Beyond biological and social normativity: varieties of norm deviation and the justification for intervention

Abstract The most common theoretical approaches to defining mental disorder are naturalism, normativism, and hybridism. Naturalism and normativism are often portrayed as diametrically opposed, with naturalism grounded in objective science and normativism grounded in social convention and values. Hybridism is seen as a way of combining the two. However, all three approaches share a common feature in that they conceive of mental disorders as deviations from norms. Naturalism concerns biological norms; normativism concerns social norms; and hybridism, both biological and social norms. This raises the following two questions: (a) Are biological and social norms the only sorts of norms that are relevant to considerations of mental disorder? (b) Should addressing norm deviations continue to be a major focus of mental healthcare? This paper introduces several norms that are relevant to mental disorder beyond the biological and social. I argue that mental disorders often deviate from individual, well-being, and regulatory norms. I also consider approaches which question mental healthcare’s focus on addressing norm deviations in the first place, including the neurodiversity paradigm, social model of disability, and Mad discourse. Utilizing these critical approaches, I contend that whether mental health intervention is justified depends, in part, on the type of norm deviation being intervened upon.
