I argued that the signal-theoretic[1] analysis of meaning (which is the most common Bayesian analysis of communication) fails to adequately define lying, and fails to offer any distinction between denotation and connotation or literal content vs conversational implicature.
In case you haven’t come accross this, here are twopapers on lying by the founders of the modern economics literature on communication. I’ve only skimmed your discussion but if this is relevant, here’s a great non-technical discussion of lying in that framework. A common thread in these discussions is that the apparent “no-lying” implication of the analysis of language in the Lewis-Skyrms/Crawford-Sobel signalling tradition relies importantly on common knowledge of rationality and, implicitly, on common knowledge of the game being played, i.e. of the available actions and all the players’ preferences.
