“It’s probably Matt Mercer’s fault.”
I think the more common case in the latter is at least "You don't think they're lying from what you can tell", and if you've never seen that, I have to gently suggest you've lived in a bit of a bubble here.
I probably have heard it expressed that way, but I haven't really thought about it because there's never been...that I can remember...a constraint placed on the player's choices as a result.
