When new laws imposing strict penalties for misleading corporate discl

The argument tells us that the amount and accuracy of info released has increased. So one would expect the accuracy of predictions based on info released to increase.
But we are told that the accuracy of predictions has not increased. So there is some force that is acting in the opposite direction. Option (E) says that the increased amount of info has made it difficult to manage all the info available. So with the new laws, though amount and accuracy of info has increased, manageability has decreased. That is the reason the accuracy of predictions based on this info has remained the same.

As for (D), all it says is that many sources are used for info. But if one source becomes more accurate, we would expect at least a little bit increase in the accuracy of predictions. We are not given that the accuracy of other sources reduces to keep the accuracy of predictions the same. Hence (D) is not correct.

Hi Experts GMATNinja KarishmaB Bunuel fiftyoneverbal

I completely agree with the reason of (E) being the correct answer in comparison to (D) which is shaky in its reasoning. But is it not irrelevant with the question argument? What if there are more sophisticated methods available with the analysts to review the piece meal information? After all there should be some improvements in the analysts models when some info is inducted into that model...I think so...

I mean it puts more importance to the difficulty of processing that information.

I am not arguing with the answer provided in the official Q but want to know where did I go wrong in my thinking??

Thanks!

I picked C because if the information about corporations was true even before the laws were passed, then it's likely that the predictions of the analysts have been inaccurate all along. This would also explain why the accuracy did not improve after the new laws.



E is much harder to justify because if increased info is making organization of info difficult, then the inaccuracy should have increased. But perhaps this is where the trap lies: given the conclusion does say that inaccurate info has not decreased, it could mean that it has either stayed the same or increased.

Nonetheless, if presented with a similar question, I'm not sure I'd be able to justify picking a choice such as E over C.

C) Even before the new laws were passed, the information most corporations released was true.

(C) is problematic because we are given in the argument that "amount and accuracy of information disclosed" would increase under new law.
So even if whatever the corps were releasing was true, perhaps they were hiding important information.
For example, if they were telling the truth about their assets but hiding their liabilities, it would still lead to misleading analysis. We now expect to get more and more accurate information so we would expect our analysis to get better.

E) The more pieces of information corporations release, the more difficult it becomes for anyone to organize them in a manageable way.

(E) makes sense because along with the advantage of the new law, it introduces a problem associated with it. That could neutralise the advantage and hence could be responsible for similar number of errors in the analysis as before.
The new law is bringing in advantages as per the argument and there is no debate about that. What we have to show is why our analysis may still be the same, accuracy wise.

The question asks us to find the answer choice that "best" explains the discrepancy in the passage, not the one that perfectly resolves the discrepancy. So we're just looking for the option that provides a better explanation than the other options, even if that answer choice isn't 100% airtight.

(E) tells us that "the more pieces of information corporations release, the more difficult it becomes for anyone to organize them in a manageable way." We know from the passage that the new laws have provided an "increased amount[...] of information."

Putting these two things together, we know that the analysts have a more difficult job managing information under the new law. This new difficulty could, to some extent, counterbalance the helpful things about the new law. So, (E) provides an explanation for the discrepancy in the passage.

Could there be improved models, as you've said? Potentially, but we really don't have any information to support that inference. More to the point, even if there are outlier cases in which (E) isn't a perfect explanation, it still does a better job than any of the other answer choices.

(E) is the correct answer.

I hope that helps!

Though GMATNinja has already explained it brilliantly, I would like add one last point here:

Look at the question stem: Which of the following would, if true, best explain the discrepancy outlined above?

So we need to assume that the data given in the option is true.

E) The more pieces of information corporations release, the more difficult it becomes for anyone to organize them in a manageable way.

The more the information, the more difficult it is to organize in a manageable way. Perhaps which piece will be useful where in the model becomes difficult, perhaps analysts make errors in collating the pieces for the model - we don't know. The point is, it brings in new difficulties and that's what we are told.

Hence, it doesn't matter what our logic tells us from our real world experience, the point is that if it were true that more info is hard to organize properly, then would it explain why accuracy has not improved?

Can you please state more statements that if true can help explain this given discrepancy ?

Usually, you can explain a given discrepancy in various ways. That is why pre-thinking is not very useful in such questions.
Here, if we say that the most important pieces of info on which the accuracy of predictions depend are still not available under these laws, then also we can explain the paradox.

Was stuck between A and E.
The error I made- I thought that even when the information and accuracy is increasing, companies might be finding a way out as to what does not construe as 'misleading' and find a way out to only provide the information which does not reflect flaws in their corporate performance. Basically they will find a loophole in the law. I made an additional assumption which is actually a big no-no.
E thus seemed weaker.

Experienced this for the first time, I brought in the biases/ outside information based on my background and observed realities ( I am a chartered accountant thus aware of the possibility of companies wiggling out of the scope of law).

Learnings-
1. DO NOT bring in additional assumptions
2. Beware of your biases in questions you can relate to

Hi Karishma,
option E: can you tell me how we go from "difficult to organize" to "wrong predictions"? This requires an assumption that any data that's difficult to organize leads to less accurate predictions. Why are we assuming that? (From real-life experience, I will say difficult to organize data makes it harder to analyze but doesn't neceesarily lead to inaccurate predictions, esp if the data is of superior quality)

Following this discussion, I believe the real issue is between D and E now. Argument is, if we have to make assumptions to get the question correct, we can do it for either D or E. So why is only E right? I think i can help.
Let us see the assumptions we have to make to get each of these options right:


To make this option right anwer, we have to assume that one of the (or many) other sources must have reduced in their accuracy. And this can explain the descripancy.


To make this option the right option, we have to assume that the increase in difficulty to organize WILL translate into not being able to BETTER organize (Read question again, it says: number of inaccurate analysts' predictions has not in fact decreased (this means, the accuracy either has remained same or has gooten worse).

Now, both seem reasonable. In such a scenario, we have to see which assumption of ours is less biased and hence more likely.

For the assumption in option D, we are assuming that one of the (or many) other sources must have reduced in their accuracy. But is there any support in the options that helps us to go this route? Nope! We just assumed it because we wanted to prove this option correct. One could similarly assume that the accuracy of these sources actually increased and hence claim the option to be incorrect. So, our position here is a bit weak and biased.

Now, for the assumption in option E, do we have any support? A weak support but yes it is there! It says "the more difficult it becomes for anyone to organize them". This essentially says things are becoming more difficult. Therefore, we defientely can not expect something good out of it. At best case, things will remain same, but at worst the accuracy will fall. It is in line with what we expect. So this support gives us a few brownie points here. Hence correct option is E.

Hope it helps.
