when I am confronted with new information, I add that into my belief system and my belief system changes accordingly
You've misunderstood the paper
It's not about information. The argument is about disagreement among epistemic peers. We all have the same information. You've not provided any information I didn't already know. I've not provided any information you didn't already know. We've been exchanging theories, not information.
The paper is about the status of disagreement in conclusions based on the same information.
As I said in my other comment, if you really can't tell the difference between a theory and the facts on which it is based, then we can't possibly have a rational discussion since rational discussion is premised entirely on that distinction.
We don't discuss facts, we demonstrate them by the presentation of evidence. We discuss theories drawn from those facts.
