Effective science communication can empower research and innovation systems to address global challenges and put public interests at the heart of how knowledge is produced, shared, and applied. For science communication to play this mediating role effectively, we propose a more integrated and “evidence-based” approach. This commentary identifies key issues facing the science communication field. It suggests a series of prescriptions, inspired by the impact of “evidence-based medicine” over the past decades. In practice, evidence-based science communication should combine professional expertise and skills with the best available evidence from systematic research. Steps required to achieve this outcome include more quality assurance in science communication research, significant changes in teaching and training, and improved interfaces between science communication research and practice.

At its best, science communication can empower research and innovation systems to address global challenges, by improving the relationships with stakeholders in policy, industry, and civil society (see “Quadruple Helix,” e.g., Carayannis and Campbell, 2009, e.g., 2018ff). Science communication can put public interests at the heart of how knowledge is produced, shared, and applied today, thereby enhancing the benefits of science and technology and mitigating their limitations or risks. Moreover, effective science communication can facilitate the role of research and innovation in developing a more sustainable world. Therefore, it is imperative that science communication plays its mediating role effectively. This view of science communication's value inspires our call in this essay to open a dialogue about integrating science communication research and practice within a new vision for “evidence-based science communication.”

It has now been decades since the notion of “evidence-based medicine” gained a foothold in scholarly discourse. In this commentary, we argue that the field of science communication faces challenges that would benefit from some of the prescriptions that evidence-based medicine offers, in particular, with the aim of helping research and practice take each other's experiences and insights fully into account. This evolution is essential to drive real progress in science communication as a field of practice.

Key Challenges

Science communication today is expected to go far beyond making scientific knowledge more accessible to lay audiences. For example, ambitious notions about science communications potential role can be identified in the European policy prescription of “Responsible Research and Innovation” (RRI) or efforts to include stakeholders earlier in technology assessment and regulatory processes to establish a more “social” innovation (Phills et al., 2008, e.g., p. 39ff). With the growing expectations of 21st science communication, it also becomes increasingly important for this field to be more self-reflective and demonstrably effective. This commentary presents our view of these challenges across both science communication research and practice based on our experience in this field.

Key challenges underpinning this commentary are identified in the first empirical gap analysis for the field of science communication research (Gerber et al., 2020, p. 61ff), in particular the following: (i) to build a research corpus with effective transfer mechanisms, so that science communication practitioners can apply research in their work practice, and perhaps even investigate in collaboration with scholars the applicability of potentially useful strategies; (ii) to widen the spectrums of science communication research topics and methods, in particular by extending the existing methodological toolkit in science communication to include more longitudinal and experimental research. Experts contributing to a Delphi study in this science communication research field analysis emphasized that neither scholarship nor practice adequately take account of the other side's priorities, needs and possible solutions: This can be understood as a double-disconnect between research and practice (Gerber et al., 2020, e.g., p. 4).

Both authors of this essay have worked in science communication practice and research, and especially at the interface between the two domains over many years in this evolving field. In this time, we have seen many challenges that trouble the research/practice interface in science communication (e.g., see Fischhoff, 2013, e.g., p. 14038). Many of these challenges have been raised in one form or another in empirical studies of science communication research and practice (e.g., Holliman and Jensen, 2009; Gerber, 2014; Jamieson et al., 2017; Gerber et al., 2020). Ironically, the challenges begin with communication about science communication evidence (see Table 1). The framework suggested here, based on our experience, addresses four usually sequential steps of a “Knowledge Cascade,” which is addressed on four levels, namely Relevance, Accessibility, Transferability, and Quality assurance.

It is both self-evident and revealing that there is limited empirical evidence that speaks to the generalizations and truth claims presented in the table above based on our practical experience across the research-practice divide in science communication. We think the sparse research available on these topics highlights the need for more evidence-based integration and mutual learning to more systematically clarify the state of play.

Beyond strengthening the links between research and practice and establishing additional opportunities for knowledge exchange and collaboration, there are numerous challenges at a practical level to implementing evidence-based approaches. These challenges run deep, with barriers embedded in science communication training, norms and values that drive practice (e.g., see Jensen and Holliman, 2016).

