alt Hacker NewsI believe the author was arguing that “calibration” is also rational but it cannot be transmitted. You cannot learn it from reading or following a framework. Books and frameworks are too lossy. The author cited the example of doctors in their residency as an example of this second mode of learning. They are learning from hands on experience what other doctors had also learned before. With residency there are others who oversee the residents.
You're arguing against something I wasn't trying to imply.
Choosing a good abstract dichotomy is hard (mine is also faulty, as you have noted).
They chose "instruction" versus "calibration" which I feel is a terrible splitting plane (muddying whatever they are trying to articulate).
I have been fascinated listening to a smart nursing friend of mine explain some of the intuitions they learnt through observation (not explicitly taught). I believe they had an outlier skill for noticing patterns. They might have been able to teach the patterns they saw, but they probably couldn't teach the skill of discovering patterns ≈intelligence.
