Evidence for log odds as an inherent representation of uncertainty. Participants saw pairs of photos of faces. One group of participants rated the similarity between the two faces in each pair. A second group judged whether the two persons on each pair were related or not. (A) The similarity rating of two children faces is a linear transformation of the log odds of the two children being judged to be related. Reproduced from Maloney and Dal Martello (2006). (B) The similarity rating of two adult faces is a linear transformation of the log odds of the two adults being judged to be related. Reproduced from DeBruine et al. (2009). R2 denotes the proportion of variance accounted by the linear fit. See text for implications.
