confirmability (plural confirmabilities)

1. The state or property of being capable of being confirmed.
   • 1968, G. Schlesinger, "Confirmability and Determinism," The Philosophical Quarterly, vol. 18, no. 70, p. 30,

     Nothing seems more natural than to approach confirmability via confirmation.

   • 2003, Frederik A. Muller, "Refutability Revamped: How Quantum Mechanics Saves the Phenomena," Erkenntnis, vol. 58, no. 2, p. 190,

     So the confirmability as well as the refutability of our theories (conditional if not categorical) are necessary conditions for the possibility of science.
