What you see here is a brief overview of my recent thoughts about the field of evaluation and the future of AEA. See the PDF for a more fleshed out explanation. Fair warning, it runs to 2,500 words. I am not advocating change, I’m only advocating that we recognize where we are and where we are going, and that we contemplate the consequences. AEA_Evaluation_Evolutionary_Path_Long
The challenge of contending points of view in a representative democracy goes back to the founding of the Republic. James Madison saw the polity as a collection of “factions” and believed that a stable democracy required a diversity of contending factions.
One way to think about the purpose of evaluation is to see it as an honest broker to which those factions can turn. This is not to say that any given evaluation can be, or should be, “objective”. Supporters of one or another point of view will inevitably find the results of any single evaluation wanting.
The question is whether over time, and across evaluations, it matters whether we are seen as taking sides. That perception has consequences for evaluation use, and I can see how outsiders would get the impression that we do take sides. If they do, they will shop elsewhere for evaluation information.
I’m not sure if we can or should change. But I do not think we should continue on our path without awareness of where that path is taking us.
Evaluation Uncertainty 
As an AEA member, I personally hope that AEA continues to advance its values that you mentioned. Evaluation needs those values to fulfill its potential for advancing the public good. Thanks.
