Erasmus University Rotterdam

EXECUTIVE SUMMARY AND STRATEGIC VISION

Erasmus University Rotterdam demonstrates a robust scientific integrity profile, reflected in an excellent overall score of -0.120. The institution exhibits particular strength in its operational diligence, with very low risk signals in areas such as publication in discontinued journals, institutional self-publication, and redundant output, indicating a strong foundation of responsible research practices. This operational integrity supports its world-class academic standing, particularly in thematic areas like Business, Management and Accounting; Economics, Econometrics and Finance; and Medicine, where it holds top-tier positions according to SCImago Institutions Rankings data. However, a cluster of risks related to authorship and collaboration patterns—specifically in hyper-authorship, hyper-prolificacy, and a dependency on external partners for impact—presents a strategic challenge. These vulnerabilities could subtly undermine the university's mission to "create a positive impact on societal challenges," as an overemphasis on collaborative metrics without ensuring internal intellectual leadership and individual accountability may compromise the sustainability and authenticity of its contributions. To fully align its practices with its mission, a strategic review of authorship policies and a focus on fostering internal research leadership are recommended to ensure its significant impact is both genuine and enduring.

ANALYSIS BY INDICATOR

Rate of Multiple Affiliations

With an institutional Z-score of -1.016 compared to the national score of -0.033, the university's performance shows a commendable absence of risk signals, placing it in a more secure position than the already low-risk national standard. This demonstrates a clear and unambiguous approach to academic affiliation. The very low rate of multiple affiliations indicates that the institution is not exposed to practices like “affiliation shopping” or strategic attempts to artificially inflate institutional credit, ensuring that its collaborative footprint is transparent and accurately represented.

Rate of Retracted Output

The institution's Z-score of -0.259 is statistically normal and fully aligned with the national context (Z-score: -0.277). This suggests a healthy equilibrium in its scientific process, where post-publication corrections are managed at an expected rate. The data does not point to systemic failures in pre-publication quality control mechanisms; rather, it reflects a standard operational dynamic of scientific self-correction that is consistent with its peers and indicates responsible supervision of the research record.

Rate of Institutional Self-Citation

The institution maintains a prudent profile regarding self-citation (Z-score: -0.643), managing this indicator with greater rigor than the national standard (Z-score: -0.383). This lower-than-average rate is a positive sign of broad external engagement and validation from the global scientific community. It effectively mitigates the risk of creating scientific 'echo chambers' or endogamous impact inflation, confirming that the institution's academic influence is driven by external recognition rather than being oversized by internal dynamics.

Rate of Output in Discontinued Journals

There is a complete synchrony between the institution (Z-score: -0.497) and the national environment (Z-score: -0.494), both demonstrating maximum security against publishing in problematic journals. This alignment reflects excellent due diligence in the selection of dissemination channels by its researchers. The near-total absence of output in discontinued journals constitutes a critical safeguard, confirming that institutional resources are not being wasted on 'predatory' or low-quality media and protecting its scientific reputation.

Rate of Hyper-Authored Output

This indicator signals a significant area of concern, as the institution (Z-score: 1.362) not only reflects but amplifies a national vulnerability towards hyper-authorship (Z-score: 0.843). With a score considerably higher than the country's medium-risk level, there is an urgent need to investigate authorship practices. While extensive author lists are legitimate in 'Big Science' contexts, this high rate suggests a potential for author list inflation, which can dilute individual accountability and transparency. It is critical to distinguish between necessary massive collaboration and the possibility of 'honorary' or political authorship practices that could compromise research integrity.

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

The institution shows a high exposure to dependency on external collaboration for its citation impact (Z-score: 0.646), a risk that is significantly more pronounced than the national average (Z-score: 0.085). The wide positive gap, where overall impact is notably higher than the impact of research led by the institution, signals a potential sustainability risk. This suggests that its scientific prestige may be more dependent and exogenous than structural. This finding invites a strategic reflection on whether its high-ranking excellence metrics result from genuine internal capacity or from strategic positioning in collaborations where the institution does not consistently exercise intellectual leadership.

Rate of Hyperprolific Authors

The rate of hyperprolific authors at the institution (Z-score: 1.425) is a point of high exposure, markedly exceeding the average for its national environment (Z-score: 0.444). While high productivity can evidence leadership, such an elevated score challenges the plausible limits of meaningful intellectual contribution for a notable number of individuals. This alert points to potential imbalances between quantity and quality, and raises the possibility of underlying risks such as coercive authorship or the assignment of authorship without substantive participation—dynamics that prioritize metric inflation over the integrity of the scientific record.

Rate of Output in Institutional Journals

The institution (Z-score: -0.240) demonstrates perfect alignment with the national standard (Z-score: -0.245), which is characterized by maximum security in this area. The very low rate of publication in its own journals is a strong indicator of its commitment to independent, external peer review. This practice avoids potential conflicts of interest and the risk of academic endogamy, ensuring its scientific production is validated through standard competitive channels and enhancing its global visibility and credibility.

Rate of Redundant Output

The institution (Z-score: -0.562) exhibits an exemplary low-profile consistency, with a near-total absence of signals related to redundant publications, a standard that surpasses the already low-risk national benchmark (Z-score: -0.302). This indicates a strong institutional culture that prioritizes substantive contributions over artificially inflating publication volume. The data suggests that researchers are focused on presenting coherent studies rather than engaging in 'salami slicing' by fragmenting data into minimal publishable units, a practice that upholds the quality of scientific evidence.
