In the linked post, I discuss revealed preference analysis and argue that claims about someone's actual values should predict not only what they do in their current situation, but what they would do in substantially different situations, given e.g. different information and different expectations for how others behave.
(LessWrongers may ask "what does this add over CEV?" CEV is one possible hypothetical where people are more informed, but is impossible to compute and also not predictive of what people do in actual situations of having somewhat more information while still being under cognitive limitations. Thus, CEV "analysis", unlike conditional/counterfactual analysis, ends up being largely spurious.)
