Back to the original topic:

At jam sessions, which are events where most of the audience deliberately come to listen to music (although there may also be people who primarily just want to have a beer and don't care if a band is playing), I've noticed that people are simply impressed when musicians play together spontaneously and something beautiful emerges.

Yesterday, while I was getting a drink at the bar, someone suggested that the world would be a different place if people collaborated like this more often in "real life". I replied that there are already countless academic papers on jazz improvisation as a model for the workplace, society, and politics (always see them on academia.edu) but that probably nobody reads them (I don't read them, too, but I already have experienced the effect of musical collaboration on collaboration in everyday life). We came to the conclusion that more politicians should play in bands.

At jam sessions it's nice when the music is really grooving and people start dancing, sometimes even immediately as they enter the room.
