These don't work for very good liars. They know all these tricks, often intuitively, and purposefully avoid them. The only strategy that works is listening to your gut and extending trust slowly. Keeping up a ruse is tiring and the more time you give them, the more chance they have to make a mistake. Combine that with listening to the brain in your gut that has evolved for millions of years to sense danger. In the early stages, the mistakes are often subtle and you will usually only get a feeling that something is "off".

On the contrary, relying on your gut is unreliable because they know how to play your gut, if they're experienced liars. They have the same tools as you when it comes to "sensing danger".

But what this article focuses on, is that it's hard to be consistent when you're lying. That's my experience from social deduction type games too: don't focus on gut or "tells", focus on the "world they're building" in these games' in-speak, and how well it holds up compared to other worlds.
