The Idea of this SCP is an object (I am thinking either an oak ball that speaks or a computer of some sort) that can incorrectly predict the future. While the SCP's predictions are false, they all are falsely accurate. For example, if a person asks it, "Will the president win the election again?", and it answers yes, it means that the president will not win the election. How this happens, for example a low vote count or death, is not explained, though all of the reverse predictions will be true.
I still have to work on some things, like its class and how it could be contained, though is there anything wrong with this, or that I need to change?
