Abstract

Attention-deficit/hyperactivity disorder (ADHD) is a neurodevelopmental condition characterized by symptoms that include inattention, hyperactivity, and impulsivity. Recent research suggests that individuals with ADHD might exhibit higher levels of curiosity, which may be linked to their tendencies toward distractibility and impulsivity. This paper proposes an evolutionary mismatch hypothesis for high trait curiosity in ADHD, positing that 'hypercuriosity', which may have been adaptive in ancestral environments characterized by scarce resources and unpredictable risks, has become mismatched in industrialized societies where environments are more stable and information rich. The theory predicts that individuals with ADHD will demonstrate heightened levels of novelty-seeking and exploratory behaviors, manifesting as symptoms labeled as distract-ibility and impulsivity in modern environments. The paper explores the potential evolutionary benefits of high trait curiosity, the consequences of an evolutionary mismatch, and the implications for research and practice. The limitations of the theory are addressed, such as the need for more targeted research on curiosity in ADHD and potential differences among ADHD subtypes. Future research directions are proposed to refine and test the hypothesis, ultimately contributing to a more nuanced understanding of ADHD and informing the development of strength-based interventions. This theoretical framework offers a novel perspective on the adaptive value of ADHD traits and their manifestation in modern societies.
