Good Liar Detecting Tool

[Taly]

This is definitely for face-to-face conversation, but if:
1) Someone's knees are moved away from you (and they can help it)
2) They are not looking you in your eye (same condition as above)
3) Are deliberately muffling their speech ("")
4) Someone has a serious conversation with sunglasses on
5) Shielding their neck in some form, like with their chin

They are very likely to being lying, or are guarding an subject, object, or emotion.

But for mafia, I think this translates more into how inconsistent someone's posts are. If someone's tune within the game changes dramatically within a short period of time, I believe it more often than not, warrants suspicion.

Granted, any other example I can see this translating into mafia is subject to playstyle...
