How Can We Know “What Works” in public policy?

Evidence based on the experimental method relies on a degree of abstraction that makes it hard to apply whatever idea it supports in a particular setting.

This research may not be considered ‘rigorous’ by policy makers. Nevertheless, it is essential.
