Sorbonne Universite

EXECUTIVE SUMMARY AND STRATEGIC VISION

Sorbonne Université presents a globally balanced scientific integrity profile, with an overall risk score of -0.114 that indicates a solid foundation but also highlights specific areas for strategic improvement. The institution demonstrates notable strengths in its publication practices, with very low risk signals for output in discontinued or institutional journals, and a commendable resilience against national trends in multiple affiliations. These strengths align with its world-class research standing, as evidenced by its leadership in the SCImago Institutions Rankings, particularly in fields such as Earth and Planetary Sciences, Arts and Humanities, Biochemistry, and Medicine. However, the analysis reveals significant vulnerabilities in hyper-authorship and a medium-level risk concerning its dependency on external leadership for impact. These indicators could challenge the core of its mission, which is rooted in a "humanist tradition" and the responsible development and sharing of knowledge. Practices that dilute individual accountability or suggest an over-reliance on external partners may undermine the goal of fostering genuine internal capacity and transparently contributing to society. By proactively addressing these specific vulnerabilities, Sorbonne Université can further solidify its position as a global leader, ensuring its operational practices fully reflect its stated commitment to excellence and integrity.

ANALYSIS BY INDICATOR

Rate of Multiple Affiliations

The institution presents a Z-score of -0.236, a low-risk value that contrasts with the national average of 0.648, which falls into the medium-risk category. This demonstrates a notable institutional resilience, suggesting that Sorbonne Université's internal control mechanisms are effectively mitigating systemic risks that are more prevalent across the country. While multiple affiliations can be a legitimate outcome of researcher mobility and partnerships, the university's contained rate indicates that it is successfully avoiding practices that could be perceived as strategic attempts to inflate institutional credit or "affiliation shopping," thereby maintaining a clear and robust affiliation profile compared to its national peers.

Rate of Retracted Output

With a Z-score of -0.306, the institution shows a lower rate of retractions than the national average of -0.189. This reflects a prudent and rigorous approach to research oversight. The data suggests that the university's quality control mechanisms prior to publication are more robust than the national standard. Retractions can be complex, sometimes resulting from honest corrections, but a comparatively lower rate points towards a strong institutional integrity culture that successfully minimizes the risk of recurring malpractice or a lack of methodological rigor, reinforcing the reliability of its scientific output.

Rate of Institutional Self-Citation

The institution's Z-score for this indicator is 0.064 (medium risk), which represents a moderate deviation from the national average of -0.200 (low risk). This suggests the university is more sensitive to this risk factor than its peers. While a certain level of self-citation is natural and reflects the continuity of research lines, this elevated rate warrants attention. It could signal the formation of scientific 'echo chambers' where the institution's work is validated without sufficient external scrutiny. This dynamic poses a risk of endogamous impact inflation, where academic influence might be oversized by internal dynamics rather than by broader recognition from the global scientific community.

Rate of Output in Discontinued Journals

The institution records a Z-score of -0.495, a very low-risk value that is even more favorable than the already low national average of -0.450. This result indicates a state of total operational silence regarding this risk, demonstrating an exceptional level of due diligence in the selection of publication channels. A high proportion of output in such journals would constitute a critical alert, but Sorbonne Université's performance shows a strong commitment to channeling its scientific production through media that meet international ethical and quality standards, effectively avoiding reputational risks associated with predatory or low-quality practices.

Rate of Hyper-Authored Output

With a Z-score of 1.625, the institution shows a significant risk level in this area, amplifying a vulnerability that is already present in the national system (Z-score of 0.859). This is a critical point of attention. In certain disciplines like high-energy physics, extensive author lists are legitimate and structural. However, such a high score suggests that, beyond these "Big Science" contexts, there may be a pattern of author list inflation that dilutes individual accountability and transparency. This serves as a strong signal to review authorship practices to distinguish between necessary massive collaboration and potentially "honorary" or political authorship, which could compromise the integrity of the research record.

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

The institution's Z-score of 0.874 (medium risk) indicates a higher exposure to this risk compared to the national average of 0.512. This value points to a sustainability risk, suggesting that the university's overall scientific prestige may be significantly dependent on external partners rather than being fully structural. A wide positive gap, where global impact is high but the impact of institution-led research is comparatively low, invites reflection on whether its excellence metrics result from genuine internal capacity or from strategic positioning in collaborations where it does not exercise primary intellectual leadership. This dependency could challenge long-term research autonomy and innovation.

Rate of Hyperprolific Authors

The institution's Z-score of -0.195 is within the low-risk range but is higher than the national average of -0.654. This differential suggests an incipient vulnerability that warrants review before it potentially escalates. While high productivity can reflect leadership, extreme individual publication volumes can challenge the limits of meaningful intellectual contribution. The university's score, though not alarming, points to the need for monitoring to prevent potential imbalances between quantity and quality, such as coercive authorship or the assignment of authorship without real participation—dynamics that prioritize metrics over scientific integrity.

Rate of Output in Institutional Journals

With a Z-score of -0.268, the institution is in perfect alignment with the national average of -0.246, both of which are in the very low-risk category. This reflects a state of integrity synchrony, where the university's practices are fully consistent with a national environment of maximum scientific security in this regard. While in-house journals can be valuable, an over-reliance on them can raise conflicts of interest. The university's very low score demonstrates a clear commitment to seeking independent external peer review for its research, ensuring its work is validated through standard competitive channels and maximizing its global visibility.

Rate of Redundant Output

The institution's Z-score of 0.374 is nearly identical to the national average of 0.387, placing both at a medium-risk level. This alignment suggests a systemic pattern, where the observed risk level likely reflects shared practices or norms at a national level. This indicator alerts to the potential practice of 'salami slicing,' where a coherent study is fragmented into minimal publishable units to artificially inflate productivity. Such a practice can distort the scientific evidence and overburden the review system. The university's score indicates that, like its national peers, it could benefit from reinforcing policies that prioritize the publication of significant new knowledge over sheer volume.
