Introduction
The UK’s management of the Covid-19 pandemic is generally acknowledged to have been poor (
Arnold et al. 2022;
Health and Social Care and Science and Technology Committees 2021) leading to 148,897 excess deaths by December 2021 (
WHO 2021), and a burden of long-term health problems that has damaged population well-being, productivity (
Mortimer-Lee & Pabst 2022) and the economy (
ONS 2021). This was despite the UK having an advanced research and development infrastructure, a public and national health service free at the point of need, and a large and sophisticated scientific advisory system that functions during emergencies to inform the government (SAGE: Scientific Advisory Group in Emergencies).
Explanations for the poor outcomes in the UK and other countries have been discussed in scholarly articles (e.g., Baum
et al. 2021, Sachs
et al. 2022) and in the evidence submitted to the UK’s independent public Covid-19 Inquiry led by Baroness Hallett.
1 These include lack of pandemic preparedness; the state of UK public services including depleted and fractured public health, hospitals, care homes and local government; poor working and living conditions for many; a government that was ill equipped to lead or to understand and act appropriately on scientific advice (
Scally et al. 2020); major failures of public procurement (
McKee 2020); and questions about the effectiveness of the translation of scientific evidence into policy and practice.
Effective infection control requires that people break pathways of transmission between them; for Covid-19 it was quickly established that this requires distance between people, and as the aerosol route was recognised, requiring well-ventilated or filtrated shared spaces. Since the distancing measures were highly disruptive, impacting disproportionately on those already disadvantaged, complementary measures were, and still are, needed to minimise their wider impact on health, education and wellbeing (
McKee & Hiam 2022). Since social distancing practices were very unfamiliar to the UK population of 2020, effective methods of leadership and communication to all parts of society were required (
Independent SAGE 2020a;
SPI-B 2020a).
During crises, governments call on the advice of scientific experts to help them understand and manage them and their impacts. SAGE was established in 2020 to inform the government about the latest scientific understanding relevant to pandemic management. From a behavioural science perspective, much of the advice was aimed at enabling governments to effectively and speedily support people to behave in ways that would reduce viral transmission. Many in the behavioural group within SAGE (SPI-B) perceived a mismatch between the behavioural advice provided to government, and the government's policies and practices. Of course, governments take into account many factors other than scientific advice when making decisions, but the gap between advice and observed policy and practice was notable. Examples included a failure to adequately engage, consult and listen to communities most challenged in adhering to edicts, communicating in very general rather than behaviourally specific terms (for example, the vague ‘Stay Alert, Control the Virus’ message) and taking a punitive rather than enabling, positive approach to supporting people to adhere to rules.
The provision of independent, accessible and transparent scientific advice is important not only to inform government policies, but also to provide a trustworthy source of information for the public, media and other organisations. Trust in governments and authorities has been shown to be a key ingredient in enabling populations to follow government guidance, and hence to effective management of pandemics (
Fancourt et al. 2020). However, there is relatively little published empirical work examining the processes and outcomes of scientific advisory committees in crises (
Donovan 2021). The processes and outcomes of advisory groups in emergencies warrant analysis and empirical study. The UK’s Covid-19 Inquiry terms of reference and scope did not explicitly include the manner in which scientific advice was provided (
UK COVID-19 Inquiry 2022).
This article raises questions about some of the methods of translating scientific knowledge and thinking during Covid-19, from the perspective of having served to advise policy-makers outside an emergency situation over decades and having been part of both the first SAGE created for the H1N1 (‘swine flu’) pandemic of 2009–10 and in the 10th activation of SAGE for the Covid-19 pandemic from 2020 onwards.
2 It is written as a contribution to the discussion about what can be learnt from the UK Covid-19 experience and taken forward to ensure that scientific advisory processes are in the best shape to contribute during the next crisis, which may not be far in the future.
It addresses three questions:
1.
Was the model (framework) for translating scientific advice to policy-makers as effective as it could have been?
