This phenomenon is known as Alien Hand Syndrome or anarchic hand, where one hand has a mind of its own and acts independently of the other. It occurs when the corpus callosum, the bundle of fibers connecting the two hemispheres of the brain, is cut. As a result, the two hemispheres of the brain are unable to communicate effectively with each other. In Estell's case, she says she does not know the answer while pointing it out with her left hand, suggesting that her left hand acts independently of her conscious awareness.
