In the rapidly evolving field of applied artificial intelligence (AI) for materials science, benchmarking serves as a cornerstone for evaluating model performance and guiding research trajectories. However, this paper advances a conceptual critique that unveils the inherent illusions embedded within conventional performance comparisons, which often obscure the nuanced realities of materials discovery and prediction. By synthesizing recent literature, we highlight how benchmarking practices can perpetuate misconceptions about model efficacy, generalizability, and alignment with real-world materials challenges. The critique centers on the interaction dynamics among data representations, evaluation metrics, and contextual factors, revealing feedback structures that amplify epistemic distortions. We propose a novel conceptual framework that reinterprets benchmarking as a multi-layered system of steering logics, in which trade-offs among precision, robustness, and interpretability shape the interpretive landscape of AI-driven insights into materials. This framework emphasizes systems-level insights into how illusory superiority emerges from mismatched expectations and overlooked interdependencies. Through analytical implications, we explore how recalibrating these dynamics could foster more transparent and ethically grounded performance assessments. Ultimately, the paper advocates for an integrative approach that prioritizes conceptual interpretations over superficial metrics, offering epistemic reasoning to navigate the complexities of materials AI without succumbing to benchmarking illusions. This conceptual reevaluation has the potential to refine the field's theoretical underpinnings, promoting advancements that are both innovative and reliable.

In the rapidly evolving field of computational and data-driven materials engineering, machine learning models are increasingly deployed for property prediction, inverse design, and autonomous discovery. However, the integrity of these models hinges on the quality of training datasets, which often embed subtle biases arising from construction methodologies. This manuscript explores the conceptual underpinnings of dataset construction bias in materials AI evaluation, framing it as an epistemic challenge that distorts benchmarking outcomes and impedes genuine materials discovery. We introduce the Dataset Integrity Cascade (DIC) framework, a layered conceptual model that maps data curation processes to inference distortions, incorporating feedback mechanisms to reveal how biases propagate through representation learning, model training, and validation pipelines. By synthesizing recent advances in materials informatics, graph neural networks, and uncertainty quantification, the framework highlights systemic trade-offs between dataset scale and representational fidelity. Implications extend to high-throughput computation, closed-loop experimentation, and foundation models for science, suggesting pathways for more robust computational steering in materials design. This work underscores the need for integrative approaches that align dataset architectures with the inherent complexities of materials systems, fostering epistemically sound innovation without empirical validation.
