Ideologies and nanotechnology

There are many debates about nanotechnology; what it is, what it will make possible, and what its dangers might be. On one level these may seem to be very technical in nature. So a question about whether a Drexler style assembler is technically feasible can rapidly descend into details of surface chemistry, while issues about the possible toxicity of carbon nanotubes turn on the procedures for reliable toxicological screening. But it’s at least arguable that the focus on the technical obscures the real causes of the arguments, which are actually based on clashes of ideology. We supposedly live in a non-ideological age, so what are the ideological divisions that underly debates about nanotechnology? I suggest, for a start, these four ideological positions, each of which implies a very different attitude towards nanotechnology.

  • Transhuman. Transhumanists look forward to a time in which technology allows humanity to transcend its current physical and mental limits. Radical nanotechnologies are essential to the fulfillment of this vision, so the attitude of transhumanists to nanotechnology in its most radical, Drexlerian form, is that it is not only inevitable but morally mandated.
  • Transglobal. Those who accept the current neo-liberal, globalising consensus look to new technologies as a driver for further economic growth. Nanotechnology is expected to lead to changes which may be disruptive to individual business sectors, but which probably won’t fundamentally change global socio-economic systems.
  • Deep Green. To radical environmentalists, our current urban, industrial economic system is unsustainable. Technologies are regarded as in large measure responsible for the difficulties we are now in, and a return to more rural, post-industrial, locally based economies is regarded as not only desirable but inevitable. Nanotechnology is, like most new technologies, viewed with deep distrust, as very likely to lead to undesirable and possibly unintended consequences.
  • Bright Green. Another strand of environmentalists share with Deep Greens the conviction that the current socio-economic system is unsustainable, but are confident that new technology and imaginative design will make possible an urban culture with a high standard of living that is sustainable. These people look with enthusiasm to nanotechnology for new sustainable energy systems and decentralised, low waste manufacturing processes.

When one sees a debate about nanotechnology start to get heated, it’s perhaps worth asking what the ideological positions of the debaters are, and whether an apparently technical argument is actually a proxy for an ideological one.

Everyware

This week’s Economist has a very interesting survey of the future of wireless technology, which assesses progress towards ubiquitous computing and “the internet of things” – the idea that in the near future pretty well every artefact will carry its own computing power, able to sense its environment and communicate wirelessly with other artefacts and computer systems. The introductory article and the (rather useful) list of sources and links (including the book by Adam Greenfield – Everyware: The Dawning Age of Ubiquitous Computing – whose title I’ve appropriated for my post) are freely available; for the other seven articles you need a subscription (or you could just buy a copy from the newstand).

Evolutionary nanotechnology is likely to contribute to these developments in at least two ways; by making possible a wide range of sensors able to detect, for example, very small concentrations of specific chemicals in the environment, and, through technologies like plastic electronics, by making possible the mass-production of rudimentary computing devices at tiny cost. Even with current technology, these developments are sure to raise privacy and security issues, but equally may make possible unimagined benefits in areas such as health and energy efficiency. The Economist’s survey finishes on an uncharacteristically humble note: “There is no saying how it will be used, other than it will surprise us.”

Nanotechnology: Some questions for social scientists

In 2003 I was one of the coauthors of a report – ‘The Social and Economic Challenges of Nanotechnology’ (PDF) – commissioned by the UK’s Economic and Social Research Council – this is the body which distributes government research funding to social scientists. Last year the ESRC commissioned me and my coauthors, Stephen Wood and Alison Geldart, to write a follow-up report summarising the way the debate about nanotechnology had evolved over the intervening years. The follow up report is now available from the ESRC web-site – Nanotechnology: from the science to the social (2 MB PDF) – and for those with a shorter attention span a short briefing (765 kB PDF) is also available.

