1) Touching the Face: Not only is body language the least reliable channel of predicting if someone is lying, manipulators and pacifiers are something a lot of people already know about – and therefore – one of the first things a liar may try not to do.
2) Making Eye Contact: Studies have shown people who lie actually make more eye contact (than their usual baseline), as they want to see if you believe them or not.
3) Moving Uncomfortably & Fidgeting: You might be naturally “fidgety” or it could indicate you’re experiencing elevated stress – which still doesn’t “mean” you’re lying – just that you are experiencing stress.
4) Pausing & Speech Disfluencies: Without knowing an individual’s baseline and being aware of the context, people can mistake these for signs of deceit. Are they having to think hard, or are they under stress? This alone is not enough.
5) Poor Memory: If someone can’t recall an event, it doesn’t mean they’re lying. People can forget things – what to look out for is how convenient it may be to forget details.
