Mehrabian’s 7-38-55 Communication Model

Albert Mehrabian’s 7-38-55 Communication model says that only 7% of communication takes place through the words we use, while 38% takes place through tone and voice and the remaining 55% of communication take place through the body language we use.

Summary by The World of Work Project

The 7-38-55 Communication Model

We are often told that tone and body language play a huge role in the our communications. This is part of the reason that emails are less effective that telephone calls, which are less effective than video calls which are in turn less effective than face to face meetings.

Based on research, Albert Mehrabian has concluded that only 7% of communication takes place through words while 38% takes place through tone and voice and the remaining 55% take place through body language.

The clear lessons from this research is that we need face to face communications, at least some of the time, if we are to communicate effectively together.

The World of Work Project View

We are slightly wary of the numbers within this model from a work context, and even Professor Mehrabian called out words of caution around the absolute accuracy of these percentage in his work. He noted that his research focused on the communication of emotions and feeling, and acknowledged that contributing factors will be quite different when different topics are being discussed.

Regardless of the exact accuracy of the model, or the specific topics of conversation that it relates to, we like it. We know the numbers could be materially incorrect, but we still think the underlying message, that words alone don’t constitute communication, is very important.

Many individuals and leaders fail to appreciate the importance of other means of communication. By focusing on non-verbal signs from others they can improve their awareness of others and their awareness of the impact of their words and actions on others.
