Complex disorders often reflect two qualitatively different genetic contributions: tradeoffs (variants that increase some social or cognitive advantages while also raising disease risk) and failures (deleterious variation that reduces function across the board). Recognizing and separating these components changes how we interpret genetic correlations (e.g., between schizophrenia and educational attainment) and how research, clinical practice, and social policy should respond.
— If widely adopted, this framing reshapes psychiatric genetics, reducing stigmatizing 'one‑size' models and informing targeted interventions, risk communication, and education policy.

The article cites a recent study that splits schizophrenia genetic risk into a bipolar‑shared component tied to higher educational attainment (tradeoff) and a non‑shared component tied to lower IQ (failure).
