What Austin says here is consistent with the operation of the capacities being reliable in some circumstances, and with their reliable operation being such as to give rise to knowledge.
The theory of fluids can be used to emphasize this point: whether we express that theory in Eulerian or Lagrangian form will deeply affect what, in practice, we can calculate and how; it will affect what idealizations, approximations, and calculational techniques will be effective and reliable in which circumstances.
And it is open to him to hold that if the exercise of judgmental capacities is to give rise to knowledge, those capacities must be reliable in the circumstances in which they are exercised and given the way they are exercised on that occasion (e.g., carefully).
Even under the best circumstances, reliable collateral vessel counting is difficult to perform.
CRC risk prediction using genetic data may be more reliable under some circumstances than reliance on intermediate biomarkers.
Serological assays based on IgM and IgG detection provide a method for identifying HCMV infection, but IgM results are not reliable in certain circumstances.
For instance, it is challenging to make reliable predictions in circumstances that are necessarily highly stochastic due, say, to the small population sizes of invasive propagules, or the haphazard and sporadic nature of inadvertent introductions.
Procedures that ensure reliable performance under these circumstances are inherently constrained.
The Russian aviation regulator, Rosaviatsia, urged caution while the cause of the crash was being investigated, saying: "Until there is reliable evidence about the circumstances of what happened, there is no sense in putting forward and discussing any versions".
In our studies, we have observed that industry-based or product-versus-service-based categorization schemes almost never constitute a useful foundation for reliable theory because the circumstances that make a theory fail or succeed rarely coincide with industry boundaries.
In particular: There is a constraint of reliable feedstock supply under circumstances that achieve low agricultural yields today.
