 In a similar vein, the common practice of measuring happiness simply by asking people to report explicitly on how “happy” they are is sometimes defended on the grounds that it lets people decide for themselves what happiness is. The reasoning again seems to presuppose, controversially, that self-reports of happiness employ a life satisfaction view of happiness, the idea being that whether you are satisfied (“happy”) will depend on what you care about. Alternatively, the point might be literally to leave it up to the respondent to decide whether ‘happy’ means hedonic state, emotional state, life satisfaction, or something else. Thus one respondent’s “I’m happy” might mean “my experience is generally pleasant,” while another’s might mean “I am satisfied with my life as a whole.” It is not clear, however, that asking ambiguous questions of this sort is a useful enterprise, since different respondents will in effect be answering different questions.