One of our aims was to identify some questions that we thought were worthy of further study by social scientists. Here are some of the issues we thought were worth some more study:

The development of nanotechnology

Nanotechnology has some unique features as a case study for the social science of science, as it appears to have arisen not just as a natural development from existing disciplines, but at least partly as a result of external factors. This poses a number of interesting questions:
1) Is nanotechnology developing into a distinct field – that is, are there social and institutional pressures causing scientists in well-established disciplines such as chemistry and physics to assume a new disciplinary identity?
2) Is the nucleation of the field of nanotechnology, if this indeed is taking place, an integral part of the transformation of science from Mode 1-type to Mode 2-type and is nanotechnology being developed as a field precisely by those scientists who embrace Mode 2 values?
3) Are the grand visions associated with radical views of nanotechnology influential in shaping the development of science and technology, despite the rejection by many scientists of the assumptions on which they are based?

Nanotechnology, industry and the economy

Nanotechnology poses important questions in relation to technological innovation and its relationship to wealth creation. Governments and agencies worldwide are providing substantial financial support for nanotechnology on the basis of tacit or explicit assumptions that this support will yield substantial economic dividend. These assumptions need critical examination; some questions that arise include the following:
1) Is there, or will there ever be, a nanotechnology industry?
2) Will there be “nanotech” clusters comparable to “biotech” and information technology clusters?
3) Will these be geographical clusters, or could there be virtual clusters?
4) Will there be clusters associated with discrete sub-areas of nanotechnology, such as (for example) bionanotechnology for diagnostics?
5) As governments look to nanotechnology as a driver of innovation and economic growth, tacit or explicit models of the innovation process are being invoked to help frame policy. Are these models of innovation applicable to nanotechnology (or indeed any other new technology)?

Nanotechnology and internationalisation

Government support for Nanotechnology has included non-western countries and the EU, making it a unique and important case study in the further internationalisation of science and innovation. Questions that arise from this include:
1) What is the scope for government policy to influence innovations in the nanotechnology area, both between and within organisations, in an increasingly global economy?
2) Is there an emerging international division of labour in the development of nanotechnology?
3) Can nanotechnology make significant contributions to the development of less-developed countries? Contrasts between China and India, which are receiving most attention, with countries where nanotechnology has been given a significant role in plans but are receiving less attention, like Brazil, may be instructive.
4) Is there any truth in the caricature of the ‘Wild East’, i.e. a place without ethical or intellectual property-bound constraints unfairly competing with western countries?
5) As nanotechnology may be the first science in modern times in which substantial and original developments take place in non-western cultures, can it offer any insights about cultural relativism in science?

Technology development and society

The portrayal of nanotechnology in popular culture is strongly influenced by social movements outside the scientific mainstream. The significance of this unusual feature should be examined:
1) Some futurists argue that nanotechnology itself is accelerating the rate of technological change and hence social change – does this stand up to scrutiny?
2) How does nanotechnology fit into broader social movements about technology development, and do such movements depend on grand visions (positive or negative)?
3) Is there any significance to those movements, such as transhumanism, which are associated with the promotion of more futuristic visions of nanotechnology? What role do these movements have in shaping broader societal debates, such as the nascent debate about human enhancement?

Public engagement

The widespread consensus about the desirability of public engagement in connection with nanotechnology should receive some critical scrutiny:
1) The public engagement activities and the methods used could be evaluated, including a cross-country comparison of the various experiments in it and the role of the dissemination of scientific knowledge within this process.
2) While accepting the force of the critique of the deficit model of public understanding, one needs to understand the origins of the public’s understanding of nanotechnology, and particularly the relative influence of the various interest groups, whose visions of nanotechnology may be very different, as well as popular media, serious journalism, science fiction, and computer games.

An uncertain business

Last November, the Royal Society hosted an event at which companies were asked the question “How can business respond to the technical, social and commercial uncertainties of nanotechnology?” I was one of only a couple of academics at the event, which attracted representatives of 17 companies, many of them very large household names not previously associated with nanotechnology. The event took place somewhat under the radar, and was conducted under Chatham House rules, allowing the participants to speak freely without what they said being attributed to them. However, some information about the day has now been released in the form of this short workshop report (PDF).

