> When a metric becomes a target it ceases to be a good metric as they say.

Nice to know the name for this — Goodhart's Law. And I think the core reason is that the cost to fake these metrics is far less than what they claim to represent. Stars, reviews, ratings, trading volumes — all cheap to manufacture, and only getting cheaper with AI.

I've been thinking about this a lot. These metrics are all just marketing signals to draw people's attention, trying to make some kind of deals. So the fix should be: make the cost of the signal match what it claims to represent. I'm obsessed with something called DUKI /djuːki/ (Decentralized Universal Kindness Income, a form of UBI) — the idea is that instead of stars or reviews, trust comes from deals pledging real money to the world for all as the deal happens. You can't fake that cheaply.

So the metric becomes the money itself — if you fake X amount, it costs you X, and the world will thank you by paying attention...

Imagine if GitHub let you back a star with real money — the more you put in, the more credible the star. And that money goes out as UBI for everyone. For attention makers, star anything you want, as much as you want. For attention takers, just follow the money to filter through all the noise that's so easy to manipulate...
