Question Answered

Method Rejection theorem (Barseghyan-2015) is an attempt to answer the following question: When does an employed method become rejected?

See Mechanism of Method Rejection for more details.


According to the method rejection theorem, a method ceases to be employed only when other methods that are incompatible with it become employed. By the First Law for methods, an employed method will remain employed until it is replaced by other methods. By the Zeroth Law, the elements of the scientific mosaic must be compatible with one another. Thus, a method can only become rejected when it is replaced by an incompatible method or methods.1p. 172-176