The joint sponsors of the day were Royal Society, the Nanotechnology Industries Association, and Insight Investment. The Royal Society’s interest is obvious, in view of its long-standing involvement in considering the broader implications of nanotechnology, and it’s no surprise that the NIA, a newly established trade association, would want to be involved. The participation of Insight Investment is perhaps more surprising and interesting; this is a fund manager with around £100 billion in investments. This means that they hold, on behalf of clients including large institutions and pension funds, substantial equity stakes in many of the companies that took part. Thus they have a direct financial interest in whether the companies in question are in a position to exploit business opportunities that arise from the uses of nanotechnology, and can deal sensibly with any uncertainties that might arise.

The position paper that was written to inform the discussion – An uncertain business (PDF) – is now also available. This divides the uncertainties that might be associated with nanotechnology into three categories. Technical uncertainties include the well-known issues about possible toxicity of nanoscale materials, while social uncertainties involve the different ways in which people might react to new products involving nanotechnology. But many of the participants were exercised by possible commercial uncertainties, that is to say issues such as the potential risks to brand value that bad publicity might lead to, together with risks to cost of capital and insurance that might arise from adverse opinion in the financial and insurance markets.

Where should I go to study nanotechnology?

The following is a message from my sponsor… or at least, the institution that pays my salary…

What advice should one give to young people who wish to make a career in nanotechnology? It’s a very technical subject, so you won’t generally get very far without a good degree level grounding in the basic, underlying science and technology. There are some places where one can study for a first degree in nanotechnology, but in my opinion it’s better to obtain a good first degree in one of the basic disciplines – whether a pure science, like physics or chemistry, or an engineering specialism, like electronic engineering or materials science. Then one can broaden one’s education at the postgraduate level, to get the essential interdisciplinary skills that are vital to make progress in nanotechnology. Finally, of course, one usually needs the hands-on experience of research that most people obtain through the apprenticeship of a PhD.

In the UK, the first comprehensive, Masters-level course in Nanoscale Science and Technology was developed jointly by the Universities of Leeds and Sheffield (I was one of the founders of the course). As the subject has developed and the course has flourished, it has been expanded to offer a range of different options – the Nanotechnology Education Portfolio – nanofolio. Currently, we offer MSc courses in Nanoscale Science and Technology (the original, covering the whole gamut of nanotechnology from the soft to the hard), Nanoelectronics and nanomechanics, Nanomaterials for nanoengineering and Bionanotechnology.

The course website also has a general section of resources that we hope will be useful to anybody interested in nanotechnology, beginning with the all-important question “What is nanotechnology?” Many more resources, including images and videos, will be added to the site over the coming months.

At the Edinburgh International Science Festival

Anyone who was at a loose end in Edinburgh tomorrow evening could come and hear me give a talk called Nanotechnology – Soft Machines, as part of the Edinburgh International Science Festival.

I would also have liked to have said that anyone turning up would have had the opportunity to buy a signed copy of my book, Soft Machines: nanotechnology and life, but I got a somewhat sheepish email from my publisher confessing that they had run out of stock. Still, it’s not all bad news, in that the paperback version of the book will be out in October.

Meanwhile, in my dungeon laboratory…

The Council for Science and Technology report, which criticised the UK government’s record in getting research going on the health and environmental effects of nanoparticles, has led to quite a lot of media coverage, of various degrees of inaccuracy. My favourite is this story in The Register: UK government slated by own boffins on nanotech policy. Taking its cue from the Science Minister’s line – which seemed to be, in effect, we gave the scientists lots of money but they chose to spend it doing exciting new science rather than getting the toxicology right, The Register’s Lewis Page sagely commented:

“This has been true ever since the first mad professor set up his dungeon laboratory, of course. Any scientist worth his salt would rather work out how to make dead flesh live again than write up the safety case for doing it. Even so, it’s nice to see boffins finally admitting this.”

