I got this in BR but damn, I have to understand the question stem properly before going hunting for the answer. I eliminated the correct answer on first read but after slowing down my thoughts in BR I saw how C was right.
This was an interesting one because, despite being a Sufficient Assumption question, it is an example of where you need to make a “reasonable” additional assumption in order for the conclusion to be properly drawn. The question is which assumption LSAT writers think is small enough to be an entailment. I picked the correct answer here, but I don't think it's nearly as cut and dry as this explanation suggests. I'd note Ping's explanation suggests the text is referring to your journals from high school. That isn't textually supported. It's subject's recollections. "SUBJECTS REPORTS ABOUT THEIR PAST" is different from "SUBJECTS PAST (CONTEMPORANEOUS) REPORTS OF THEIR PAST." Memories are inherently unreliable. That is a plain fact about the world. The answer choice suggests that is not a leap we can make without being spelled out in an answer choice. Now, to the leap we are required to make... all measurements contain error, and once you get enough error, that limits conclusions. The point where the error is big enough to prevent conclusions about causality can vary dramatically depending on the details. Here, we’re told self report is highly susceptible to error. Is highly susceptible about the frequency of the error? Or about the magnitude? We don’t know. If it said "highly susceptible to really large errors" that might help, but it doesn't say that. We certainly don’t know the relative magnitude of the error compared to the causal relationship we’re examining. LSAT writers here expect you to assume that "highly susceptible to inaccuracy" entails "inaccurate enough that it can't reliably determine causality". This is an assumption many people make, but it is not accurate, and certainly not entailed. It’s an example of confusing relative for absolute. LSAT writers here are assuming that error is binary. Something is either accurate or inaccurate, and therefore being highly susceptible to inaccuracy is sufficient to make it meaningless. But error is NOT absolute, it is very specifically something that is always present, quantifiable, and relative. Error prevents conclusions precisely when it is large enough relative to the size of the effect we are trying to identify. We don’t know that is the case here. Now, I expect LSAT writers to be a few decades behind the domain experts on this sort of thing, so I would expect them to conclude that self report prevents causal inference (rather than self report complicates causal inference), but I was honestly surprised that it was in a “sufficient assumption” question. The question survives by process of elimination, but the correct answer choice does not allow the conclusion to be properly drawn.
I eliminated C because I thought "just because something is susceptable to inacuracy, does not gurentee we can't determine present characteristics." That's why I was looking for a "If, then" rule that gurenteed the conclusion about present characteristics
I eliminated (C) during the actual take and BR because I thought "highly susceptible to inaccuracy" didn't meet the burden of proof needed to 100% justify the conclusion. Now that I'm taking a third look at all the choices w/o timed pressure, I can see how this is obviously the right choice.
I'm fighting the urge to debate the logical validity of [highly susceptible to inaccuracy] = [100% inaccurate]. Instead, I'll just chalk it up to LSAT writers being tricky, and that (C) is absolutely right in relation to the other answer choices.
@SavannahMiller Read "cannot reliably determine" as "is not always accurate" which reads as "is sometimes inaccurate". And read "highly susceptible to inaccuracy" as "usually inaccurate".
"usually inaccurate" meets the burden of "is sometimes inaccurate".
The writers used quantitative sets without using always/usually/sometimes/many/some/etc. You have to read in those qualifiers.
What does "cannot reliably determine" mean? Well it means that at least some of the time, we cannot be accurate. And so on.
@coolcatsandtheirfunkystats If it is just a restatement of a Premise alone, then yes.
But if the premise is: Because i go on walks
and the Con is: I clear my head
it is quite possible that an AC for a SA question could be:
going on walks clears a person's head (this is a restatement of the premise and connects why going on walks supports the conclusion of clearing my head)
I was stuck between C and D, I thought D could have proven the conclusion as it stating the opposite of what the Premises are saying. So therefore it would prove, I don’t know that was my thought process.
For those that chose AC (A), keep in mind that with SA questions, we are trying to make the conclusion logically valid. In order to do so, we will more than likely choose the AC that uses the strongest language because it will do the best job at proving the conclusion to be 100% true. "may" is too weak of a claim, and won't help bridge that gap to the conclusion with 100% certainty. With sufficient assumptions we need 100% certainty that the conclusion will be true. Weak ACs (probably, could, may, not necessarily) are almost always wrong because they don't guarantee the conclusion.
This has helped me consistently chose the correct answer so far!
This class of questions is so frustrating for me. I feel like with each question type I have been able to eventually understand the ask and apply it but not here. I understand the ask but for some reason I just can never pick the right answer.
@lauetal I did alot of argument part classes and felt like that helped me with these since those questions force us to key in on premises and conclusions. Which seem to be key to these questions.
For this question I did something that worked for me at least. Im not sure if this method would work in other questions but it worked here!
Because retrospective studies of human subjects must use the subjects' reports about their own pasts, however ______, such studies cannot reliably determine the causes of human subjects' present characteristics.
That however is between the subjects reports and the conclusion about studies. So I took each AC and stuck it in that blank looking for answers about the subjects past. That narrowed it down for me to A and C. A said "may depend" which seemed like they didnt use them. Then C said "highly susceptible to inaccuracy." without any qualifier like the study "may" use them for example. So I went with C.
ive been consistently getting these right but only with mapping out the question after a really long time. Every question ive done on this module has been a minute or 2 over the target when it does not feel like I could have understood it faster.
At the same time on PT's its like sufficient assumption questions are frequently ones that I have trouble with even without this framework, so it just feels like this kind of question in general is harder than the rest. I pretty much always end up going over time because of them.
I had C, then changed to D. I felt that the wording on D matched a little bit better since it used "reliably," but didn't account for the "can reliably," where the stimulus was talking about "CANNOT reliably predict."

