The expected value of any net impact assessment of any large scale social program is zero.

Bemerkungen
The Iron Law arises from the experience that few impact assessments of large scale2 social programs have found that the programs in question had any net impact. The law also means that, based on the evaluation efforts of the last twenty years, the best a priori estimate of the net impact assessment of any program is zero, i.e., that the program will have no effect.
