" IDK how much difference the content of a doodle makes?" I'm a doodler. I also make art. And you are right, the cognitive load of the doodle makes a difference. My 'learning doodles' are really a mindless endeavor, and they only realistically look arty because I have been making art for decades now. The actual content of the doodle matters little. The real point is more keeping the hands busy and the mind lightly engaged with something else - I suppose it is akin to listening to a podcast while walking or driving. I can get something similar from taking notes, but even that is better if I have doodle space since I don't need to write everything down.
