University of Groningen

EXECUTIVE SUMMARY AND STRATEGIC VISION

The University of Groningen presents a strong scientific integrity profile, with an overall risk score of -0.125 that indicates a performance slightly more robust than the national baseline. The institution's primary strengths lie in its exceptionally low-risk practices, particularly in avoiding discontinued and institutional journals, and its prudent, better-than-average management of multiple affiliations, retractions, self-citation, and redundant output. Areas requiring strategic monitoring include a higher-than-average exposure to hyper-authorship, hyperprolific authors, and a notable gap between its overall research impact and the impact of work led by its own researchers. This robust integrity framework supports its recognized academic excellence, as evidenced by SCImago Institutions Rankings data placing it among the top national institutions in key fields such as Dentistry (2nd), Economics, Econometrics and Finance (2nd), Chemistry (3rd), and Psychology (4th). The University's mission to "create and share knowledge through outstanding research" is well-served by this low-risk profile; however, the identified vulnerabilities in authorship and impact dependency could challenge the sustainability of this excellence. Ensuring these practices fully align with the highest standards is crucial for fulfilling its societal benefit mandate. Overall, the University of Groningen demonstrates a commendable commitment to scientific integrity, and a strategic focus on refining authorship guidelines and fostering internal research leadership will further solidify its position as a leading international university.

ANALYSIS BY INDICATOR

Rate of Multiple Affiliations

The University of Groningen (Z-score: -0.251) demonstrates a more rigorous management of affiliations than the national standard in the Netherlands (Z-score: -0.033). This prudent profile suggests that while its researchers engage in legitimate collaborations, the institution has effective oversight to prevent the disproportionate use of affiliations as a strategy for "affiliation shopping" or artificially inflating institutional credit. The controlled rate reflects a healthy and transparent approach to academic partnerships.

Rate of Retracted Output

With a Z-score of -0.353, the institution maintains a more cautious profile regarding retracted publications compared to the national average of -0.277. This suggests the presence of robust pre-publication quality control mechanisms. While some retractions can signify responsible error correction, a consistently low rate, as seen here, points towards effective systemic checks that successfully prevent recurring malpractice or methodological flaws, thereby reinforcing the integrity and reliability of its research output.

Rate of Institutional Self-Citation

The university exhibits a healthier pattern of citation than its national peers, with a Z-score of -0.482 that is significantly lower than the country's average of -0.383. This prudent management indicates a strong integration within the global scientific community and a reduced risk of operating in an academic "echo chamber." By avoiding disproportionately high rates of self-citation, the institution ensures its academic influence is validated by broad external scrutiny rather than being potentially inflated by endogamous internal dynamics.

Rate of Output in Discontinued Journals

The university's performance (Z-score: -0.499) is in perfect alignment with the national environment in the Netherlands (Z-score: -0.494), which itself demonstrates maximum security in this area. This integrity synchrony reflects a shared and effective commitment to avoiding problematic publication venues. It indicates that researchers are exercising excellent due diligence in selecting high-quality, reputable journals, thereby mitigating the severe reputational and resource risks associated with "predatory" or low-quality publishing practices.

Rate of Hyper-Authored Output

The institution shows a greater tendency toward hyper-authored publications than the national average, with a Z-score of 1.305 compared to the country's 0.843. This indicates a high exposure to the risks associated with this practice. While extensive author lists are legitimate in "Big Science," this elevated rate warrants a closer look to ensure it reflects genuine massive collaboration rather than a dilution of individual accountability through "honorary" or political authorship, which could obscure the true contributions of researchers.

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

The university displays a significantly wider gap between its overall publication impact and the impact of research where it holds a leadership role (Z-score: 0.602 vs. country's 0.085). This high exposure suggests a greater-than-average reliance on external partners for high-impact work, signaling a potential sustainability risk where scientific prestige may be more dependent and exogenous than structural. This finding invites a strategic reflection on whether its excellence metrics stem from its own core capacities or from its positioning in collaborations where it does not exercise primary intellectual leadership.

Rate of Hyperprolific Authors

The institution exhibits a higher concentration of hyperprolific authors than is typical for the Netherlands, with its Z-score of 0.837 notably exceeding the national average of 0.444. This high exposure signals a potential imbalance between the quantity and quality of output. Extreme individual publication volumes can challenge the limits of meaningful intellectual contribution and may point to underlying risks such as coercive authorship or the assignment of credit without real participation, which prioritize metrics over the integrity of the scientific record.

Rate of Output in Institutional Journals

The university's practices regarding publishing in its own journals (Z-score: -0.268) are in complete harmony with the secure national standard (Z-score: -0.245). This integrity synchrony reflects a shared understanding of the potential conflicts of interest inherent in such publications. This alignment demonstrates a strong commitment to independent external peer review, ensuring that research is validated competitively and globally, rather than risking academic endogamy by using internal channels as potential "fast tracks" to inflate publication records.

Rate of Redundant Output

The institution manages the risk of redundant publications with more rigor than the national standard, as shown by its lower Z-score of -0.448 compared to the country's -0.302. This prudent profile suggests a culture that values substantial contributions over artificially inflated publication counts. By minimizing the practice of "salami slicing"—dividing a single coherent study into minimal publishable units—the university upholds the integrity of the scientific evidence base and prioritizes the generation of significant new knowledge.
