“It’s probably Matt Mercer’s fault.”
And my reaction as always is "If I wanted to only play characters that can do what I can, I'd be LARPing." (Though that's probably even unfair to LARPing).
Edit: That was a little blithe and snarky on my part. But it still adds up to "If you're not good at judging liars, and/or the GM isn't good at properly displaying tells, good luck." Which seems at least as poor a play cycle as being dependent on die rolls.
And my response is that there are some situations you might like to present in a movie or book that just don't work in RPGs. One of those is gating an important plot point behind the requirement that the players either believe or disbelieve an NPC. If I have an NPC lie to the players and they know I'm lying because I'm a bad liar....that's ok. Or if I'm having the NPC tell the truth and the players think I'm lying...that's ok, too.
At the end of the day, they really just think they know; they don't actually know. And uncertainty is good.
And, for those who like simulation, that's how the world really works. We think we know somebody is lying or telling the truth, but we don't really know.
