When my kids were maybe 6 and 4 we started playing One Night Ultimate Werewolf as a family. It very quickly became clear this was a bad choice: the oldest went from being terrible at lying (and so ~never doing it) to actually being pretty good, surprisingly quickly. As soon as we noticed this we stopped, and while she didn't go back to how she had been there was definitely much less lying and she didn't remain good at it.

Do you think she adopted her pokerface she learned it against you or was there another reason?

I think it's simpler than that: people get better at things with practice.

Werewolf isn't like poker where people typically try to conceal their emotions and leak nothing; instead you're trying to act like you're on the Villager team regardless of whether you actually are.

		Remember, being a good liar means you can sniff out a lie too. It's not a terrible skill to teach if it can be wielded for good. Maybe a mafia style game would be more suitable where both sides are played.
