It’s a compression format. Having to explicitly remember (page 100, para 30) taxes memory. Since Brains are pattern recognition systems a pattern that can be easily decompressed and used to predict the next verse reduces cognitive burden. - Human brains do not store information in a format that can simply be traversed and recalled instantly. - We rebuild specific memories, based on associated precursors or memories. - The text vs audio vs touch distinction is irrelevant to a brain. Your brain will remember whatever you felt when you read Hamlet, including the sounds of the words or the smell of your bed room. - short term recall is 7-9 ‘things’. - Long term, short term and medium memory function at the same time (parallel, not sequential) In a nutshell, it’s cheaper to use multiple systems to rebuild the information.