2.
Could the science and its implications for policy and practice have been communicated better to the public?
3.
Do scientists have a social responsibility to discuss policy implications of scientific evidence and to challenge politicians when their statements or behaviour go against prevailing evidence?
This paper does not address the ways that advice is presented (for example, terminology, length, complexity), nor how advice is implemented downstream (such as how the complexity of factors, including scientific evidence, influences policy decisions); both are associated with large empirical and theoretical bodies of work. Rather, it focuses on models and frameworks for translating scientific evidence to potential users. To provide context, examples of failures of the UK Government in managing Covid-19 are provided, along with possible reasons for an apparent mismatch between scientific advice provided and policy decisions taken. A summary of the government’s scientific advisory process via SAGE is also provided as background.
Examples of failures in the UK government’s management of Covid
‘One of the most important public health failures the United Kingdom has ever experienced’ was the verdict on the government’s decisions in a House of Commons Committee report on ‘lessons learned’ in September 2021 (
Health and Social Care and Science and Technology Committees 2021). This referred to both the government’s decisions on, for example, lockdowns and social distancing, and also on the advice that informed them. There are many examples of apparent failures of scientific advice finding its way into government action, possibly the most egregious being the delays to lockdown both in March 2020 and again in September of that year as the second wave started, despite SAGE advising earlier action on both occasions (SAGE
2020a,
2020b). The loss of life due to the first lockdown delay has been estimated as 34,000 (
Arnold et al. 2022). I summarise three other examples of scientific advice–policy disconnect.
The first example is the poor government messaging that happened throughout, exemplified by the switch of slogans to guide people’s actions from the clear ‘Stay at Home’ to 'Protect the NHS' and 'Save lives' to the nebulous ‘Stay alert’ to ‘Control the virus’. SAGE was never consulted on this and, indeed, the ‘Communications’ scientific advice was removed from the brief of the behavioural science group within SAGE (‘SPI-B’)
3 which had previously been SPI-B&C to include communications. This change was because the UK Government Chief Scientific Adviser (‘CSA’) considered that communications was part of operations and logistics (
Rubin 2023), suggesting that he did not sufficiently recognise that there was an important body of scientific evidence and theoretical base underpinning communications.
The third example illustrates a failure to implement what the WHO Director General in his 16 March 2020 briefing on Covid-19 referred to as the ‘backbone’ of pandemic management, an effective Test, Trace and Isolate system (
WHO 2020). Isolating when symptomatic or testing positive for Covid-19 is essential for breaking transmission routes. Data from the CORSAIR study,
4 a national weekly survey of 2000 people set up to measure pandemic-related behaviours and the influences on them, showed that in 2020 fewer than 30 per cent of those symptomatic were isolating from other people (
Smith et al. 2021). The main predictors and reasons for this low rate of isolation were having low income, insecure jobs and suffering financial hardship (
Smith et al. 2021). This was in the context of the UK having one of the lowest rates of sick pay in Europe, being only 16 per cent of average pay (
Cominetti et al. 2023). When presented with these data, SAGE advised that sufficient financial support be given to those who needed to self-isolate to avoid hardship (
SPI-B 2020b).
Since the CORSAIR study had been commissioned by the Department of Health and Social Care to inform strategy, the hope was that the government would respond positively to the SAGE advice based on these data. However, the government response was to offer financial support that was less than the living wage to a restricted group of people, with a cumbersome application procedure, with associated low take-up and financial hardship (
Reed et al. 2021). On the other hand, a measure about which there had been no consultation with SAGE/SPI-B was introduced, imposing fines of up to £10,000 for those not self-isolating when symptomatic or testing positive. The result was predictable: not only did it not solve the problem of low rates of self-isolation, but few people came forward for testing when symptomatic, only 30 per cent according to the CORSAIR study (
Smith et al. 2021).
