I noticed something interesting just now: I tend to read backwards. Most web pages, and a few books, have a very low signal to noise ratio, so rather than reading everything, I skim over for interesting keywords and phrases, then quickly backtrack to the point where the ideas leading up to the interesting phrase began. This means I’ve already had a sneak preview in reverse of everything I’m about to read in detail. Sometimes the process of backtracking is enough for me to realise that the idea isn’t deep enough to require a detailed read, so I don’t bother reading it forwards. Result: most of the webpage goes unread, except the good bits, which I read backwards. This is highly unsound.
