<p>We argue that there is a fundamental motivation to have one’s life be ‘well-tuned’ to reality, and that this motivation, when successfully achieved, corresponds to a distinct psychological experience. This experience, which we call Life Attunement Experience (LAE), represents a chronic combination of feeling as though one’s life is both “right” and “effective” and has implications for well-being and prosocial behavior. Across five studies, we demonstrate that a measure of LAE explains the relationship between life circumstances indicating successful attunement (higher income, employment, organizational fit, job satisfaction) and general measures of hedonic and eudaimonic well-being. Furthermore, in three studies, we show that LAE has a distinct relationship to prosocial behavior—including objective behavior observed by others—underscoring the importance of this relational element for understanding the truth of a life. These studies combine to provide evidence for LAE’s importance to researchers of motivation in the domains of well-being, morality, and organizational behavior.</p>
