Yeah....I vehemently disagree with this viewpoint. Scribing is of course useful, and it will help you get a better idea of what a doctor actually does on a day to day basis, but you are ultimately just a privileged observer, sheltered by the attendant doctors. You don't really contribute in any significant way to the care of the patient, you are not integrated into the work environment, and your responsibilities are basically non-existent. Rather, the whole experience is centered around optimizing your own experience (eg. gaining a few anecdotes for an interview, adding another bullet point to your resume). It's incredibly self-absorbed, and really, what can you learn in 4o hours of scribing that won't be easily learned in 2 during medical school?
Working in a medical environment on the other hand forces you to acknowledge your own ignorance. You don't get to hang on to the doctor's coat tails, flitting around from room to room as if you've earned some sort of respect just because you've taken rudimentary science courses. Rather, you get your hands dirty. You have to actually talk to the patients as equals; they'll tell you things (both good and bad) that they wouldn't in the presence of a doctor. You learn to respect nurses, phlebotomists, janitors, lab techs, etc. It is at once a belittling experience, and an incredibly transformative one. The delusion that as a pre-med student, you have some inherent quality or educational esteem, is completely dispelled, and you learn to appreciate the entire medical team. Not just the doctors.
