How evidence-based policymaking helps and hinders policy conflict

Abstract

A popular explanation for governments’ persistent enthusiasm for evidence-based policymaking (EBPM) is its expected capacity to solve policy conflict. However, research is divided on whether or not EBPM actually has a positive impact on conflict. On the one hand, EBPM is said to introduce a set of principles that helps overcome political differences. Simultaneously, EBPM has been criticised for narrowing the space for democratic debate, fuelling the very conflict it is trying to prevent. This article explores how EBPM structures policy conflict by studying the example of Environmental Impact Assessments (EIAs) in policy processes through reconstructive interviews and ethnographic observations. It argues that, although EBPM channels conflict in a way that prompts engagement from stakeholders, it also escalates conflict by misrepresenting the nature of policy processes. As such, the findings suggest that managing process participants’ expectations about what evidence is and can do is key in fostering productive policy conflict.
