I kind of agree, only I don't at all mind if that learning process is done via in-fiction trial and error.It sounds weird, but I feel like you have to learn that "false information" is a particular kind of trope in the game your playing before you are attentive to these things.
Fair enough.So if I play with new players, or new players to a given system, I'll just 'metagame' comment on what happened in a scene in some way. But also I'm not exactly a thespian, so I'm likely not conveying a lot of things in any given npc interaction.
Some systems allow rolls to see through deception; even if the players haven't picked up on it there's nothing stopping a GM from secretly making such a roll on behalf of the PCs (this to cover over one's lack of thespianism, which despite my best attempts I too much of the time also suffer from) and if successful slipping in an aside to one or more of the players that something isn't sitting quite right here.
