Evidence-Based Policy

Nancy Cartwright

Oxford University Press

This chapter provides an overview of Part III of this volume. Even if a policy has been proven to work elsewhere, it will not work if the requisite support factors that are needed for it to operate cannot be secured, or if the right level on the ladder of abstraction have not been climbed, to identify the description under which the policy works widely enough to reach the desired situation. Identifying the support factors is called “horizontal search”; identifying the right level of abstraction and figuring out what that amounts to for the given situation is called “vertical search.” Some general strategies for engaging in these searches are presented.

Keywords:   policy, abstraction, support factors, horizontal search, vertical search
