But to read a Facebook post, you can skim instead of read. That is saying, putting just five percent of your brainpower into reading it, which is not really reading it. It’s trying to see whether there’s something in there that evokes your emotions, and if not, you swipe to something else. With paper it’s very hard because to swipe a paper takes a lot of time. You can’t help, but enter the more rational intellectual part of your brain.
