Question

You have a stack of 23 cards. Each card has an image of a cross on one side, and an image of a circle on the other side. You know that 14 cards in the stack are laying with the cross up, and therefore 9 cards are with the circle up. But you don't know in which order the cards are. Moreover, you are in a completely dark room, so you can't see anything.

How can you, without seeing anything, divide the stack of cards in two smaller stacks, in such a way that both stacks have the same number of cards with a cross up?

This is not a trick question designed to waste your time. This is a real logic puzzle.

Set aside 9 cards. Flip the other 14 over.

However many crosses are in the 9 stack will be equal to the count of circles in the 14 that when flipped over become crosses.

forgot to put in spoiler...

But if we set the 9 cards with circles aside,and flip the other 14 cards,we will have all with circles .
