The offices that give science advice to politicians are among the most important public bodies you’ve never heard of. Some nations — notably the United States and Denmark — have closed or stopped funding them. Elsewhere, these bodies are thriving: in the United Kingdom and France, for example. Differences between the healthy and the defunct hold lessons for countries that hope to improve the use of science in law-making and political debate.

Spain’s national parliament, for instance, plans to open a science and technology advisory unit this summer. In the United States, hopes have been raised this past year of the return of something like the much-missed Office of Technology Assessment (OTA), shuttered in the mid-1990s. This spring, Congress is likely to consider funding for science and technology advice in its budget appropriations for the legislative branch.

Here we offer a three-step survival guide for legislative science and technology advisory bodies (LSTABs). Our recommendations are based on the key functions and factors that seem to have led to the long-term success or failure of such bodies.

In-house expertise

Roughly 90% of legislatures lack the kind of scientific and technical advisory system that they need to be effective. Sadly, some legislatures that had such a system have lost it: the United States (in 1995), Italy (in 2009) and Denmark (in 2011).

Most northern European democracies have LSTABs. These have been around since the 1980s, inspired by the defunct OTA. One of us (C.T.) is the former director of the United Kingdom’s version, the Parliamentary Office of Science and Technology (POST). France has the Parliamentary Office for the Evaluation of Scientific and Technological Options (OPECST). The Netherlands, Norway, Germany, Austria, Switzerland and others also have similar systems.

These bodies offer legislators independent, politically impartial, expert scientific and technical advice on myriad topics. Legislating is tough: values, economics, law, social norms and politics frequently collide, leaving only difficult choices. Democracy does not work properly if politicians struggle to get their facts straight. That is where LSTABs come in.

They tend to operate behind the scenes with little fanfare, and are small compared with their executive counterparts — often having one-tenth or one-hundredth of the staff. And they aim obsessively for political and scientific impartiality. They work proactively on a dizzying array of subjects. At any one time, there are dozens of ongoing inquiries that might take weeks or months to complete. Current topics across various LSTABs include delivery drones (Austria), the digital society (the Netherlands), human genome editing (Germany), battery-charging infrastructure for electric vehicles (France) and robotics (United Kingdom).

Most legislatures also have some kind of on-demand research service that responds to legislators’ immediate requests for information. Examples include the US Congressional Research Service and the two UK Parliament ‘library’ research services in the House of Commons and the House of Lords. Often these are swamped with work, answering questions and providing background briefings in real time. The kind of in-depth, long-range advice offered by LSTABs is beyond the capacity of many of these services.

LSTABs tell politicians the things they need to know but didn’t think to ask. The most important skills of staff are distillation and impartiality — scientific and technical information is often hard to understand, and its political context can be extremely complicated. They summarize complex information into easy-to-understand nuggets, and put them in the context of a wide range of policy options that are relevant to the work of every politician, no matter to which party they belong.

But LSTABs can be politically vulnerable. The factors that led to the demise of the US OTA have been well documented (see, for example, refs 1–3). Perceived politicization, a lack of cross-party support and budget cuts took their toll. Italy’s advisory body was dissolved when its chairman, Sandro De Franciscis, left parliament. Denmark’s LSTAB had its funding removed in an apparent budgetary oversight.

This is why it is worth analysing success stories.

Success stories

That brings us to the LSTABs of the United Kingdom and France. Like the OTA (and Spain’s planned advisory unit), both bodies are part of the internal parliamentary bureaucracy. Unlike the OTA, they are thriving. The United Kingdom’s POST, established in 1989, comprises about a dozen advisers. It does a wide range of work, from organizing seminars for parliamentarians to writing ‘POSTnotes’ — summaries on topics as diverse as quantum computing and inequality.

France’s OPECST is different. Established in 1983, it is a committee of politicians tasked with helping parliament to make “enlightened decisions” by advising it on the consequences of choosing various scientific and technological options. The committee has the same standing as other parliamentary committees. So, in addition to producing technology assessments and reports, it scrutinizes the executive body and makes legislative recommendations.

These LSTABs have weathered times of trial. For example, there was an attempt in 2012 to cut POST’s funding. The fact that this didn’t work illustrates the robustness of the institution.

It is clear that certain factors have led to long-term stability for POST and OPECST. Which of these might be carried across to a resurrected OTA in the United States, or a Spanish equivalent? We have three recommendations.

Make bipartisanship real. Political oversight of the OTA was intended to be bipartisan. It was governed by a board of politicians from both parties and both houses. Yet it was perceived as partisan from the outset, largely because of the role of Senator Edward Kennedy (Democrat) in its establishment. He was twice its chairman, and had a consistent influence4. Making bipartisanship real in both practice and perception is a key feature of both the French and UK offices.

