What makes public speaking so scary

Many people can be shy. And mess up during a speech or say the wrong things and it can end up all over the world.

We're scared to speak in front of a group because we're scared people will disapprove of us. We're frightened of social disapproval. This goes back to our earlier days when we were being viewed as foolish or inadequate by a group could lead to a loss in status, mating opportunities, and much more.
