Communication is about getting others to adopt your point of view, to help them understand why you’re excited (or sad, or optimistic or whatever else you are.)If all you want to do is create a file of facts and figures, then cancel the meeting and send in a report.
Our brains have two sides. The right side is emotional, musical and moody. The left side is focused on dexterity, facts and hard data. When you show up to give a presentation, people want to use both parts of their brain. So they use the right side to judge the way you talk, the way you dress and your body language. Often, people come to a conclusion about your presentation by the time you’re on the second slide. After that, it’s often too late for your bullet points to do you much good.
You can wreck a communication process with lousy logic or unsupported facts, but you can’t complete it without emotion.
Logic is not enough.
