I kind of liked the idea that forgetting what you've learned and then relearning it is the best way to learn stuff. I've said the same thing over the years. Well I said it's quicker to relearn something than to bother to try to remember it. My grandmother described it as kids know something one day and they don't the next because it's no longer accessible in the front of their mind. Everything they've learned is still in there somewhere and they'll get back to it sooner or later. This article just described it like, "no one knows for sure why. The idea is that forgetting is the friend of learning. It may be that the brain when it revisits the material at a later time has to relearn some of what has been absorbed before adding new stuff. And that process is re-inforcing. When you forget something it allows you to relearn and do so more effectively the next time you see it."
I Agree. And they said it more clearly than me. That's probably why they got the job at the NY Times.
