It was fascinating to analyse a #MelindaGates interview on BBC Radio with public health advocates on our recent ’20secondsmedia’ media training & public speaking course in Amsterdam. Among the many elements that became abundantly clear in her performance was the power of muscle memory. She had, of course, worked hard overtime to remember key messages. Hence, during a challenging series of exchanges with the interviewer, who tried on many occasions to induce her to criticise D Trump and the Pope, she never wavered. She kept bridging back into her key messages and hammered them home. It was a performance that drew heavily on instinct; those key messages about child mortality absorbed in her muscle memory. It shows that effective, polished public speaking, like high-level musical and sports performance, is the work of many years of hard work. You drill, and drill, techniques and allow them to seep into the memory. Even if your mind goes blank, the muscle memory will rarely let you down.
