Ok, but if you are free to make whatever subsequent decision you want, what's the point of being told that you are persuaded, intimidated, deceived, etc.
Or, to elaborate, if the rules of the game determine that "you are persuaded" then the freedom to make whatever decision you want can and often does lead to dissonance. You are persuaded, and yet you refuse the offer? That makes no sense. Or it dilutes the meaning of "you are..." to such a degree that the statement is meaningless.
But if you tweak the description to say "the NPC is very persuasive" then there's no dissonance when followed by, "Yeah, but I'm still not buying it."
