Answer:
a. falsifiability
Explanation:
Falsifiability is the character of scientific theories which are always likely to be refuted by experience but which can never be definitively confirmed or corroborated. In other words, we can state that the falsifiability criterion is the process of confronting a theory with observation data in an attempt to prove its falsity. John's statements about the super bowl cannot be refuted, so we can conclude that John violates the falsifiability principle.
