What circular reasoning is
An argument is circular when its premise and conclusion say essentially the same thing in different words. Instead of offering independent support, the argument assumes the very point it is supposed to prove. Logicians call this "begging the question."
Worked example
"This novel is the best of the year because no other novel published this year is as good."
"Best of the year" and "no other is as good" are the same claim restated. The premise provides no independent reason; it just rephrases the conclusion. That is the circle.
Compare a non-circular version: "This novel is the best of the year because it won three major literary prizes that no other novel won." Now the premise is a separate fact.
How to catch it
Read the premise and conclusion side by side and ask: does the premise give me a new reason, or does it just repeat the conclusion in new clothes? If you could swap the two sentences and the argument would read the same, it is circular.
Answer choices phrase it as "presupposes what it sets out to prove" or "the conclusion is among the premises." Verbloom's structure view shows when a premise and conclusion are really one claim wearing two outfits.
Frequently asked questions
Is "begging the question" the same as circular reasoning?
In LSAT terms, yes — both describe an argument that assumes its conclusion among its premises rather than supporting it independently.
How common is circular reasoning on the LSAT?
It is one of the rarer named flaws, but it appears, and it is easy points once you can recognize the premise-equals-conclusion pattern.
What's the fastest test for circularity?
Ask whether the premise would still be accepted by someone who doubts the conclusion. If accepting the premise already requires accepting the conclusion, the argument is circular.
