How do we know if we’re hearing the truth from someone. It has very to do with the actual content they say, that gives them away. The theory goes;
55% is Body Language (subliminal micro actions people don’t even know they are doing…. So can’t help)
38% voice (digitals including pitch, speed, tone & volume. All uncontrollable)
7% content

It really is not what they say…. It’s not how they say it.
Like it or not , you’re subconscious will always tell the truth, no matter how you try.
