概要	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.	Pile sorting is an elicitation technique in which informants are handed a set of cards — one per item in a cultural domain — and asked to group them into piles of items that 'go together.' By recording which items each person places in the same pile and aggregating across many informants, the researcher builds a similarity matrix that reveals how the culture organizes the domain, which is then visualized with multidimensional scaling and clustering.
