It's interesting to experience your brain relearning a habit that has become so ingrained. Reminds me of the Smarter Everyday backward bike episode [1]. In fact, I just tried to tie my old 2 loop knot and accidentally tied Ian's knot again.
I also taught the knot to my 10-year-old just to see what she would make of it. Took her three tries to understand and now that's how she ties her shoes. It seemed much easier to explain than the standard.
