摘要	The paired comparison method is a systematic elicitation technique in which informants are shown every possible pair of items from a set and asked, for each pair, which member better fits a single criterion — which is sweeter, more dangerous, more prestigious, or more similar to a reference. Because every item is judged against every other item, the procedure forces fine, transitive discriminations that a one-shot ranking would blur. Aggregating the pairwise verdicts across informants yields a dominance or proximity matrix from which a stable rank order or an interval scale can be recovered.	Successive pile sorting is an extension of the single-level pile sort in which informants first divide a set of items into a few broad piles and then repeatedly subdivide each pile into finer groupings (or, in the lumping variant, repeatedly merge piles into coarser ones). Recording the level at which any two items first become separated yields a graded similarity measure that captures the hierarchical structure of a cultural domain, not just a single flat partition.
