Dr. Sonja Lyubomirsky, professor at University of California, Riverside, has devoted her research career to studying human happiness. Existing research suggests that genetics account for approximately 50% of our happiness (Braungart et al., 1992; Lykken & Tellegen, 1996; Tellegen et al., 1988), and circumstances account for approximately 10% (Argyle, 1999; Diener et al., 1999). Lyubomirsky advocates, that this therefore leaves as much as 40% of our happiness to be determined by ourselves and our intentional thoughts and activity, suggesting happiness is a choice we can have control over.
