 The discussion thus far has assumed that people can be wrong about how happy they are. Is this plausible? Some have argued that (sincerely) self-reported happiness cannot, even in principle, be mistaken. If you think you’re happy, goes a common sentiment, then you are happy. This claim is not plausible on a hedonistic or emotional state view of happiness, since those theories take judgments of happiness to encompass not just how one is feeling at the moment but also past states, and memories of those can obviously be spurious. Further, it has been argued that even judgments of how one feels at the present moment may often be mistaken, particularly regarding moods like  anxiety.[13]
