I like writing by hand, but I don’t agree with the logic that it’s good because it recruits more areas of the brain. The less effective the medium is, the more of the brain it will recruit; chiseling on a stone tablet is probably a more complex task and it probably gives a more broad stimulus to the brain, but it does not mean it’s such a good idea. I would personally prefer to use a text editor for effective writing and then crochet for fine motor skill.
I agree that “more areas of the brain” does not mean better necessarily, however I do wonder about the chiseling stone thing.
If you chiseled some formula or something into stone you’re unlikely to forget it any time soon. I wonder if forcing yourself to ruminate over something a bit longer than it takes to type it, in a way that can actually hold your attention or repeatedly bring it back to the topic, doesn’t indeed help.
Right, it's a false signal. It doesn't mean that more things are retained.
I think what happens in these types of threads is that the people who like handwritten notes, perhaps even obsessively so, all pour in. But that population of handwriting fans isn't necessarily representative of the population overall.
