Write a sentence whose truthfulness cannot be determined before you try to find it out, but is immediately decided as soon as you begin to find it. The truthfulness must be objective and not subjective. In the case where the sentence can be interpreted in more than one way (ambiguity), you should add context or explanation so the sentence has an unambiguous meaning.

To clarify by examples:

• "This sentence is false" is a sentence whose truthfulness can never be determined.


• "I am asleep" is a sentence whose truthfulness is always decided, even though you may not be able to find it out.


• "PHP is the best language in the world" is always subjective, despite being immediately decidable.


• "I hit a man with a bat" is an ambiguous sentence.

None of the examples listed above is valid answer. However, the last sentence may be disambiguate with additional information, such as "the bat belongs to me".

How about:

This answer is going to be the accepted one.

:)

To add onto the existing example sentence:

I am trying to find out the truth value of this sentence, or this sentence is false.

Because:

If you try to work it out, it is true, otherwise, it can neither be true nor false.

What about:

A user has read this sentence.

Because:

You don't know if anyone has, but as soon as you read it you already knowfor sure it's true

To also add to the existing, if you count this:

The number of letters in this sentence is forty-two.

There's a bar near here that has the following permanently etched into the wall:

"Free beer Tomorrow."

One cannot (absolutely) determine the validity of the statement without attempting its promise, whereupon, to his dismay, he finds out that there is definitely going to be

"Free beer Tomorrow."

My try:

Read this sentence until it's end, fait accompli!

My solution

This puzzle has no solution

A sentence requires a few basic things.
If the above statment qualifies as a valid sentence then so is this:

"Meow," said Schrödinger's cat.

And this:

Schrödinger's cat did not make sound.

It follows that:

The state in which the cat of Schrödinger existed was unverifiably predictable and although it is not known if the philosopher was a yogi or not, his attempts at non-binary knowledge through abstract thought, is certainly one for the catalogues of momentous thought.
