Yeah you're entirely right. I was a history student in undergrad and graduate school, and obviously this sort of thing does occur naturally in some courses. But

Yeah you're entirely right. I was a history student in undergrad and graduate school, and obviously this sort of thing does occur naturally in some courses. But I do think it's still fairly rare that someone intentionally strategizes working backward in a rigorous way. I mean again, I don't consider this some be-all-end-all, I just consider it a viable strategy (among many alternative viable strategies). Mostly I'm responding to the opinion that this couldn't feasibly work.
