A Note: There is high value in critically reviewing past literature, as it shapes present and future research directions. While scientific progress inevitably reflects the theoretical and technical limitations and priorities of its time—and therefore includes shortcomings—we must nonetheless acknowledge these constraints and invest some time to examine the existing literature to identify its strengths as well as weaknesses.
In questions of science, the authority of a thousand is not worth the humble reasoning of a single individual.
