 Interestingly, White bills his account as a strong heuristic account. In making this claim he is claiming that the epistemic advantage of prediction would not be entirely erased for an observer who was completely aware of all relevant evidence and background knowledge possessed by the scientific community at the relevant point in time. This is because the degree to which theorizing is reliable depends upon principles of evidence assessment and causal relations (including the reliability of our perceptual faculties, accuracy of measuring instruments, etc.) that are not entirely “transparent” to  us.[12]  Insofar as fully informed scientists may not be fully convinced of just how reliable these principles and relations are, evidence that they lead to the endorsement of theories which are predictively successful continues to redound to their assessed reliability. Thus, White concludes, strong heuristic predictivism is vindicated (2003: 671–4).
