The Military and Dual Use Neuroscience, Part II

In a previous post, I discussed several promising neuroscience technologies
currently under investigation by the military. Simply knowing that such
technology exists, however, does not in itself dictate a way forward for
neuroscientists and others who are concerned about the possible consequences of
military neuroscience research. In part, the complexity of the situation
derives from the diversity of possible viewpoints involved: an individual’s
beliefs about military neuroscience technology likely stem as much from beliefs
about the military in general, or technological advancement in general, as from
beliefs about the specific applications of the neuroscientific technologies in
question.








Star Trek's Commander Spock was generally ethical in his personal use of directed energy weapons, but not all of us are blessed with a Vulcan’s keen sense of right and wrong (Image).  




With that in mind, I think there are at
least three distinct angles from which an individual might find him or herself
concerned with respect to military neuroscience research. First, there are
those who are opposed to neuroscientific advancement in general due to its
potential implications on identity, moral responsibility, and human nature. Second,
there are those who may be amenable to scientific advancement in general, but
who distrust the military and are therefore suspicious of any technology that may
improve its combat capability. Finally, there are those who have no a priori problem with either the
military or technological advancement, but who have concerns about the ways
that particular technologies may be deployed within a military context.






Technological
Skeptics


Perhaps the most well-known skeptic of biotechnological
advancement is political scientist Francis Fukuyama
, known largely for his 1989 prediction that the fall of the
Soviet Union would usher in the “end of history.”
 While Fukuyama does not oppose all biotechnological
advancement, his 2002 book Our Posthuman
Future: Consequences of the Biotechnology Revolution
 raises concerns about a number of particularly revolutionary
biotechnologies. For Fukuyama, belief in human equality depends upon a consensus
that there are certain essential qualities that unite all human beings. Modern
liberal societies, he argues, are notable in that they attribute essential
humanness to a range of persons – women, for instance, and racial minorities –
to whom such respect has historically been denied. Fukuyama’s fear is that
novel biotechnologies may undermine our collective belief in essential
humanness, and consequently the philosophical basis for political equality. One
area of particular concern for Fukuyama is neuropharmacology, where he predicts
the development of “sophisticated psychotropic drugs with more powerful and
targeted effects” with the capacity “to enhance intelligence, memory, emotional
sensitivity, and sexuality.” Many of Fukuyama’s arguments involve potential
inequalities generated through genetic engineering, but it is not difficult to
extend his logic to many neurotechnologies – for instance, brain-controlled prosthetic limbs,
or transcranial magnetic stimulation – currently under investigation by the military.








Francis Fukuyama, author of Our Posthuman Future 


Fukuyama, and others who hold similar belief
systems, tend to oppose a wide range of military and civilian biotechnologies
rather than military neuroscience per se.
 Such viewpoints, however, hold particular implications for military research if only because DARPA tends to be very, very good at what it does. Historically,
the military has played key roles in the development of microchips, cell
phones, GPS, and the Internet.
This is no coincidence: compared to other research programs, DARPA researchers
enjoy a number of unique advantages.  In Mind Wars, bioethicist Jonathan Moreno points out
that “in the DARPA framework decades of development are acceptable” and that,
according to the DARPA strategic plan, “its only
charter is radical innovation.” That DARPA’s innovation is of this radical kind should constitute a point
of concern for those who believe that neuroscientific research is already
progressing too quickly. While private pharmaceutical firms might develop drugs
targeted to specific symptoms or diseases, DARPA has a particular incentive to
invent drugs that produce what might reasonably be called “superhumans”: drugs
that make humans more intelligent, that increase human endurance and stamina,
or that substantially enhance human physical performance.





Constraining The
Military


Other concerns
stem from the nature of the military itself: as an institution that uses force
to achieve political ends, it is worth asking whether military neuroscience
should be avoided insofar as it renders the military better capable of
achieving these ends.





