 If life satisfaction attitudes are substantially arbitrary relative to subjective success, then people might reasonably base those attitudes on other factors, such as ethical ideals (e.g., valuing gratitude or noncomplacency) or pragmatic concerns (e.g., comforting oneself). Shifts in perspective might also reasonably alter life satisfaction attitudes. After the funeral, you might be highly satisfied with your life, whereas the high school reunion leaves you dissatisfied; yet neither judgment need be mistaken, or less authoritative.
