Tóm tắt	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.	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.
