What is out of score?

[ganbayou]

Hi,
So when I read explanations here I saw ppl say "out of scope" a lot.
Such as...since this is talking about "other" people, it's out of scope or unrelated...etc
But I think I saw some St/Weaken questions actually use those "other cases but in similar situation" to support or weaken the result of the incident or argument in the stimulus.
So my question is when is it allowable to use "other cases" for argument and when is not related...???
This confuses me a lot and actually whenever I see "out of scope"...this word, this frustrates me a lot...

This is the mark of someone who has been studying the LSAT for a while. That's great!

At some point, most of us struggle to find the line of what is acceptable new information to bring in, and what isn't. Here's how I look at it.

First, it's important to know when it's okay to bring in outside information. For example, it wouldn't make a lot of sense to bring in new information on an Inference question. But it does make a lot of sense on Strengthen, Weaken, and Explain questions. When you're playing a linking game on Sufficient or Necessary Assumptions it's a bad idea. But on Necessary Assumptions where you're defending the argument from some outside consideration that would be devastating to the argument, it's fine. Go through each question type and ask yourself, is new information called for?

Second, make sure the outside information doesn't rest on an assumption, but do accept connections from the real world that are common knowledge. Don't ask yourself whether this is true in the real world, ask yourself whether the average person would say this is true in the real world. If the answer is yes, accept it.

Hope that helps!
