Open Access Under Scrutiny: Can Science Avoid Pandora's Box?
"A critical look at the cOAlition S initiative and the future of scientific publishing in the digital age."
The call for open access to scientific research is growing louder, driven by the promise of immediate and universal access to knowledge. As Carlos Moedas, former European Commissioner for Research, Science and Innovation, stated when introducing cOAlition S, it is about meeting the increasing public demand for reliable information. This initiative aims to make research findings available to everyone, accelerating the pace of discovery and innovation.
However, this transition is not without its challenges. While the principles of open access resonate with many scientists, practical concerns about reliability, organization, and the potential for 'false news' in scientific publishing are emerging. Marc Schiltz, President of Science Europe, emphasizes that science can only function properly if research results are openly available for organized criticism. But how do we ensure quality control in a landscape where information is so easily disseminated?
This article dives into the complexities of open access publishing, questioning whether it truly maximizes the reach and impact of scientific work. We'll explore the perspectives of publishers, researchers, and institutions, examining the potential risks and rewards of this evolving model. Can science avoid opening Pandora's Box as it embraces a new era of accessibility?
Open Access by the Numbers
Open-access articles have grown from an infrequent form of peer-reviewed publication in 2003 to almost half of global publications in 2022, according to the National Center for Science and Engineering Statistics. The STM Open Access Dashboard tracks ten years of uptake across regions, disciplines, countries, and funders. A separate estimate places the open-access publishing market at around $1.6 billion in 2021, representing about 15% of the academic article publishing market. These figures describe different aspects of open access, so they should not be treated as directly interchangeable.
Promise and Friction
Open Access emerged as an alternative to perceived limitations of the subscription-based publishing model, enabled in part by the internet and the World Wide Web. The model has involved a long-running debate over how scientific dissemination should be funded, and one review characterizes the reality as more complicated than a straightforward resolution in favor of Open Access. Researchers, publishers, and readers face different obstacles, reflecting the complexity of knowledge production and dissemination. A 2025 review also reports that the effectiveness of practices such as preregistration and data sharing remains unclear.
From Repositories to Plan S
The history of Open Access can be traced to at least the 1950s, while free online access to journal articles began at least a decade before the term “open access” was formally coined. The movement gained momentum with the arrival of the internet. Key milestones included the Budapest, Bethesda, and Berlin declarations, followed later by global initiatives such as Plan S. The historical record is therefore both technological and institutional, moving from early repositories toward coordinated policy frameworks.
The Shifting Sands of Scientific Publishing: Pay-to-Publish vs. Pay-to-Read
The traditional model of scientific publishing operates on a 'pay-to-read' basis, where readers or institutions must subscribe to journals to access research articles. Open access flips this model, shifting the cost to a 'pay-to-publish' system, where authors or their institutions pay to have their work made freely available. This change raises critical questions about the economics of scientific publishing and its potential impact on quality.

A Broadening Research Landscape
Current Open Access venues span narrative reviews, peer-reviewed research articles, rapid publication platforms, and open peer review. Nature’s Scientific Reviews publishes open-access narrative reviews across the natural sciences, psychology, medicine, and engineering. Frontiers describes itself as an open-access publisher covering the full spectrum of academia, while Gates Open Research combines rapid publication and open peer review with data deposition and sharing. Scientific Research Publishing reports more than 200 open-access journals in science, technology, and medicine, as well as academic books and conference proceedings.
Unresolved Trade-Offs
Open Access may improve the availability of research, but its expansion does not by itself resolve questions about funding, quality control, peer review, or equitable participation. Different publishing models can shift burdens among authors, readers, institutions, and funders. These trade-offs mean that claims of success should be assessed alongside sustainability and research-quality concerns. The available evidence supports a cautious rather than absolute judgment.
Different Models, Different Costs
Comparing subscription and Open Access publishing requires attention to more than whether readers encounter a paywall. The models may differ in who pays, how authors participate, how peer review is organized, and how widely research can circulate. Diamond, repository-based, and publisher-led approaches may also distribute responsibilities differently. Without a common set of measures, broad comparisons should remain provisional.
Navigating the Future of Open Science: A Call for Collaboration and Careful Consideration
The transition to open access is a complex undertaking that requires careful consideration and collaboration. The scientific community must work together to develop sustainable models that support high-quality research while ensuring wider accessibility. This includes exploring alternative funding mechanisms, promoting responsible research assessment, and fostering a culture of transparency and accountability. By embracing a collaborative approach, we can navigate the challenges of open access and unlock the full potential of scientific knowledge for the benefit of all.
Evidence and Judgment
Expert opinion can play a pivotal role in research for decision-making when empirical data are limited or uncertain. A systematic review reports, however, that methods for soliciting, synthesizing, and applying expert input often lack consistency and transparency. It also identifies an absence of cross-disciplinary guidelines for integrating expert opinion into research. For Open Access policy, expert commentary is therefore most useful when its process and evidentiary limits are made explicit.
Policy, AI, and New Publishing Paths
A National Science Foundation-funded workshop report released by MIT Press identifies critical issues in Open Access publishing and policy and considers how they might be addressed. Recent publishing discussions also point toward Open Access mandates, AI in peer review, preprints, and registered reports. Another 2026 overview highlights the rise of diamond Open Access, AI in peer review, preprints, and author copyright reforms. These developments suggest that the future debate will concern infrastructure, governance, and rights as much as access itself.
Access Within a Larger System
Open Access is part of a broader research system rather than an isolated publishing fix. Its effects may depend on funding arrangements, institutional capacity, editorial standards, and the ability of researchers to participate. Expanding readership can coexist with unresolved questions about who bears publishing costs and how quality is maintained. Any systemic assessment should therefore consider both visibility and distribution of burdens.
Research Beyond Academia
Under subscription-based publishing, inventors without access to major journals through universities, laboratories, or companies may have difficulty obtaining scientific publications. Open publishing and advanced online editorial platforms can broaden dissemination, while social media adds another channel and a new dimension to scholarly impact. Springer Nature notes that no single metric fully captures real-world impact, even though Open Access can help research reach beyond academia. Diamond Open Access case-study platforms such as Open Access Cases explicitly aim to connect practical insights with theory.
