Moreover, conservation of energy means that in any physical system you can know what you don’t know. If you track the impact of two things, and measure their vectors afterwards, knowing their mass you can know (uncertainty aside) how much energy you haven’t accounted for. You know what should be there.

In economics, for example, you never have a situation that clear. You don’t know how much a factory ‘should’ be producing, or what the wage for a job ‘should’ be. It gets recursive very quickly.