Another example of a policy introduced without consultation with SAGE was the ‘Eat Out to Help Out’ campaign which was predicted by many, and then shown, to increase the number of Covid cases (
Fetzer 2020). As became evident at the Covid-19 Inquiry, not even the CSA or CMO (Chief Medical Officer) were consulted about this policy, despite it being obvious that it would bring people together in close proximity for long periods of time in spaces with poor ventilation. The lack of consultation was not apparent to the public at the time, as the scientific advisory process was not transparent, potentially giving a signal to the public that it was now safe to spend time with people in these situations.
The UK government’s scientific advisory process for emergencies
The UK first created a ‘Scientific Advisory Group in Emergencies’ (SAGE) in 2009 in response to the H1N1 pandemic; a tenth SAGE was created in 2020 to manage Covid-19 and operated for more than two years. It was a complex organisation, comprising a large number of world-leading independent university-based scientists, government and ‘arms-length body’ scientists, and political advisors as observers. They responded speedily to government requests with a vast number of excellent, evidence-based reports. University scientists received no remuneration for their SAGE work. All were termed ‘participants’ rather than ‘members’, whether they had attended once as a guest or were central players and attended all meetings. Of the more than 100 participants, there was a core of regular attenders, some of whom were chairs of sub-committees including the modelling group (SPI-M-O) and the behavioural science group (SPI-B) in which the author participated. As an indication of the volume of evidence and advice generated, SPI-B alone produced more than 100 reports with actionable advice (
SPI-B 2020c).
SAGE was supported by a well-developed secretariat within the Government Office for Science. Advice based on evidence and scientific thinking addressing specific questions, with executive summaries, were passed to the main SAGE committee for review and ‘signing off’ before being sent to a variety of committees. The advice was reactive in that it could only be developed in response to ‘commissions’ from government. SAGE advice was communicated to government (COBRA and the Cabinet) via SAGE’s Chair, the Chief Scientific Adviser (CSA), Patrick Vallance and the Chief Medical Officer (CMO), Chris Whitty.
In the early weeks, SAGE operated in secret, without making public its membership, minutes or reports until May 2020. Considerable concern was expressed, including from former Chief Scientific Advisor David King, who responded by convening a multidisciplinary group of leading scientists and science-based practitioners to communicate scientific evidence and its implications openly and directly to the public and media: ‘Independent SAGE’.
6 The positive response to its first broadcast, hosted by an organisation called ‘Citizens’,
7 led to its continuation over the next 3
$\frac{1}{2}$ years.
In many ways, SAGE was undoubtedly successful, producing a wealth and broad range of evidence-based scientific advice in hundreds of reports published on the government website (
SAGE 2020c). The over-arching question this article addresses is whether there is room for improvement in the model of translating scientific advice to government, including methods for providing advice and its translational routes and, if so, what changes might be helpful in the future.
2. Could the science and its implications for policy and practice have been communicated better to the public?
Good pandemic management has good communication at its core, both to convey key information and to gain the trust of the population and thus increase adherence to measures to limit pandemic transmission and harm. Weaknesses in the UK’s official mechanisms for communicating science to the public during Covid-19 have been indicated in a joint report from two parliamentary committees (
Health and Social Care and Science and Technology Committees 2021). The UK government’s messages often failed to indicate what people should do or the rationale for what was being communicated: for example ‘Stay Alert; Control the Virus; Protect the NHS’ and ‘Hands, Face, Space’. Press conferences produced slides at speed, heavy with unexplained data and other information that was difficult even for numerate scientists to decipher. Independent SAGE and others called on the government to consult with academics on the vital task of communicating how to assess and manage risk. As mentioned previously, since communication had been taken out of the scope of SPI-B, there was no official body responsible for providing the scientific advice to inform communication strategies and operations.
