Резюме	Rank-order elicitation asks each informant to place a set of items into a complete order on a single criterion — from most to least important, severe, preferred, or typical — so that the whole domain is captured in one ordinal judgment per person. Unlike paired comparison, which gathers many local two-item choices, ranking obtains the global order directly, trading some redundancy for speed. Aggregating the individual rankings produces a group ordering, while a concordance statistic measures how strongly the informants agree.	The triad test is an elicitation technique for measuring perceived similarity among the items of a cultural domain. Informants are shown items three at a time and asked to pick the one that is most different (or, equivalently, which two are most alike). Across many triads and many informants, the pattern of which items are repeatedly kept together yields a fine-grained similarity matrix that is analyzed with multidimensional scaling and clustering.
