Another aspect of body language considered to be universal is the shoulder-shrug. It is usually used to indicate a listener does not understand what a speaker is saying.
According to the Centre for Non-Verbal Studies, the shoulder-shrug is a gesture that lifts, raises, or flexes-forward one or both shoulders in response: a. to another person’s statement, question, or physical presence; or b. to one’s own inner thoughts, feelings, and moods. It is also a universal sign of resignation, uncertainty, and submissiveness.
