We provide a correction to Davis-Stober et al. (2015) “The algebraic structure of individual preferences”. In the original paper, the Bayes factors for the Weak Order Mixture Model (WOMM) against an unconstrained, encompassing model were calculated using an under-estimate of the Euclidean volume occupied by WOMM. The correct estimate of the volume used in the Bayes factor calculations should be .000453, not .0000453, as was used in the original analysis. This computational error caused the distribution of WOMM classifications to be slightly too high in the original paper. We provide updated model comparison tables. The main empirical results of the original paper still hold.
