In the philosophy of science, the problem of "calibration circularity" poses a significant challenge to empiricist models of knowledge. Traditional empiricists argue that scientific instruments merely extend human sensory capabilities, objectively recording pre-existing natural phenomena. However, constructivist historians have highlighted how the initial calibration of novel measuring devices fundamentally relies on assumptions about the very phenomena being measured. For instance, the early standardization of the thermometer required researchers to assume that the boiling point of water was constant across different atmospheric conditions—a premise that could only be definitively verified after a reliable thermometer was widely accepted.
To resolve this apparent circularity, neo-empiricists propose the concept of "epistemic iteration." According to this view, initial instrument calibrations do not need to be flawlessly anchored in objective reality. Instead, scientists begin with a provisional standard—often grounded in everyday, prescientific experience—and use it to gather rough data. This data then allows for the refinement of the theoretical models governing the instrument, which in turn leads to a more precise calibration. Through successive cycles of measurement and theoretical adjustment, the instrument and the theory co-evolve toward stability. The neo-empiricists maintain that because this iterative process reliably converges on predictive success, the initial reliance on unverified premises does not invalidate the objective status of the final scientific discoveries.
Critics of the neo-empiricist approach, however, argue that predictive success is an insufficient metric for objective truth. They point out that a theoretical framework can reliably generate accurate predictions within a specific experimental context even if its foundational postulates are ontologically false. According to these critics, the convergence observed in epistemic iteration may merely reflect the scientific community's increasing adroitness at harmonizing an instrument's outputs with a preferred theoretical paradigm, rather than a genuine progressive alignment with an independent natural order. If the final calibration is evaluated solely by its internal consistency with the evolving theory, the entire process remains self-referential, sealing the scientific findings off from any independent empirical veto.
Which one of the following is an assumption upon which the neo-empiricists' defense of epistemic iteration depends?
- A scientific framework's capacity to reliably converge on predictive success cannot be wholly explained by the internal harmonization of its theories and instrumental outputs.Answer
- BAn instrument's outputs will inevitably align with a preferred theoretical paradigm if subjected to enough cycles of measurement and adjustment.
- CThe initial provisional standards drawn from everyday, prescientific experience provide a fundamentally more objective baseline than early theoretical models.
- DAny scientific methodology that relies on unverified initial premises will eventually achieve objective predictive success so long as it employs epistemic iteration.
- EThe problem of calibration circularity presents a significant philosophical challenge exclusively to empiricist models of knowledge.
