An information-processing feasibility model is successful if it works, i.e. if it can simulate the phenomena to be described. Conversely, it can be refuted with a counter-example that shows the simulation to be incomplete or inadequate.
Ideally, the feasibility model should support hands-on interactive testing over the Web by readers/viewers, i.e. independent verification.
Feasibility studies use engineering rather than academic approaches to supporting and refuting models. Academic citations are generally not required to see whether a new type of airplane will fly. For a very complex model, with many variations in behaviour, statistics may be used, but generally not for simple models.
For Web-based simulation models, the models can be made interactive and thus allow some level of independent verification.
