> My point was more that if you’re trying to decide which method is better for remembering something (handwriting vs. digital), the introduction of a spaced repetition system (either software like Anki or a Leitner box for handwritten notes) will outcompete either one that is used alone.
The study in question compared three groups (pen & paper note taking, smartphone and tablet) on information retrieval and note taking duration after reading a dialogue.
Maybe I'm misunderstanding your point, but that systematic spaced repetition will lead to better information retrieval is kind of obvious and has a lot of literature to support it, but how is it relevant to this study?