The French have designed a process that gives their bipartisanship teeth. Each OPECST study is overseen and communicated back to parliament by two rapporteurs, who are a representative mix of the following: each political wing (majority and opposition parties), each chamber (a senator and a deputy) and each gender; OPECST calls it ‘triple parity’ matching. These rapporteurs have constitutional powers, for example, to investigate any state agency, and their findings are designed to be used in legislative work and budget discussions.

This approach ensures that proposals OPECST makes have cross-party support from the start. For example, an OPECST report on bioethics in October 2018 was overseen by Jean-François Eliaou from the centrist party La République En Marche! in the lower chamber, and by Annie Delmont-Koropoulis from the centre-right Les Républicains in the upper chamber. Despite existing in such a highly political environment, this structure makes it much easier to maintain political support for the office itself.

In the United Kingdom, bipartisanship is encouraged through the composition of the POST Board. It features politicians from all the main parties and representatives from both chambers, and there are parliamentary civil servants and scientists from national research academies. The UK Parliament as a whole has a tradition of ‘leaving party politics at the committee-room door’. This is starkly true in POST’s case, in part because the bureaucrats and academics keep the politicians’ instincts in check.

Controversy or policy: pick one. All LSTABs face a dilemma. Politicians generally prefer direct answers to their questions. In other words, they want policy recommendations. They have been known to ask for ‘one-handed scientists’, so that they don’t have to hear ‘on the other hand’. Although science advisers can give policy recommendations, the more political the question, the more risk there is in answering it — and the more politicians one might enrage. So most LSTABs engage in controversial topics or make policy recommendations; they can’t do both.

POST takes the first approach — controversy, not policy. Its reports tackle highly controversial topics, such as migrants and housing, fake news, policing domestic abuse and sex education. They present evidence by making it as relevant to policy as possible, but stop short of anything that could be interpreted as a recommendation. That way, the office keeps its reputation for impartiality.

France’s OPECST takes the second approach — policy, not controversy. Because it is a politician-led office and feeds into legislative work and budget discussions at a political level, it makes policy recommendations. OPECST protects itself from extreme political backlash by sticking to scientific and technical issues. It tends to focus on technology assessment in its purest form, weighing up policy options on the basis of emerging research. Recent examples include blockchain technology and animal experimentation. It leaves issues that are more driven by social science to others. In this way, it runs up against political objections to its work less often.

Offer value for money. When the OTA closed in 1995, it had 143 staff and a budget of US$22 million. The UK and French offices are several times smaller than that in terms of people and budget, even accounting for the differences in the sizes of the countries. POST doubles its number of staff by hosting more than 30 PhD students a year on 3-month secondments. They are funded by external scientific partners, such as the funding organization UK Research and Innovation. Most of the POST fellows research and draft briefing notes; some support parliamentary committees or other research services.

These fellowships secure POST’s position with three key stakeholders: bureaucrats (who value fellows’ low-cost work); politicians (who value the links to their constituencies); and academics (who value the meaningful connections the fellows provide to Parliament).

Effecting change is also a sign of being good value. Both POST and OPECST can boast many examples of this, from the low-key (such as POST’s work to train parliamentary staff to use evidence more effectively) to the high-profile (such as OPECST’s initiative to establish a public body to oversee nuclear waste).

Next steps

There remains much work to be done to ensure that legislatures worldwide have access to the scientific and technological information they need to make crucial decisions. How should US Representatives support their local economies going into the fourth industrial revolution? How should Spanish senators tackle unemployment now and in the future? What do Brazilian deputies need to do to protect both resources and people in the Amazon Basin? How should Bangladeshi members of parliament plan for sea-level rise?

A starting point is to understand how these different parliaments source and use knowledge in their deliberations — what works and what does not (see ‘Gaps in science advice’). Among the most important questions in need of study are how to craft meaningful bipartisanship, how to balance controversial topics and direct policy impact, and how to offer value to multiple stakeholders.

Gaps in science advice

From September to November last year, we asked academics, science advisers and policymakers to identify the most pressing research questions that, if answered, could broaden our theoretical and empirical understanding of the provision of science advice for legislatures. Our study was funded by the US National Science Foundation.

The 183 respondents were from 53 countries and came up with 254 questions. These included how existing science advisory systems work, and how to design systems for information creation, communication and use in the many countries that don’t have them.

According to these experts, fundamental information about legislative science advice remains unknown (see also refs 5, 6). Gaps include what types of scientific information are used in legislatures; how different institutional approaches to legislative science advice influence its nature, quality and relevance; and how the requirements and needs of a science advice system differ across countries.

The field needs broader partnerships between academics and practitioners to plug these knowledge gaps.

If new and existing LSTABs make the right decisions for their unique political systems, their work will resonate beyond science and technology advice, and strengthen democratic foundations.
