Dr. Peter B. Reiner speaking at the Peter Wall Institute of Advanced Studies International Roundtable We are our brains, October 2013.
The current issue of the European Journal of Risk Regulation has the proceedings of a symposium on nudging, and it contains a set of insightful papers. The introduction by the editor says it best.
The EJRR starts the new year by hosting a pioneering symposium devoted to one of the latest policy innovations that is currently experimented in the United Kingdom and the United States: the ubiquitous, yet controversial, Nudge. This idea originates from the homonymous, 2008 best-selling book published by the economist Richard Thaler and the legal scholar Cass Sunstein. By building upon the findings of behavioural research, they refute the classic economic assumption that “each of us thinks and chooses unfailingly well”1 and they advocate the need for public authorities to nudge people to make decisions that serve their own long-term interests without however removing their right to choose.
At a time in which governments are taking considerable interest in the use of nudging, we have asked some of the leading authors who have already contributed to the literature surrounding the regulatory innovations, generally referred as New Governance, to share their ideas on this appealing regulatory approach.
In his opening essay, Nudging Healthy Lifestyles, Adam Burgess provides a critical assessment of the introduction of behavioural, nudging approaches to correct lifestyle behaviours in the UK. His thought-provoking analysis triggered a lively debate that has been framed along the subsequent essays signed by On Amir and Orly Lobel, Evan Selinger and Kyle Powys White, Alberto Alemanno and Luc Bovens.
The article by Alberto Alemanno, Managing Editor of the European Journal of Risk Regulation is a fulsome account of the propriety of nudging in the case of tobacco control (recently highlighted by Roland on these pages); that nudging in this instance overcomes many of the objections that are raised in the other contributions to the symposium.
I also liked Selinger & White’s analysis of nudging in the context of Brad Allenby and Dan Sarewitz’s insight on the three levels by which we should view technological fixes (as articulated in their excellent book The Techno-Human Condition, which I have written about before). In particular, they point out the naiveté of only considering shop-floor arguments, a topic we will return to again.

Although the topic of cigarette packaging regulation may not leap immediately to mind when one thinks “neuroethics,” this Bob Greene opinion piece over at CNN nonetheless touched off a stimulating discussion among some of us at the Core recently. The neuroethics connection, in fact, struck us as quite natural: our group has researched (and blogged about) the ethics of “nudging” frequently of late, and, as I worded it when I first emailed the article around, “certainly the images at issue here are a kind of behavioural nudge.” The question that we grappled with was whether the kind of nudge that the graphic warning labels provide is warranted in the case of cigarettes. And, indeed, that discussion called my original characterization into question. Do these labels truly constitute a nudge – a subtle biasing technique that makes a particular option more cognitively accessible than another while preserving the freedom to choose between them – or are they something more akin to a “shove?”
As with any highly politicized issue, the question of whether cigarettes ought to be labeled with disturbing imagery is likely to be filleted into oblivion by pundits, bloggers, legal experts, economists, et cetera, et cetera. All I hope to do here, then, is sketch some ways in which the view from neuroethics – informed as it is by philosophy and the cognitive sciences – can shed some interesting and hopefully useful light on the question.

Abstract: Deep brain stimulation (DBS) has been proposed as a potential treatment of drug addiction on the basis of its effects on drug self-administration in animals and on addictive behaviours in some humans treated with DBS for other psychiatric or neurological conditions. dbs is seen as a more reversible intervention than ablative neurosurgery but it is nonetheless a treatment that carries significant risks. I will review preclinical and clinical evidence for the use of DBS to treat addiction to determine whether its use is currently warranted, making the case for caution. Severely addicted persons who try and fail to achieve abstinence may, however, be desperate enough to undergo such an invasive treatment if they believe that it will cure their addiction. History shows that the desperation for a “cure” of addiction can lead to the use of risky medical procedures before they have been rigorously tested. In the event that DBS is used in the treatment of addiction, I will examine the minimum ethical requirements for conducting such a trial.
About the speaker: Dr. Carter is an NHMRC Postdoctoral Fellow in Public Health at UQ. He is particularly interested in the impact that neuroscience has upon notions of autonomy and responsibility in addiction, the use of coercion and the capacity to consent in addiction treatment, as well as the use of novel neurological technologies to treat, and possibly, prevent addiction. Dr. Carter has published numerous articles on these issues, as well as reports for the who, the European Monitoring Centre for Drugs and Drug Addiction, and the Australian Ministerial Council on Drugs Strategy.
