Every metric, Matt Duffy argues, has something like a half-life. From the moment you adopt one, its bond with the thing it was meant to capture begins to erode. The crime rate drifts away from actual disorder; GDP keeps climbing while trust in institutions sits near record lows. The number holds steady while the world underneath it moves on.
Having once worked in performance metrics for public policy and research, the bit I keep chewing on is the reframing of the gap itself. When a measure stops tracking how people actually feel, the divergence isn't noise to be explained away — the divergence is the information. "Governance," Duffy writes, "is the practice of staying in contact with a moving reality through unreliable instruments."
It's a piece about legibility, really: the standing temptation to mistake the thing we can measure for the thing we care about, and to end up tending the artefact instead of the world.
