Faculty and members of the Advisory Board of Neuroethics Canada, a group of distinguished neuroscientists, ethicists, and community leaders, stand together in this time of COVID-19 to emphasize the importance of global cooperation.
While the closure of physical borders is a necessary means to curtail the spread of the coronavirus, intellectual borders must remain open to international collaboration among scientists and society to reverse the fragmentation caused by the pandemic.
It is through worldwide cooperation that stigma and discrimination will be suppressed, cures discovered, and preventive measures to new threats implemented for a safer future for all people.
This blog post discusses some of the key findings from the article “The Impact of a Global Pandemic on People Living with Dementia and their Care Partners: Analysis of 417 Lived Experience Reports , paper here).
It is without question that the COVID-19 pandemic has greatly impacted our daily lives. From new health policies to months being on lockdown, we have had to adapt to the rapidly changing circumstances within the last year and a half. Remember when every day necessities were becoming scarce and the difficulty in trying to find a roll of toilet paper? More importantly, as the pandemic progressed, there were increased concerns surrounding available hospital beds and ventilators [1,2] and the allocation of resources including vaccines and therapies to combat the virus [2,3]. While the entire world has had a handful of shared experiences, some have been more vulnerable to the virus and the regulations set in place.
During the earlier days of the pandemic, we learned that older adults were at a higher risk of contracting the virus, especially those living in long-term care facilities, including people living with dementia. They were restricted from going out, attending regular health care services, receiving home support, or accessing community supports and social networks. Families and care partners also had difficulties in caring for their loved ones, as some were unable to physically visit them in a long-term care home. As this continues to be an unprecedented time, it is important to understand the experiences and needs of the dementia community.
What we did
With an ongoing collaboration with the Alzheimer Society of British Columbia, we at the Neuroscience, Engagement, and Smart Technology (NEST) Lab developed a survey to explore the lived experiences of people living with dementia and their care partners during the pandemic. In this survey, we touched on four different themes including (1) information and resource needs, (2) caring for someone living with dementia during the COVID-19 pandemic, (3) mental health and well-being needs, and (4) the use of technology for social connection during the pandemic. We distributed the survey between June and August 2020 and received 417 responses (395 care partners and 22 people living with dementia).
What we found
Information and resource needs
Figure 1 shows the locations from which our participants were receiving their information about COVID-19. With so many sources of information during the pandemic, our participants found that the information they accessed were helpful in terms of maintaining their own health (74% of care partners, 86% people living with dementia) and a period of social distancing (70%, 77%). They found that the information they accessed was either somewhat or very stressful (29%, 23%), neither stressful or reassuring (23%, 23%), or somewhat or very reassuring (48%, 54%). In terms of needs, care partners wished to have learned more about care options including long-term care and respite care, while people living with dementia wanted to learn more about self-care during the pandemic.
Figure 1. “Where have you been receiving information about the COVID-19 pandemic?”
Caring for someone living with dementia
The focus of this section in our survey was to identify the main concerns of care partners during the pandemic. While there was concern for every care partner scenario described in the survey, the five major concerns were having more responsibilities as a care partner, access to therapy and/or a vaccine for COVID-19 in the future, having the person they care for be infected with COVID-19, the person that they care for having difficulty understanding COVID-19 and the health regulations set in place, and having themselves be infected with COVID-19. Figure 2 presents other areas of concern for these care partners.
Figure 2. Care partner concerns.
Mental health and well-being
An increased period of social distancing and being on lockdown affected the mental health and well-being of those living with dementia and their care partners. People living with dementia were restricted in their home, not being able to go out to get groceries, attend regular health care services, or even access community supports. With this in mind, we uncovered that the pandemic had increased our participants’ stress overall (58%, 62%), and they had felt left out (63%, 81%), isolated (74%, 81%), and lacked companionship (70%, 76%). To manage this stress and maintain their well-being, participants said that they spent time talking to friends and family, walking around the neighbourhood, watching television, and engaged in household activities.
Technology and social connection
As many in-person activities were suspended and some transitioned to a virtual setting, we were interested in whether people living with dementia and their care partners were utilizing technology for social connection. Even though there were increased feelings of isolation and lack of companionship during the pandemic, our participants were able to socialize and connect with others through a cell phone/smartphone, on devices such as laptops and tablets, as well as home phones. However, only 19% of care partners and 36% of people living with dementia felt that using technology to connect with others felt the same as interacting with them in person. There is something to be said about the quality and impact of having in-person interactions and the impact it can have on one’s mental well-being.
