2017 Klein Lecture: The Science of Using Science: Toward an Understanding of The Threats To Scalability

Abstract

Policymakers are increasingly facing the challenge of scaling empirical insights. This study provides a theoretical lens into the science of how to use science. Through a simple model, we highlight three elements of the scale-up problem: (1) when does evidence become actionable; (2) properties of the population; and (3) properties of the situation. Until these three areas are fully understood, the threats to scalability will render any scaling exercise as particularly vulnerable. Accordingly, our work represents a call for more policy-based evidence, whereby the nature and extent of the various threats to scalability are explored in the original research program. Show more
