Variance-First Psychology: How Standardization Paradigms Can Undermine Humanistic Capacities That Built Civilization

Human progress has historically depended on cognitive and behavioral diversity – the varied ideas, risktaking, and novel thinking that drive innovation. Yet contemporary psychological research often emphasizesstandardized laboratory tasks, narrow diagnostic criteria, and conformity to normative performance,potentially pathologizing the very high-variance traits (e.g., intense focus or novelty-seeking) that enabledhuman creativity. We review evidence that psychology’s findings are predominantly drawn from Western,Educated, Industrialized, Rich, and Democratic (WEIRD) populations using artificial tasks with limitedecological validity , and that high-variance dimensions associated with neurodivergence (such as ADHDsymptomatology and novelty-seeking) can foster exploration and creative insight . Ethical paradigmsemphasizing autonomy and context (e.g., the UN Convention on the Rights of Persons with Disabilities)further support research that values diverse abilities. In response, we propose a Variance-First researchagenda: one that prioritizes naturalistic, field-embedded measurement (e.g., ecological momentaryassessment), broad sampling (population registries), and cultural-evolutionary models to quantify thesocietal value of behavioral diversity. We outline methods (including randomized interventions and targettrial emulation analyses) to test specific hypotheses about variation and innovation, and we presentillustrative results to demonstrate these plans. Finally, we discuss implications for ethics and public policy,arguing that acknowledging human variation will enrich scientific theory and better align practice withhuman rights and welfare.Keywords: WEIRD bias; ecological validity; neurodiversity; ADHD; exploration–exploitation; culturalevolution; ecological momentary assessment (EMA); digital phenotyping; ethics; capability approach.
