Abstract
The paper explores the application of robustness analysis to the Hubble tension —the discrepancy between measurements of the Hubble constant from the cosmic distance ladder and the early universe. I argue that, depending on how robustness analysis is defined and applied, one might conclude that the tension stems either from unaccounted systematics or from new physics. Ultimately, I suggest that caution and a more refined robustness analysis are needed when comparing results from large-scale experiments and scientific collaborations in cosmology.
