Once management recognizes that there is something to measure, I think they do an OK job measuring it - secret shoppers come to mind. But there's something more subtle about when you take for granted that G = G* and don't even think to verbalize your true values, so can't measure them.

The secret shoppers are a variant of "the king going incognito"-- but not as good in some ways because they may be tasked with evaluating according to a checklist, and thus could still be trapped by G vs G*.

I believe that the problem isn't that true values aren't verbalized, it's that they can't be fully verbalized. Language is too low-bandwidth to capture all the aspects of a situation.

The point of a king going incognito isn't just to enforce existing, verbalized rules, it's to see how things are in the kingdom. It's a bit easier for a king than an AI because a king is more like a subject than an AI is like people.
