Intelligence and early life mortality: Findings from a longitudinal sample of youth
The current study examined whether adolescent IQ predicted risk for mortality by the age of 32. Analyses of data from the Add Health revealed that IQ was related to mortality risk, such that respondents with relatively lower IQs were significantly more likely to experience early life
mortality when compared to respondents with relatively higher IQs. This association remained statistically significant even after controlling for a host of covariates such as race, gender, involvement in violent behaviors, levels of self-control, and poverty. The average IQ of deceased respondents
was approximately 95, whereas the average IQ of living respondents was about 100.
