I digress. My point here is to point out that without knowing it, I have spent my whole life speed reading (well, I didn't know it until I was a young teenager. That's when I saw an episode of 20/20 about speed reading wherein a man read a looong novel in the time it took someone to bake a pizza. Speed reading was explained in the segment.). When I read, my eyes don't move side to side over every single line of text. Instead, my eyes focus pretty much on the center of the page and take in the page as a whole. I'll let the infographic below explain. Very occasionally, I will realize that I missed something and have to flip back, but this only happens when I am reading a mystery and a very subtle clue was dropped. In both my undergraduate Honors classes (humanities classes, essentially) and in graduate school, we would have hundreds of pages to read per night, and I could not have read everything without reading as I do. In fact, people who read every single word simply can't get through a reading intensive graduate program. It won't happen. Plus, when you're reading academic papers, not only is it not necessary (unless you're the peer reviewing for the peer reviewed journal), but it might just turn your brain to pudding.
Without further blather on my part, I give you "The Science of Speed Reading"
