Giving more relevance to the words being spoken rather than the -give away- gestures that say something quite different.
Follows needless brainstorming, highlight to read.
Actually the lying language hypothesis, by E. H. Sturtevant, resonates more strongly with me. In this view, language has emerged to hide selfish motives revealed by gestures.
In essense I find it a fail of education to understate insticts and overstate social behaviour. We are reptilians in brain cortex, that can't be changed. Insticts (including paying attention to gestures, not just words) should not be diminished, but rather filtered through culture.
If you bury your insticts, you are fighting yourself. If you, on the other hand, filter and enhance the more relevant ones (e.g. altruism; used in group competition) you are a rainessance man.
Currently many, if not most, people are really medieval personalities with advanced technology. Oscillating between unharnessed instincts, black & white, fight or flight mentalities; and mind-burning theory, culture above introspection.
Nothing can beat the combination of the two. Nothing. Look around you at the most successful people (less corruption), businessmen, athletes, scientists, artists, visionaires, writers, inventors, leaders and humanists. They use their complete self.
And even if you don't become a leader in your field you can still become "MVP in your own mind" (Michael Jordan).
I think the above statement is as powerful as it gets.
