talks about the importance of common knowledge
- > Moreover, mere mutual knowledge (i.e., both players knowing the same thing) is insufficient; for each player to be able to justify following the terms of a virtual bargain, the players must have common knowledge of the assumptions on which this bargain is based; that is, each knows these assumptions, knows that the other knows, knows that the other knows that they know, and so on indefinitely (e.g., 13, 14). For example, if both players believe that the table is heading for the living room but one erroneously believes that the other has a different goal, virtual bargaining is likely to fail.

"of course / obviously" is a powerful way to communicate something that you understand to be common knowledge to be self-evident to everyone in the conversation
- but it will produce frame shear or frame pressure if used in a context where that's not so
  - and potentially distrust or compartmentalization
- not just in a context where not everybody sees the thing as self-evident, but even in a context where everybody does but they don't have common knowledge