This is irresponsible and gratuitously stereotyping journalism, of course, but I thought it was funny.

A critical verdict on the UK’s nanotoxicology record

As I trailed a couple of days ago, the Council for Science and Technology yesterday published their report assessing the UK government’s progress in meeting the commitments it made in response to the 2004 Royal Society report on Nanotechnology. The report, Nanoscience and Nanotechnologies: A Review of Government’s Progress on its Policy Commitments (PDF, 327kB), is, as widely expected, rather critical of the Government’s response, particularly on the issue of funding research and providing an evidence base in the area of nanoparticle toxicology. This BBC online piece picks up most of the major themes.

The thrust of the report is unequivocal – the government promised an extensive program of research into the toxicology and health and environmental effects of nanomaterials, and this research has not happened. The reason for this is equally clear – money wasn’t set aside to fund it. Instead, it was decided to rely on scientists coming forward with funding proposals to be judged, in competition with proposals in other areas of science, by peer review. That this approach would prove to be completely inadequate was widely predicted at the time, and those predictions turned out to be entirely correct. As I wrote myself a year ago here: ‘This seems to me to be a category error – the science we need to underpin regulation isn’t necessarily good science as defined by peer review, and if the capacity to do the research isn’t there one can’t just expect it to appear spontaneously.”

The Science Minister, Malcolm Wicks, was questioned about the report on this morning’s BBC Radio 4 Today program. In his interview – downloadable here as an MP3 file (the interview is the last item) – he accepts the basic thrust of the criticism, but blames the reseach councils (in particular the Medical Research Council) for not being proactive, and scientists for not coming forward with the proposals. This, of course, is precisely the point. To be fair to him, he’s taking the flak for decisions made by his predecessor. A full, formal government response to the CST report will presumably follow.

Judgement day for UK nanotechnology policy

There’s a certain amount of anxious anticipation in UK nanotechnology policy circles, as tomorrow sees the publication of the results of a high-level, independent review of the government’s response to the 2004 Royal Society report on nanotechnology – Nanoscience and nanotechnologies: opportunities and uncertainties.

The report was prepared by the Council for Science and Technology, the government’s highest level science advisory committee, which reports directly to the Prime Minister. I wrote earlier about the CST seminar held last autumn to gather evidence, and about the Royal Society’s suprisingly forthright submission to the inquiry. We shall see tomorrow how much of that criticism was taken on board by the CST, and how the Science Minister, Malcolm Wicks, responds to it.

Science Horizons

One of the problems of events which aim to gauge the views of the public about emerging issues like nanotechnology is that it isn’t always easy to provide information in the right format, or to account for the fact that lots of publicly available information may be contested and controversial in ways that are difficult to appreciate unless one is deeply immersed in the subject. It’s also very difficult for anybody – lay person or expert – to be able to judge what impact any particular development in science or technology might actually have on everyday life. Science Horizons is a public engagement project that’s trying to deal with this problem. The project is funded by the UK government; its aim is to start a public discussion about the possible impacts of future technological changes by providing a series of stories about possible futures which do focus on everyday dilemmas that people may face.

The stories, which are available in interactive form on the Science Horizons website, focus on issues like human enhancement, privacy in a world with universal surveillance, and problems of energy supply. These, of course, will be very familiar to most readers of this blog. The scenarios are very simple, but they draw on the large amount of work that’s been done for the UK government recently by its new Horizon Scanning Centre, which reports to the Government’s Chief Scientist, Sir David King. This centre published its first outputs earlier this year; the Sigma Scan concentrating on broader social, economic, environmental and political trends, and a Delta Scan concentrating on likely developments in science and technology.

The idea is that the results of the public engagement work based on the Science Horizons material will inform the work of the Horizon Scanning centre as it advises government about the policy implications of these developments.
