(This should_T terminology was discouraged by Eliezer in the sequences, perhaps since it invites incorrect moral-relativistic thinking, as if any decision problem can be assumed as own by any other, and also makes you think of ways of referring to morality, while seeing it as a black box, instead of looking inside morality. And you have to look inside even to refer to it, but won't notice that until you stop referring and try looking.)

I had no idea what Eliezer was talking about originally until I started thinking in terms of should_T. Based on that and the general level of confusion among people trying to understand his metaethics, I concluded that EY was wrong - more people would understand if he talked in terms of should_T. Based on some of the back and forth here, I'm revising that opinion somewhat. Apparently this stuff is just confusing and I may just be atypical in being able to initially understand it better in those terms.
