e.g. a complex task is broken into parts A, B, and C. instead of learning A, then B, then C, you reverse and learn C first, then B, then A

in dog training and piano practice there is a method called “back-chaining” that can make a huge difference. it is basically learning in reverse

this works because as you practice the new chunk, you can flow it into the piece you already learned.

this doesn’t work in the normal direction because in order to get to the new stuff you have to retread what you’ve already learned. for a task ABC you will end overly proficient at A and frustrated and weak at C

this doesn’t even necessarily build proficiency at A because of how recall works. spaced repetition systems for example work on the premise that you have to (almost)FORGET in order to actually ingrain a habit.

back chaining naturally allows the bulk of your conscious attention to flood into the “Task at Hand” while also irrigating the more established tokens of knowledge in a maximally efficient way

using a programming analogy, regular chaining requires you to navigate your entire linked-list in order to iterate on appending something new. in back-chaining you always have the tail in hand and can immediately iterate on adding the new head.
