 Two other objections are more substantive, raising questions about whether life satisfaction has the right sort of importance. One concern is whether people often enough have well-grounded attitudes of life satisfaction or dissatisfaction. Evaluating one’s life as a whole can be a complicated business, and there is some question whether people typically have well-defined attitudes toward their lives that accurately reflect how well their lives measure up relative to their priorities. Some research, for instance, suggests that life satisfaction reports tend to reflect judgments made on the spot, drawing on whatever information comes readily to mind, with substantial influences by transient contextual factors like the weather, finding a dime, etc. (Schwarz and Strack 1999). Debate persists over whether this work undermines the significance of life satisfaction judgments, but it does raise a question whether life satisfaction attitudes tend to be well-enough grounded to have the kind of importance that people normally ascribe to happiness.
