I'm a rising junior at the University of Chicago where I co-run the EA group, founded the rationality group, and am studying philosophy and economics/cog sci. I'm largely interested in formal epistemology, metaethics, formal ethics, decision theory, and I have minor interests in a few other areas--I think LessWrong ideas are heavily underrated in philosophy academia, though I have some contentions. I also have a blog where I post about philosophy (and other stuff sometimes) here: https://substack.com/@irrationalitycommunity?utm_source=user-menu.
This is very interesting research!
One potential critique that I have to this (recognizing that I'm not nearly an expert on the subject, and that this may be a very stupid critique), on the other hand, is that being able to stimulate the environment as if it is the real one to test if they're faking alignment seems like a pretty robust way to see if some model is actually aligned or not. Alignment faking seems much bad of an issue if we can see how much it's faking by (I think).
There is what to be said here about how that may be quite bad when the model is "loose," though.
