No, I don't "believe" the world will end on Saturday. I also don't "not believe" the world will end on Saturday. A stupid reader would say: "so you're on the fence", and observant reader would note: "so you choose to not even acknowledge it".
Here's a hypothetical conversation with an imaginary reader
Reader "But what if you're wrong"
Me "about what?"
Reader "Judgement day"
Me "Well, what if I am wrong about there not being a colony of smurfs on the sun?"
Reader "That's ridiculous"
