Expertise is a curious thing when it comes to the field of communications. It is hard to state that anyone one can be an expert at communication, because this is such an all encompassing statement that it almost is redundant. An expert at communication almost sounds like they should speak all languages, and understand every form of sending and receiving messages. The field of communication covers everything, from types of communication, to communication theories. These communication theories can contradict one another, and related to a certain situation. Expertise comes in a different way with communications, and that is an in depth understanding of multiple theories, combined with a keen eye. These theories make up the field of communications, from the earliest theory created by Shannon and Weaver, to the linear model and further behind.
However as stated above, expertise is tricky, and even a textbook memory of theories wouldn’t make you a communications expert unless you can observe them. Part of the amazing nature of communications comes from this opening of your eyes, being able to apply the theory to your everyday life, and see it unfold before your eyes. The awareness of body language, the choice of words, how they hold themselves, how they present themselves to those around you. Without the ability to do this communication will be a lost cause for you, because this is where this section of academia becomes really amazing. This combination of awareness and knowledge is what makes someone an expert in the field of communications. Some of the best examples of Communication experts can be found on the NCA website which is further mentioned in Discourse Community.
