 Such findings have led some philosophers to seek out alternatives to hedonism in hopes of establishing a more empirically stable underpinning for well-being: in particular, the idea that well-being consists in life satisfaction. The most prominent psychologist in this field is Ed  Diener[11]  whose Satisfaction with Life Scale asks participants to agree or disagree with statements such as, “I am satisfied with my life” and “If I could live my life over, I would change almost nothing.” These questions seem to get at more stable and significant features of life than hedonic assessments in terms of pleasure and pain, and one might expect the responses to be more consistent and robust. However, two problems arise. The first is that participants’ responses to life satisfaction questionnaires may not be accurate reports of standing attitudes. Fox and Kahneman (1992), for instance, showed that, especially in personal domains people seem to value (friends and love life), what predicts participants’ responses is not recent intrapersonal factors but social comparison. Someone who has just lost a friend but still thinks of herself as having more friends than her peers will tend to report higher life satisfaction than someone who has just gained a friend but who still thinks of himself as having fewer friends than his peers.
