Similarities: • Both disciplines focus on flourishing and a full, satisfying life. • They agree that wellbeing involves more than mere pleasure or absence of pain, incorporating aspects like purpose and value.

Differences: • Psychology tends to use empirical methods and measurable indicators—often relying on subjective self-reporting and objective data—to assess wellbeing. • Philosophy focuses on normative analysis, exploring what constitutes a well-lived life through values, virtues, and ethical principles rather than solely on empirical evidence. • Philosophical approaches are more about analyzing how one ought to live, while psychological models emphasize understanding and promoting health and happiness as observed in behavior and experience.
