概要	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.	Free listing is a foundational elicitation technique in cognitive anthropology in which informants are asked to name, in any order, all the items they can think of that belong to a cultural domain — for example 'all the kinds of fruit' or 'all the things that can give you a cold.' Aggregating these lists reveals both the content of the domain (which items belong) and the salience of each item (how culturally central it is), inferred from how frequently and how early it is mentioned.
