The truth in social construction
Central strands of biological psychiatry, such as the Research Domain Criteria championed by Thomas Insel, aim to identify mental illnesses with genetic and/or neural dysfunctions. Such approaches are justified by the mismatch between psychopathologies picked out by descriptive criteria (such as those used by the fifth edition of the Diagnostic and Statistical Manual of Mental Disorders) and neural correlates: patients presenting with the same symptoms may share little at the neural level, while those who share dysfunction at the neural level may exhibit quite different symptoms. Biological psychiatry is typically understood as opposed to social constructionist approaches to mental illness. This chapter argues that because symptomatology and disorders of neural circuits fail to match, biological psychiatry needs to embrace social construction, broadly understood. The differences at the level of symptomatology will often be explicable by differences in patients’ individual histories and social and cultural settings. The notion that social construction and biological psychiatry are mutually exclusive arises from an inchoate and incoherent feeling on both sides that only the second offers a physicalist explanation of mind and behaviour; in fact, a social explanation can ultimately be cashed out in physicalist terms. Nevertheless, systematicity of the kind sciences seek will need to be sought at the level of representations, as well as at the level of the brain, since cultural and social factors are unlikely to be able to be cashed out in terms of physical natural kinds.
