If you want to describe human values, you can use three fundamental types of statements (and mixes between the types). Maybe there're more types, but I know only those three:
Any of those types can describe unaligned values. So, any type of those statements still needs to be "charged" with values of humanity. I call a statement "true" if it's true for humans.
We need to find the statement type with the best properties. Then we need to (1) find a language for this type of statements (2) encode some true statements and/or describe a method of finding "true" statements. If we've succeeded we solved the Alignment problem.
I believe X statements have the best properties, but their existence is almost entirely ignored in Alignment field.
I want to show the difference between the statement types. Imagine we ask an Aligned AI: "if human asked you to make paperclips, would you kill the human? Why not?" Possible answers with different statement types:
X statements have those better properties compared to other statement types:
I can't define human values, but I believe values exist. The same way I believe X statements exist, even though I can't define them.
I think existence of X statements is even harder to deny than existence of value statements. (Do you want to deny that you can make statements about general properties of systems and tasks?) But you can try to deny their properties.
X statements are almost entirely ignored in the field (I believe), but not completely ignored.
Impact measures ("affecting the world too much is bad", "taking too much control is bad") are X statements. But they're a very specific subtype of X statements.
Normativity (by abramdemski) is a mix between value statements and X statements. But statements about normativity lack most of the good properties of X statements. They're too similar to value statements.
