Our research colleagues at  STEPS Centre<\/a> (UK) published this article a few days ago, which reflects on the role of science in these urgent instances. At its core lies the idea of “post-normal science”: “In post-normal conditions, the knowledge base must be pluralized and diversified to include the widest possible range of relevant knowledge and sources of potentially usable high quality wisdom, without imposing the demand for science to speak with one voice”. We find here a concept that describes Bioleft, as we work from action research, incorporating voices, methodologies and knowledge from diverse people. From the very design of the Bioleft tools to the processes of participatory seed breeding, we are committed to the collective construction of knowledge. Here the complete article.<\/h4>\n

On 19 May 1986, The Guardian<\/i> published an essay entitled \u201cDisasters bring the technological wizards to heel: Chernobyl, Challenger, and the Ch-Ch Syndrome\u201d<\/a>. At that time the authors, including two of the co-authors of this article, wrote that it was \u201cno longer feasible for ruling elites to employ experts for persuading the public that their policies are beneficial, correct, inevitable, and safe. The Ch\/Ch Syndrome amounts to a mortal blow at the scientistic foundation for the legitimacy of the modern mega-technological State. A new social contract of expertise is now taking shape.\u201d<\/i><\/p>\n

Not long after this, in 1993, Silvio Funtowicz and Jerry Ravetz published a landmark paper<\/a> on what came to be called Post-Normal Science<\/i> (PNS), a new understanding of science for situations \u201cwhen facts are uncertain, stakes high, values in dispute and decisions urgent\u201d.  The perspective of PNS \u2013 neither value-free nor ethically neutral<\/a>, is epistemological as well as practical and methodological.<\/a><\/p>\n

But after BSE, foot-and-mouth disease, SARS, H1N1, and a string of other, similar disasters that would have seemed to be exactly the sorts of situations PNS was designed to address, after energetic debates at scholarly conferences and reputable journals \u2013 where is that mortal blow? Amid a COVID-19 pandemic, where is that new social contract?<\/p>\n

The mortal blow seems to have been followed by a slow, agonizing death. Despite the truly historic mobilization of science, our knowledge in crucial areas is still swamped by ignorance, especially on the sources of the virus but also on its progress and future outcomes. The expertise employed in COVID-19 policy advice builds on speculative assumptions on the virus itself, and how far it\u2019s possible to control and predict how people behave.<\/p>\n

Known unknowns include the real prevalence of the virus in the population; the role of asymptomatic cases in the rapid spread of the virus; the degree to which humans develop immunity; the dominant exposure pathways; the disease\u2019s seasonal behaviour; the time to deliver global availability of an effective vaccine or cure; and the nonlinear response of individuals and collectives to the social distancing interventions in the complex system of communities interconnected across multiple scales, with many tipping points, and hysteresis loops (implying that society may not be able to rebound to the state it was in before the coronavirus interventions took place). These deep uncertainties make quantitative predictions speculative and unreliable.<\/p>\n

\u2018There is no number-answer\u2019<\/b><\/h2>\n

Instead, following a pattern well known to PNS practitioners, predictions which purportedly \u201cjarred the U.S. and the U.K. to action<\/a>\u201d can only be obtained by mathematical models that produce crisp numbers, even though these numbers have been obtained at the cost of artificially compressing<\/a> the associated uncertainty. \u201cThere is no number-answer to your question<\/a>,\u201d explodes an angry medical expert to the politician trying to force a number out of him.<\/p>\n

And yet the example of Taiwan<\/a> shows that the post-normal model of deployment of science in society, one where trust, participation and transparency are carefully nurtured, can indeed deliver upon its promises.<\/p>\n

The possibility of local economic collapse, along with mass panic and social breakdown, is quite real. At the same time, we seem to be unable to imagine societies that will be capable to guarantee an absolute prediction and control over what type of perturbations we may experience in the future.  It would be much more effective to run our societies under the assumption that our resources should not be allocated according to a strategy of prediction and control.<\/p>\n

Everywhere, we are seeing a total breakdown<\/a> of the epistemic consensus required to make normal science \u2018work\u2019. This is happening not only in the fields you might expect \u2013 behavioural psychology, sociology, and ethics \u2013 but also in virology, genetics, and epidemiology. In other words, when \u2018applied scientists\u2019 and \u2018professional consultants\u2019 are no longer in their comfort zones but find themselves in a post-normal context, fitness for purpose changes meaning. And even in established fields, disagreements can\u2019t be hidden (or consensus enforced) from broad audiences: are the present draconian measures justified<\/a> or not<\/a>?<\/p>\n

