==Relation to idea inoculation==
Scope for improvement seems related to [[idea inoculation]] and [[inferential distance]]. If the scope for improvement of a technique is not made clear on initial exposure to the technique (e.g. due to a large inferential distance between the [[Explainer|person explaining the technique]] and the [[Learner|person reading about the technique]], or the person explaining the technique not being an expert), then this person can develop a resistance to further attempts to explain the technique (due to idea inoculation).<ref>Duncan A.

* [[Spaced repetition]] seems like a [[learning technique]] with large scope for improvement. My impression is that most people use it for things like learning foreign language vocabulary and other "isolated facts" they want to memorize, and conclude that there is little scope for improvement. What they don't do is look at the "masters of spaced repetition" and try to cultivate the skill of using a spaced repetition program for understanding. [[Michael Nielsen]]: "I'm particularly grateful to Andy Matuschak for many thoughtful and enjoyable conversations, and especially for pointing out how unusual is the view that Anki can be a virtuoso skill for understanding, not just a means of remembering facts." <ref>http://augmentingcognition.com/ltm.html</ref>
* Probably many mundane skills like the skill of counting has limited scope for improvement. Most people can't learn to count many times faster or many times more accurately or to very large numbers. (At that point, they would probably want to make use of a counting device that just supports an increment operation.)
* Probably a learning technique like highlighting/underlining also has limited scope for improvement.
