   2 corrections applied: Lykken & Tellegen (1996) estimated heritability of well-being at ~80%, not 50%; the 50% figure belongs to the later Lyubomirsky et al. model. | 36% was the overall replication rate across all 100 studies; social psychology specifically replicated at roughly 25%.

   Before

   The set point theory (Lykken and Tellegen, 1996) took this further, arguing on the basis of twin studies that approximately 50% of the variance in subjective well-being is attributable to genetic factors.

   After

   The set point theory (Lykken and Tellegen, 1996) took this further, arguing on the basis of twin studies that approximately 80% of the variance in subjective well-being is attributable to genetic factors.

   Why: Body content was already correctly fixed (David Lykken and Auke Tellegen's set point theory: ~80 percent; Open Science Collaboration: ~25%).

   However the FAQ field's 'What does research say about hedonic adaptation and the set point theory of happiness?' answer still had the stale, unfixed 50% figure attributed to Lykken and Tellegen (the 50% belongs to the separate, later Lyubomirsky et al. model, which the body correctly keeps at 50% for its own model).

   Fixed the FAQ answer to say 80% for Lykken and Tellegen, matching the corrected body text, and re-encoded/verified the faq field.
