The neuroethical importance of reasons bypassing

Recently, the storied Russian cybersecurity firm Kaspersky Lab carried out a formal threat analysis of deep brain stimulation (DBS) and its supporting infrastructure (1). The basic setup for DBS is simple: an electrode is stereotaxically implanted in a patient’s brain, and thin wires are fed under the skin to a device that delivers occasional pulses of electricity. Over 100,000 people have been implanted with DBS electrodes, primarily for movement disorders but also to ameliorate symptoms of other neurological and psychiatric diseases (2). Newer models allow for remote control of the stimulation parameters via Bluetooth, either from a computer or a smartphone (3), and it is this development that prompted the threat analysis.
That a device relying upon wireless information technology is vulnerable to hacking is hardly newsworthy. What distinguishes this situation from everyday hacking are concerns over so-called ‘brainjacking’ – the ability of attackers to exert malicious control over one’s brain by taking control of the DBS implant (4). I suggest that apprehension over brainjacking is symptomatic of what might be termed ‘the worry over reasons-bypassing’ and that this concern is a hallmark of much that is neuroethically problematic. As a result, it is worth taking a few moments to sketch out what the issues are and how it applies more generally to the field of neuroethics.
But what if we encounter an outside influence that is either so powerful, or covert, or in some other way so insidious that the opportunity to ‘reason things out’ is missing? In other words, what if an external influence bypasses reason, denying us the opportunity to reflect on the relevant issues? Such an eventuality should properly act as a red flag for further inquiry, and one might go so far as to say that this is a hallmark of much that is neuroethically problematic. A few examples serve to illustrate the point.

A similar issue arises when considering the propriety of engaging in pharmacological moral enhancement. In a recent study, Jona Specker, Maartje Schermer and I investigated public attitudes towards using pharmacological and non-pharmacological means to combat bullying (11). We presented members of the public with a series of vignettes that described a situation in which a child was being bullied at school. One group of people were presented with a vignette in which the bully would be given a pill composed of the natural hormone oxytocin which increased empathy- a form of moral bioenhancement – and thereby decreased bullying. Another group was presented with an identical vignette except that the ‘treatment’ was playing a video game that once again increased empathy and thereby decreased bullying. As we expected, people strongly preferred treating the bully with the video game rather than the pill. But we also noted that one of the concerns expressed by the public about the use of the pill to ameliorate bullying was that the bullies would have only been instrumentally ‘corrected.’ People perceived pharmacological moral enhancement as solving the problem in some utilitarian sense but worried that the individuals who are the targets of the drugs have not learned how to navigate the world properly. The pill – a natural hormone – acts in a fashion that is reasons-bypassing, and because their behavior is driven by the drug rather than by their understanding of what is morally proper; they found this problematic. [That the public are so neuroethically attuned is of interest in and of itself.]

Lest we think that high technology is required to bypass reason, there are worries that nudges (small changes to the environment that influence the likelihood of one decision or another) might also be reasons bypassing. Although nudging doesn’t immediately come to mind when one thinks of neuroethical issues, it bears all the relevant features: the target of nudging is the brain, the crux of the issue is decision-making, and the worry is over usurping autonomy.
The classic example of a nudge is the decision to be an organ donor. If the default option is set to opting in – that is one needs to check a box on one’s driver’s license renewal to become an organ donor – only 42% decide to do so. When the default option is to opt out – checking a box on the application is required in order not to be an organ donor – 82% become donors (12). While it is true that the person being nudged has the option of making whatever choice they wish to make, the design of the nudge so substantially biases the outcome that, at least in a statistical sense, much of the decision is already made for them. Especially pernicious is the fact that the ‘nudgee’ is unaware that the environment has been altered so as to ‘stack the deck.’ Hence, many nudges swerve towards being reasons bypassing, and it is specifically this fact that makes them neuroethically suspect (13).
How big of an issue is reasons-bypassing? We have seen that three different technologies – one involving invasive neurosurgery, another involving routine psychopharmacology, and a third employing a strategy of simply changing default options – all share reasons-bypassing as a fundamental neuroethical objection. Especially when we move from the clinic to the world of everyday life, we find many opportunities for worry about reasons-bypassing technologies. The entire suite of worries over neuromarketing (14) – be it via classic advertisements on TV or more subtle influences on our decision-making presented to us via social media – are imbued with worries over reasons-bypassing. For these reasons, I would argue that reasons-bypassing serves as one of the major features of neuroethical concern. I welcome you, the reader, to reflect on other ways in which reasons-bypassing might evoke neuroethical concerns and share them in the comments.
