Yes. But how would you know?

If somebody said that to me i would at that point not care enough to think about it.

Do they believe it?

If they're telling the truth then they're not a liar, even though they claim to be.

It's a thought experiment. There's no hidden information.

Ya I get that. It was just a response to your original question

no they wouldn't and they wouldn't be telling the truth even if they are known compulsive liars saying they are compulsive liars.

what are you, a human lie detector?

I'd say just because you don't lie once, when you say you lie alot, it does not not make you a liar. The reverse also applies, so I would judge out from whether you lie about the things that actually matter.

and how do I know they're lying?

My brain hurts

Frege, Russell and Gödel wpould enjoy this I'm sure.

I would assume that this wasn't a logical fallacy question, and that like a normal human being I have to interpret the fact if he is lying about being a liar, which since he told me, and I don't live in a word puzzle, I would just assume he decided to tell me so I would be aware of his proclivity for fancy.

i remember in air rivals when i asked the nation leader to add my name in the scammer list for the weekly mail warnings of scammers. he didn't want to because i'm not scammer.. :'( but in the end i kept sending him trade requests while he made duels, he got angry and finally called me a scammer! (^_^) and then ppl would send me private messages asking if i'm scammer.. hahaha...

The ends do not justify the means. If their intention was to deceive, then they are a liar.

Besides, a liar doesn't get to pretend to be trustworthy because they occasionally say things that are factually correct. If you consider their pattern of behaviour, the truth becomes more clear.

Ahhh the good old Crete paradox.

Well, define "liar". If it only means "I often lie", this checks out.
