often trained as social psychologists, they tend to prefer laboratory simulation research and work as single investigators. Finally there is the limited cachet of replicating a well-known study.Google Scholar

105 Hans & Vidmar, Judging the Jury 47–61 (cited in note 53). The Jury Selection and Service Act of 1968 requires selection of federal jury panels from voters' lists; many states follow the same practice. Court decisions and technical improvements, such as the use of computerized records and multiple source lists, have further increased the representativeness of the jury.Google Scholar

106 In a discussion of jury prejudice, Hans and Vidmar discuss how more representative juries might increase judge-jury disagreement. In a case involving minority members, a jury containing minorities could explain to other jurors the meaning and implications of words and actions by the participants, thus increasing the competence of the jury compared to a white middle-class judge: “The jury would have insights about the meaning of the evidence that were beyond the knowledge of the judge. The judge would, therefore, favor one verdict and the jury another—and the jury would be correct.” Hans &. Vidmar, Judging the Jury 142.Google Scholar

116 As Kalven and Zeisel noted: We aspired to deal with imperfect data, obtained at great cost and in the teeth of formidable difficulties. Ours was a study of a large and unknown territory. Somewhat romantically seen, it was not unlike a first expedition to the bottom of the sea. There is only one way to advance our knowledge and to correct whatever wrong conclusions we may have reached: another expedition that will bring new data from the depths.Google Scholar
