Heather Lanthorn cites Gary King et al. on the need for ‘politically robust’ experimental designs for public policy evaluation:
scholars need to remember that responsive political behavior by political elites is an integral and essential feature of democratic political systems and should not be treated with disdain or as an inconvenience. instead, the reality of democratic politics needs to be built into evaluation designs from the start — or else researchers risk their plans being doomed to an unpleasant demise. thus, although not always fully recognized, all public policy evaluations are projects in both political science and political science.
The point here is that what pleases journal reviewers is seldom useful for policymakers.