More data (even \u2018reliable data\u2019) and better predictive models cannot resolve the \u2018distribution of sacrifice\u2019 which involves, among other things, the arbitration of dilemmas that appear at every scale. Hiding behind some general notion of science or the \u2018lack of data\u2019 \u2013 as if data had the power to resolve these dilemmas \u2013 is feckless, feeble and confused.<\/p>\n

How do different perspectives help?<\/b><\/h2>\n

Normal Science has demonstrated great power in identifying viral structures, attachment sites, and pathogenic mechanisms. All these are essential for medical diagnostic and treatment regimes. However, to answer questions related to managing<\/i> these technologies, including setting priorities when, for instance, respirators and hospital beds reach their limit, and for identifying how to reorganize institutional structures, Normal Science offers no guidance at all.<\/p>\n

The design of the campaign, with the balancing of imponderable costs and benefits, will involve a variety of legitimate perspectives and valuations; political leadership is required for choosing among the resultant policies. The ripple effects through the levels of policy and consciousness, may well become much more severe than the initial dangers. How will existing social tensions, as between elites and anti-elites, be refracted through this crisis?<\/p>\n

The new, still-emerging social contract calls on us to pause in our vocal desperation to make square peg of normal science fit the round hole for which it was never intended, and to re-shape our activities to fit the new reality. But what if we experience, this time, more so than previously, that we are not in control? Are we condemned to do \u201cmore of the same\u201d forever until we\u2019re forced to do something else by the events (because of a collapse)? To answer this riddle, PNS suggests considering a new objectivity, one obtained (we daresay constructed) by listening to different stories and viewpoints.<\/p>\n

The PNS diagnosis asks for more, not less, deliberative democracy. It asks for mobilizing and engaging everyone affected into an \u2018extended peer community<\/a>\u2019,  fostering individual and collective agency for social learning, instead of technocratic optimization of disempowered people into the virtual reality of assumption-laden model projections under deep ignorance and based on a very limited set of institutionally-privileged forms of expertise.<\/p>\n

Under post-normal conditions, the knowledge base should be pluralized and diversified to include the widest possible range of high-quality potentially usable knowledges and sources of relevant wisdom, without enforcing the demand for science to speak with one voice. \u201cRobustness is sought here primarily in policy strategy and not in the knowledge base: which policies are useful regardless of which of the diverging scientific interpretations of the knowledge is correct.<\/a>\u201d An illustration of this approach in the context of the present discussion came when the Council of Europe usefully contested the evidence and the policy of the World Health Organization in relation to the H1N1 influenza, and \u2013 according to some researchers<\/a> \u2013 did so using a post-normal-informed analysis. WHO polices were later considered ill-advised, and possibly biased, by industrial stakeholders.<\/p>\n

What does a post-normal approach look like?<\/b><\/h2>\n

The inevitability of accidents and epidemics is \u2018uncomfortable knowledge\u2019. Confronting it is a moral act as much as a policy decision. Through PNS, we imagine strategies based on a wise monitoring and anticipation obtained by a combination of non-equivalent perceptions of our interaction with nature.<\/p>\n

This cannot be delivered by artificial intelligence, algorithms and models alone, nor can the dystopian aspects<\/a> of these latter be redeemed by the results of the Chinese response to COVID-19. We need to pursue an adaptability based on preserving diversity and flexible management.<\/p>\n

Until now, science has been used to improve the quality of life for some social groups, give people an edge on their competitors (for some social groups and countries) and to replace religion as the source of legitimization of power (ditto). It has now become apparent that specific social groups that have enjoyed the ride so far are now fighting with every political and economic weapon possible to regain control and direct the narrative.<\/p>\n

This pandemic offers society an occasion to open a fresh discussion on whether we now need to learn how to do science in a different way. Conscientious scientists and engaged citizens cannot allow this opportunity to pass.<\/p>\n

In PNS, the whole world becomes an extended peer community, as the appropriate behaviour and attitudes of individuals and masses become crucial for a successful response to the virus. This extended peer community is the opposite of a technocratic, number and model-based decision strategy. It\u2019s a community where all those with an interest have a say, from the experts of various scientific disciplines, to stakeholders, whistle-blowers, investigative journalists, and the community at large.<\/p>\n
