A few months ago, Derek Thompson wrote about the night he left his Oura ring on the nightstand. Out late with an old friend, too much mezcal, a full night of sub-optimal data ungathered. “Thank God for that,” he wrote. “We lived.”
The philosopher C. Thi Nguyen put the problem in two sentences: “Metrics are useful because they compress information. They are dangerous because they compress information.”
Same property. Two directions.
Compression is what makes a metric useful. You don’t need to understand heart rate variability — you just watch your Readiness score drop after wine, and you change your behaviour. But given enough time, the compressed version becomes easier to manage than the original. You stop asking how you actually feel. You check the score. The map stops representing the territory and starts replacing it.
Goodhart’s Law is usually taught as a management curiosity: when a measure becomes a target, it ceases to be a good measure. The stranger version is what happens next. The territory quietly disappears, and everyone carries on managing the map — because the map can be measured, ranked and shown to others, and the territory is messy, invisible and slow.
The diagnostic question is always the same: does this system help you do something you couldn’t otherwise do — or does it produce a representation of having done it?
Your health dashboard is not your health.
Your knowledge vault is not your thinking.
Your productivity system is not your output.
One unmeasured Thursday was the best health decision Thompson made that month. His ring never knew. He did, because the ring could not measure one of the most important health levers – human connection.
