FLAW- circular reasoning

clarkermclarkerm Alum Member

I'd say I'm pretty darn familiar with the 19 common types of flaws. However, I feel like I've never seen a circular reasoning flaw actually on a PT. Sometimes I second guess myself on a tricky flaw question when it's in the AC's. Anyway, would love it if anyone has come across one of these flaws in their recent PT's?

I'm into the high 60's series, so hopefully I haven't been oblivious to them all this time. But I do think they are a rarer flaw.

    Hmmm... I could be wrong, but I could swear I came across one in a PT from the early 40s.

    I haven't done a lot of PTs, but I agree that it's rare although I think I have come across a few times while I was drilling Flaw questions.

    For example, it's an old PT, but I think PT6.S3.Q8 is an example of circular reasoning.

    Also, I've recently done a 5-star difficulty question on circular reasoning (PT49.S2.Q23):

    I've def come across a few, but I do agree that they are not that common. Usually when I see them, I have to double check to make sure what the flaw is since I'm not used to seeing them a lot. the same goes for the flaw of using a term twice or whatever lol.

    circular reasoning questions are way more prevalent in the old tests.

    Well for most of the LSAT's history Circular Reasoning was a throwaway flaw that was just never the correct answer choice. Then along came a PT in the 80's and'll see
