I was talking to my doctor about treatment options for an ailment, and I said I wanted to approach it scientifically.  I wanted to take some sort of measurement before treatment, then a measurement after treatment to quantify the effect, instead of relying on how I feel before and after, which is subjective.  He said something that sort of blew my mind:  It might be better to measure the outcome subjectively if the outcome is subjective in nature.  In other words, if I could measure some quantity before and after and they showed no difference yet I felt better, the treatment is a success despite the measurement being inconclusive.  I feel like a more rigorous response would be that the process needs a better metric, but that's not the point.  I thought his response was pretty insightful coming from a profession that often operates from a sort of guess-and-check framework. #health
