I recently got interested in a new field https://en.wikipedia.org/wiki/Cognitive_epidemiology
Cognitive epidemiology is a field of research that examines the associations between intelligence test scores (IQ scores or extracted g-factors) and health, more specifically morbidity (mental and physical) and mortality. Typically, test scores are obtained at an early age, and compared to later morbidity and mortality. In addition to exploring and establishing these associations, cognitive epidemiology seeks to understand causal relationships between intelligence and health outcomes. Researchers in the field argue that intelligence measured at an early age is an important predictor of later health and mortality differences.
I decided to scout the academic literature. Here’s some for those also curious.
Special issue of Intelligence, 2009, about cognitive epidemiology.
