We are communicating constantly. Because our communications go beyond what we say, write, and text, in my book, The Art of Communication: A Librarians Guide for Successful Leadership, Collaboration, and Advocacy (Libraries Unlimited, 2022), I devote a whole chapter to the “Silent Messages You Send.” We can never forget that our bodies speak for us as well.

Our posture, the position of our arms and legs, and the full range of our facial expressions are all conveying a message. Most of the time, the non-verbal message is, hopefully, aligned with what we are saying. Sometimes it isn’t. When we are uncertain, we are prone to sending mixed messages which can push our audience away and inhibit trust.

Those mixed messages are more likely to occur when we are giving a presentation. Whether we are teaching our colleagues about a new tech app or speaking at a state or national conference, we are nervous. We might have some stage fright. The Imposter Syndrome kicks in. And now you are facing your audience. If your body is apt to be telling your audience how uncertain you are, you won’t be able to get your message across as clearly as you want. This is where practicing in front of a mirror or even taking a video can help. Be honest about what you see and soon you’ll be more comfortable.

One of the things that can benefit your ability to connect with whomever you’re speaking to (whether an individual or a group) is supporting gestures that correspond with what you are saying. Is learning this worth the effort? It is according to Frankie Kemp. In his blog article (you’ll need to sign up for SmartBriefs to read it), he describes these seven Unexpected Ways That Gestures Can Up Your Leadership Communication:

1. Become more trusted – Based on studies, including an analysis of TED speakers, those who used gestures were trusted more, People saw those who didn’t use them as cold and logical. You would think being logical would be good, but audiences want and need to connect to speakers. Additionally, I think they are also reacting to that mixed message. Your body is indicating uncertainty and stiffness. The message becomes: Why should they listen to you?
2. Dispel nervous energy – Hand gestures that correspond to your message give you something to do to keep them from shaking. Meanwhile your messages are in sync.
3. Be more succinct – You won’t need as many words when your verbal and nonverbal messages are in accord. This gives you more time to interact with your audience, improving the quality of your presentation.
4. Increase problem-solving capacity – Suppose someone in your audience asks a difficult question. One of the easiest ways to draw on your expertise when you answer – is to move. According to Kemp, studies show we problem-solve better when we move. While you are doing so, you are also taking in more of your audience and maybe standing more directly in front of the person who asked a question, making them feel seen.
5. Increase your self-confidence – In another study, it’s been shown that positive posture (head up, shoulders back, spine straight) not only affects the viewer but has an important impact on the speaker. Testosterone goes up and cortisol (stress hormone) goes down; your self-confidence automatically lifts. If this feels new or uncomfortable for you, practice your posture-pose before presenting. You might want to do so before a meeting with your principal, too.
6. Achieve more credibility and presence – Kemp points to research showing those who use hand gestures and had more frequent eye contact with the audience (as opposed to darting around) and were more trusted. From what I have experienced, it is also because the gestures send the same message as the words.
7. Be seen as fair – When making eye contact, don’t focus on the same few members of the audience. That can send a message of excluding people. According to Kemp, it can even be seen as a micro-aggression. Allow your eyes to sweep the attendees, resting on different people each time.

As a leader, there will be many occasions when you must speak professionally and when it’s important that your message be received. Whether before an important individual or a group of teachers, parents, or fellow librarians, you need to become comfortable in these situations. Be mindful that you are always communicating and work to send the consistent, clear messages you want.
