@lain @sun and the "exposure" is always in the context of spending most of your time doing literally nothing, - waiting in halls, waiting to eat, waiting for class to start, waiting for the day to end, waiting to get permission to go pee, waiting for the bus, waiting for noise to die down, waiting for others to finish. What you learn can't be focused on a productive task but has to be squeezed into information that can easily tested. You can't have high standards because too many people won't meet them. You can't ask questions that get real answers because it'd mean too much discussion outside what's on the test. In any conflict the real crime was always against classroom order and, actually, you're worse than the instigator for 'escalating' and not letting the conflict die out as soon as the instigator was done abusing you.

There are benefits, but the point of comparison isn't "no benefits", it's the benefits you would've gotten in the alternative. The tall dude on the Angry Joe show, describing a movie that he got something out of, described the experience as like enjoying a "second harvest" - eating shit that has indigested food in it, so that you can get nutrition from those little bits of food.
