I regret I don’t have much insight to offer on the general point. When I was looking into the bibliometrics myself, very broad comparison to (e.g.) Norwegian computer scientists gave figures like ‘~0.5 to 1 paper per person year’, which MIRI’s track record seemed about on par if we look at peer reviewed technical work. I wouldn’t be surprised to find better performing research groups (in terms of papers/​highly cited papers), but slightly moreso if these groups were doing AI safety work.
