#Goodhart's law: When a #measure becomes a target, it ceases to be a good measure.

@landley

My government's favourite trick for gaming inflation numbers (also practiced by many other nations) is omitting "highly volatile" elements from the calculations. Specifically, food and energy.

Because the average person spends basically none of their money on those two items, right? And the prices of those shoot up crazily, but their prices also drop like a stone the next month, making the consumer come out even, right?

Goodhart's Law, etc, etc.

"Well, sure, all our sandwiches now come with shit. Shit is a very popular topping with our customers, so we thought we'd make it easy for all of you to get what you want. We determined it was too confusing for customers if some sandwiches came with shit, and some didn't, so we simplified our menu to make sure you could find exactly what you need. No, you can't order a sandwich 'but hold the shit'. After all, if you're that dead-set against eating shit, you can just order your sandwich and then eat around the shit."

Goodhart's Law is one of those ideas, once you learn it, you find it everywhere. I rewrote this post in order to read it for the podcast (so it flowed more) and it turned out so much better that I've updated the post. #MentalModels #politics #philosophy #GameTheory #GreatIdeas #Goodhart #Economics

GOODHART'S LAW

Bide batez, Goodharten legearen berri izan dut testuaren bidez: "neurgailu bat helburu bilakatzen denean, neurgailu ona izateari uzten dio"

https://en.wikipedia.org/wiki/Goodhart%27s_law

"En 1920, voyant les cas de peste se multiplier, la Ville de Paris a annoncé qu’elle verserait une prime à toute personne qui lui présenterait un cadavre de rat. Entre septembre 1920 et juillet 1921, 500 935 rats ont été tués. Six mois plus tard, les autorités changeaient leur fusil d’épaule en voyant que des gens avaient commencé à élever des rats pour revendre leur cadavre."

Un exemple de la loi de #Goodhart ?
