Goodhart’s law is a sociological analogue of Heisenberg’s uncertainty principle in quantum mechanics. Measuring a system usually disturbs it. The more precise the measurement, and the shorter its timescale, the greater the energy of the disturbance and the greater the unpredictability of the outcome.
