I’m not really sure what you’re trying to say here? if I say “I generally prefer a demonstration to an explanation” that’s the same thing as describing my “learning style” its personal preference, we don’t need scientific support for that any more than we need scientific support for people having different favorite foods
I don’t understand what you’re saying is debunked still, exactly the concept that people prefer different methods? that doesn’t make any sense. If you’re saying there’s no statistical difference between learning outcome with preferred method or other methods, sure, but denying that people have preferences just doesn’t make any sense
