I suspect that your estimation of “how smart do these people seem” might be somewhat contingent on research taste. Most MATS research projects are in prosaic AI safety fields like oversight & control, evals, and non-”science of DL” interpretability, while most PIBBSS research has been in “biology/physics-inspired” interpretability, agent foundations, and (recently) novel policy approaches (all of which MATS has supported historically).
I think this is less a matter of my particular taste, and more a matter of selection pressures producing genuinely different skill levels between different research areas. People notoriously focus on oversight/control/evals/specific interp over foundations/generalizable interp because the former are easier. So when one talks to people in those different areas, there’s a very noticeable tendency for the foundations/generalizable interp people to be noticeably smarter, more experienced, and/or more competent. And in the other direction, stronger people tend to be more often drawn to the more challenging problems of foundations or generalizable interp.
So possibly a MATS apologist reply would be: yeah, the MATS portfolio is more loaded on the sort of work that’s accessible to relatively-mid researchers, so naturally MATS ends up with more relatively-mid researchers. Which is not necessarily a bad thing.
I don’t agree with the following claims (which might misrepresent you):
“Skill levels” are domain agnostic.
Frontier oversight, control, evals, and non-”science of DL” interp research is strictly easier in practice than frontier agent foundations and “science of DL” interp research.
The main reason there is more funding/interest in the former category than the latter is due to skill issues, rather than worldview differences and clarity of scope.
MATS has mid researchers relative to other programs.
