Part 7/15:
While discussing intelligence, I emphasize that IQ is a powerful predictor of various life outcomes—health, longevity, occupational status, income, resistance to stress, etc. For instance, a person born into wealth at the 95th percentile of IQ tends to have better long-term prospects than one relying solely on familial wealth. IQ also correlates with physiological robustness; higher IQ individuals tend to have brain structures and functioning that offer some protection against degenerative conditions like Alzheimer's.