i dont want to mislead, but these types of questions just feel like summing up the argument. Thats my approach and its been working fairly well
This felt like a strengthen question also.
I got this in BR but damn, I have to understand the question stem properly before going hunting for the answer. I eliminated the correct answer on first read but after slowing down my thoughts in BR I saw how C was right.
got it right but i was 5 minutes over
it took me some time but I got it Thank God
I've started saying "ohhhh..kay" to wrong answers in JYs voice in my own head
For SA questions, am I right to generally throw out answer choices that use language like "may/in part/might/etc." like A does?

I eliminated C at first and got confused with B. Then I chose C in BR :')
I eliminated C because I thought "just because something is susceptable to inacuracy, does not gurentee we can't determine present characteristics." That's why I was looking for a "If, then" rule that gurenteed the conclusion about present characteristics
Goddamn

Was doing so well in this section but this question completely threw me off :(
So if an answer choice simply repeats a premise, it's automatically incorrect because it's not affecting the argument at all, right?
@coolcatsandtheirfunkystats That's the same conclusion I've come to
@coolcatsandtheirfunkystats If it is just a restatement of a Premise alone, then yes.
But if the premise is: Because i go on walks
and the Con is: I clear my head
it is quite possible that an AC for a SA question could be:

I was stuck between C and D, I thought D could have proven the conclusion as it stating the opposite of what the Premises are saying. So therefore it would prove, I don’t know that was my thought process.
Finally, my first time getting the correct answer on SA mm
My 2 cents literally nobody asked for:
For those that chose AC (A), keep in mind that with SA questions, we are trying to make the conclusion logically valid. In order to do so, we will more than likely choose the AC that uses the strongest language because it will do the best job at proving the conclusion to be 100% true.

Weak ACs (probably, could, may, not necessarily) are almost always wrong because they don't guarantee the conclusion.
This has helped me consistently chose the correct answer so far!
@HayleeHarris Thank you! This is super helpful.
ugh, finally got one right - I hate these!!
Wordy ahh question
idk why I don't just
read the answers before I answer
im losing my mind

Only 3 stars.........This one was a tough one to understand.
