Nonverbal communication can make a huge difference in how a question is received. Only 7 percent of what we say is conveyed through words, 38 percent through vocal element (tone), and the remainder through nonverbal indicators like eye contact, body posture, and so on. Though these exact numbers are often disputed, it’s generally agreed that body language and tone of voice matter in communication.
So it seems we should pay attention to them. Leaning your body in toward the other person, making eye contact, even touching someone on the arm if appropriate, can convey care when asking a question. Uncrossing arms and legs gives a sense of openness, while crossed arms can project hostility. Facial expression will be determined in part by the question being asked, but generally smiling and relaxing the face offers a countenance that encourages conversation.
