|Description=Sarwar and Fraser propose the ''law the theory demarcation'', which states that "If a theory satisfies the demarcation criteria of the method employed at the time, it becomes scientific; it if it does not, it remains unscientific; if assessment is inconclusive, the theory's status can become scientific, unscientific, or uncertain".[[CiteRef::Sarwar and Fraser (2018)]] The fundamental notion is that epistemic agenst agents employ mentods, which include the ''demarcation criteria '' used to differentiate, from the epistemic agent's perspective, propositions that are scientific from those that are not. A theory may become scientific when, after it is subjected to assessment by the demarcation criteria, it consclusively conclusively satisfies the criteria. Here, it would be impossible for this theory to be considered by the agent to be unscientific, pseudoscientific, or uncertain. The other mechanism via which a theory may become scientific occurs when, upon initial assessment, its status is not conclusively determinedonly inconclusively. Here, it is possible for the theory to then become scientific, turn unscientific, or remain uncertain. These are the two processes via which an unscientific theory may become scientific.

The process of via which a scientific theory becoing becomes unscientific also has two mechanisms. First, if the assessment outcome of the demarcation criteria consclusively conclusively deems the theory to be unscientific, then it cannot be considered scientific and its status cannot be uncertain. The other mechanism takes place when a scientific theory's assessment engenders the outcome inconclusive, which may lead to the theory being scientific, unscientific, or uncertain.

Among the four pathways, first two explain the possible mechanisms via which an unscientific theory may become scientific and the second two explain how a scientific theory may become unscientific. It may also be observed that in both cases the conclusive assessment outcomes isare, as it were, deterministic, whereas the inconclusive outcome outcomes in both cases is stachastic are stochastic in nature. All four, taken together, delineate the possible means via which an unscientific theory may become scientific and ''vice versa''.
