More like we know that people can always find an obscure enough number to support what they want to do. There's a lot of value in having simple metrics that are hard to game.
Inflation is easily gamed by manipulating the basket of goods used to determine it.
Unemployment can be manipulated by only including people who „actively search” for the job, and tweaking the definition of „actively”, counting part timers.
Well sure, but the more complex your measurements are the worse you make it. Rather than looking for more nuance, we should look for stricter approaches to avoid those issues.
