Some regular old boring facts:
Liars are less-cooperative, make more negative statements & complaints, appear less friendly, and their faces appear less pleasant.[DePaulo et al. (2003)]

A Fun fact! Criminals are found to be the most accurate lie-detectors with an accuracy rate of 57%, closely followed by the Secret Service!

I know this list you shared are the ‘text book’ clues, but, I feel, the only way to catch a liar is by uncovering the truth. It usually does it on its own for me. I never have to be nosy or pushy; the truth simply falls into my lap. Most liars aren’t thorough; they lie to you because they think your gullible, so, in turn, they don’t cover their tracks well. If it doesn’t fall into your lap and you still don’t trust the person is telling you the truth, you have a choice… stay in contact with this person OR leave. It’s your choice who you interact with and for how long. Sometimes walking away is the best thing you can do for yourself.

Thank you for trying to enlighten us. I understand what your were trying to do here. But, I feel, perpetuating myths is as bad as telling lies. I hope a lesson is learned here.

This is nonsense as it very much depends upon a number of other factors that determine eye contact;
1) a person with low self esteem may well avoid eye contact
2) eye contact is a ‘cultural’ thing, many cultures see (sic) eye contact as threatening or offensive and so avoid eye contact
3) Someone who regards you as being superior to them (e.g. an employee, a pupil) may choose not to give eye contact.

Eye contact is more about control than communication. If you want the person you are talking to to give you eye contact, then you may well be seeking to control them (unknowingly, perhaps)
