At least in my case I'd like to think I absorbed the habit of recognizing sub-optimal traversals of data (for example, yesterday I was writing a parallel iterator and made the intentional choice to "waste" effort duplicating the map result than having to synchronize threads on mutable boundaries) but I don't remember all the buzz word jenga that was in my data structures class in uni.

I've often been able to dramatically improve other peoples' code by selecting the right data structure (array, list, tree, hash, whatever) where the original programmer clearly did not know about them. They were able to make the code work, but not very well.

It's hard to do research when one doesn't recognize there's a problem, nor know what question to ask.
