Reproducibility

Replicability and reproducibility are increasingly recognized as essential to scientific progress and integrity.

Open science practices play an essential role in supporting these concepts. Replicability (or the extent to which the design, implementation, analysis, and reporting of a study enable a third party to repeat the study and assess its findings), is highly dependent on the openness of, for example, research protocols, methods and data. We cannot replicate research if we have insufficient information about the original study.

Openness in science is therefore a vital driver of replicability. Replication, in turn, allows for an assessment of reproducibility, (or the extent to which the results of the original study agree with those of replication studies - see the figure below). In the end, reproducibility increases our confidence in research findings and promotes the credibility and reliability of science, and open science practices are essential to achieve this goal.

About

Open Science is a set of principles and practices that aim to make scientific research from all fields accessible to everyone for the benefit of scientists and society as a whole; it is about making sure not only that scientific knowledge is accessible, but also that the production of that knowledge itself is inclusive, equitable and sustainable (definition by UNESCO).

Life cycle and taskforce

Radboud University and our research institute (Radboudumc Research Institute for Medical Innovation) see Open Science as the norm in 2030.

This means much more than publishing all papers in Open Access journals. Open Science is about increasing impact in the scientific and societal domains by sharing research materials and codes, making data available for reuse, enhancing reproducibility of research, and involving all relevant stakeholders, including citizen and patients. Our research institute's taskforce (the Open Science Taskforce) is there to stimulate the cultural, policy and professional changes to roll out Open Science in its fullest scope.

The entire research cycle can be open. The taskforce focuses on four domains:

  • Open Access
  • Open and FAIR data
  • Citizen Science and Public Engagement
  • Reproducibility

Four domains


Open Access

Open Access publishing ensures free and unrestricted access to scientific knowledge, promoting transparency, education, and innovation without publisher-imposed copyright barriers.

Open Access

Open Access publishing ensures free and unrestricted access to scientific knowledge, promoting transparency, education, and innovation without publisher-imposed copyright barriers. For researchers, it enhances visibility, boosts citation potential, and amplifies the overall impact of their work.
Radboudumc fully endorses the principles of Open Access and actively monitors the percentage of articles made openly available. In 2025, 94% of publications from Radboudumc (co-)authors were published Open Access. This is a milestone we are proud of, but our work does not stop here. We remain committed to advancing publishing practices that are Open, Fair, and of the highest quality, ensuring that scientific knowledge is accessible to all and contributes to better healthcare and innovation.
Additional information about Open Access can be found on the general website on Open Access.



FAIR data and open data

The FAIR (acronym for Findable, Accessible, Interoperable and Reusable) principles help to make your data ready for reuse. All data should be FAIR, and some data can be open.

FAIR data and open data

Making your data available for other researchers increases the visibility of your scientific achievements and allows your data to have an impact beyond your research project and publications. The FAIR (acronym for Findable, Accessible, Interoperable and Reusable) principles help to make your data ready for reuse. However, FAIR data is not always open data.



Citizen Science and public engagement

Citizen Science refers to the participation of lay people or non-professional scientists in scientific research. Their participation can take place in various fields, on different levels and in different research phases.
