Which Characteristic Will NOT Strengthen the Validity of a Theory

Question

Which characteristic will NOT strengthen the validity of a theory?  
A) Repetitions of experiments
B) Increased observations
C) Time after the experiment
D) Faith in the experiment
E) Confirmation by many scientists

Accepted Answer

Faith in the experiment may be subjective and not based on empirical evidence, therefore it does not strengthen the validity of a theory. The other options (A, B, C, E) provide objective ways to strengthen the validity of a theory through repetition, increased observations, time for further data collection and analysis, and confirmation by other scientists.
