When I try to have somebody explain why they auto-play left, it too often sounds like the fallacy called circular reasoning.

Note: a fallacy is an invalid reasoning or argument.

Circular reasoning is a logical fallacy summed up as:

- A therefore B
- B therefore C
- C therefore …
- …
- … theferore A

However, none of A, B, C, etc. have sufficient premises to be logically valid.

As usual, I am open to hearing and being convinced by a solid demonstration.

When is it "not always true, though"?
