This post is adapted from something I wrote in an email exchange with Jeffrey Friedman.
Consider two questions we can ask someone about policy knowledge.
1. Does an ordinary citizen know enough about policy area X so that you can say that things would be much better if an ordinary citizen were in charge of X?
2. Do experts know enough about policy area X so that you can say that things would be much better if they were in charge of X?
There are four possible answers: yes to both; no to both; yes to 1 but no to 2; no to 1 but yes to 2.
Yes to both is the progressive reformer quadrant. The claim is that we all know how to fix policy, but we have to overcome evil people by reforming the system.
Yes to 1 and no to 2 is the populist quadrant. Think of Trump supporters and policy area X is immigration. Or Bernie Sanders supporters who don’t believe the technocrats who say that we can’t afford free health care and free college for all.
Yes to 2 and no to 1 is the technocracy quadrant. You will find most mainstream economists here.
No to both is the skeptical quadrant. One example of a policy area in which many people can at least relate to the skeptical quadrant is “bringing peace between Israelis and Arabs.”
One thing to note is that you do not have to be in the same quadrant on every policy area. I am in the skeptical quadrant when it comes to most areas of economic policy, particularly macroeconomic management. Jeffrey and I are in the same quadrant, and perhaps not surprisingly we both champion exit over voice.
However, for me there are some exceptions. For example, I am relatively populist when it comes to breaking up the largest banks. I am in the technocracy quadrant when it comes to military operations or urban sanitation. I am not much in the progressive reformer quadrant. Perhaps the area where I come closest is housing finance policy. I see American housing finance policy as dominated by a conspiracy of interest groups, and I could see us being better off if policy were controlled by politically independent technocrats or even by ordinary citizens.