Our survey took the opportunity during a challenging time to explore the real life experiences of people living with dementia and their families and care partners. With this, we were able to identify some actionable priorities for services such as those provided by the Alzheimer Society of B.C. to better support the dementia community during a pandemic. Since the publication of our results, the Alzheimer Society of B.C. already implemented some of the suggestions and findings in their service delivery. Moving forward, there will be plans to implement long-term changes to address the needs of this community and to better manage the care for older adults and people living with dementia.

In April 2021, Neuralink released a video of Pager, a macaque monkey, playing a computer pong game with their brain . The N1 Link, a fully-implanted neural recording and data transmission device with 1024 electrodes, allowed Pager to play pong by using patterns of their neural activity to model the movements of a computer cursor . There are many ethical considerations associated with brain-computer interfaces and their use with animals, such as physical harm and psychological distress . Here, we will focus more generally on the ethical challenges of the brain-computer interfaces Neuralink is developing and the global attention that Pager has drawn to neuroethics.
Elon Musk founded Neuralink in 2016 with the mission of merging humanity with artificial intelligence. Neuralink aims to achieve this through designing and building wireless, implantable brain-computer interfaces to help improve treatments for neurological conditions such as Alzheimer’s disease and dementia . As shown by Pager’s ability to play a game using their mind only, Neuralink is quickly progressing closer to its goal of enhancing brain function by integrating artificial processing .
The ongoing development of neurotechnology is pulling some key neuroethics topics into the limelight . As Neuralink’s video of Pager gained popularity online, more and more individuals began expressing interest in the potential implications of neurotechnology . On social media platforms, people are engaging in neuroethics-related discussion threads , bringing increased attention and perspectives to topics often discussed in the field. Examples of topics include data privacy concerns, safety issues, and considerations around how brain technology may influence behaviour .
Renewed public interest in the ethical challenges of these technologies stresses the importance of ethical and socially responsible research and development . One key ethical consideration is the tradeoff between potential benefits and adverse effects of neural implant devices. As the use of neurotechnology may move from remediation to enhancement in the future, this risk-benefit calculation may become more complicated and must be further scrutinized .
The use of brain-computer interfaces also raises questions about who owns an individual’s brain data. Important issues include who has the right to write data to implanted devices and how developers can ensure privacy and security during the use of their devices . Whether or not BCIs can be developed to enhance what a person can achieve, there are already concerns around how social equity and access will continue to be impacted. Further developments will likely continue to exacerbate health inequalities, making these questions even more important to answer .
In the future, brain-computer interfaces may transform approaches to treating neurological conditions and even move to performance enhancement. It has been suggested that the success of these technologies may depend on multiple factors . These components may include the willingness of innovators to prioritize ethical innovation drawn from interdisciplinary expertise , and regulations and policies that prioritize individual and societal wellbeing.

In collaboration with Canadian Childhood Cannabinoid Clinical Trials, Neuroethics Canada conducted a series of research projects to investigate ethical, legal and social issues surrounding medical cannabis. We studied news media representations of medical cannabis, conducted interviews with clinicians, and held virtual workshops to garner a greater understanding of the perspectives of key stakeholders, and to make recommendations for future medical cannabis research, regulation and use.
Ethical issues at the forefront of news reporting on medical cannabis: Capturing the focus of multiple formats of news media coverage on medical cannabis is essential to understanding how public opinions and public policy are shaped. We studied traditional and alternative news media messaging surrounding medical cannabis and health. Analysis revealed that key ethical, legal and social (ELS) issues were the main focus of both traditional and alternative news articles. Alternative news articles covered ELS issues more in fewer articles, and reported on fewer themes per article. Overall, access was found to be the dominate ELS issue. Multiple factors impacting patient access, such as institutional regulations and supply of products, were reported on in both traditional and alternative sources (Figure 1). In traditional news coverage, institutional gatekeeping of patient access declined significantly post-legalization of adult possession and use of medical cannabis; by comparison, there was no change in alternative news pre- and post-legalization with regard to gatekeeping, although coverage of the access factor of product supply increased post-legalization (Cannabis Act, 17 October 2018). There was limited coverage of issues specific to exceptional populations, including children with neurological and medical disorders and Indigenous peoples. See Gunning and Illes, Coverage of medical cannabis by Canadian news media: Ethics, access and policy, International Journal of Drug Policy, 97, 103361 (2021); and response to publication, International Journal of Drug Policy, under review.