Evidence-Based Science Communication (EBSC): Pathways Forward

A classic editorial in the British Medical Journal set out to clarify the direction that was being advocated for the field of medicine in an article entitled: “Evidence based medicine: what it is and what it isn't.” We would adopt a similar account for defining “evidence-based science communication” as a viable pathway forward. To adapt the language used by Sackett et al. (1996), p. 71, we are advocating the “conscientious, explicit, and judicious use of current best evidence in making decisions” about science communication. In practice, evidence-based science communication involves combining professional expertise and skills with the best available evidence from systematic research, underpinned by established theory. By professional expertise we mean the “proficiency and judgment” that individual science communication practitioners acquire through experience and practice, refined over time through empirical evaluation (cf. Sackett et al., 1996, p. 71). There are numerous indicators of such professional expertise in science communication, including:

• Applying social science research and theory when designing science communication activities to avoid well-known pitfalls and improve the odds of success.

• Planning, developing, and applying objectives in a logical way to address the needs of specific stakeholders or audiences.

• Following good ethical principles including informed consent for participation and responsible data protection and management.

• Being open and transparent about the nature of the funding, organizations involved and influences on the design of science communication activities

• Ensuring that appropriate and relevant communication skills are developed and applied for a given science communication challenge.

• Being inclusive and welcoming of those who are often marginalized or excluded, both in the development and delivery of science communication activities.

• Willingness and capability to reflect on limitations in one's own communication objectives and strategies despite institutional constraints and agendas, even if this may invalidate previously accepted practices.

• Committing to continually improve practice based on ongoing collection and analysis of evaluation evidence (Jensen, 2014, 2015a).

• Being learning-oriented, focusing on continual professional improvement and sharing of new findings to aid others.

• Working to make any given science communication activity as resource efficient as possible to ensure that opportunities for positive impact are not squandered.

It will be clear from the points above that we believe that “using robust social scientific evidence […] to ensure success should be viewed as a basic necessity across the sector” (Jensen, 2015b, p. 13). Applying well-established principles of good communication (e.g., Spitzberg, 1983) should be a basic expectation of science communication practice for professionals and their funders.

Just as in evidence-based medicine, EBSC must be expected to “invalidate previously accepted” practices and “replace them with new ones that are more powerful, more accurate, more efficacious” (Sackett et al., 1996, p. 71). What counts as effective science communication practice depends on the institutional, local and cultural context. The nature of the science communication evidence base and how to define satisfactory evidence is a matter that requires elaboration aimed at the research community in science communication, which we will develop in a separate essay. Here, we wish to emphasize that science communication research should be providing relevant, accurate, and timely insights that practitioners can use. Indeed, the issues we wish to raise are not only about a deficit of evidence in practice, but also a lack of sufficient applicability, mutual appreciation and collaboration, explained in more detail below (inspired by Heneghan et al., 2017).


We fully recognize that our diagnosis of the problem and perspective on pathways forward will face criticism. Some of that criticism may fall along the lines of prior critiques of evidence-based medicine, including the idea that evidence-based science communication is “old hat,” a “dangerous innovation,” “perpetrated by the arrogant,” and a move to “suppress” science communicators” or researchers' professional “freedom” (Sackett et al., 1996, p. 73). Clearly “evidence” in science communication and beyond will always be contested and provisional, but it nevertheless provides the strongest pragmatic basis for making improvements in practice.

We need to have this debate as a field, including practitioners, researchers and those–like the two of us–that work across these two domains. This commentary is meant to cultivate reflexivity in our community by initiating a discussion about the value, quality, and effectiveness of what we are practicing and researching. Many of the questions posed in and even resulting from this commentary are expected to trigger a discussion about fundamental principles and practices in our field. At the same time, however, we also hope that general issues, such as querying how relevant research should be expected to be for practice, will not overshadow the very concrete issues we are raising about how to use existing evidence and experience on both sides to empower science communication to live up to its potential in the interest of a world that desperately needs it more than ever. This is also why this commentary does not attempt to provide easy solutions but instead welcomes and explicitly invites dialogue about the pathways forward for our field.
