I don’t think EAs have a comparative advantage in policy/research in general, but I do think some EAs have a comparative advantage in doing some specific kinds of policy/research for other EAs, since EAs care more than many (not all) clients about certain analytic features, e.g. scope-sensitivity, focus on counterfactual impact, probability calibration, reasoning transparency of a particular sort, a tolerance for certain kinds of weirdness, etc.
