“Many parts, one timing. Coordination beats individual brilliance.”

# The Coordination Paradox A rule requiring all businesses to close on Sundays seems fair and pro-worker. But: - Supply chains depend on continuous operation - Manufacturers can't coordinate with suppliers who stay closed - Hospitals need Sunday deliveries; clinics face shortages - Workers lose overtime pay they relied on - Small shops can't compete with large competitors who stockpile The rule ignores **systemic interdependence**. When one part stops, the whole machine stutters. What seems individually beneficial breaks collective timing. Everyone agreed it was good in isolation, but failed to account for how their coordination actually functions.

“Set the terms before anyone else does. Everything after is a response.”

# The Goodheart's Law Trap A well-intentioned rule optimizes for a measurable proxy of the actual goal, but the proxy diverges from reality once everyone responds to it. **Example:** A hospital rule rewards fewer patient readmissions (good goal). Hospitals now discharge patients earlier, unprepared. Readmission rates drop on paper, but patients suffer worse outcomes overall. **Mechanism:** Everyone agrees the *stated goal* is good. But optimizing collectively for the *measurable target* creates perverse incentives. The rule succeeds at what it measures while failing at what actually matters—because we chose the wrong metric to enforce.
