I believe nothing as beliefs are incompatible with that learning. The mind is configured to protect beliefs, and the only counter is to root out the beliefs, be aware of them and be ready to sprinkle a little salt on them as needed.
What do you mean here? Of course you believe things about reality. Are you just saying you are open to changing your currently tentatively held beliefs?

I define "belief" as an emotionally accepted truth that needs no verification. "God exists" is a belief. "Fox News is fair and balanced" is a belief. According to noted skeptic Michael Shermer in The Believing Brain beliefs come first and are defended later. He further argues with strong scientific backing that information that tends to weaken or refute the belief is not even processed by the brain. "Fox News is BS" is not even heard by a believer in Fox News. The "La, la, la, I can't hear you" is not figurative according to Shermer, it is a true statement.
I don't confuse "belief" with "true" in regard to statements or "real" in regard to the material world. Both "true" and "real" are ultimately verifiable by independent means. "You are 33" is a statement that I tentatively accept as true, but if someone else said it is false, we could resolve the dispute factually with documentation. "The chair is real" can be verified by sitting on it. You need not believe the chair is real. If you were concerned you would sit tentatively and if it seemed substantial possibly rock on it to verify that it is functional as a chair.
