Theory: what’s valued is what’s visible.
I understand this is almost exactly what Girard’s mimetic theory of desire is, but I arrived at it recently thinking about what types of behaviors are valued at different institutions.
Eloquence and general knowledge aren’t as valued here as traits as they were at my high school. I understand there are innumerable factors that could be influencing what I observe (not the least of which my bias and ignorance), but I think salience of behavior has explanatory power.
Consider a high school classroom. It has (hopefully) fewer than 30 kids, and, unless you whisper, not much can be said without others hearing it. Pedagogically, it’s also an interactive environment. Exchanges between students, and between teachers and students, are common and often about the class subject-matter. This means academic engagement is much more salient. When someone has an insight or a perspicuous point, they raise their hand, share, and everyone knows about it. Because clear thinking is (again, hopefully) rewarded in the classroom, students see there’s social value to being intellectually present during class.
Contrast this with a large college lecture. The most salient behavior your peers exhibit in this setting is note taking and silence. If they have a point to make or are wrestling with a valuable question, you will most likely never know about it. Even though students might engage in academic behavior after class and during office hours, this is almost never visible to the majority of students. They are most likely already out the door or believe the opportunity cost of going to office hours too high. The behavior isn’t visible, so it isn’t valued.
There is much more to thinking than the social value you (may) get from exhibiting it, but I feel like this principle explains some aspects large university culture. I am definitely not the first to think of this, but I believe the slogan has a grain of truth. Our own wants and desire (ontological status pending) are often so foreign to us. It’s much easier to look to the world for cues as to what we should value.
