Are there studies showing that descriptive notation is easier to use for blindfold than algebraic notation? What studies have compared effectiveness for thinking by chess players using descriptive vs algebraic notation?
If there are studies, they'd show descriptive to be the lesser of the two because in descriptive, all the squares have two names; in algebraic, just one. So if you're having to keep a game in your head, it's easier to do so with 64 identifiers to remember than 128, right?
If you practice playing blindfolded, you'll find that your only use for notation is transmitting the moves back and forth.
