The paper provides an extensive interdisciplinary meta‐review of quantitative AI benchmarks by synthesizing critiques from approximately 100 studies spanning the last decade. It systematizes benchmark limitations by articulating a taxonomy of nine concerns that range from technical shortcomings to broader sociotechnical and economic issues.
The review first examines issues in data collection, annotation, and documentation. It highlights that benchmark datasets often inherit biases from their sources, suffer from spurious correlations, and are under-documented. This lack of provenance transparency leads to data contamination and unknown leakage, which in turn results in models that exploit dataset shortcuts rather than solving the intended tasks. The paper cites empirical evidence where performance on benchmarks is driven by exploitation of unintended signals rather than genuine understanding, a situation compounded by the recycling of data across domains.
Another major focus is the weak construct validity present in many benchmarks. The meta-review challenges the epistemological claims that quantitative tests are capable of capturing complex concepts such as fairness, ethics, or safety. It argues that benchmarks frequently make unsubstantiated normative claims and that their reductionist design fails to rigorously define what exactly is being measured. This critique is particularly concerning when benchmarks are used to evaluate high-impact capabilities or to assess compliance with regulatory measures, as it may lead to “safetywashing” where improvements in general capabilities are misrepresented as safety advancements.
The paper also situates benchmark issues within a broader sociocultural context. It emphasizes that benchmarks are not neutral artifacts but rather products of cultural, commercial, and competitive forces. The work discusses how dominant benchmarks—often concentrated in a few institutions—reify path dependencies and can narrow research incentives. This concentration exacerbates economic and competitive pressures, leading to an environment where SOTA-chasing and leaderboard competitions incentivize gaming the evaluation process. For example, the phenomenon of “sandbagging” is described, where models are intentionally underperformed on certain evaluations to mask potential safety risks.
Additional dimensions of the critique include:
- Narrow Benchmark Diversity and Scope: The review points out that many evaluation datasets focus predominately on text modalities, neglecting the increasingly multimodal nature of modern AI systems. This unidimensional focus limits the applicability of benchmark evaluations in real-world settings, which demand robustness across diverse inputs such as images, audio, and video.
- Competitive and Commercial Dynamics: There is considerable emphasis on how benchmarks have become intertwined with corporate marketing and hype. The review illustrates that benchmarks serve as a spectacle for technology companies to signal superiority in a highly competitive market, potentially sidelining ethical and safety considerations.
- Rigging, Gaming, and the Measure-Target Relationship: In light of Goodhart’s law, the authors argue that when benchmark scores become targets, they lose their effectiveness as metrics. The paper cites evidence that small changes in evaluation protocols—such as prompt engineering or statistical under-sampling—can drastically affect reported performance, thereby undermining the reliability of these measures.
- Dubious Community Vetting and Path Dependencies: The meta-review critiques how benchmarks gain unquestioned authority through community citation chains rather than objective validation. This path dependency further entrenches existing standards even when significant flaws or biases are known.
- Rapid AI Development and Benchmark Saturation: With the accelerating pace of AI development, many benchmarks have quickly become saturated or outdated. As models reach near-ceiling performance on established tests, the benchmarks fail to capture incremental improvements or emerging vulnerabilities.
- AI Complexity and Unknown Unknowns: Finally, the paper acknowledges fundamental epistemic limitations in anticipating emergent behaviors of complex AI systems, particularly in the context of AI safety. The potential for latent vulnerabilities that no current benchmark can capture is underscored as a critical area of concern.
Collectively, the critique points to the precariousness of relying solely on quantitative benchmarks for assessing AI performance, safety, and societal impact. The authors argue for a reassessment of evaluation methodologies and call for regulatory frameworks to incorporate multi-dimensional, transparent, and context-sensitive measures. The paper concludes by suggesting that future research must move toward “benchmarking the benchmarks” themselves, ensuring that evaluation practices evolve in step with the complexities of AI systems and the multifaceted risks they pose.
This detailed synthesis is valuable for researchers and policymakers alike, highlighting the urgent need to balance technical rigor with ethical and societal considerations in AI evaluation practices.
