Vrije Universiteit Amsterdam

EXECUTIVE SUMMARY AND STRATEGIC VISION

Vrije Universiteit Amsterdam demonstrates a robust institutional commitment to scientific integrity, reflected in an overall risk score of -0.099, which indicates a very low-risk profile. The institution exhibits exceptional control over key integrity areas, particularly in the selection of publication venues, management of self-citation, and avoidance of academic endogamy. However, this strong foundation is contrasted by notable vulnerabilities in authorship practices, specifically concerning hyper-authorship and hyper-prolificacy, and a significant gap in the impact of institution-led research versus collaborative output. These areas of concern require strategic attention, as they could potentially undermine the university's mission to generate "innovations and insights that contribute to a better world." The university's outstanding international reputation, evidenced by its SCImago Institutions Rankings in world-leading areas such as Dentistry, Medicine, Psychology, and Biochemistry, Genetics and Molecular Biology, is built on a perception of excellence and social responsibility. Unaddressed risks in authorship transparency and impact sustainability could create a disconnect between this public mission and internal research practices. Therefore, it is recommended that the university leverages its solid integrity framework to develop targeted policies that refine authorship criteria and foster greater intellectual leadership, ensuring its operational practices fully align with its ambitious vision for societal impact.

ANALYSIS BY INDICATOR

Rate of Multiple Affiliations

The institution presents a Z-score of -0.690, which is significantly lower than the national average of -0.033. This demonstrates a prudent and rigorous approach to managing researcher affiliations, surpassing the already high standard set by the national context. While multiple affiliations are often a legitimate result of researcher mobility or partnerships, the university's controlled rate suggests that its collaborative frameworks are well-defined, effectively mitigating the risk of strategic "affiliation shopping" or attempts to artificially inflate institutional credit through ambiguous attributions.

Rate of Retracted Output

With a Z-score of -0.343, the institution shows a lower incidence of retracted publications compared to the national average of -0.277. This prudent profile suggests that the university's internal quality control mechanisms are more rigorous than the national standard. Retractions can be complex, sometimes reflecting responsible error correction. However, a rate this low indicates that pre-publication processes for ensuring methodological rigor and data integrity are likely very effective, preventing systemic failures and safeguarding the institution's reputation for reliable science.

Rate of Institutional Self-Citation

The institution's Z-score for self-citation is -0.466, notably lower than the national average of -0.383. This indicates a prudent profile, suggesting that the university's research is validated externally to a greater degree than its national peers. A certain level of self-citation is natural, but the institution's low rate demonstrates a healthy integration into the global scientific conversation, avoiding the "echo chambers" that can arise from endogamous practices. This ensures that its academic influence is a result of broad community recognition rather than being inflated by internal dynamics.

Rate of Output in Discontinued Journals

The institution's Z-score of -0.500 is almost identical to the national average of -0.494, demonstrating perfect integrity synchrony with an environment of maximum scientific security. This alignment reflects a shared, robust commitment to quality publishing channels. A low rate is critical, as it indicates that researchers are performing excellent due diligence in selecting dissemination media. This practice protects the institution from the severe reputational risks associated with "predatory" or low-quality journals and ensures that research resources are invested in impactful and ethically sound outlets.

Rate of Hyper-Authored Output

The institution exhibits a Z-score of 1.345, a significant risk level that markedly exceeds the national average of 0.843. This finding suggests an accentuation of risk, where the university amplifies a vulnerability already present in the national system. While extensive author lists are legitimate in "Big Science" disciplines, a high rate outside these contexts can signal author list inflation, which dilutes individual accountability and transparency. This indicator serves as a critical alert to review authorship practices and distinguish between necessary massive collaboration and potentially inappropriate "honorary" or political authorship.

Gap between Impact of total output and the impact of output with leadership

With a Z-score of 0.503, the institution shows a much higher exposure to this risk compared to the national average of 0.085, even though both fall within the medium-risk category. This wide positive gap signals a potential sustainability risk, suggesting that the institution's overall scientific prestige may be heavily dependent on external partners rather than being structurally generated from within. This finding invites a strategic reflection on whether the university's high-impact metrics result from its own internal capacity and intellectual leadership or from a strategic positioning in collaborations where it does not lead.

Rate of Hyperprolific Authors

The institution's Z-score of 1.430 indicates a high exposure to this risk, substantially surpassing the national average of 0.444. This suggests the university is more prone to hosting authors with extreme publication volumes than its peers. While high productivity can reflect leadership, volumes exceeding 50 articles a year challenge the plausible limits of meaningful intellectual contribution. This high indicator alerts to potential imbalances between quantity and quality, pointing to risks such as coercive authorship or the assignment of authorship without real participation—dynamics that prioritize metrics over the integrity of the scientific record.

Rate of Output in Institutional Journals

The institution's Z-score of -0.259 is in close alignment with the national average of -0.245, indicating integrity synchrony with a national environment that avoids academic endogamy. By not depending excessively on its own journals, the university mitigates potential conflicts of interest where it would act as both judge and party. This practice ensures that its scientific production undergoes independent external peer review, which is fundamental for achieving global visibility and competitive validation, rather than using internal channels as potential "fast tracks" to inflate publication counts.

Rate of Redundant Output

The institution's Z-score of -0.255 is very close to the national average of -0.302, reflecting a state of statistical normality. This indicates that the risk level for this practice is as expected for its context and size. The low value suggests that the university's researchers are not engaging in "salami slicing"—the practice of dividing a coherent study into minimal publishable units to artificially inflate productivity. This commitment to publishing complete, significant work upholds the integrity of the scientific evidence base and avoids overburdening the peer-review system.
