What Body Language IS What Body Language IS NOT

Movies and pop culture get this wrong all the time .  There are some biologically hardwired things we all do from birth and even these are impacted by culture and experience to create a single baseline for each individual like a body language fingerprint.

Baseline is everything

What is abnormal for one person is a mere habit for another. You must learn to discern if the toe tapping and fingernail clicking is just normal or something is causing a change.

Culture Matters

Everyone, barring disability, is born capable of the same movements but when a small child runs in the room using a gesture that is taboo, like the middle finger a parent stops it.  That is one impact of culture on body language and communication. There are many.

There are no absolutes

No.  Scratching the nose, covering the mouth or ears, and looking away are not meaningful alone. You need the baseline.

This is not mystical

This isn’t some magical power in fact it is downright mundane.  The skill set is about noting what a person normally does along with some biological basics and starting to observe and note baseline and deviation.

It is a life long process

I started In my twenties and every year and day since I  have learned something new not always from an “expert” either.

Your life creates a unique skill set

Because you have different experiences and knowledge from any other person how you apply the skills will be unique to YOU.  If you knew the same things I know now you would apply the skills through a different lens. ENJOY.
