I might then write down p(Eliezer Yupkowski is the guru of Less Wrong)=0.999999999. Once again, I would be mistaken. It is "Yudkowski", not "Yupkowski") But in neither case am I in unrecoverable epistemic trouble. Those were typos. Correcting them is a simple search-and-replace, not a Bayesian updating. Or so I understand.

It's Yudkowsky. Might want to update your general confidence evaluations.
