Open knowledge platforms have transformed how societies access, interpret, and apply information. Among these, Wikipedia stands as the world’s largest collaboratively produced repository of human knowledge, influencing not only public understanding but also the decisions of policymakers, journalists, and institutions. This paper explores the mechanisms through which open knowledge—particularly Wikipedia—affects decision-making processes at governmental, organizational, and societal levels. Drawing on interdisciplinary studies in information science, public policy, and data ethics, it argues that Wikipedia functions as both a knowledge infrastructure and a policy actor. The analysis highlights three key pathways of influence: (1) information diffusion and agenda-setting, (2) epistemic authority and legitimacy, and (3) the feedback loop between open knowledge production and institutional policymaking. The paper concludes by suggesting governance frameworks that balance openness, accuracy, and accountability in the digital public sphere.

1. Introduction: Knowledge Openness and the New Information Order
The past two decades have witnessed an unprecedented democratization of information. Platforms like Wikipedia, Wikidata, and OpenStreetMap have redefined who can create, verify, and disseminate knowledge (Jemielniak & Aibar, 2016). Wikipedia alone hosts over six million English-language articles and operates in more than 300 languages, generating billions of page views monthly (Wikimedia Foundation, 2024).
Traditionally, policymaking relied on expert committees, academic research, and official statistics. However, the networked information environment has blurred the boundaries between expert and lay knowledge (O’Neil, 2014). Today, open-access resources such as Wikipedia are not merely passive repositories—they are active epistemic infrastructures that shape the information ecosystem within which policy decisions occur.
This paper examines how open knowledge platforms, with Wikipedia as a case study, influence decision-making processes. It argues that Wikipedia contributes to policy in three main ways: by framing issues through information diffusion, by establishing epistemic legitimacy, and by creating feedback loops between open collaboration and institutional knowledge systems.
2. Information Diffusion and Agenda-Setting
The first mechanism through which open knowledge affects policy is information diffusion—the process by which freely available knowledge shapes the public and institutional agenda.
Research shows that Wikipedia’s visibility in search engine results grants it a disproportionate role in information dissemination (Messner & South, 2011). Policymakers, journalists, and NGOs often rely on Wikipedia as an entry point for understanding complex topics. A 2020 study by Lewoniewski et al. found that over 85% of journalists across Europe consult Wikipedia when preparing background information for political reporting. Similarly, government agencies often reference Wikipedia entries indirectly when producing public communication materials (Janssen & Kuk, 2016).
Wikipedia’s editorial model also allows for rapid updates in response to crises or emerging issues. During the COVID-19 pandemic, Wikipedia’s medical content became a crucial knowledge intermediary, synthesizing data from peer-reviewed journals and public health authorities (Zagorova et al., 2021). As these articles were widely consulted by policymakers and the media, the platform played an unacknowledged yet significant role in agenda-setting—determining which issues gained visibility and urgency.
In this sense, Wikipedia functions as an informational commons where competing narratives are negotiated in real time. Policy discussions are indirectly shaped by the salience of topics within this digital knowledge ecosystem.
3. Epistemic Authority and the Legitimacy of Open Knowledge
The second dimension of influence concerns epistemic authority—the power to define what counts as valid knowledge. Traditionally, authority in policymaking rested with experts, institutions, and scientific consensus. Wikipedia challenges this hierarchy by relying on distributed peer production and collective verification.
Despite critiques of reliability, several studies have demonstrated that Wikipedia’s accuracy in scientific and technical domains rivals that of expert encyclopedias (Giles, 2005; Mesgari et al., 2015). The platform’s open referencing norms, verifiability policies, and transparent edit histories have established it as a credible, if unconventional, source of knowledge.
Policymakers increasingly cite Wikipedia as a boundary object—a resource that mediates between expert knowledge and public understanding (Jasanoff, 2017). For example, European Union reports on digital literacy and misinformation reference Wikipedia as both a data source and a model for participatory governance (European Commission, 2022).
This recognition has a normative dimension: open knowledge systems expand epistemic inclusivity by allowing contributions from citizens, activists, and non-Western perspectives. In doing so, they challenge knowledge asymmetries in global policymaking. However, epistemic openness also entails vulnerability—biases, edit wars, and data manipulation remain ongoing challenges.
4. Feedback Loops Between Open Knowledge and Policy Institutions
The relationship between open knowledge and policy is not unidirectional. Increasingly, governments and international organizations are feeding data back into open platforms to improve transparency and accessibility.
For instance, the European Parliament’s Open Data Portal and the United Nations’ Sustainable Development Goals (SDG) indicators now collaborate with Wikidata, allowing structured policy data to circulate freely across languages and systems (Auer et al., 2020). This interoperability strengthens the feedback loop between open collaboration and institutional decision-making.
Similarly, NGOs and academic consortia use Wikipedia as a policy communication interface, translating research findings into publicly digestible knowledge. This practice enhances accountability while bridging the gap between science and policy. Yet, it also raises governance questions: Who curates this knowledge? How is neutrality maintained?
Open knowledge governance thus requires hybrid mechanisms—community-based oversight combined with institutional partnership frameworks—to ensure both openness and reliability (Tkacz, 2015).
5. Policy Implications: Openness, Accountability, and Trust
Recognizing Wikipedia’s influence on decision-making compels policymakers to rethink how knowledge infrastructures are integrated into governance. Three implications stand out:
Epistemic Transparency: Policymakers should disclose when open knowledge sources inform decisions, enhancing public trust and accountability.
Collaborative Knowledge Governance: Institutions should partner with open knowledge communities to co-develop guidelines for reliability, referencing, and data integrity.
Digital Literacy and Critical Capacity: Governments should promote education that enables citizens—and civil servants—to critically assess open sources, avoiding misinformation while embracing transparency.
Such measures can convert open knowledge from an informal influence into a recognized pillar of evidence-based policymaking.
6. Conclusion: Open Knowledge as Policy Infrastructure
Wikipedia and related platforms embody a profound shift in how knowledge is produced and legitimized. Their influence on policymaking lies not in formal citation but in the epistemic environments they shape—the frameworks within which information is sought, trusted, and acted upon.
As open knowledge becomes intertwined with the architecture of governance, the boundary between citizen participation and institutional expertise continues to blur. The challenge for policymakers is no longer whether to engage with open knowledge, but how to do so responsibly.
Ultimately, transforming open knowledge into a constructive policy asset requires embracing its pluralism while safeguarding its credibility. In this evolving landscape, Wikipedia stands not merely as an encyclopedia but as an engine of civic epistemology—a living negotiation of what society knows and how it decides.
