>qualitative and inherently unmeasurable. Qualitative doesn't imply unmeasurable. If something is unmeasurable, there is no way to tell if it's changed. If you can tell if something has changed, and you have no feelings about it, you can measure it, but not optimize it, because you can't force it towards your preference. If you can tell if something has changed, and you know how you feel about it, you can always just say "I feel better about this since last time" or "I feel worse about this since last time." There you go, you can graph how you think of the thing over time, and steadily increase how much you like it.
