Understand the evolutionary purpose of happiness and pain
Happiness and pain are evolutionary skills that intervene in biological activities to align them with the 'first purpose' (survival and reproduction).
- Happiness: Acts as a positive reinforcement, encouraging the repetition of behaviors that increase the probability of survival and gene propagation.
- Pain/Fear: Acts as a negative reinforcement, encouraging the avoidance or reduction of behaviors that threaten survival.
Because these responses have been refined through natural selection over vast timescales, following the drive to seek happiness and avoid pain is generally a highly effective survival strategy (estimated 95%+ accuracy).
