People who cut themselves with knives often have scar tissue that reflects that. Self-cutting often means that the person had depression in the past.
Some people peel skin of their fingers to deal with nervousness and that leaves marks. This habit can go in hand in hand with high anxiety/OCD.
I am very interested in more sophisticated rules relying on gestures, posture, gait, or eye movement to conclude interesting facts, assuming they are reliable.
Your ability to identify specific gait patterns in other people depends a lot on your ability to feel distinctions in how you move in your own body. If you don’t have trained body awareness I would expect most sophisticated rules to lead you astray.
There’s some tensing up in healthy people when they tell a lie. Given that there are plenty of reasons why someone might tense up that’s no good way to diagnose whether someone lies, but if you see someone who can lie without tensing up at all that is a sign of sociopathy. Sociopaths also have a lower startle response than healthy people.
