In this moment, Mayor Bill de Blasio is listening to Rev. Al Sharpton. However when a lateral jaw displacement is seen while listening to another speak (usually but not always directed away from the speaker as is exampled here) it's a strong signal of critical evaluation. De Blasio has anxiety about and disagrees significantly with at least some of what Sharpton is saying. While the listener may pretend (verbally) to agree (partially or entirely) with the speaker, his true emotions disagree - his body language betrays him. Very often he/she will NOT voice such a disagreement - yet they are thinking it. This disparity between what is expressed and what is thought is further amplified in this moment by the NYC Mayor biting his lip.
What can this body language display be often confused with?