One area of
concern relates to privacy, where several new technologies suggest a fundamental shift in the nature of state surveillance. In
my first post on military neuroscience, I discussed the Veritas TruthWave EEG
helmet and fMRI lie detection as two especially notable surveillance technologies. While both technologies have significant drawbacks – accuracy in the
case of the EEG helmet, and usability in the case of fMRI – such advances may
nevertheless have worrisome implications. An article on TruthWave
 raises one relevant concern regarding false positives: “When
a person’s life or freedom is at stake, what is an acceptable margin of error?”
In at least some cases – drone strikes on suspected terrorists, for instance, in
which “all military-age males in a strike zone” 
are assumed to be enemy combatants – the military has demonstrated a tendency to set the “acceptable margin of error” higher than it might be in, say, a court of law. The present generation of mind-reading technologies occupy a grey area in the sense that they’re likely accurate enough to be more reliable than intuition, but not so accurate as to reliably avoid false positives. In conjunction with high-stress combat situations or high-priority military objectives, this grey area may become particularly difficult to negotiate. 




Further, it is possible that some innovations in military neuroscience may lower the cost of warfare, increasing the likelihood of intervention and violent conflict. In a 2005 article, Arizona State engineering and ethics professor Brad Allenby suggests that “military prowess, embodied in incredibly potent technological capabilities, acts like a drug, leading to dysfunctionally oversimplistic policy choices,” citing the Iraq war as a prominent example. Innovations in remote-operated robotic weapons – commonly known as UAVs, or “drones” – have already increased the U.S. military’s propensity to engage in combat operations. As one Washington Post editorialist puts it: “The detachment with which the United States can inflict death upon our enemies is surely one reason why U.S. military involvement around the world has expanded over the past two decades.”[1] Military neurotechnology seems poised to reinforce and accelerate this trend. Neurologically-controlled robots, for instance, may drastically improve the effectiveness and flexibility of current UAVs. More broadly, it seems likely that a war we are more likely to win is also a war that we are more likely to fight: in that sense, cognitively-enhanced soldiers, innovative prosthetics, and improved surveillance may all foreshadow a similar future involving a more powerful, more active U.S. military.

Legality And
Other Issues


Many problematic aspects of new military
neuroscience technologies derive simply from the fact that they are new. Consequently,
many current international legal frameworks designed to constrain warfare may
not apply to new neuroscience technologies.





Concerns of this sort are discussed at
length in the U.K. Royal Society report. 
For instance, newly-developed pharmaceuticals may have uses
in the interrogation of suspected terrorists or prisoners of war. Coercion of
POWs is outlawed by the Geneva Convention, as are medical procedures contrary
to “the rules of medical ethics.” The extent to which the Geneva Convention
applies to terrorists, however, has been a matter of dispute
.
Given recent reports of coercive pharmaceutical use at Guantanamo Bay,
concerns of this nature are particularly salient.







As is often the case, key questions of ethics and policy hinge on exactly how similar our universe is to “24” (Image). 


The deployment of novel chemical
incapacitants in combat raises complex legal questions as well. The Chemical Weapons Convention (CWC), an
international agreement ratified by the U.S. in 1997, bans the use of chemical
weapons in conflict. At times, however, the CWC can be ambiguous: according to a U.K.
Royal Society report on neuroscience and conflict, parts of the CWC may be interpreted to allow “the use
of toxic chemicals to enforce domestic law extra-jurisdictionally or to enforce
international law.” Insofar as international law and extra-judicial enforcement
of domestic law are themselves open to interpretation
, the CWC may leave the door open to some offensive uses of
chemical weapons.





Finally, the use of cognitive-enhancing drugs to aid friendly soldiers is complicated by a provision of the
Uniform Code of Military Justice requiring servicemembers “to accept medical
interventions that make them fit for duty.”
 On one hand, novel enhancement drugs might provide safer alternatives to
currently-employed stimulants such as amphetamines,
thereby lowering the health risks to military personnel. Alternatively,
however, safer drugs could lower the costs associated with coercive drug employment,
resulting in a lower threshold for coercion of military servicemembers.





It’s Not All Bad


Depending on your perspective, of
course, what I have called “concerns” may in fact be substantial benefits. I'm certain that leading transhumanist Nick Bostrom
 sincerely looks forward to to brain-computer interfaces, and that pro-military foreign policy analyst Robert Kagan wholeheartedly supports technologies that sustain U.S.
military dominance. More generally, neurologically-enabled prosthetics have obvious
benefits for disabled persons,
and civilian spin-offs of many military neurotechnologies hold considerable
medical and commercial promise.

