An attempt to answer the question of Synchronism vs. Asynchronism of Method Employment which states "The employment of new methods can be but is not necessarily a result of the acceptance of new theories."

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


The pre-scientonomic history of synchronism versus asynchronism of method employment originates in the thought of Larry Laudan. In his critique of Thomas Kuhn’s synchronicism of change in methods and theories, Laudan purports that change in method/methodology need not presuppose theory changes.2 For Laudan, anomalies can be addressed by methodological or ontological changes instead of theory modifications. Although for Kuhn “change is simultaneous rather than sequential,” Laudan provides many counterexamples depicting the opposite state of affairs.3p. 69 For instance, he cites the methodological shift in science from Bacon-Hume-Newton inductivism as evidence of asynchronism. The inductivism of the seventeenth century precluded the postulation of unobservable entities. However, between 1800 to 1860 acceptance of the existence of such entities became widespread, as evident in the writings of Whewell, Peirce, Helmholtz, Mach, Darwin, Hertz, and others.3pp. 81-82 According to Laudan, this methodological change across scientific domains cannot be linked to the theoretical revolutions of the time. This point evidences the independence of methodological change from the status of accepted theories.

Furthermore, additional proponents of the asynchronism of method employment include Dudley Shapere.

Question Answered

Asynchronism of Method Employment theorem (Barseghyan-2015) is an attempt to answer the following question: Which factors influence the process of method employment? Do new methods become accepted simultaneously with the acceptance of a theory?

See Synchronism vs. Asynchronism of Method Employment for more details.


The theorem states that the employment of a method is not necessarily simultaneous with the acceptance of a new theory. Being a direct logical consequence of the third law, the theorem highlights the fact that some methods are a result of the implementation of some abstract requirements of other methods. In this way, a new method can be devised as a means of resolving a particular creative gap, and subsequently become employed long after the acceptance of the theory that led to the employment of the abstract method.
