Campbell's law is not simply a "social variant" of Goodhart's law. The two have a subtle but crucial difference. To paraphrase a DonaldTrumpism, Goodhart's law says "Sounds good, doesn't work". Whereas Campbell's law adds "Worse still, it'll certainly backfire", and makes that the focus. Incidentally, the other "law" alluded to in the text, also has a name: > The (Lance) Armstrong Principle: "If you push people to promise more than they can deliver, they’re motivated to cheat." A more general rephrasing: if you create / hold people accountable (e.g. by forcing a promise) to unreasonable expectations of performance that cannot be delivered there will be a motivation to cut corners, e.g. cheat.
