Yes, but “intuition and traditional experience based human learning” is probably much less reliable in medicine than it is in barbering, so the latter isn't a good example in a discussion about the former.

The goal of barbering is to create haircuts that increase the attractiveness of the client to people besides the barber and the client.
A barber might think: "All my clients look really great", when in reality his haircuts reduce the attractiveness of the clients.

Surely, judging someone's attractiveness using your System 1 alone is less hard than judging someone's health using your System 1 alone, for most people in most situations?

A professional barber is likely to notice a lot of things about a haircut that the average person doesn't see. It could be that he creates haircuts that look impressive to other barbers but don't look good to the average person of the opposing sex who isn't a barber.

I do think that you can get a decent assessment of someone's backpain by asking them whether it has gotten better. Actually that's even how most scientific studies who measure pain do it. They let the person rate their pain subjectively and when the subjective rating gets better through the drug they see it as a win.

For a lot of serious health issues it's easy to see when a person gets better.

Most homeopathists spend more time interviewing their patients and getting a good understanding of their condition than the average mainstream doctor who takes 5 minutes per patient.
