|Description=[[The Second Law|The second law]] specifies that, in order to become accepted, a theory is assessed by the method employed at the time.[[CiteRef::Barseghyan (2015)|pp. 129-132]] Barseghyan envisioned three possible distinct outcomes for theory assessment: accept, not accept, and inconclusive.[[CiteRef::Barseghyan (2015)|p. 199]] Are there really cases where the assessment of a theory is ''conclusive'', or is there always some degree of ''inconclusiveness'' involved? If there are necessary cases, is it possible for us as historians to show decisively that a theory assessment had a conclusive outcome, e.g. to show that it was accepted after having conclusively satisfied the requirements of the employed method rather than accepted after an assessment that involved some degree of inconclusiveness? We can ask the same question with regard to mosaic splits: are [[Necessary Mosaic Split theorem (Barseghyan-2015)|necessary splits]] actually possible, or are all mosaic splits the result of inconclusive assessment? And if they are possible, can we ever as historians detect them?

While the question of scientific underdeterminism is not identical to the question of conclusive theory assessment, the questions are related. If theory selection were a deterministic process, then there would be no possibility that any theory selection process could result in an inconclusive assessment. Only if theory selection were underdetermined by the empirical evidence, would an inconclusive theory assessment even be possible.

|History=Patton, Overgaard, and Barseghyan have proposed a modified [[The Second Law (Patton-Overgaard-Barseghyan-2017)|Second Law]] of Scientific Change that they feel better accommodates the possibility of an inconclusive theory assessment and better explains how mosaic splits occur. [[CiteRef::Patton, Overgaard, and Barseghyan (2017)]] Their modified version of the Second Law has not been accepted yet by the scientonomy community.
