Addiction and the Pop Brain
Pardon the long absence. Somewhere between finishing the PhD and moving, blogging fell by the wayside.
Meanwhile, the discourse of around addiction has only been increasing. Today’s New York Times includes a great example of how the neuroscientific language around addiction is encompassing an ever-widening array of phenomena. On today’s menu of new ‘addictions’ is exercise. Actually Kristof’s piece points out just how many substances and behaviors have been shown to ‘light up the brain. I am reminded of Craig Reinerman’s interesting article -- Policing Pleasure. Food, Drugs, and the Politics of Ingestion – where he points out that brain imaging technology has revealed an “embarrassment of riches;” it turns out that many things – maybe even most things -- light up the brain. For me this raises some questions. First, if so many things (Kristof cites illicit drugs, sugar, sex, gambling, money, and altruism) activate our brain centers and “cause addiction,” does the word “addiction” begin to lose its meaning? Second, how does the idea that these substances and behavior “change our brains” affect how individuals understand their own relationship to “addiction.” Kristoff asserts that addiction neuroscience does not undermine free will. But I am not sure how we are to hold onto the idea of free will while simultaneously understanding addiction as a brain disease that changes the brain and erodes the capacity for self-control. All the more reason why need to hear from those labeled "addicts" about what this new brain science means to them.
In any case, today’s NYT piece is evidence of the popularization of neuroscience to explain all manner of personal and social problems. It seems very reminiscence of how genomics was (and often still is) used to explain everything from diseases to personal habits. Barbara Katz Rothman’s book,
The Book of Life: A Personal and Ethical Guide to Race,Normality and the Human Gene Study, offers a great critique of the ideology of genomics as a lens for understanding life, the universe and everything. With pieces like Kristof's gracing the New York Times opinion pages, we may be moving from the “pop gene” to the “pop brain.”
