There are two kinds of people.
You tell with the "monster in the hole in the ground" situation.
If you tell someone, pointing to a big hole in the ground that there is a giant monster down there, you cannot see what it looks like unless you stick your head in the hole. If you stick your head in the hole to look, there is a 50% chance it will bite off your head.
One type of person is going to think: "**** that! I am not going anywhere near that hole!"
The other type of person will not be able to resist. They just cannot help themselves. If they try to resist they will not sleep well, they will not take interest in other things, and all they can think about is figuring out what that monster looks like.
