I think you’re misinterpreting Yudkowsky. He’s not saying that all ethics is pragmatic. He’s saying that pragmatics is ethics. Previously in the paragraph, he listed other, non-pragmatic ethical reasons to seek truth.
As for the orders of magnitude, it’s log(.9) - log(.02234) = 1.6 orders of magnitude. That’s closer to 2 than to 1.
