Past applications of Jasso's theory of justice evaluation, including several applied tests, generally support the theory but raise questions future applications should address. These include whether the theory might predict as well or better if the good in question is something other than income and if it would predict third-party evaluations as well or better than first-party evaluations. Moreover, the theory could be used for more demanding applications: interventions, which would involve changing the situation in order to affect justice evaluations. The theory itself suggests three means of effecting such interventions.
