Dress, posture, and setting as additive factors in subjective probabilities of rape

Subjects indicated the likelihood that a female, photographed in eight situations, would be raped. The situations were created by the Cartesian product of her dress (seductive/nonseductive), posture (aggressive/nonaggressive), and setting (inside/outside). The three variables combined additively with the highest subjective probability of rape associated with the seductive/nonaggressive/outside condition.
