Should Scientists Be Advocates? Where the Line Is
The question of whether scientists should advocate for the policies their research supports comes up often in ocean science.
The issue matters because the stakes are high. Ocean ecosystems are under pressure, species are declining, and many decisions are being made under time constraints and uncertainty. In that context, some researchers feel a responsibility to speak more directly about the implications of their work and the work of their colleagues. Others worry that doing so can blur the line between evidence and political position.
This piece does not try to settle the debate. It aims instead to describe the range of views and the considerations that usually shape it.
What people mean by advocacy
It helps to be clear about what “advocacy” means, because the word covers a wide range of activities.
At one end is the straightforward communication of findings and their implications. Explaining that current fishing pressure appears incompatible with stock recovery is part of science communication.
At the other end is explicit support for a particular political outcome, such as campaigning for a specific law, candidate, or party position. That is a different kind of activity, and for some, it raises different questions.
Between those two points is what could be seen as a middle ground: speaking to the media, writing opinion pieces, engaging with NGOs, attending policy meetings, or making the case for urgent action based on the evidence. Whether those activities are viewed as advocacy depends on the setting, the role of the scientist, and the expectations of the audience.
Scientists as experts and people
One useful distinction is between speaking as a scientist and speaking as a person who happens to be a scientist.
Scientists provide evidence through their research and expertise. But they are also people, with values, opinions, and civic views that may or may not fall within their field of expertise. The important question is not whether those personal views exist (they do) but when someone is speaking from evidence and when they are speaking from personal judgment or moral conviction.
That distinction matters because it avoids two common mistakes. The first is pretending that scientists have no values at all. The second is assuming that every public statement by a scientist is scientific evidence rather than personal opinion.
A scientist may be fully justified in saying, “The evidence suggests this policy would have these consequences.” They may also, separately, say, “As an individual, I believe this issue deserves urgent action.” Those are related, but they are not the same statement.
Arguments for engagement
One view is that scientists should not limit themselves to publishing findings and leaving others to interpret them, particularly given some of the vast crises we and the natural world are facing. From this perspective, if research has clear implications for decisions, it can be reasonable for scientists to help explain those implications more directly.
Supporters of this view also note that communication choices are never entirely neutral. Decisions about what to emphasise, how to frame uncertainty, and when to speak all shape how research is received. In that sense, complete detachment may be less common in practice than it appears in principle.
There is also a practical argument. In many ocean issues, researchers who communicate clearly and consistently are more likely to be heard than those who stay entirely within academic publication channels. That does not mean advocacy is always necessary, but it does suggest that visibility and clarity can matter.
Arguments for caution
There are also good reasons some scientists prefer to stay cautious.
Scientific credibility can be affected if researchers are seen as starting from a pre-determined position or personal opinion and then selecting evidence to support it. Even when that is not what is happening, the perception can still matter, especially in contentious public debates.
There is also a question of role. Scientists are trained to produce and evaluate evidence. They are not always trained to weigh competing policy priorities, political constraints, or distributional trade-offs. A researcher may be well qualified to explain what the evidence suggests, but is not necessarily the best person to judge which policy should be adopted.
Institutional context matters too. Universities, research organisations, and government bodies may have different expectations about public statements and external engagement. In some settings, individual advocacy may sit comfortably within those expectations. In others, it may create complications.
A practical line
Rather than asking whether scientists should always advocate or never advocate, it may be more useful to ask what kind of contribution is appropriate in a given context.
A few questions help:
What does the evidence support?
What parts of the issue are scientific, and what parts are value-based or political?
What role does the scientist have, and what do their institution and audience expect?
Would speaking more directly improve understanding, or risk undermining trust?
This framing keeps the focus on judgment rather than principle alone. It also leaves room for different scientists to draw the line differently in different situations.
Trust and responsibility
Whatever position someone takes, trust is central. Scientists are generally most effective when they are accurate, transparent, and clear about what their evidence does and does not show.
That does not require avoiding all public engagement. Nor does it require taking a public stance on every issue. It does suggest that scientists should be careful about how they present uncertainty, how they separate evidence from personal values, and how they describe the limits of their expertise.