Two important methods for communicating science to the public are via the media and via platforms in which scientists can directly engage with public audiences. A 2022 review of trust in scientific advice stressed the importance of promoting the accessibility and transparency of science to the public through, for example, panels of scientists speaking to and listening to the public, public events and the wider media (
British Academy 2024). However, the SAGE ethos and strong message coming from the CSA, as he outlined in his witness statement to the Covid-19 Inquiry, was that SAGE and its sub-group participants should be very circumspect when interacting with the media. A meeting minute presented to the inquiry reported that ‘Vallance started the meeting by highlighting he had seen several reports in media of SAGE members commenting on the science behind the government’s approach. He highlighted that this was not helpful, saying that no one should be speaking to the media’ (
Vallance 2023), although Vallance clarified this to say that they could talk about their own expertise. In an email to the Prime Minister revealed during the inquiry, Vallance stated in June 2020 ‘I think there is too much enthusiasm for the camera at the moment and will speak to them [SAGE members] again’ (
Wainwright 2023).
A group of about 14 scientists, Independent SAGE, was brought together early in the pandemic when SAGE was still operating in secret by a former CSA, David King. Its purpose was to communicate with the public about scientific knowledge and thinking relevant to Covid-19 management. In June 2020, when the government stopped its regular Covid press briefings, Independent SAGE started weekly public briefings streamed live via YouTube, to present data, address specific topics, sometimes hosting guests with expertise in particular areas, and answer questions.
8 The broadcasts continued for more than three years, regularly attracting up to 20,000 viewers (150,000 maximum); its Twitter (X) account was followed by >173,000 people.
The briefings, and communications via social and conventional media, addressed scientific and policy-relevant questions posed by the public, media and decision-makers. In order to build good understanding about the transmission and harms of Covid-19 at individual and population levels, the group included scientific leaders in, for example, public health, immunology, virology, behavioural and social sciences, genetics, evolutionary biology and mathematical modelling. The group held weekly internal meetings to bring together relevant and new research findings from disparate academic disciplines and discuss their policy and practice recommendations. These discussions informed responses to questions from the public and organisational representatives that were posed via social media and the Independent SAGE website. Questions were answered on broadcasts, by email and through regular reports posted on the website.
Vallance regarded Independent SAGE as a problem and in addressing the inquiry said that he thought it problematic to both be on a government advisory body and on a public-facing science communication body because the latter would undermine the former role: ‘it was very, very difficult when scientists spoke about policy and other areas because it then undermined trust in the committees’ (
Vallance 2023). Vallance’s views that scientists should have to choose between advising the government and communicating with the public was part of his inquiry testimony. In relation to SPI-B members joining Independent SAGE, he said ‘I’m second to none in my belief in academic freedom, but if you join a government committee it’s slightly odd to then be on a committee that’s set up to challenge the government committee’ (
Vallance 2023). It is unfortunate that he misrepresented the aims of Independent SAGE, which were definitely not to challenge SAGE (indeed, views were nearly always consistent) but to communicate science transparently and directly.
The tension between serving on a government advisory committee and publicly commenting on policy implications of that scientific advice was well expressed by the Chair of SPI-B Rubin:
It was a legitimate tension, it was a difficult issue, and I still don’t have an answer to it. Academics have academic freedom, and we fight very hard for that, and it’s part of our identity, and I think it’s very important in forming the public debate, and part of that academic freedom is the freedom to comment on public policy. At the same time, if the committee is to be trusted by government and we’re to have government departments come to us and be frank with us about the quandaries that they have or the dilemmas or the uncertainties and to give us information that they may not necessarily want to disclose in the public domain, while it is making those kind of—a running commentary on public policy, does that detract from the government’s ability to approach the group? So there is that tension there and I must admit I was never able in my own mind to resolve that tension, although I was quite clear throughout that as academics, everybody on the group did retain the right to talk to the media about whatever they wished (
Rubin 2023: 23).
An alternative point of view to that of the CSA, and one shared by Independent SAGE members and many authors writing about science communication, was expressed by Professor Alice Roberts, in the last session of Independent SAGE (December 2023):
9I think Patrick Vallance was wrong, simply wrong about engagement. As a professor of public engagement in science, it was really dismaying for me to hear that view. I don’t think at all that scientists should be retreating inside their ivory tower, slamming the doors and only talking to policymakers and not talking to the public … if you’re in a democracy, that is not even an option.
