This is actually a story about expectations — how our expectations can affect people around us. For example, if someone is blind and they are allowed to grow up without preconceived notions or artificial limitations, how much will they be able to do? Can they get to the point where they can, for all intents and purposes, actually see? Which leads to the question, what is sight anyway?
If this interests you, I recommend the following podcast — “How to Become Batman” (Jan. 22, 2015) from the NPR program Invisibilia. (Actually, all their programs are thought-provoking.) It was make you reexamine how expectations can encourage or impede anyone, including rats running a maze. Find it at http://www.npr.org/podcasts/510307/invisibilia
