A is a liar no matter what.  If A is speaking the truth by saying "I never speak the truth," then he is calling himself a liar.  If he is lying with that statement, and he does speak the truth then he lied about never speaking the truth.  Once again he is a liar.

As far as an actual statistic, I'm not sure.  However, I think that people lie in court all the time.  People are either honest or dishonest... I don't think that swearing to tell the truth will automaticaly want to make a dishonest person want to tell the truth... it just means that if they don't tell the truth when they swore to, then it's illegal.  And hey, if they are already on trial for something illegal, it's probably not going to bother them if they do something ELSE that's illegal.

When someone says, "I am lying"  They are usally talking about the event they just described to you.  For example\n\nI won the lottery.  I am lying.  I didn't.  He/she is lying about the lottery.  They however, are telling the truth about lying as they didn't realy win.  \n\nThough its hard to believe anyone once they lie because whats to say when they're "telling the truth" isn't some lie.

You cannot retract a false statement if you knew that it was false when you gave it. It can/will be used against you. \n\nIf you did not know it was false, and found out at a later time, tell them. They will thank you.

I would ask, "What would the other angel say about your pathway? to each of them. One would say, "He would say that my pathway leads to Hell," (which is the truth, otherwise if he were lying, then the other angel would be the truth teller, and lier would not say that that would be what the other would say, becuase that would be the telling the truth) and then the other would say, "He would say me pathway leads to heaven." (which is a lie, becuase if he were the truth teller, the other angel would be the lyer, and the lyer would not say that other's led to heaven, otherwise, he would be telling the truth)So, the angel that said, "He would say that my pathway lead to Hell," Is the path that leads to heaven.

the rabbit is telling the truth \nb/c\nif the cat were telling the truth then alice would also be telling the truth (opposite of alice is lying)\nand if alice were telling the truth then the cat's statement would be true that the rabbit is lying and the rabbit can't be lying and telling the truth. \n\nTherefore must be the rabbit who is telling the truth that alice is lying.

An out of sourt statement by other than the person on the stand (the declarant) to assert the truth of the matter put forward.\n\nI hope this is what you needed.

What you are saying is that A, B and C either always tell the truth, or always lie.\n\nLet's assume that A is telling the truth (in family T) when he says "either I belong or B belongs to a different family from the other two".\n\nWe already are assuming that A is in T (truthtellers). So that would mean that B is in the family of F (liars). We can't determine if C is in T or F because in either case, the statement could be true.\n\nOn the other hand, A could be lying (F family) and then his statement would have to be false. So that would mean that B is in the F family also. Again we can't tell what family C is in.\n\nSo the possible combinations are:\n\nABC: TFT\nABC: TFF\nABC: FFT\nABC: FFF\n\nThe best we can tell from this information then is that B must be in the F family (liars). You can't tell anything about A or C without additional statements.\n\nAnswer: B is in the family of liars (F)

Well you shouldn't be lying in the first place. It has been my experience that the truth alway's comes out. It is the nature of truth to come out and if you have to lie, be prepared when you least expect it, for the truth to come out.

An exaggeration is based on truth, lying isn't.

If you are telling the truth, then the statement, "Everything I tell you is a lie," is a lie itself.  If you are lying, then the statement would actually be true...which brings us back to you telling the truth.  It's all just one big circle that never, ever ends!

It is best to tell the truth.  Not telling the truth can lead to a cascade of lies as you try to cover up your tracks.  While there may be a punishment in the short term, in the long run, you will have a lot more trust and leeway than if someone found out that what you said before was a lie.  They will be left wondering about everything you said and you will be unable to convince them even if you are telling the truth.
