The anthropic principle in physics can be treated as a testable scientific proposition rather than a purely untestable metaphysical concept, as it yields specific entailments that can be evaluated against observed data.
The claim addresses the falsifiability of the anthropic principle in physics. Among the provided papers, [8] examines the methodological role and empirical boundaries of the anthropic principle in cosmology, while [9] explicitly argues and demonstrates that the anthropic principle is testable and capable of making evaluable predictions. No papers in the retrieved list refute this position. Therefore, the verdict is SUPPORTED.