Over at The New Republic, Sally Satel, psychiatrist and resident scholar at the American Enterprise Institute, recently reviewed the controversial book Addiction: A Disorder of Choice by psychologist Gene Heyman. Heyman’s thesis is that conventional wisdom about addiction being a ‘disease’, or perhaps a ‘brain disease’, is incorrect. Satel quotes Heyman by saying, “that the idea [of] addiction [as] a disease has been based on a limited view of voluntary behavior.” Accordingly, addiction is not an “irresistible act”, as he claims the term ‘addiction’ implies, and is in fact a “disorder of choice”. [Note: I have not read Heyman’s book, so I will not comment on the book directly]. Indeed, Satel conveys Heyman’s position as one that is in opposition to perspectives from powerful public figures that support the view that “Addiction is a Brain Disease, and it Matters.” Satel agrees with Heyman’s position, namely that if addiction is a disease, it is a disease the person chose for herself.
Satel’s review of Addiction prompted a response from writer Sascha Z. Scolbic and Peter Scolbic (TNR’s executive editor), who argued that Satel was puting up a “straw man” argument. [See Satel’s reply to the Scolbic’s here].
According to Dr. Michael Krausz, the LEEF Leadership Chair in Addiction Research, chronic substance abuse and mental illness are of critical concern and pose significant challenges, especially when they are co-occurring. Dr. Krausz recently brought his international expertise in concurrent disorders – the dual diagnosis of mental illness and drug addiction – to the University of British Columbia to address the crisis in Vancouver’s Downtown Eastside where addiction, psychiatric illness and homelessness are rampant. Hailed as the poorest postal code in Canada, the Downtown Eastside is a microcosm of social problems where overdose and suicide are the leading causes of death.
At the “Neuroethics of Addiction” conference Dr. Krausz’s message was clear – treatment availability and access to those is need is seriously lacking in Vancouver. Dr. Krausz stated that he views the current situation as ethically problematic. For instance, he stressed that people with addiction and mental health issues have the highest unmet need for treatment but are often excluded from medical care, have increased rates of mortality and are amongst the most stigmatized and socially marginalized of groups. They suffer from many health-related burdens including HIV/AIDS, Hepatitis C, suicide, addiction-related cancers and homelessness. Nevertheless, a general lack of treatment and support is available. It it Dr. Krausz’s hope that the BC Centre for Excellence in HIV/AIDS will serve as a model for the creation of a similar Centre for Excellence, to provide focused resources and structures to facilitate state of the art addiction and mental health research in Canada.
Dr. Krausz described the current situation in Vancouver’s Downtown Eastside as being in “crisis mode” and lamented that emergency care is an insufficient reaction to the increasing needs of the community. He stated that part of the issue is the misconception that addiction is a moral issue – bad people making poor choices and until the public at large realizes that addiction is their problem too, no real change will take place.
Addiction is a brain disease. This is undeniably a bold and controversial statement and one which usually elicits varied reactions ranging from denial and skepticism to wholehearted agreement. The lack of consensus means that when Canada’s “neuroscientist in chief” is defending this view, people to sit up and pay close attention. During his recent talk as part of our “Neuroethics of Addiction” workshop, Dr. Anthony Phillips, the newly appointed scientific director of the Canadian Institutes for Health Research’s (CIHR) Institute for Neuroscience, Mental Health and Addiction (INMHA), explored how the brain networks and chemistry change as a result of repeated drug abuse. Dr. Phillips explained that people who abuse drugs are in the process of changing their brain chemistry (mainly through fluctuations in dopamine levels), which has semi permanent effects on decision-making processes.
From the data Dr. Phillips presented, it is clear that the brain plays a role in addiction. The ‘reward network’ and dopamine-glutamate system function pathologically such that basic needs such as food are ignored and seeking a particular drug is prioritized. But is addiction only a brain disease? I think it would be shortsighted to conceptualize the condition in that way. In addition to brain activity, socioeconomic, psychological and political factors, among others contribute to onset of the addictive behavior as well as to the disease course itself. This is not to say that investigating the neuroscience of addiction and addictive behavior is not a worthy endeavor. After all, Dr. Phillips expressed hope that research on the neuroplasticity (the brain’s ability to change itself) may have important implications for treatment of addiction. The contributions that science can make towards understanding and managing addiction are undoubtedly valuable. It is important, however, to acknowledge the complexity of the condition and avoid reductionist perspectives on addiction.