Nevertheless,
there is a large enough breadth of military neuroscience research, and an
similarly diverse set of ideological positions from which to criticize it, that any
given individual is likely to find something
in DARPA that they consider worthy of concern. Coming to such a conclusion,
however, is only a first step, and the second step: “what to do about it?” – does
not have a simple answer. To a large extent, those who publish on the
implications of dual-use neuroscience technology have made similar suggestions.
The Bulletin of Atomic Scientists, for instance, recommends greater interdisciplinary
discussion on dual-use technology, and a 2003 Nature editorial suggests that “researchers should perhaps spend more time pondering the
intentions of the people who fund their work.” While these publications are
certainly correct in identifying a need for additional discussion on dual use
technology, I’ve personally found myself frustrated at the lack of specific,
practical suggestions in much of the literature. 







It is Jonathan Moreno who, to my knowledge, has offered the most concrete suggestions for coping with the implications of military neuroscience. In Mind Wars, Moreno warns neuroscientists against rejecting all military funding, arguing that such a position would only push DARPA research into greater secrecy. If military neuroscience research is inevitable, he reasons, it is better for it to be done transparently (and therefore in some sense democratically) than for it to be done underground, where it cannot be criticized simply because it is not known about. Instead, he recommends that neuroscientists attempt to influence public discussion on military neuroscience in a similar fashion to scientists who opposed nuclear weapons use during the Cold War. From a regulatory perspective, Moreno further recommends the creation of a “neurosecurity equivalent to the National Security Advisory Board for Biosecurity,” a committee that would include scientific input from a range of disciplines, including neuroethics. Moreno is also optimistic that at least some in the defense industry might take ethical issues seriously, citing one defense contractor who has “had ethics advice from the very beginning [of a brain-machine interface project].” 





I don't agree with all of Moreno's suggestions - I think, for instance, that there's something to be said for the symbolic value of refusing to work on a project that you disagree with - but I admire his attempt to provide concrete solutions to an issue that defies simple analysis. In a 2012 article in PLoS Biology, Moreno and Michael Tennison suggest that “discussions in themselves will not ensure that the translation of basic science into deployed product will proceed ethically... These considerations must be embedded and explored at various levels in society: upstream in the minds and goals of scientists, downstream in the creation of advisory bodies, and broadly in the public at large.” Whether and how the ethics of military neuroscience are “embedded and explored” have yet to be determined, but the answer to these questions will have significant implications for the control and ultimate consequences military neuroscience research.






[1] Though it’s worth noting that the author, John Pike of Globalsecurity.org, considers this to be basically a good thing, writing that “the large-scale organized killing that has characterized six millenniums of human history could be ended by the fiat of the American Peace.”

Physical vs. Cognitive Alterations: Is All Fair in the World of Anti-Aging Enhancement?






On March 28, Dr. Rommelfanger, Assistant Director of Emory's Neuroethics Program, gave a talk to the Nu Rho Psi group about the ethics of neuroenhancement technologies. These technologies can be anything from Adderall to interventions that raises IQ. This talk got me thinking about how the normal human aging process is critical in the way that a person views themselves and others. 










Aging now battled with complex technologies. Across the world, doctors routinely perform appearance altering operations, even to the point of giving someone an entirely new face (like this man), which certainly come with psychological consequences. While face transplants are an extreme example, other cosmetic procedures, like Botox injections to relax wrinkles, are performed millions of times a year.  But what about procedures to alter cognitive function? Is neuroenhancement technology ready to become mainstream, or is there some inherent feeling that altering the brain is off limits?






 In the view of Arthur Caplan (Director of the Center for Bioethics at UPenn), "Messing with the brain is unnatural because the brain is the seat of who we are. To change it is to change our identity."1 Loss of identity is a frightening prospect. As the population ages (the median age in America jumped almost 2.5 years from 1990-2000)2 and technology progresses, the interest in brain enhancement for the purposes of retaining cognitive abilities known to decline with age will grow. Is altering our brain function really much bigger of a step from altering our physical bodies, or is it mostly fear of the unknown?


Francis Fukayama states, in a speech called “Our Post-human Future”, “Human rights are based on a certain understanding of human nature.”3 Neuroenhancements are often understood as bestowing an unfair advantage on those who are enhanced in ways that plastic surgery could not, to the point of potentially changing this “human nature”. But can’t physical features have profound effects on “human nature”? In a study done by Timothy Judge and Daniel Cable, it was found that taller people make more money at an average of almost $800 per year per inch above average.4 Isn’t this an unfair advantage?






