People lie, evade, omit, or exaggerate all the time. For example, talking about things that make them uncomfortable. It’s one of those unconscious things that makes societies work.
This isn’t unconscious for me. I see everything and analyze it logically.
Detecting misdirection is fairly easy for me. When someone is actively lying, they are generally trying present specific body language and inflection.
What happens is they miss something and I see the mismatch between the fake and real signals. It’s very similar to reading a polygraph.
This isn’t a unique ability, most people have it and it manifests as a gut feeling. I’m neurodivergent and I’m able to give more than a gut feeling. I can usually point to what I’m seeing and explain it.
All that said, I haven’t found any general “tells” for good lairs. It’s an art, not a science. It’s one reason polygraphs aren’t allow in court and I don’t use this ability to make snap judgements. :)
