Five Fault Lines to Watch in Science Diplomacy
Understanding science diplomacy today: Part 5 of a five-part introductory series.
This is Part 5 of a five-part introductory series on science diplomacy.
Science diplomacy evolves in shifts along fault lines: structural tensions where cooperation, competition, and political pressure intersect.
Watching how they develop offers a clearer guide to where cooperation may hold, where it may fracture, and how the role of science in international affairs is likely to change. Here are five fault lines to watch:
Openness Versus Control
The most persistent fault line lies between openness and control.
Scientific cooperation depends on openness: shared data, open exchange, and the mobility of researchers. At the same time, governments increasingly view science and technology through lenses of security, competitiveness, and resilience.
This tension will be managed unevenly across sectors and countries. Some areas of science will remain relatively open; others will become tightly regulated or selectively shared. Science diplomacy will increasingly operate within this narrowed space, tasked with preserving limited cooperation without undermining national controls.
How countries draw and redraw these boundaries will shape the future scope of international scientific engagement.
As Ahmed Zewail, a Nobel laureate in chemistry and former U.S. science envoy to the Middle East, observed in a 2010 essay on science diplomacy: “The soft power of science has the potential to reshape global diplomacy.”
His observation underscored how scientific openness and the values it embodies can function as a bridge even when political relations are strained.
Fragmentation of Scientific Systems
A second fault line is fragmentation.
Rather than a single global scientific system, parallel research ecosystems are emerging. These systems differ in standards, norms, governance models, and political alignment. Cooperation increasingly occurs within blocs rather than across them.
This fragmentation complicates coordination on global challenges that depend on shared data, interoperable systems, and mutual trust. It also raises questions about whose standards prevail, whose data are accepted, and whose expertise is recognized.
Science diplomacy may help manage the interfaces between fragmented systems. It cannot restore a fully unified scientific order.
Inequality and Inclusion
A third fault line concerns inequality.
Scientific capacity remains unevenly distributed, and those disparities shape whose priorities drive international agendas. Even cooperative frameworks designed to be inclusive can reinforce asymmetries in influence, access, and benefit.
Efforts to address these gaps through capacity building, data sharing, and institutional reform will remain central to science diplomacy. They will also face political and financial constraints, particularly as competition intensifies.
Whether science diplomacy can meaningfully reduce inequality, or merely manage it, will be a defining test of its credibility.
Anticipation Versus Reaction
A fourth fault line lies between anticipation and reaction.
Much of science diplomacy remains reactive, responding to crises after they emerge. At the same time, there is growing interest in anticipatory approaches: foresight, early warning, and horizon scanning that link scientific insight to diplomatic planning.
Initiatives such as those promoted by the Geneva Science and Diplomacy Anticipator foundation reflect this shift toward anticipation. They aim to integrate scientific foresight into international decision-making before risks escalate into crises.
The challenge is translation. Foresight can inform choices, but it does not override political incentives or institutional inertia. Whether anticipatory science diplomacy becomes routine or remains marginal is still an open question.
Trust Under Pressure
The final and most consequential fault line is trust.
Science diplomacy depends on trust in expertise, institutions, and procedures. That trust is increasingly fragile, challenged by politicization, disinformation, and competing claims to authority.
Trust is unlikely to be rebuilt through appeals to neutrality alone. It will depend on transparency, accountability, and repeated demonstration of value under difficult conditions.
Science diplomacy may not restore broad confidence in science or international institutions, but it can help sustain functional trust in specific contexts, allowing cooperation to continue where interests align and risks are shared.
What These Fault Lines Reveal
Taken together, these fault lines point to a more constrained and contested role for science diplomacy.
While it may not resolve geopolitical rivalry or eliminate structural inequalities, and its influence may be uneven, situational, and often indirect, science diplomacy remains relevant because it operates where other diplomatic tools are limited.
Understanding science diplomacy today requires recognizing both its potential and its limits, and watching closely how these fault lines shift over time.
Closing the Series
This introductory series has examined what science diplomacy is, who practices it, how it works, where it breaks down, and the pressures shaping its future.
Science diplomacy is neither a cure-all nor a relic. It is a set of practices evolving under strain, reflecting broader transformations in science, technology, and global affairs.
Watching its fault lines offers a clearer view of where cooperation remains possible — and where it will be hardest to sustain.
Editor’s Note:
This five-part series was intended as an introduction to science diplomacy as it is practiced today, not as a definitive account or a policy prescription. The aim has been to clarify how scientific knowledge, institutions, and expertise intersect with diplomacy in modern politics and technology.
Future coverage in The Science Diplomat will build on these foundations, examining specific domains, institutions, and developments as they unfold.