  In terms of neuroenhancements, even caffeine could be seen as enhancing your brain function, yet coffee is a widely accepted and properly consumed substance. When I have a long paper to write, I can be seen in the library with a gigantic cup of coffee feverishly typing away – is keeping myself awake and alert giving me an advantage over others (or cheating), and if so, should it be banned? What if I were an executive in my 60s using supplements to keep my brain “young” to hold onto my career? As Fukuyama points out, society moves in a generational pattern, and if six generations of people are competing for the same jobs, this will seriously change the fabric of society and competition. But isn’t life in general full of unfair advantages (money, physical traits, etc.)…how do we say what is “fair” or “natural” and what is not?


Both plastic surgery (aesthetic) and neuroenhancements (cognitive) are used as a way to battle the aging process, a huge determinant of identity. Humans are mortal, and while we are all faced with this as reality, some prefer to think that mortality doesn’t have to limit our existence. There are even individuals, like Ray Kurzweil5, a leader of the transhumanism movement, who believe that the time is coming when people won’t have to die at all because computers will have progressed to a point where we can upload our minds onto them. 






This may seem extreme, but it is unsurprising that many would seek to slow the aging process, whether by appearing younger or attempting to keep the brain functioning at a high level.


We have all been bombarded with images of youth and beauty, urging us to buy the latest anti-aging products. Plastic surgery has a large client base of those seeking the latest in wrinkle treatment, and even something as simple as hair dye is a weapon in the fight to appear young. In the United States alone, over 119,000 facelifts were performed in 2011 (up 5% from 2010)6, and this and other age-defying procedures like Botox have been increasing rapidly throughout the world.7









In Western society, youth is highly valued, and age is often viewed as a sign of weakness or uselessness.9 However, East Asian cultures have traditionally revered their elders and looked to them as a source of wisdom.8 While many Asian countries, like South Korea and Japan, have been quick to embrace Western culture and anti-aging aesthetics like plastic surgery, it seems their reverence for the aged and the process of aging may lead to a decreased likelihood to try brain enhancements.10 Why would someone who already possesses the wisdom and respect that comes with age need an anti-aging upgrade?


Countless vitamins and supplements claim to boost brain function, and most advances in medicine are sought in the diseases of aging. Invasive surgical processes already being attempted for diseases like Parkinson’s (deep brain stimulation)11 and Alzheimer’s (implanting genetically modified cells into the brain)12. It may not be that much of a stretch to see a world in which all aging people, not just those with diagnosable diseases, may seek treatment to keep their brains “young”. Cognitive decline will no longer be seen as “normal”.






Neuroenhancement is simply unnatural, you may say. That it may be, but humanity has been fighting nature for a long time. Have no hair? Wear a wig. Vision poor? Here are some glasses. Can’t hear? Cochlear implants might be just the thing for you. The problem with this line of reasoning is that all of these things can be seen as technologies designed to grant a person “normal” abilities, even if they fit in the category of neuroenhancements. We assume that any given human will “normally” possess the ability to see; we do not assume that they will have a genius level IQ or the ability to live to age 200. With the development of neuroenhancements, might it be possible that we create a world in which non-enhanced people are considered abnormal or that enhanced older people are being “enabled”?


Many groups are quick to attack neuroenhancements as technology to be feared and censored. For instance, Leon Kass wonders whether we will doom future generations to become slaves to machines and whether we fully recognize the immense potential for evil that some of these technologies can create.13 In terms of brain-enhancing drugs, some doctors wonder whether or not the safety of long term use has been adequately tested.14 While these are legitimate concerns deserving of careful thought, I believe most of this skepticism can be largely attributed to a fear of the unknown. Most of us have seen the movies where robots or genetically engineered humans take over the world (Gattaca, I, Robot), leaving the “normal” people at best outcasts and at worst akin to some kind of lowly beast in the eyes of those in power. 






While some may be frightened by these prospects and the idea of enhancing technology, others might be tempted to run full speed ahead into the world of brain enhancements. The technologies with which humans can transform their bodies are major and varied, and many are already being employed; should enhancement of the brain really be off limits?