The process of placing scientific ideas and evidence into its broad context within public arenas helps to develop scientific findings into scientific knowledge suitable for public use. Most scientists, especially those in public health or in a social or behavioural science, are encouraged to speak to the public; indeed, the Science Media Centre has been set up to support and train scientists to communicate science in language understood by all.
10Providing scientific advice to official organisations is a complementary function to communicating with the media and the public. One of the recommendations of the 2000 BSE Inquiry was to consider how scientific advisory bodies can be encouraged to engage in regular dialogue and engagement with the public (
Phillips 2000). A key aim of Independent SAGE was to support leading scientists to communicate directly with the public (
Independent SAGE 2020b;
McKee et al. 2022). Indicators of its success were its high levels of engagement by MPs, city mayors, local government officers, non-governmental organisations and the wider public. Direct communication of transparent scientific advice to the public from trusted sources is key to maintaining public trust which, in turn, is key to the effective management of a crisis (
Bargain & Aminjonov 2020;
Bollyky et al. 2020;
Wright et al. 2021). Data during Covid-19 showed low and decreasing levels of trust in the UK government, and good levels of trust in scientists (
Ipsos 2022). This suggests that scientific advisors should engage proactively with the public, and not limit their communication to being alongside politicians. Former CSA David King was clear that scientific advisers should act as bridges between the scientific and political systems, but also that their role was to engage and inform the public and media directly, not just limiting their role to being part of politicians’ briefings (
King 2020). In his testimony to the Covid-19 Inquiry, Andy Burnham, Mayor of Greater Manchester, explained that, given the experience of the 2019 swine flu pandemic, he thought it would have been better to have health messages coming from experts, not politicians, and had unsuccessfully advocated this in early 2020. The advantage of having scientists alongside government officials at press briefings is that it gives official communications added weight; the disadvantage is that it may give the impression that scientists (such as the SCA and CMO) were supportive of policies that were harmful for public health and that they privately disagreed with.
If a government fails to implement evidence-based policies, scientists with both a government and public-facing role may face a quandary. On the one hand, scientists should be free to criticise policies that may be causing harm or even costing lives whilst also in a role providing advice to the government. University scientists should be independent of, not beholden to, any government. This point has been made by Farrar, SAGE member and former Director of the Wellcome Trust: ‘Does staying in an advisory role mean being complicit in the outcomes of bad decisions?’ (
Farrar & Ahuja 2021), and by myself and co-authors: ‘scientific advisers have a right and obligation to ask, if their advice does not appear to be reflected in policy, why this is the case—and, if appropriate, to explain this to the public’ (
Michie et al. 2022). On the other hand, scientists in a formal role feel a responsibility to present a united front, even when they may disagree with what is or is not being said by other scientists in a formal role. On the point about being able to both advise government and the public directly, Vallance told the inquiry,
Well, I don’t know if it was the best. I mean,
there may be better ways of doing it [my emphasis]. I did know that it was very, very difficult when scientists spoke about policy and other areas because it then undermined trust in the committees, and we saw that later in the pandemic with some departments and some ministers saying, ‘I won’t bring something to SAGE because it’s just going to leak and people will talk about it.’ (
Gething 2024).
This is conflating talking broadly about science and policy implications with leaking confidential information which no-one would support. Despite saying that there may be better ways of doing it, Vallance also makes it clear that in the SAGE Development Plan, scientists will need to choose between advising government or sitting on other science communication bodies, or at least only do the latter with permission. To arrive at the best practice in complex situations such as this, I suggest that this quandary requires extensive and open discussion and empirical research to identify the pros and cons of options and then to maximise the pros and ameliorate the cons.