Harm reduction approach for medical cannabis in the care of youth and children: The use of cannabis for medical purposes by youth and children is expanding. However, supporting evidence and federal and local regulations are lacking. Understanding clinician perspectives of this landscape is key for addressing access barriers, and for supporting safe, appropriate use. We interviewed Canadian clinicians practicing in areas related to paediatric medicine including neurology, oncology and palliative care. Clinicians discussed barriers to patient access, chiefly obstacles in the authorization process such as considerations around supply, quality and cost of products. The need for facilitating open, honest clinical communication between patients, caregivers and clinicians was described as essential for ensuring informed consent. As with all other treatment decisions, clinicians described considerations that could mitigate risks, such as life-limiting prognosis and number of tried and failed conventional therapeutic options. Further, they expressed that more methodologically-sound research is essential for expanding medical applications of cannabis. Overall, the discourse aligned with the principles of harm reduction: pragmatism, humanism, harms, and prioritization of immediate goals (Figure 2). Gunning et al., Canadian Medical Association Journal, under review.
Building trust in the tense world of medical cannabis: We convened a two-day virtual workshop to discuss ethics and medical cannabis for children and youth in healthcare. Three main topics were covered in each session: (1) the current scientific and regulatory landscape of medical cannabis; (2) surrogate decision-making and assent; and (3) social and political culture of medical cannabis. In attendance were members of the public, ethicists, clinicians, researchers, policy makers, patient representatives, and industry representatives. Despite having a medical cannabis access program in Canada for two decades, participants expressed disappointment that there is still a large amount of uncertainty around medical cannabis due to a lack of data and poor data translation. Also highlighted by participants was the importance of clinicians building trust with patients by demonstrating their trustworthiness in clinical consultation. Respecting patient informed choice, assent and dissent, and understanding and addressing the root cause of clinician hesitancy to authorize were described as ways clinicians can facilitate trust with patients and their caregivers. Participants discussed historical and ongoing stigmatization of medical cannabis and medical cannabis users, particularly of people who are already marginalized within the healthcare system. There were calls for more strength-based research with Indigenous youths’ and communities’ to understand their perspectives on medical cannabis and health. Gunning et al., in preparation.
Our work, including media analyses, interviews, and workshops, highlighted three key areas that will be critical to addressing ongoing issues in the study, regulation, authorization and use of medical cannabis: (1) continued examination of ethics issues surrounding medical cannabis; (2) acquisition of evidence using innovative, adaptive study designs and diverse knowledge systems; and (3) public consultation and engagement with key stakeholders.
Infographic resources for pediatric Drug Resistant Epilepsy
Ask yourself, “would pamphlets or posters be a good means of sharing information for blinded patients?”. Hopefully your response falls somewhere along the spectrum of, “of course not” to “that’s not ideal”. And you’d be right; when creating a resource for a particular group, it’s essential that their needs be considered to ensure the information is shared in a meaningful and functional way. This is true in all domains, be it websites, videos, or printed resources. If the resource is inaccessible to the group you wish to share your research with, then its usefulness is limited to academic discussion and it will not be effective in the real world.
Despite efforts to elucidate guidelines on how to best engage with the public, research shows that many patient education resources aren’t very palatable to the average person. Issues with technical jargon, lack of visual aids, and incomplete information all contribute to the inaccessibility of an educational resource. These issues can be compounded when sharing findings on complex topics such as neurotechnological treatments for pediatric drug resistant epilepsy (DRE). Ultimately, when creating resources from one’s research, the main concern should be that it is readable, understandable, and useful to those who look to access those resources (1).
The reading age for a text is measured by its readability, which is a proxy score on how easily it can be read and processed by the reader. Readability commonly assesses the use of familiar words, density of syllables, and length of sentences to determine its score. The American Medical Association (AMA) suggests that all patient resources be written at or below 7th grade reading level, the average American reading level (2). However, studies on resources curated for ophthalmology, lung cancer, and dementia found that nearly all patient education materials produced exceeded these AMA recommendations, leading to materials that were beyond the general populations ability to interpret (3,4,5). In areas where patient’s may be suffering from cognitive deficits, such as epilepsy, clarity in written resources is paramount. Yet patient education websites for epilepsy surgery show no greater care for readability than other fields, with the majority written at an excessively difficult reading level (6). This pattern of low readability suggests that presently available patient resources are not accessible to the common patient, and may be contributing to lower levels of health literacy.
While readability is an excellent way to assess whether your audience can read your resource, it doesn’t quite capture whether they can comprehend the information it is sharing. The Patient Education Materials Assessment Tool (PEMAT) developed by the Agency for Healthcare Research Quality measures understandability in terms of content, word choice and style, use of numbers, organization, layout and design, and use of visual aids (7). These metrics are useful for determining how well patients can process a resource’s information and identify the key messages. Applying these measures to current resources reveals how short of the mark they fall in communicating information to patients. In a review of diabetes education materials, only 16% met criteria for understandability (8). Neurosurgery resources were similarly rated with a notable lack of summaries, main messaging, and visual aids (9). This finding is corroborated by another study on epilepsy decision-making, which notes more than half of reviewed patient education materials lacked visual aids entirely (6). Taken together, it’s clear that much improvement is needed to promote clearer communication of research findings to patients.
