概要	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.	The cultural consensus model is a latent-structure measurement framework that estimates the culturally shared answers to a set of questions and, simultaneously, how much each informant knows, without the researcher knowing the correct answers in advance. Introduced by Romney, Weller and Batchelder in 1986, it treats agreement among informants as evidence of shared knowledge and uses a factor-analytic (or, in modern variants, Bayesian) decomposition to recover both a single 'answer key' and an informant-specific competence score.
