Creativity Under the Hood: Why Psychiatric Genes Persist Through Evolution

A Nature Communications study links genetic risk for schizophrenia, bipolar disorder, autism, and ADHD to distinct cognitive traits (reaction time, crystallized knowledge, creativity) in European populations, suggesting evolution preserved these variants through pleiotropy and trade-offs where certain cognitive strengths coexist with psychiatric risk. ADHD may relate to faster processing, autism to intense knowledge in specific areas, and relatives of affected individuals are often drawn to creative or technical fields. The work highlights polygenic effects, cautions about embryo selection and stigma, and notes findings are correlational and currently limited to populations of European ancestry, needing broader, diverse data.
