In the real world, using her perspective, she has brought positive reinforcement (clicker) training to the dog and zoo worlds, gave confidence to hundreds of thousands of breast-feeding women, developed techniques for teaching people with autism, and has changed how surgeons learn their skills which in turn creates less stressful and more error-free operation rooms. The common thread through all of her work is how she effectively reduces gratuitous violence and creates a culture that is productive, yet filled with kindness.
