Ahh, sorry we’re talking past one another then because I hadn’t twigged you were talking about getting better at learning because that’s not what I meant with my initial post! Although I can see why you took that from it.

I do like that meta observation though that not only do people get better at prediction through learning they can also get better at the rate at which they improve their predictions.

It’s careless of me to say it’s a definition of intelligence, but I do think that property of being able to improve how you learn and how quickly you learn (especially in response to adversaries doing the same thing) is a clear indicator of intelligence and there’s a good argument that that’s why we developed intelligence. These aren’t my ideas either, I’m just parroting what I recently read in the book “What is Intelligence” by Blaise Aguera y Arcas.
