According to the confluence theory (D. Trafimow, 2009), there is a general tendency of associated mental elements to become compatible with each other. It is possible to derive a reversibility principle from this theory; effects that have been shown to go in 1 direction also can be shown to go in the other direction. Two experiments applied these ideas to just-world phenomena. In Experiment 1, the authors replicated traditional just-world effects but also demonstrated that they occur in the reverse direction. In Experiment 2, the authors extend the notion of compatibility by showing that the value participants assigned to luck is influenced by the assumed goodness or badness of the person involved. The authors also obtained a "contagion" effect whereby a person associated with the target person was tainted by the target person's goodness or badness.