The final piece of the patient resource puzzle is ensuring the information a resource is sharing is useful to the reader.Meaning, can they apply they information they learned to benefit their healthcare journey? The idea of usefulness aligns well with the PEMAT measure of actionability: “consumers of diverse backgrounds and varying levels of health literacy can identify what they can do based on the information presented” (7). In practice, patient education resources fall short once again, with only 1 diabetes resource meeting criteria for actionability, and the majority of neurosurgery resources failing to identify next steps or tools to help patients take action (8,9). Usefulness is also limited by inclusion of all relevant information, and in cases where decision-making is needed it is important for patients to be aware of all relevant risks and benefits to make informed healthcare decisions. Yet, nearly half of reviewed resources for epilepsy surgery neglected to touch on risks and benefits, with some providing biased information in one way or the other (e.g. discussing risks or benefits but not both) (6). It is startling to see that the vast majority of carefully crafted patient resources are not proving to be useful to the patients they serve.
A Neuroethical approach to Patient Education Resources
So, how do we make patient resources that are more engaging for patients? An excellent case study in this area are the infographic resources curated alongside research on decision-making for pediatric drug resistant epilepsy.
The large NIH funded project “Informing Choice for Neurotechnological Innovation in Pediatric Epilepsy Surgery” has several arms of research consisting of clinical trials,media analysis, youth interviews, family interviews, caregiver interviews, and genetic testing interviews (10-15). Though the methods for each arm of research varied, the methodology for creating patient-centered infographics stayed consistent.
In neuroethics, the patient’s rights, privacy, and voice are held in high esteem, and the NIH in particular has stated that engagement with the public in research is key. Bidirectional dialogue is encouraged to ensure that patients can engage with the research, and researchers can stay abreast of public desires, concerns, and health literacy (16). This bidirectional dialogue was employed in the development of the infographics, seeking patient and caregiver input at various stages throughout the process to guarantee the patient voice was incorporated and to ensure the resulting infographics were readable, understandable, and useful.
Infographic development process
A value-guided iterative approach was used for the development of all the infographics. The key findings of the research were extracted and summarized, informative headers and take-home messages were drafted. A word document was created with the information in plain text within a table, to resemble the proposed infographic layout, and was then reviewed by caregivers and research collaborators to ensure accuracy and understandability. Once through this initial process, the infographic was prepared, refined by the researchers, and sent to caregivers for review via a short 15-minute survey. The survey gathered information about clarity of main points, conciseness, engagement, visual appeal, and usefulness.
The survey also gauged respondent’s prior knowledge, willingness to share the infographic, and preferred format to engage with the resource. With feedback in hand, the final version of the infographic was designed and uploaded to the study’s page with a QR code included in the design to allow for further feedback and refinement in the future.
On the sample infographic included to the side you can see the clear title, summary, research design, and action item (highlighted in red).
Readability was ensured through simple language use informed by PEMAT measures and feedback from caregivers. Understandability was ameliorated through the use of clear design, layout, and imagery. Nesting topics underneath key themes to retain a sense of cohesion. Both risks and benefits were addressed to better inform the reader of all relevant information and the take home messages summarize the useful pieces of information the reader can take away to apply in their healthcare journey.
Now that we have a framework for how to create and improve patient education materials, future researchers will be able to follow in our footsteps and create patient resources that are accessible. Such accessibility in the form of readability, understandability, and usefulness are highly important, as many North Americans do not possess high levels of health literacy (17,18). Health literacy comprises all the necessary skills to access, process, and comprehend health information in order to make informed healthcare decisions (19). Researchers have amassed a wealth of data on health, healthcare, and treatment options that have the potential to greatly impact the lives of many suffering with health conditions. In order to unlock that potential, patient voices need to be acknowledged and incorporated when creating resources. In this way we can bridge a crucial gap between bench and bedside, creating a more equitable and accessible healthcare system for all.

This blog post discusses some of the key findings from the article “Socially Assistive Robots as Mental Health Interventions for Children: A Scoping Review” published in the International Journal of Social Robotics (2020, paper here).
What is a social robot?
Social robots are small robotic devices that are capable of social interactions, such as cooperation, instruction and play. The robots can be shaped like animals (e.g., Aibo – the robotic dog (Fig. 1(a)) or characters (e.g. humanoid robot Nao (Fig. 1(b)). Among other functions, social robots can play a therapeutic role (1), serve as companions (2) and aid in education (3,4). One of the application areas of social robotics is therapy for children with autism spectrum disorder. In this domain, robotic companions have the potential to improve a variety of behavioural outcomes, including social and language skills (5). Social robots are also used with older populations. For example, robots like Paro (Fig. 1(c)) are being used in elder care settings. This baby harp seal lookalike helps reduce loneliness and agitation among residents (6).
