Challenge setup
Do not fall for Goodhart’s Law.
Doing so has destroyed lives, ruined careers, and cost people billions of dollars.
I’ll give you three famous examples of it to see if you can pick up on exactly what it is.
Don’t cheat. If you know already, just comment one of these.
Here it goes.
Example one: social ratings
There’s a Black Mirror episode where people can rate all of their human interactions.
It’s designed to increase social trust and incentivize good behavior.
This leads to a dystopia of fake niceness.
Example two: standardized testing
The No Child Left Behind Act of 2001 mandated standards-based education reform, where federal funding and penalties were tied directly to adequate yearly progress on standardized tests.
So schools started encouraging teachers to teach to the tests.
Newer studies show that the cost of education often went up by over $1,200 per student because of this.
And schools spent less time teaching non-tested subjects like art and science.
For shame.
Example three: social-media incentives
The internet right now.
When platforms reward creators for clicks, comments, and watch time, the best strategy can often become rage bait, exaggerated claims, and often flat-out lies.
Content engineered to make you furious enough to comment, or smug enough to share without verifying.
The creator profits, and the platforms become wretched hives of scum and villainy, and echo chambers.
We must be cautious.
And that was before AI.
Viewer challenge
These are all examples of Goodhart’s Law, but your team challenge is to generalize it in as succinct and clear a way as possible.
I’ll make a video responding to the best answer.
No cheating.
Additional Notes
The caption asks viewers not to cheat or read other comments before posting their own definition. It offers bonus points for another good example of the law in action.
