@fyrepenguin it's not a bad approach
actually, from what I've heard, it's the best approach
this comes from the literature on learning and acquiring expertise, regardless of domain
apparently they found that novices and maybe intermediary people do a task best if they are meticulously focused on every detail. They should have no distractions, and they should keep their mind on the steps, actively reflecting.
And conversely the experts do a task best when they aren't focusing on every detail. If they try to, it becomes counterproductive
explained by the metaphor of trying to run while directing every single muscle to do the right contraction at the right time. You'll fall down in a heap before you make one step! But if you are told to run and you just run, you can do it. As long as you don't think how your body is doing it.
I only heard it retold in an interview, so it was a very condensed version of the original studies, and I don't remember it perfectly
I think the interviewee said that there was an experiment with surgeons, where the novice doctors needed the concentration. But then they also experimented with expert surgeons, who did better when distracted (e.g. by listening to music) than when not.
Sorry, lapsing into lecturing again :)
