Because by the time you get the opportunity to verify the accuracy of the "recall", it's too late to challenge the mentalist about it. That's how those tricks (when they're tricks) work.
Imagine it like this: say you're at some mentalist's show, and she picks you out of the crowd. She asks you your birthdate, you tell her, she concentrates (silence in the audience) then suddendly she starts riffing off headlines from that day's newspapers. Why, she can even remember the crossword hints from the Times of Pallookaville! And even their answers! (well just one of them but-) Music! Lights! The audience clap their hands! The mentalist moves on to the next target.
Did you, at any point during all that, have any chance to challenge the accuracy of the mentalist's recall? Not really. Would you do it even if you could? Most people will dread so much being the asshat that ruins the show everyone paid to watch, that they'd never say anything, even if they had a tattoo of that damned crossword on their butt, solved and done.
And does it make any difference if you go back to your house and google the information and it's all made up? What 'you gonna do? Call up each one of those 1200 people who watched the show and tell them the mentalist is a fraud? 'Course it's a fraud. It's entertainment!
That's one setting and it's a bit formal, like, but ceteris paribus, the same goes for any situation where someone is pulling that sort of trick on you- the whole trick is to move fast and not give the mark time to think and react.