The CSA and CMO have different roles from those of independent scientists serving on SAGE, as they are senior public servants and accountable to government. They therefore have to balance their duties to the public as quasi-independent scientific experts with needing to build trust within government. SAGE members on the other hand, are, or should be, truly independent and should not compromise their communication of science and its implications by feeling a need to find favour with the acting government. Of course, all scientists need to be circumspect in how they present their scientific advice, seeking to maintain trust across as wide a board as possible, but this should not, in my view, mean refraining from criticising government policy when it is counter to scientific advice and to public health and safety.
There were differing views about the breadth of expertise that scientists should feel free, and able, to draw on in communicating with policy-makers and the public about scientific matters in relation to Covid-19. There were also differing views about the extent to which scientists should feel free to discuss policy implications of relevant scientific evidence. One view was that scientists should not talk about matters other than their own specific field of study (‘stay in your lane’), nor discuss policy implications of scientific advice nor comment on government policies. In his testimony to the Inquiry, Vallance said: ‘the repeated commentary that I made at SAGE, was:
any of you can speak to your own topic, your own expertise, in the press and should feel free to do so. … We asked that people didn’t comment on policy, because that then would confound the SAGE remit with their policy views, and we asked that they tried not to stray into areas that were not their area of expertise, because that inevitably would reflect back on SAGE …’ (
Vallance 2023).
The notion of only speaking about your own work or research directly related to it has been termed ‘staying in your lane’. This goes against the increasing recognition in public health and other areas of health studies, that the subject is intrinsically multidisciplinary and that we should aim to be thinking and working in interdisciplinary ways. For example, one cannot understand the health effects of phenomena such as austerity or the collapse of the USSR without bringing together insights that stretch from biological and pathological mechanisms to social and political sciences. Similarly, one cannot understand how best to enable people to reduce viral transmission and its effects without understanding many aspects of the virus. Complex problems require teams that include specialists in particular areas and have a breadth that allows them to appreciate the contributions of other disciplines. Thus, where possible, public health should be transdisciplinary, since often knowledge cannot be assigned to any one discipline and the whole is greater than the sum of its parts (
Egede et al. 2021;
Jenkinson 2021). This interdisciplinary ‘team science’ and systems approach is advocated within public health research, policy and practice (
Academy of Medical Sciences 2021). It was also very much in evidence in both SPI-B and Independent SAGE, where reports and communications were interdisciplinary, drawing on a range of academic disciplines to produce advice that cut across disciplinary ‘lanes’. However, this was not reflected in the main translational route between SAGE and the government which was via the CSA and CMO, both medical professionals. Had there been the model adopted in Scotland of more direct contact between scientists with different disciplinary backgrounds and government, the harmful notion of ‘behavioural fatigue’ would have been unlikely to gain traction (
Michie et al. 2020). A Chief Scientific Officer for behavioural and social sciences, as suggested in a House of Lords Science and Technology Committee report, is likely to have corrected this notion (
Science and Technology Committee 2011b).
The ‘across lanes’ view might be characterised as ‘look across lanes, learn from what is in them that might be helpfully integrated with what is in your lane to enable the lane to widen, with many feeder lanes’. This requires capabilities, held by many scientists, of cross-disciplinary learning and interdisciplinary engagement and communication. This means being able to discuss issues in broad terms and drawing on a range of disciplinary expertise, whilst acknowledging the boundaries of one’s own expertise. This approach was embodied by Independent SAGE which presented ‘joined up’ information in response to new issues or public questions, informed by knowledge across many disciplines. Examples were behavioural scientists learning about viral transmission and mutation into new variants (for example, a highly cited Conversation piece on variants led by a behavioural scientist) (
Michie et al. 2021), and virologists learning about methods for supporting the public to adhere to rules. Issues interact with each other and cannot be neatly divided into separate lanes. The concept of separate lanes reflects a more biomedical, rather than public health, model of science.
