Simplistic version of this is just asking the question in 2 ways - ask for confirmation that the answer is no, then ask for confirmation that the answer is yes :)
A corollary for natural intelligence: if you can prove that all foos are bar, and that all foos are not bar, that's a good time to suspect that no foos actually exist.
(I still don't understand why everyone seems happy to conflate "intelligence" with fact-retrieval?)

If it's sure it won't confirm it both ways.

Because it's useful and impossible till very recently.
Because there is no single widely accepted definition of intelligence.
No widely accepted definition, but fact retrieval is outside of any of the ones with which I'm familiar.
That works for yes/no questions, but not for informational questions, like "Where's the Eiffel Tower?".
