I don’t know much about architecture, but I have dimly noticed some things.
At my gym, you go down a ramp to reach the exercise area. This makes you feel strong and powerful every time, which is encouraging.
At college there were two dining halls– one was better. It had long waits in line (a chance to talk with strangers,) was crowded (so you have to sit with people you haven’t met before,) dim lights (which help with inhibitions,) and circular tables instead of rectangular (which seemed to help too.)
At Grinnell College the dorms had lounges. Nobody used them. At University of Kentucky they were used. The difference was, at UK people had to pass through them during the normal course of the day.
