Faced with the problems of insufficient evidence, of conflicting evidence, and of evidence relayed through the flawed perceptual, retentive, and narrative abilities of witnesses, a jury is forced to draw inferences in its attempt to ascertain the truth. By applying the same cognitive tools they have developed and used over a lifetime, jurors engage in the inferential exercise that lawyers call fact-finding. In certain decision-making contexts that are relevant to the trial of lawsuits, however, these normally reliable cognitive tools may cause jurors to commit inferential errors that distort rather than reveal the truth.
Although juries can make a variety of inferential errors, most of these mistakes in judgment involve the drawing of an unwarranted conclusion from the evidence, that is, in reality, it does not prove. For example, evidence that the defendant in a criminal prosecution has a prior conviction may encourage jurors to presume the defendant’s guilt, because of their preconception that a person previously convicted of a crime must be inclined toward repeated criminal behavior. That commonly held belief is at least a partial distortion of reality; not all former convicts engage in repeated criminal behavior. Also, a jury may give more probative weight than objective analysis would allow to vivid photographic evidence depicting a shooting victim’s wounds, or may underestimate the weight of defense testimony that is not delivered in a sufficiently forceful or persuasive manner. Finally, complex or voluminous evidence might be so confusing to a jury that its members would draw totally unwarranted conclusions or even ignore the evidence entirely.
Recent empirical research in cognitive psychology suggests that people tend to commit inferential errors like these under certain predictable circumstances. By examining the available information, the situation, and the type of decision being made, cognitive psychologists can describe the kinds of inferential errors a person or a group is likely to make. These patterns of human decision-making may provide the courts with a guide to evaluating the effect of evidence on the reliability of the jury’s inferential processes in certain situations.
The fact that juries can commit inferential errors that jeopardize the accuracy of the fact-finding process is not unknown to the courts. In fact, one of a presiding judge’s duties is to minimize jury inferential error through explanation and clarification. Nonetheless, most judges now employ only a limited and primitive concept of jury inferential error: limited because it fails to recognize the potential for errors outside certain traditional situations, primitive because it ignores the research and conclusions of psychologists in favor of notions about human cognition held by lawyers.
1 . Which of the following best explains the main idea of the passage?(A). When making decisions in certain predictable situations, juries may commit inferential errors that obscure rather than reveal the truth.
(B). The views of human cognition held by psychologists on the one hand and by the legal profession are demonstrably dissimilar.
(C). When confronting powerful preconceptions, particularly shocking evidence, or complex situations, jurors make errors in judgment.
(D). The problem of inferential error by juries is typical of the difficulties with cognitive processes that people face in their everyday lives.
(E). Juries would probably make more reliable decisions if cognitive psychologists, rather than judges, instructed them about the problems inherent in drawing unwarranted conclusions.
2. Of the following hypothetical reforms in trial procedure, which one would the author be most likely to support as the best way to address the problem of jury inferential error?(A) a move away from jury trials
(B) the institution of minimum formal educational requirements for jurors
(C) the development of strict guidelines for defense testimony
(D) specific training for judges in the area of jury instruction
(E) restrictions on lawyers’ use of psychological research
3. In the second paragraph, the author’s primary purpose is to(A) refute the idea that the fact-finding process is a complicated exercise
(B) emphasize how carefully evidence must be presented in order to avoid jury inferential error
(C) explain how commonly held beliefs affect the Jury’s ability to ascertain the truth
(D) provide examples of situations that may precipitate jury errors
(E) recommend a method for minimizing mistakes by juries
4. Which one of the following best describes the author’s attitude toward the majority of judges today?(A) apprehensive about whether they are consistent in their instruction of juries
(B) doubtful of their ability to draw consistently correct conclusions based on the evidence
(C) critical of their failure to take into account potentially helpful research
(D) pessimistic about their willingness to make significant changes in trial procedure
(E) concerned about their allowing the presentation of complex and voluminous evidence in the courtroom
5. Which one of the following statements, if true, would most seriously undermine the author’s suggestion about the use of current psychological research in the courtroom?(A) All guidelines about human behavior must take account of variations in the patterns of human decision-making.
(B) Current models of how humans make decisions apply reliably to individuals but do not hold for decisions made by groups.
(C) The current conception of jury inferential error employed by judges has been in use for nearly a century.
(D) Inferential errors can be more easily predicted in controlled situations such as the trial of lawsuits than in other kinds of decision making processes.
(E) In certain predictable circumstances, juries are less susceptible to inferential errors than they are in other circumstances.
6. It can be inferred from the passage that the author would be most likely to agree with which of the following generalizations about lawyers?(A) They have a less sophisticated understanding of human cognition than do psychologists.
(B) They often present complex or voluminous information merely in order to confuse a jury.
(C) They are no better at making logical inferences from the testimony at a trial than are most judges.
(D) They have worked to help judges minimize jury inferential error.
(E) They are unrealistic about the ability of jurors to ascertain the truth.
7. The author would be most likely to agree with which one of the following generalizations about a jury’s decision making process?(A) The more evidence a jury has, the more likely it is that the jury will reach a reliable verdict.
(B) Juries usually overestimate the value of visual evidence such as photographs.
(C) Jurors have preconceptions about the behavior of defendants that prevent them from making an objective analysis of the evidence in a criminal trial.
(D) Most of the jurors who make inferential errors during a trial do so because they are unaccustomed to having to make difficult decisions based on inferences.
(E) The manner in which evidence is presented to a jury may influence the jury either to overestimate or to underestimate the value of that evidence.
