Neglecting the social system: clinical neuroimaging and the biological reductionism of addiction
Abstract
A main strength of neuroimaging and neuroscience is its reductionist focus on the brain. A limitation is that it runs the possibility of ignoring larger social factors. The brain image may not necessarily indicate the brain’s neuroplastic ‘rewiring’ over time from genomic, epigenetic, environmental and social conditions. These factors are all necessary to understand the diverse nature of our brains, especially complex concerns such as addiction. For addiction to emerge it requires an intersection of genetic, environmental and social influences. It is foreseeable to ignore this multi-factorial interaction in the clinical setting when interpreting predictive brain imaging scans. This paper argues that relying too heavily on clinical neuroimaging in the treatment of patients who present a vulnerability to addiction can lead to cases of biological reductionism ignoring the influence social systems have on brain responses
