Focal points work through shared expectations of obviousness [causal]
And, if the Nash point appeals to us powerfully in the bargaining game, it must do so because we are confident that it appeals equally to our partner who in turn we believe to be aware that our views coincide. It must therefore appeal to us in the pure coordination game as a unique point that the partner will consider to be obviously obvious.
DEFINE: Explains how a Nash point becomes salient in coordination games — through recursive mutual awareness of its obviousness.
