It’s intuitive that a patient who can spend an order of magnitude more time on his self care, and can self-articulate their symptoms, can occasionally self-diagnose better than a doctor. It’s not intuitive that a clinician with 4 years training and the same 30 minute window to diagnose you would do better than a physician with 12 years training.
The point is that it's easier for a service provider to spend 1-2 hours (or across multiple people) when they don't have to spend 12 years of training with high attrition rates. Both because it's more affordable, and because there's less scarcity.
