Scientific progress depends on research that is both reliable and transparent, yet achieving this remains a persistent challenge. This year’s winner of the Einstein Foundation Institutional Award, the Brazilian Reproducibility Initiative, brought together over 200 researchers from across Brazil to replicate and evaluate published biomedical experiments. Beyond measuring reproducibility, the Initiative created a collaborative platform where scientists learned from each other’s successes and failures, fostering a culture of openness and rigor nationwide. 
 

What if an entire country could take a long, hard look at its scientific practices? For the Brazilian Reproducibility Initiative, that’s exactly what happened. Founded as a national, open consortium, the Initiative brought together 213 researchers from 56 laboratories across Brazil to attempt 143 replications of 56 experiments using widely applied lab methods. The results, published as a preprint, revealed replication rates ranging from 15 to 45%, depending on criteria, while also uncovering factors that predict replication success. 

“It has been impressive to watch the Initiative develop and progress,” states Tim Errington, Senior Director of Research, Center for Open Science, Institutional Award Winner 2021. 
 

Yet the Initiative’s value extends far beyond replication numbers. Following dozens of laboratories as they tried to replicate published findings, the project revealed challenges not only in the literature but also within the replicating teams themselves. Limited infrastructure, variability in protocols, and differences in training and project coordination all shaped outcomes. Through systematic self-assessment, participants identified concrete ways to improve scientific practices, including harmonizing terminologies, improving protocol development, and strengthening data management. 

“The most important outcome was watching labs as they tried to replicate studies,” says Olavo Amaral, the Initiative’s coordinator. “It became clear that the process itself – confronting what works, what doesn’t, and what needs improvement – teaches lessons about collaboration, transparency, and scientific rigor that go far beyond the replication numbers.” 
 

The Initiative also sparked lasting change in Brazil’s research ecosystem. It led to the creation of BRISA, a collaborative platform for systematic reviews and metaanalyses in preclinical research, providing hands-on training in rigorous research methods. It also gave rise to the Brazilian Reproducibility Network (BRN), connecting researchers, groups, and institutions across disciplines to advance transparency, reproducibility, and collaboration. 
 

In 2024, the Network provided CAPES, the national graduate program evaluation agency, with recommendations to foster open and reproducible science, which were followed by concrete policy changes at the national level. “The Initiative showed that large-scale, confirmatory research can thrive only when the scientific community works collectively, with the right incentives and infrastructure,” Amaral explains. “By involving researchers as both participants and evaluators, we built legitimacy and engagement. People learned by doing, and by reflecting critically on their own practices.” 
 

Despite being based in a middle-income country with comparatively limited funding, the Initiative is one of the largest coordinated replication effort in laboratory biology worldwide. Its focus on a single country maximized its impact on local labs, institutions, and funding bodies, while its open, collaborative design fostered education, motivation, and a culture of reform. As one participating researcher noted, “Being part of this groundbreaking project has shifted our lab’s approach toward more transparent and reproducible science.” 
 

The Initiative’s accomplishments have attracted international attention and support, with experts noting that it offers a replicable model for other countries seeking to strengthen research quality. Its impact continues through the BRN, which curates open educational resources, fosters training, and engages with policy-making bodies to integrate open science into national research strategies. 
 

The €100,000 Einstein Foundation Award will help ensure the Initiative’s data is analyzed in depth and that the Brazilian Reproducibility Network remains sustainable, supporting new collaborative projects, educational activities, and advocacy for research quality across the country. 

“The Initiative demonstrates that collective effort, transparency, and openness can transform science. This award will help us continue building capacity for rigorous, reproducible, and collaborative research in Brazil – and, we hope, provide a model for other countries.” (Olavo Amaral, Coordinator Brazilian Reproducibility Initiative)
 

By combining large-scale replication, systematic selfassessment, and community-driven reform, the Brazilian Reproducibility Initiative exemplifies how rigorous, open, and collaborative science can drive lasting change. Its legacy is not only in its data but in the culture of research it continues to inspire – one in which transparency, reproducibility, and collective responsibility are the foundations of progress.
