If Pinocchio said the statement "My nose will grow now" it would cause a paradox.

Pinocchio's Paradox

So there’s a good chance you’ve not heard of this before, but if Pinocchio said the statement “My nose will grow now” it would cause be a paradox…

Let me explain…

Let me explain...

As we all know, Pinocchio’s nose grows when he tells a lie.

So if he said “my nose will grow now” – if his nose does grow that would mean he wasn’t lying, but if he wasn’t lying, his nose wouldn’t grow.

But then his statement would be a lie… so his nose would grow.. but then the statement wouldn’t be a lie… so his nose wouldn’t grow… but yeah, you get the idea..

Basically, his nose would have to grow to make Pinocchio’s statement not a lie, but then it can’t grow otherwise the statement would not be a lie.

Pinocchio’s Paradox origins.

Pinocchio's Paradox origins.

The Pinocchio paradox was thought of in February 2001 by an 11-year-old called Veronique Eldridge-Smith – the daughter of Peter Eldridge-Smith, who specializes in the philosophy of logic.

The article was first published in the journal Analysis, and the Pinocchio paradox rapidly became popular on the Internet.

“My nose will grow now” is the only paradox Pinocchio can cause by saying something.

For example, if he was to say, “I will sneeze now”, and he didn’t that would be a lie and his nose would grow.

Hope this makes sense & if you’ve got any more crazy paradox’s, let us know!

    Pinocchio says his nose will grow now
    So his nose doesn’t grow because he can’t grow it when he isn’t lying
    But he is lying so his nose will grow
    So he is telling the truth
    So his nose doesn’t grow because he is telling the truth.

    Basically the growth relies on lies so in the end his nose won’t grow no matter what if he is telling the truth.

    If Pinnochio looks his cricket friend in the eye and says “EVERY (emphasis) time I look at you my nose grows” what would happen then?

    I think that the secret option number C answer to this riddle or paradox is that Pinocchio will spontaneously combust and be erased from everybody’s memories and thus will never have existed to begin with

    Not to spoil the fun, but this isn’t really a paradox. A prediction of the future cannot be a lie. A prediction of the future can be wrong, but it is not a lie, unless one has seen the future, and knows the statement to be false, it cannot be a lie. Therefore, if Pinocchio’s nose grows, he has made a successful prediction. If it does not grow, he has made an unsuccessful situation, and his nose will not grow. However, if Pinocchio hadn’t seen the future but said that he had, this would be a lie, and his nose would grow.

    The real question is would his nose ever grow? If it is implied that he is lying, so that his nose will grow, then he would ultimately be telling the truth and his nose would never grow. On the other hand, if it didn’t grow then he would be lying and his nose would have to grow for telling a lie.

    The statement first is a lie, then it becomes true the instant after he says now… because then only then do you see that his nose grew after the lie

    If pinoccio lie his nose will grow and there is no chance his teling the truth even if his nose grow because deap down still lying, in the other way he can’t say the truth because he doesn’t know if his nose will grow so he’s hopping for his nose to grow

    He could also say “I’m lieing” to cause a paradox. As if his statement is true then his nose should grow, however it wouldnt grow, as if it grew he would be telling the truth, but if it didnt grow then it would grow as his statment ‘i’m lieying’ would then be a lie. Etc. etc

      Yeah, it’s a “this sentence is false” kind of thing. It’s a logical Paradox, if it Is false, then the statement is true, but if it’s true then it’s false. It cannot have values of both 1 and 0 at the same time.

        Unless its pinochio in quantum
