The March 2026 issue of 'Solid Copy', the newsletter of CWOps (https://cwops.org/current-month/), features a paper of mine, "Empirical Findings About Morse Code Learning and the Need For Further Research". I wrote it while researching how much of current Morse code learning lore had actually some empirical support. Comments welcome!
