Most people in the field expect that the hardest part of the problem is “robustly align AI with any goal”. I expect AGIs to have a very sophisticated understanding of human values, along with many other concepts. The question is how we can precisely select which concepts they’ll be motivated by.
What I’m struggling with is how we’d plausibly get from (1) ‘align with any human goal’ to (2) ‘align with all relevant goals across all humans in such a way that we actually minimize global catastrophic risks’.
In my view, getting to (1) only gets us about 2% of the way towards (2), and doesn’t come anywhere close to ‘solving alignment’ in a way that would allow for safe AGI.
Also, I don’t see how AGIs could develop a provably, interpretably, ‘very sophisticated understanding of human values’ if alignment researchers don’t have a sophisticated understanding of human values that they could test against the AGI’s understanding.
At least, it seems like we’d need a strong ‘training set’ of human values that includes plausibly complete coverage of the ‘deployment set’ of human values the AGI would actually encounter in the real world—and I don’t see how we’d get a decent training set of values without quite a thorough understanding of the nature and diversity of human values.
I’m raising these issues not to be contrarian or ornery, just out of a genuine puzzlement about the long-term game plan in research on alignment with human values, and why alignment researchers seem often uninterested in behavioral sciences research on human values.

I don’t think anyone is aiming for provable alignment properties (except maybe for Stuart Russell); this just seems too hard.
But if AGIs could develop a very sophisticated understanding of other domains that humans don’t understand very well, by virtue of being more intelligent than humans, I don’t see why they wouldn’t be able to understand this domain very well too.

This is how classic ML would do it. But in the modern paradigm, ML systems can infer all sorts of information from being trained on a very wide range of data (e.g. all the books, all the internet, etc), and so we should expect that they can infer human values from that too. There’s some preliminary evidence that language models can perform well on common-sense moral reasoning, and alignment researchers generally expect that future language models will be capable of answering questions about ethics to a superhuman level “by default”.
More generally, it sounds like you’re gesturing towards the difference between “narrow alignment” and “ambitious alignment”, as discussed in this blog post. Broadly speaking, the goal of the former is basically to have AI that can be controlled; the goal of the latter is to have AI that could be trusted steer the world. One reason that most researchers focus on the former is because if we could narrowly align AI, we could then use it to help us with the more complex task of ambitious alignment. And the properties required for an AI to be narrowly aligned (like “helpful”, “honest”, etc) are sufficiently common-sense that I don’t think we gain much from a very in-depth study of them.
I feel like we shouldn’t expect to be able to express the Values Of Humanity to an AGI in order for it to be safe—in the same way that humans are currently mostly safe towards the rest of humanity despite not being able to articulate those Values Of Humanity themselves. There’s something stopping one person (even a very rich or powerful one) from killing everyone else, and it’s not explicit knowledge.

Richard—thanks for your reply.

Richard—thanks very much for your quick and helpful reply. I’ll have a look at the links you included, and ruminate about this further...