A new mental health intervention for children
Since social robots seem to have a positive impact on mental health in different populations, there is a growing interest in using them as a tool to promote and improve mental health among children. As a result, a number of studies are being conducted to test social robots in this relatively new domain. In the Neuroscience Engagement and Smart Tech (NEST) Lab, we collected and analyzed the existing research studies which investigate the use of social robots to improve children’s mental health (10), to get a fuller view on what interventions are being tested and how.
What we know: Feasibility and short-term effects
Using social robots to benefit children’s mental health is a new and rapidly developing field. Hence, the majority of currently available studies are intended as means of exploring what is possible and what could be effective in the future. The studies usually include a single session with the robot, which shows only short-term outcomes of the interaction. While the evidence does not allow for drawing strong and long-term conclusions, the studies in our sample demonstrate that various robotic interventions are feasible. We know that social robots can be introduced and deployed in therapy, clinical and other settings. But perhaps the most crucial aspect of determining whether robotic companions could be successful, is the fact that children participating in the studies usually showed a positive response to the robots and were engaged in the interaction, e.g., distraction during vaccination (11). This positive reception makes the developments in the use of social robots promising.
What we still need to learn: Effectiveness and social impact
To be able to draw conclusions about the effectiveness of robotic interventions we need more evidence. Future research in this field needs to systematically address well-focused questions around specific outcomes (e.g., stress reduction). Additionally, potential social impacts of the robots should be more carefully considered. Robots are intended to be introduced into different environments as social entities. For example, a robot present at a hospital to distract children during medical procedures will likely affect others around the child such as parents and nurses. Moving forward, we need to learn more not only about specific social robot interventions that can be helpful, but also about how introducing social robots into new environments will affect social dynamics.
What about ethics?
Conducting child-robot interaction research comes with unique ethical concerns. In our scoping review of the literature, we found that the majority of studies in the sample provide only generalized statements about the assent process used (10). Transparency about how the robot is introduced and described to young participants is crucial, as children of different ages may have different beliefs about the animacy of robots. Other notable ethical considerations include attachment and deception. For example, children could experience distress when the robot is taken away or mistreated (12). The key to proactively addressing these ethical issues could be using participatory approaches throughout the research process. Working together with children and parents will help minimize the risk and maximize the benefit of future social robot mental health interventions.

This blog post discusses some of the key findings from the article “Prioritizing Benefits: A Content Analysis of the Ethics in Dementia Technology Policies” published in the Journal of Alzheimer’s Disease (2019, paper here).
A new era of dementia care
From tracking devices to social robots, technology is rapidly transforming the scope of dementia care. Persons living with dementia and their caregivers can now choose from a wide range of innovative technologies to assist with everyday activities, symptom management, and more. With potential benefits such as increased autonomy and enhanced safety for persons living with dementia (1), new technologies are continuously being developed and entering the market.
Despite the excitement of innovation, the promising benefits of dementia technology must not be the only ethical implication to consider. Although monitoring technologies such as video surveillance can keep older adults safe, this may be at the cost of compromising privacy and independence. While companion robots may show potential in enhancing well-being and connection in older adults (2), this often comes with an expensive price tag. These diverse ethical implications are important for older adults to consider so they adopt technology that best aligns with their needs and values.
The question is, how are these ethical implications communicated to the dementia community through public policies?
The guidance of public policies
Alzheimer associations around the world create public-facing policies to guide the adoption and use of technology in dementia care. Given the wide array of ethical implications in need of consideration, policies play a critical role in raising the ethical issues of care technology to the dementia community. However, we found that the quality and ethical content of these policies can greatly vary, particularly around what ethical implications are being most and least discussed with the public (3).
What we found: Policies prioritize benefits
In the Neuroscience, Engagement, and Smart Tech (NEST) Lab, we analyzed the ethical content of 23 international policies using the four principles of biomedical ethics (4): beneficence, non-maleficence, autonomy, and justice (Fig. 1).
What we found was that nearly all policies (96%) discussed the benefits of using technology such as increased independence, improved social contact, and enhanced quality of life for the person affected by dementia (3). However, this near-perfect score was not matched by the other ethical principles that raise the potential risks and harms associated with using dementia care technology (Fig. 2)
Themes of justice, for example, were discussed in 74% of the policies, followed by themes of non-maleficence at 52% and autonomy at only 43% (Fig. 2). This lack of comprehensive discussion surrounding the risks and potential harms of dementia care technology is critical for users. Understanding ethical considerations such as cost, privacy, and consent are imperative for people affected by dementia to make well-informed decisions about their care.
