“The political process is chaotic and often takes years to unfold, making it difficult to use traditional measures to evaluate the effectiveness of advocacy organizations. There are, however, unconventional methods one can use to evaluate advocacy organizations and make strategic investments in that arena”

A mechanism experiment is “an experiment that does not test a policy, but one which tests a causal mechanism that underlies a policy”

Randomized controlled trials are increasingly used to evaluate policies. How can we make these experiments as useful as possible for policy purposes? We argue greater use should be made of experiments that identify behavioral mechanisms that are central to clearly specified policy questions, what we call “mechanism experiments.” These types of experiments can be of great policy value even if the intervention that is tested (or its setting) does not correspond exactly to any realistic policy option.

RD comment: Well worth reading. Actually entertaining.