The contribution of Independent SAGE (and other independent inquiries and advisory civil society and professional organisations) was recognised by the analysis of the UK scientific advisory system based on international comparisons mentioned earlier (
Jarman et al. 2022), and by a review of trust in science (
British Academy 2024). They pointed to limitations consequent on the UK government’s control over the original SAGE membership and over the issues for which scientific advice was sought. A conclusion of Donovan’s empirical study of four case studies of providing scientific advice in crises was that:
crisis situations should involve wider dialogues than simply the use of existing committees. While the UK SAGE mechanism is designed to provide flexibility, it has been less effective in the COVID-19 pandemic than in other cases. Some of the reasons for this may be political but others are institutional. Perhaps an ideal would be to incorporate additional flexibility and dialogue with the Independent SAGE and wider expert groups on risk, particularly from the social sciences and the WHO (
Donovan 2021).
3. Do scientists have a social responsibility to discuss policy implications of scientific evidence and challenge politicians when their statements or behaviour go against prevailing evidence?
The experience of Covid-19 and the different roles and perspectives that UK scientists took raises the question of the role of scientists and academics more generally in crises. Do scientists have a social responsibility to try to communicate their research to the public even if feels a bit messy and not pure? Definitely, according to Alice Roberts, Professor of public engagement in science, who summed up this position in the final session of Independent SAGE (December, 2023) (
Independent SAGE 2023):
Communication is part and parcel of good scientific practice … studies have shown time and time again that you can you can present scientific facts [but that] isn’t enough … whether or not people trust science … comes back to the scientists themselves and their willingness to engage, to listen to people, to be to be seen, to be human, to have a dialog, to empathize … Science isn’t just a body of abstract knowledge. It is people who are doing it. And you keep trust through openness and honesty and humility. … there’s a philosophical and a moral dimension to this … which is about the role of scientists in society, the fact that scientists have a moral duty even to engage with the public, not just be getting on with their science in their labs, but to be out there talking about it and to engage with the public and to make sure that that science is benefiting everyone in society.
Many working within public health maintain that public health is intrinsically political (
Bekker et al. 2018;
Mackenbach 2009) and that there cannot be a clean separation between scientists and the political process, especially in complex, contested situations (
Funtowicz & Ravetz 1993;
Jasanoff 1994;
Sarewitz 2011). This is reflected in a growing literature on politics and health, pointing to a two-way relationship. For example, political decisions, such as austerity, have a profound impact on health (
Karanikolos et al. 2013), but poor health creates fertile ground for populist politicians, with communities who felt they were abandoned, disproportionately voting for Donald Trump (
Bor 2017) and Brexit (
Koltai et al. 2020). A science writer awarded the Pulitzer prize for his coverage of the pandemic in the United States, Ed Yong, stated:
The naive desire for science to remain above politics meant that many researchers were unprepared to cope with a global crisis that was both scientific and political to its core. Science is undoubtedly political, whether scientists want it to be or not, because it is an inextricably human enterprise (
Yong 2021).
Whether or not one accepts the intersections between public health and politics, those who belong to scientific and professional bodies (for example, the British Psychological Society or the British Medical Association) agree to abide by a code of ethics. This includes not just understanding ill health but combatting it. The logic of this is that scientists should feel not only free, but duty-bound, to point out when policies and messages are potentially harmful.
Need for empirical and theoretical research
Our role as scientists ought to be to
investigate the processes [my emphasis] surrounding the use of evidence and policy activities more widely and to disseminate findings in order to help others make informed decisions, of all kinds(
Oliver et al. 2014).
There is a need both to learn retrospectively from the Covid-19 SAGE and to set up structures in advance of future crises so that scientific advisory processes can be monitored and evaluated concurrent with advice being provided. An ESRC-funded study of how SPI-B advice was translated between SAGE and government during Covid-19 is being conducted over 2024–5, based on participant interviews and documentary analysis (for protocol, see
https://osf.io/m9yt3/). It is hoped that UK’s preparation for the next pandemic includes a protocol for evaluating the scientific advisory process.
