Method Rejection theorem (Barseghyan-2015)

An attempt to answer the question of Mechanism of Method Rejection which states "A method ceases to be employed only when other methods that are incompatible with the method become employed."

Method Rejection theorem was formulated by Hakob Barseghyan in 2015.1 It is currently accepted by Scientonomy community as the best available theory on the subject.

History

Initially, the method rejection theorem was accepted as deducible from the conjunction of the first law for methods and Harder's zeroth law.

After the replacement of Harder's zeroth law with the compatibility corollary, suggested by Fraser and Sarwar, it became accepted that the method rejection theorem is a deductive consequence of the first law for theories and the compatibility corollary.2pp. 72-74

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.

Description

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 compatibility corollary, the elements of the scientific mosaic are compatible with each other at any moment of time. Thus, a method can only become rejected when it is replaced by an incompatible method or methods.1pp. 172-176 2pp. 72-74
