Cultural consensus theory for two-dimensional location judgments

Cultural consensus theory is a model-based approach for analyzing responses of informants when correct answers are unknown. The model provides aggregate estimates the latent knowledge at group level while accounting heterogeneity in informant competence and item difficulty. We develop new version cultural two-dimensional continuous judgments which obtained asking to locate set unknown sites on geographic map. fitted using hierarchical Bayesian modeling. A simulation study shows satisfactory parameter recovery realistic numbers items. also assess accuracy location by comparing against simply computing unweighted average informants’ judgments. that, due weighing inferred informants, more accurate than averaging. showed higher an empirical individuals judged 57 European cities maps.
