| Resumo≠ | 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. | Multidimensional scaling maps objects described only by pairwise similarities or dissimilarities into a low-dimensional geometric space so that distances in that space reflect the original proximity structure as faithfully as possible. It is widely used to visualize the hidden structure of psychological, social, and behavioral data. |