Reshaping dementia technology policies
As dementia care technology continues to rapidly develop, so should policies that shape their adoption and use. To maximize the current and future benefits of dementia technologies, policies need to be reworked so that they are in the best interest of the dementia community. Important to this is the inclusion of not just benefits, but the potential risks and harms associated with dementia care technology. Persons with dementia, caregivers, and family members need to be actively engaged in the policy-making process to ensure patient-centred guidance in public policies.
A guide to adopting new technology in dementia care
Based on our findings, we disseminated a public resource to guide the adoption of new technologies in dementia care. Here are 10 questions for older adults to consider when adopting a new technology:

This blog post discusses some of the key findings from a poster presentation for the 2021 annual meeting of the American Academy of Neurology (abstract here) and published in the Journal of Child Neurology (2021, paper here).
Neurotechnologies that can change certain functions of the brain may help children with a type of epilepsy that responds poorly to anti-seizure medication (drug-resistant epilepsy). However, there are important differences in the way that parents and doctors make treatment decisions about them.
For parents and caregivers of children with drug-resistant epilepsy (1), treatment choice goes beyond just the direct effect of the treatment on the child’s seizures. They also consider their child in context of the world and their overall quality of life (2). For doctors, treatment choice focuses on the evidence of effectiveness and the seizures themselves (3,4). Understanding both the shared and different decision-making priorities for these groups requires deeper insight into the values that drive them.
The promise and uncertainty of neurotechnologies
Neurotechnologies use innovative techniques to alter brain activity in two main ways: electrical stimulation (i.e., neuromodulation) or the removal of diseased tissue. Modern examples include responsive neurostimulation and laser interstitial thermal therapy. These treatments are gaining in popularity because of their perceived benefits, such as reversibility and limited invasiveness.
Given the special developmental needs of children, we wanted to better understand the trade-offs of benefit and risk. We talked to parents and doctors caring for children with drug-resistant epilepsy across Canada and the USA. We asked them to identify the most important factors they consider when weighing novel neurotechnologies against traditional neurosurgery.
For parents, quality of life is key
When asked about new forms of neurotechnology to treat their child’s epilepsy, parents highlight the benefits including – but also beyond – seizures. Specifically, parents identify quality of life as a crucial factor. This includes life factors such as independence and freedom from the side effects of medication.
“Can they [our child] hold down a job? Can they have a house? Can they get married and have a life? To me, that was important,” said one parent.
Doctors mainly discuss seizure freedom as a measure of success. As one doctor stated, it’s important to consider multiple factors, including quality of life, but that “the big [measure] is seizure control, decreased seizure frequency, and then seizure freedom.”
Not all information is equal
For doctors, scientific evidence is the main factor in considering a new procedure, and to prioritize safety and trust. Introducing novel treatments is therefore challenging (5), because they lack clear evidence while they are being studied, especially in children.
Parents struggle to meet all kinds of information needs. They describe spending hours learning online from a range of sources–from academic articles to blog posts. The credibility and readability of these online resources varies greatly, and they report that reliable sources of information are sometimes difficult to identify.
One parent commented, “[Once the information is] on the internet …we have to decipher whether it’s real.”
Many parents suggest that it would be helpful to receive objective materials directly from hospitals or epilepsy centers.
Preserving trust for novel treatment decisions
Novel treatments disrupt conventional decision-making paradigms. Understanding the different ways medical professionals and parents approach treatment decisions can ease the experience of choosing treatment.
Parents maintain a high degree of trust in their doctors and medical team. Incorporating the different perspectives of families, young patients, and physicians preserves trust and supports inclusive clinical practice.

Electroencephalographic (EEG) monitoring provides critical diagnostic and management information about patients with epilepsy and seizure mimics. Admission to an epilepsy monitoring unit (EMU) is the gold standard for such monitoring in major medical facilities worldwide. In many countries, however, access is challenged by limited resources compared to need. Triaging EMU admission in these circumstances is generally approached by unwritten protocols that vary by institution. In the absence of explicit guidance, decisions can be ethically taxing and are easy to dispute.
Drawing upon the limited triage literature from neurology and then moreso from various areas of medicine more broadly, my mentors and I developed an ethically-grounded two-component approach to EMU triage (Randhawa et al., under revision, 2021). The strategic component identifies three targets to guide improvements in EMU wait list infrastructure at the institutional level: (1) accountability to patients and public to foster transparency, (2) engagement of clinicians and administrators to achieve process improvements, and (3) empowerment of waitlist managers to promote active waitlist management strategies (see Figure).
