Words and Pareto

Words constitute less than 20 percent of what is being communicated. Then why do words make or break? Why did Boyzone compose a song on words and that hit all of us in the nerve?

The reason is, words validate the body language and tonality, the other 80 percent. If no words are spoken, the (non) speaker can always deny the body language and tonality, because the listener does not have the evidence of words.

Remember Pareto Principle.
