Sometimes you hear a guy with a leader voice in a non-leader job and it immediately seems out of place. I wonder if the voice quality makes leadership more feasible or if the body chemistry that promotes leadership (say testosterone levels for the sake of argument) create an excellent voice as a side benefit.
There are plenty of leaders with sketchy voices, of course. Bill Gates comes to mind, as does the first President Bush. Obviously there's more than one way to get to the top. But I wonder if we will ever see a medical procedure to turn normal voices into leadership voices for the purpose of furthering a career.
My guess is yes.
