Most jurors will be more inclined to reach a verdict favorable to one side if that side's case is based primarily on eyewitness testimony rather than on physical evidence backed by expert scientific testimony. Surprisingly, studies involving jurors in mock trials have found that this tendency survives even for those jurors who understand that eyewitness testimony is generally less reliable than is physical evidence backed by expert testimony.

Which of the following, if true, would most help to explain the surprising phenomenon described above?



(A) Jurors in mock trials usually spend less time deliberating and worrying about reaching the right verdict than do jurors in actual trials.

(B) Because expert testimony regarding physical evidence presented at trial is almost invariably given by witnesses testifying for one side or the other, many jurors regard such witnesses as biased.

(C) The credibility that a particular juror will assign to a particular eyewitness will be profoundly influenced by personal characteristics of the eyewitness including age.

(D) Even jurors who understand that eyewitnesses tend to be less reliable than physical evidence incorrectly believe they are better than the average juror at telling when an eyewitness’s testimony is reliable.

(E) The more complex the physical evidence presented at trial is, the less it will influence the jurors in reaching their verdict.

(A) This choice suggests a difference in the deliberation process between mock trials and actual trials but doesn't directly address the inclination to favor eyewitness testimony.

(B) This choice introduces bias in expert witnesses, but it doesn't directly explain why jurors would still prefer eyewitness testimony even when aware of its reliability issues.

(C) This choice introduces personal characteristics of the eyewitness, but it doesn't directly explain the tendency of jurors to favor eyewitness testimony despite knowing its general unreliability.

(D) This choice provides a possible explanation. If jurors believe they are better than average at discerning reliable eyewitness testimony, it could explain why they still favor it despite their understanding of its general unreliability.

(E) This choice suggests that the complexity of physical evidence reduces its influence on jurors, but it doesn't explain why jurors, even when aware of the reliability issues of eyewitness testimony, would still prefer it.

I am very confused about Choose D: jurors believe they are better than the average juror at telling when an eyewitness’s testimony is reliable -> this doesn’t mean that they are more inclined to reach a verdict favorable to this side that has eyewitness’s testimony. It can be the opposite.

­Exactly, (D) can go either way.

Please help with the explanation.
­This question is flawed because both (B) and (D) are argualby correct and (B) is probably better than (D).

So, it's probably best to just ignore this question.
­
This question just appeared on one of my official mocks, so ignoring is probably not an option. However, agree 100% that this looks flawed.

­Interesting. Maybe I was too cavalier after seeing that its source is marked "Other," but it definitely doesn't seem well constructed.

Which official mock did you see it in?­­­

I think the reason why B is wrong is that the answer is not focusing on the mock trial while the question seeks explanation for the Suprising phenomenon

@GMATNinja Could you please help here?

I believe both B and D provide enough justification for the phenomenon here. Option B states that jurors regard witnesses presenting physical evidence as biased - which in turn provides support as to why eyewitnesses are preferred.

Further, Option B mentions "trials" which can be both Mock as well as Actual trials. I'm not 100% convinced of the reasons for choosing B over D!

Thank you!

Please help with this question. I couldn't decide between B & D.
Only thing i had against (B) is ''many jurors''.
Who are those ''many jurors''? Are they who understand that eyewitness testimony is generally less reliable physical evidence OR the other ones?

MartyMurray Bunuel ashutosh_73 I ended up choosing D because the of the use of the word "generally" when talking about mock trials.
If jurors believe an eyewitness testimony is generally less reliable, they believe in other cases that it is as reliable or more reliable than physical evidence.

Given option D, we have the best explanation to why that is, these jurors believe they are probably better at at discerning reliable eyewitness testimony.

Option B was my second best choice but I ended up not going with it because it does not provide any explanation why in some cases jurors believe an eyewitness testimony is as reliable or more reliable.

True, i went with choice B as part of my gmat focus mock, but for some weird reason that was wrong. The answer needs to be consistent- and I feel out of the two B) is more consistent than D)

­I got this question also wrong and chose B. However, I am noticing a specific pattern in other questions. When we compare 2 entities in the prompt, this comparison is needed in the answer choices. Could it be the cases that because choice D also uses a comparison between eye witnesses and physical evidence, whereas B simply makes a statement why eye witnesses are not reliable, choice B cannot be correct as it fails to compare? Even if eye witnesses are considered by those jurors as biased, we don't know if those same jurors actually believe more in eye witnesses than in physical evidence. It's just an absolute statement without providing any context if one is preferred over the other.­

I eliminated B because it says jurors think witnesses are biased and this deepens the paradox. Why are the jurors taking their side even though they regard them as biased? Also since it is the witness presenting the physical evidence the question still remains whether the jurors view is due to the evidence or the witness testimony. Does that make sense??­
