I don’t understand what you mean by “conditional on being implemented.” Do you mean that for each policy, it is implemented regardless of being impossible, then out of these words we find the number that have gotten better relative to their controls? Or do you mean that we find the number of possible worlds in which the policy is implemented, and compare it to a similar possible world in which it is not, and determine if a positive correlation between “has Policy X implemented” and “is a world with Y utilons”? The former doesn’t seem right, but in context the latter doesn’t seem to fit.