The principled component applies an essential balance of three key moral philosophies to triage at the patient level. First, prioritarianism promotes the needs of the most ill, defined by seizure frequency and severity; however, it may also include subjective measures such as suffering. Second, utilitarianism maximizes the overall utility of resources, promoting the greatest benefits for the most people. If patients are having frequent seizures, they are more likely to benefit from EMU evaluation (utility) and are considered sicker (priority); therefore, these first two ethics principles work together. The principle of justice promotes equality by considering other relevant contextual factors such as patient’s ability to self-advocate and length of wait. This principle provides further refinement to the triage process. For example, patients who are disabled by frequent seizures may be unable to advocate for themselves to obtain a sooner admission despite the high utility and priority. As such, justice provides further impetus for accelerated admission.
These principles will be weighted differently depending on several contextual factors, such as the availability of adequate resources: high-resource settings favor prioritarianism; low-resource settings favor utilitarianism. Other factors affecting the use of these principles include patient and public values, clinician preferences, and objective metrics available to guide these decisions.
The approach we propose can inform site-specific process improvements and further revisions based on data generated at individual institutions. While much work remains to be done to explore and test implementation of the model, it provides a starting point in transforming implicit thinking about ethically-fraught circumstances related to EMUs into explicitly principled ones.

A central set of behavioural principles governs the inability of humanity to consider complex, compound, and collective threats like climate change—and now, COVID-19—as moral problems.
Here, I will briefly comment on the moral analogy between the two crises using four psychological factors to explain climate inertia: cognitive complexity, uncertainty-generated optimism, tribalism and scapegoating, and temporospatial separation. By establishing how both global crises intersect in remarkably similar ways in terms of moral behaviour, I will discuss how research on COVID-19 public health adherence can promote future collective action on the climate issue.
Cognitive complexity: As stated in a 2012 article by Markowitz and Shariff (1), people struggle to form strong moral intuitions in response to complex problems requiring cognitively-effortful processes to understand.
Climate change is a quintessential example: it non-linear, consisting of non-proportional inputs and outputs, abrupt changes and tipping points, and feedback loops. These components interlock in complex ways that are not fully understood, leading to significant misconceptions among the general public. Exponential growth bias (Fig. 1.), the cognitive tendency to linearize trends, leads to gross underestimations of the threat posed by exponential progression and leads to hazardous policy delays. Moreover, climate change lacks a simplifying moral framework—one that involves intentionally caused harms to which brain regions responsible for moral judgment are most sensitive (2). Instead, climate change is commonly attributed to natural causes, with some people denying any degree of human involvement.
COVID-19 demonstrates the same nonlinearity. An infectious disease is a textbook example of exponential growth (Fig. 2): within a period of one month, COVID-19 infection rates rose from 58 to more than 150,000 in the USA alone (3). Given the natural origins of the virus, COVID-19 lacks clear human perpetrators. People may be ignorant of their role in disease transmission especially if they are asymptomatic. This is only one complicating factor in COVID-19’s complex transmission including long incubation periods and multiple risk factors. The misinformation epidemic further impedes health guidelines and fosters public mistrust in scientific and public authorities. Overall, underestimation of the viral spread at early stages led to dangerous delays in policy action: a mistake estimated to cost approximately 36,000 lives in the USA (4).

Uncertainty-generated optimism: Uncertainty is another defining feature of the climate crisis. Due to the complex dynamics that underlie environmental change, our best predictions for the impacts of climate chance inevitably fluctuate (Fig. 3). Well-intentioned use of probabilistic phrases such as “likely” and “very likely” in mainstream climate reports to encompass these predictions however can mediate poor risk perception and encourage the overestimation of positive future outcomes (6).

The COVID-19 crisis is also highly uncertain, especially at its outbreak due to limited and rapidly-changing information. This increased uncertainty and scepticism, compounded by viral misinformation (8) on social media and the internet. For the COVID-19 pandemic, the lack of past experiences to anchor predictions hindered accurate risk appraisal. This is evident in the disparity in preparedness between countries that had residual awareness from the 2003 SARS epidemic compared to countries facing the pandemic anew (9). Novel research suggests that risk perception is directly correlated with engagement in protective health behaviours during COVID-19 (10). Thus, modelling effective climate risk communications to amplify scientific clarity remains crucial.
Tribalism and scapegoating: When faced with blame, individuals tend to invoke cognitive biases that downplay their own culpability and scapegoat others (11).
As the tragedy of the commons unfolds around environmental issues, some countries refuse to make economically-limiting emissions cuts unless major competitors do the same (12). The concept is tied to moral tribalism: personal, political, and national identity that contribute to discordant perspectives and in-group favouritism. As individuals strain to understand beliefs that conflict with their own, political polarization of climate change threatens beliefs about scientific validity, threat-level, and personal responsibility.
