Ok fine, you didn’t technically say that, but based on the way you present the two extremes it sounds like you’re asking why medical students don’t have autonomy and the answer is similar. One person has completed a degree with practical and theoretical training while MD/DO students are learning to transition from book smart to being useful in the hospital. That transition point varies for multiple people and I don’t think we should ask students do be making any unsupervised decisions at this point.
Again your point about glorified shadowing is valid in my opinion. Let me explain my thoughts about that a bit more. Looking at a medical school student/admin. All their focus is on students passing their MC exams and Step 1. After that, admin stops caring and students are thrown into a clinical setting where numerous entities are indirectly accountable for them and where learning is mostly passive. You can be aggressive and try to put a lot of effort in clinically but the way to do well in third year is to read and honor the shelves and be likable (not be competent) to receive evals. Summarized, there is no clinical competency assessed at all in medical school outside Step 2CS covering the bare minimum. Some students take it upon themselves to take more clinical responsibility than others but it’s completely self-directly. Then 4th year is a joke and the standards are to show up. Compare that to even nursing curriculum. Before interviewing patients, I sometimes see nursing rounds so I stop and watch in spite of myself. Their rounds on patients ware actually pretty educational from a practical standpoint. They have their head nurse sit and watch while the student starts present all the clinical information and are incredibly keyed into all the details. If they miss one detail, they’re marked down. It’s really a good thing to watch and something frankly some medical students who haven’t really clicked clinically need to see. If we miss even a critical thing like I/O on surgical patient or a foot exam on a new homeless diabetes admit, we’re just chided. Our grades don’t suffer and ultimately medical students are driven by grades. Once we get to residency, we are forced to pick up things very quickly as we get an active role. Until then, we are passive observers.
