I got lots of helpful comments in my first post, so I'll try a second: I want to develop a list of criteria by which to evaluate a presidency. Coming up with criteria and metrics on the economy is pretty easy, but I'd like to ask for suggestions on proxies for evaluating:
- Racial relations;
- Gender equality;
- Impact on free trade / protectionism;
- Education;
- Any other significant factor that would determine whether a president is successful.
If I go to a homeopath and get better afterwards, I could use the metric of my health to measure that the homeopath is great at helping me.
While you might not reason that way in the domain of medicine and see the error if I frame that example this way, you want to reason this way in the political domain. You want to measure the quality of a presidency by looking at one run of the presidency.
Establishing causality is hard. Given that politics is the mind killer, this kind of poor reasoning often comes up in political discussions.
If you are generally looking for metrics, take a look at https://goodcountry.org/index/overall-rankings .
