Passage

Criminal courts frequently rely on accomplice witnesses (witnesses who testify regarding the role of an alleged co-conspirator in a crime) and jailhouse informants (witnesses who provide testimony based on information obtained while incarcerated) for prosecutorial information. Typically the testimony provided by such cooperating witnesses includes information which can include a purported confession to the crime.

Information from a cooperating witness is often provided in exchange for a reduced sentence or some other incentive. This kind of inducement creates a situation that is highly conducive to evidence fabrication on the part of the cooperating witness. In fact, one recent study concluded that lying to gain and little to lose by testifying falsely.

While courts have recognized the unreliable nature of evidence obtained through bartered testimony, they have held that safeguards are in place to adequately protect the accused against a conviction based on false testimony. These safeguards allow effective cross-examination of a cooperating witness and enable the jury to consider a witnessʼs motivations. However, the exchange between prosecution and witness does not have to be disclosed to the jury.

In addition, psychological research on confession testimony—confessions obtained by investigators directly from the accused—reveal further problems with bartered testimony. This research indicates that jurors give undue weight to confession evidence when rendering guilt decisions. This effect is especially notable in cases where jurors are aware that a defendant has been offered an fail to realize the effect that an incentive may have on a cooperating witnessʼs behavior.

A common psychological phenomenon may account for jurorsʼ superficial examination of confession evidence. Studies show that people tend to explain the behavior of others in terms of internal dispositions or attitudes as opposed to external, situational factors. In one study, regardless of whether confession evidence was obtained via negative pressure (threats of testimony as atonement rather than deducing that external factors made it expedient to give the testimony.

Answer choices

  1. Too Strong: never Too Specific: coercion2% picked this

    Evidence obtained through coercion, whether that coercion results from positive pressure or negative pressure, can never

    The author isn't saying that we can never regard this as reliable evidence. She's only stressing that jurors put more faith into it than they should. Also, calling bartered testimony "evidence obtained through coercion" is too specific. Some bartered testimony is obtained through coercion but the passage was not using those ideas interchangeably.

  2. Correct54% picked this

    Numerous considerations suggest that the courts? reliance on the testimony of accomplice witnesses and jailhouse informants may result in

    Why this is right

    This nicely captures "we have a legal problem: bartered testimony is prone to be flawed, since the people offering it are doing so for self-interested reasons, and the jurors hearing it put too much trust in its authenticity". The language about "convictions based on false testimony" didn't land well with me on a first read. It seems true on a common sense level, but I didn't remember hearing that emphasized in the passage. But when we research our qualms, we can see that this language is discussed at the beginning of the second paragraph. Courts hold that they adequately protect the accused against conviction based on false testimony, and naturally our author pivots with a "However, these safeguards do not always provide protection (against conviction based on false testimony".

    Skill tested: Main Point · how this choice captures the passage's function is the move to repeat next time.

  3. Too Narrow12% picked this

    Studies show that jurors give undue weight to confession testimony, a fact that may be explained by people?s general tendency to ignore situational factors

    This is pretty good, but it only captures the last two paragraphs. It leaves out the conversation involving the skewed incentives of the prisoners / accomplices who are providing the bartered testimony. It feels like only half of the Main Point, because the problem the author is putting together is "the providers of the testimony have reason to fib" + "the people hearing the testimony aren't good at being properly skeptical".

  4. Out of Scope: traditional legal arguments21% picked this

    Traditional legal arguments offered in support of permitting the testimony of accomplice witnesses and jailhouse informants are based on a set of assumptions

    This passage didn't pit new studies against traditional legal arguments. The closest thing we have to that is "While courts have recognized .... " at the beginning of the 2nd paragraph. But the passage doesn't enumerate a set of assumptions and then counter them with studies.

  5. Too Strong: substantial / heavily Too Narrow11% picked this

    There is substantial evidence to indicate that the testimony of accomplice witnesses and jailhouse informants is heavily influenced by

    While the author is certainly emphasizing the risk of inaccurate bartered testimony based on the incentives, we can't find lines in the passage that say "substantial evidence that testimony is heavily influenced". Furthermore, this answer would have the same downside that (C) had: it only captures half the problem. (E) focuses on the skewed incentives of the providers of bartered testimony. (C) focuses on the undue faith jurors put into bartered testimony. Our correct answer should feel like it's broad enough to cover both of those two central facets of the problem. Our correct answer says "numerous considerations", which leaves space for both of these things.
