However, if we have an intervention whose effect we expect to be roughly proportional to environmental differences, heritability tells us roughly how strong that intervention is. Similarly if we expect that our interventions will reduce environmental variance but not genetic variance, we can place an upper limit on how much we can reduce inequality.
