You’ve linked peer reviewed studies showing the marginal benefits in scenarios that don’t apply to most people most of the time. It’s not that there’s absolute zero benefit, just not enough benefit to keep teaching it. School is compulsory in the U.S. so it’s important that we choose subjects that stand to benefit American students the most. And an archaic writing system that the vast majority of students will never use again once leaving grade school is not a great benefit. It’s not a “dumbing down” it’s a trimming of that fat. We taught cursive in schools for centuries, and it’s just not used anymore, so why keep teaching it?
You’re still on your high horse and talk down about American education and yet here you are on Lemmy struggling to form a single coherent thought, losing track of the thread of argument, and just repeating the same thing over and over without making any real substantial point. Evidently your education wasn’t the hottest either. Probably because they have too strong a focus on nonsense like cursive script.
