Systems biology of intelligence

Intelligence differences should be studied as an integrated systems problem that combines large‑scale genetics (GWAS/polygenic scores) with multimodal brain imaging and life‑course environmental data, because modest but replicable associations exist across these domains but mechanistic links are still missing. Framing intelligence as a systems biology problem shifts research from isolated correlations toward multi‑level causal models and transparency about limits. — If taken seriously, a systems‑biology framing would change policy conversations about education, screening, and the ethical deployment of polygenic information by highlighting complexity and uncertainty rather than single‑number predictions.
