Effectiveness of intervention The effectiveness of intervention is widely debated, in part because the data suffers from selection bias; as Fortna has argued, peacekeepers select themselves into difficult cases. When controlling for this effect, Forta holds that peacekeeping is resoundingly successful in shortening wars. However, other scholars disagree. Knaus and Stewart are extremely skeptical as to the effectiveness of interventions, holding that they can only work when they are performed with extreme caution and sensitivity to context, a strategy they label 'principled incrementalism'. Few interventions, for them, have demonstrated such an approach. Other scholars offer more specific criticisms; Dube and Naidu, for instance, show that US military aid, a less conventional form of intervention, seems to be siphoned off to paramilitaries thus exacerbating violence. Weinstein holds more generally that interventions might disrupt processes of 'autonomous recovery' whereby civil war contributes to state-building.
