Many people are afraid to assert themselves, Dr. Alberti, author of Stand Up, Speak Out, and Talk Back, thinks it’ s because their self - respect is low. "Our whole set-up is designed to make people distrust themselves, "says Alberti, "There’ s always ’ superior’ around a parent, a teacher, a boss who ’ knows better’. There superiors often gain when they chip away at your self - image."
But Alberti and other scientists are doing something to help people assert themselves. They offer "assertiveness training" courses, AT for short. In the AT courses people learn that they have a right to be themselves. They learn to speak out and feel good about doing so. They learn to be more active without hurt
