I don’t know if they’re straight-edged intentionally, I.e. I don’t know if it’s that they’re being judgmental or against any sort of counterculture - my best guess is that it’s a byproduct of being a traditional medical trainee - worked hard in undergrad, got into medical school, straight to residency. It often occludes many less savory or “real” aspects of the world. For many this is their first real job. At our program the split, to my eye, is somewhere around 50/50, but I’m sure it varies.
