Since 2017, I’ve spent loads of time thinking about group coordination. “Common Knowledge” as a concept has been an important cornerstone of that thought.
I think I had known the general concept of common know prior to this post, but:
a) This is the first post that I read, where the explicit formalization of the problem helped me see exactly how the gears worked. (Previously, a lot of formalization-posts had been somewhat above my math or game theory background, and so I had to make due with some simplifications and analogies).
b) Ironically, well, I wasn’t sure the rationalsphere had common knowledge of common knowledge. This seems a particularly important post for lots of people to have read, and to know each other has read, to improve our ability to coordinate with each other. (This post also feeds into general explanation of why it’s useful to have posts that everyone-knows-everyone-knows[etc] we’ve all read)
At the time, this was concretely helping me further understand the concepts behind Inadequate Equilibria, and since then have been useful to my understanding of Stag Hunts and other phenomena.
