Changes

The [[The Third Law|third law]] allows for two distinct scenarios of method employment. A [[Method|method]] may become employed because it follows strictly from accepted [[Theory|theories]] or employed methods, or it may the abstract requirements of some other employed method. This second scenario allows for creative ingenuity and depends on the technology of the times, therefore it may be fulfilled in many ways and allows underdeterminism[[CiteRef::Barseghyan (2015)|p. 198]].

The process of [[Theory Acceptance|theory assessment]] under the TSC is underdetermined for two reasons. First, only [[Theory|theories]] that are constructed are available for assessment. Whether or not a theory is ever constructed is, at least partly a matter of creativity, and is therefore outside the scope of the TSC. Second, it is at least theoretically possible that a process of theory assessment will be inconclusive. This might be because the employed method of the time is vague, or because it involves multiple criteria, only some of which have been met[[CiteRef::Barseghyan (2015)| p. 199-200]].

Taken together the theorem of underdetermined method change and the theorem of underdetermined theory change imply that scientific change is not a strictly deterministic process[[CiteRef::Barseghyan (2015)| p. 201-202]].
