A couple of quick things:

I find status in meetings interesting. Among the many ways it can be expressed are seating, interrupting others, smartphone use, and arrival and departure timing.

The class that most interested me at Princeton was social psychology. A major theme is that a significant part of behavior (apx 40%?) is situational vs rational. Think “Blink” or the horrible Stanford prisoner/jailor experiment. The particular circumstances of a meeting significantly govern behavior. By understanding the situational behavior, one can change the meeting circumstances to change the behavior.