Similar biases are relevant to the COVID-19 pandemic. Public health officials, immigrants, and Asian communities are frequent targets of scapegoating (13, 14, 15). Support for mitigation measures is divided among ideological camps in polarized countries like the USA, reflected in polls (15) and public media. This isolating rhetoric amplifies social divisions and withholds focus from collective responsibility.
Temporospatial separation: A major problem in framing the climate issue is that it is distant, with the most severe impacts befalling not present polluters, but the global poor, future generations, and non-human species. Prosocial moral judgment, still adapted to ancient life in small tribes, favours in-groups rather than psychologically-distant out-groups (16). Certain areas in the social brain activate to a greater extent for proximal individuals, boosting emotional association, empathy, and altruistic motivation. The suffering of distant individuals, including oneself in the future, fails to activate these regions and blunts empathic responses (17). Consequently, many people may believe there is mutual exclusivity between present-day benefits such as socioeconomic development and future-oriented climate change mitigation measures.
This concept drives the largest wedge between the analogy, as COVID-19 is clearly a more short-term phenomenon with visible present-day consequences. However, if the timeline of the pandemic is made relative so that we look at its early stages, it is clear that both crises still present similar challenges. A virus originally localized in East Asia did not elicit countermeasures in countries that had yet to report their first case. One of the main counterarguments against stringent COVID-19 regulations is economic losses, including high unemployment rates. The virus is also sharply unequal in impact. It may be deadly for vulnerable populations, while others may experience little to no symptoms. Systemic inequities exacerbate health inequalities, making certain groups more susceptible to the pandemic, including immigrants, racial minorities, and those of low-socioeconomic status. However, adherence to public health recommendations during the pandemic is partly predicted by pro-sociality towards these aforementioned at-risk populations—highlighting the importance of individual awareness of the collective (18).
The tale of two crises
To avoid the most severe effects of climate change, humanity must reach net carbon neutrality by 2050 (19, 20), requiring rapid, drastic, and systematic changes across societal levels. However, we display an overall apathy towards the economic and lifestyle sacrifices necessary to do so (21).
COVID-19 is a largely different story: lifestyle and economic interests have taken a back-seat to public health. The large part of society is proving itself capable of prioritizing and rapidly adapting to public health measures, sacrificing normal activity like work, school, and social gatherings. There exists a clear priority, one that has led to significant beneficial health outcomes—a study published in Nature (22) estimates that anti-contagion measures averted approximately 495 million infections in China, South Korea, Italy, Iran, France and the United States. Why then, has the world effectively adapted to an infectious disease, but remains unsuccessful in making similar sacrifices for the climate? Perhaps, it is because of the immediate impact of COVID-19 compared to climate change, or the perception that the pandemic is time-limited whereas climate change requires long-term mitigation efforts. While inherent differences make it difficult to distinguish underlying factors, moral judgment may play a central role.
Scientists are addressing these questions in the form of novel research regarding the socio-behavioural motivators of public health adherence. This includes data on prosocial emotions, trust in scientific and governmental institutions, and risk perception (23). By identifying the behavioural factors behind successful public health campaigns, corresponding insights may be drawn for climate mitigation. Altogether, the findings may be consolidated into public communication strategies that translate diffuse challenges into clear mental models that support individual commitment to collective action.
The United Nations Economic Commission for Africa has stated that “COVID-19 lessons offer hope for global efforts to address climate change impacts” (24). Indeed, climate change researchers and communicators alike are recognizing the potential that the COVID-19 pandemic has for providing a template for climate response. This does not entail reframing pandemic response as a precursor for climate change mitigation efforts, but rather clarifying the behavioural motivators underlying successful public health interventions, and connecting these motivators to public communication strategies.
An interdisciplinary approach that combines the knowledge of behavioural scientists, environmental scientists, and communications experts is essential for any effective response to the climate crisis. Policymakers should support behavioural measures, remove structural obstacles to adherence, and promote individual liberties and justice within public ethics strategies.
To echo environmental ethicist Dale Jamieson, the climate problem cannot be solved with only scientific or technological advances. Instead, the solution concerns our values:
It is about how we ought to live, and how humans should relate to each other and to the rest of nature. These are problems of ethics and politics as well as problems of science. (25)
The rapid reaction to the COVID-19 crisis shows that we are more than capable of overcoming psychological roadblocks in order to confront shared challenges. The why behind this outcome is a research gap that we have an ethical obligation to fulfill—for our own sake and that of future generations.
After all, although climate change is much more prolonged a crisis than the current pandemic, it is no less urgent.
