Time to reclaim the values of science

This post is dedicated to Paul Picard, my grand dad, who was the oldest reader of my blog. He was 17 (and Jewish) in 1939 so he did not get the chance to go to University. He passed away on the first of October 2016. More on his life here (in French) and some of his paintings (and several that he inspired to his grandchildren and great-grandchildren). The header of my blog is from a painting he did for me

A few recent events of vastly different importance eventually triggered this post.

A  (non-scientist) friend asked my expert opinion about a campaign by a French environmental NGO seeking to  raise money to challenge the use of nanoparticles such as E171 in foods. E171 receives episodic alarmist coverage, some of which were debunked by Andrew Maynard in 2014. The present campaign key dramatic science quote “avec le dioxyde de titane, on se retrouve dans la même situation qu’avec l’amiante il y a 40 ans {with titanium dioxide, we are in the same situation than we were with asbestos 40 years ago}” is from Professor Jürg Tschopp. It comes from an old media interview (2011, RTS) that followed a publication in PNAS. We cannot ask Professor Tschopp what he thinks of the use of this 5 years old quote: unfortunately he died shortly after the PNAS publication. The interpretation of this article has been questioned since: it seems likely that the observed toxicity was due to endotoxin contamination rather than the nanomaterials themselves. There is on the topic of nanoparticles a high level of misinformation and fear that finds its origins (in part) in how the scientific enterprise is run today. Incentives are to publish dramatic results in high impact factor journals which lead many scientists to vastly exaggerate both the risks and the potential of their nanomaterials of choice. The result is that we build myths instead of solid reproducible foundations, we spread disproportionate fears and hopes instead of sharing questions and knowledge. When it comes to E171 additives in foods, the consequences of basing decisions on flawed evidence are limited. After all, even if the campaign is successful, it will only result in M&M’s not being quite as shiny.

I have been worried for some time that the crisis of the scientific enterprise illustrated by this anecdote may affect the confidence of the public in science. In a way, it should; the problems are real, lead to a waste of public money, and, they slow down progress. In another way, technological (including healthcare) progress based on scientific findings has been phenomenal and there are so many critical issues where expertise and evidence are needed to face pressing humanities’ problems that such a loss of confidence would have grave detrimental effects. Last week, in the Spectator, Donna Laframboise published an article entitled “How many scientific papers just aren’t true? Enough that basing government policy on ‘peer-reviewed studies’ isn’t all it’s cracked up to be“. The article starts by a rather typical and justified critique of peer review, citing (peer-reviewed) evidence, and then, moves swiftly to climate change seeking to undermine the enormous solid body of work on man-made climate change. It just happens that Donna Laframboise is working for “a think-tank that has become the UK’s most prominent source of climate-change denial“.

One of the Brexit leaders famously declared that “people in this country have had enough of experts”. A conservative MP declared on Twitter that he”Personally, never thought of academics as ‘experts’. No experience of the real world. Yesterday, Donald Trump, a climate change denier was elected president of the USA: “The stakes for the United States, and the world, are enormous” (Michael Greshko writing for the National Geographic). These are attacks not just on experts, but on knowledge itself, and, the attacks extends to other values dear to science and encapsulated in the “Principle of the Universality of Science“:

Implementation of the Principle of the Universality of Science is fundamental to scientific progress. This Principle embodies freedom of movement, association, expression and communication for scientists, as well as equitable access to data, information and research materials. These freedoms are highly valued by the scientific community and generally well accepted by governments and policy makers. Hence, scientists are normally able to travel to international meetings, associate with colleagues and freely express their opinions regardless of factors such as ethnic origin, religion, citizenship, language, political stance, gender, sex or age. However, this is not always the case and so it is important to have mechanisms in place at the local, national and international levels to monitor compliance with this principle and intervene when breaches occur. The International Council for Science (ICSU) and its global network of Members provide one such mechanism to which individual scientists can turn for assistance. The Principle of the Universality of Science focuses on scientific rights and freedoms but implicit in these are a number of responsibilities. Individual scientists have a responsibility to conduct their work with honesty, integrity, openness and respect, and a collective responsibility to maximize the benefit and minimize the misuse of science for society as a whole. Balancing freedoms and responsibilities is not always a straightforward process. For example, openness and sharing of data and materials may be in conflict with a scientist’s desire to maintain a competitive edge or an employer’s requirements for protecting intellectual property. In some situations, for example during wars, or in specific areas of research, such as development of global surveillance technologies, the appropriate balance between freedoms and responsibilities can be extremely difficult to define and maintain. The benefits of science for human well-being and development are widely accepted. The increased average human lifespan in most parts of the world over the past century can be attributed, more or less directly, to scientific progress. At the same time, it has to be acknowledged that technologies arising from science can inadvertently have adverse effects on people and the environment. Moreover, the deliberate misuse of science can potentially have catastrophic effects. There is an increasing recognition by the scientific community that it needs to more fully engage societal stakeholders in explaining, developing and implementing research agendas. A central aspect of ensuring the freedoms of scientists and the longer term future of science is not only conducting science responsibly but being able to publicly demonstrate that science is being conducted responsibly. Individual scientists, their associated institutions, employers, funders and representative bodies, such as ICSU, have a shared role in both protecting the freedoms and propagating the responsibilities of scientists. This is a role that needs to be explicitly acknowledged and embraced. It is likely to be an increasingly demanding role in the future.

It is urgent that we, scientists, reclaim these values of humanity, integrity and openness and make them central (and visibly so) in our Universities. To ensure this transformation occurs, we must act individually and as groups so that scientists are evaluated on their application of these principles. The absurd publication system where we (the taxpayer) pay millions of £$€ to commercial publishers to share hide results that we (scientists) have acquired, evaluated and edited must end. There are some very encouraging and inspiring open science moves coming from the EU which aim explicitely at making “research more open, global, collaborative, creative and closer to society“. We must embrace and amplify these moves in our Universities. And, as many, e.g. @sazzels19 and @Stephen_curry have said, now more than ever, we need to do public engagement work, not with an advertising aim, but with a truly humanist agenda of encouraging curiosity, critical thinking, debates around technological progress and the wonders of the world.
