You can only make a decision based on what you know, see, or so.
It is not different with computers.
When something is unknown to you but would have changed your decision if you
knew, then going from the situation that you don't know  to the state that you
do know is called horizon effect.

Or sometimes people call the horizon effect just the former situation, that a
wrong decission is made because the engine is uninformed, or at least
under-informed.
