* "Don't needlessly struggle" view: a good explanation should be ''easy'' to process, and be as intuitive as possible. [[Aim low]] [http://lesswrong.com/lw/kh/explainers_shoot_high_aim_low/].
* "Struggling is important/essential for understanding" view: A good explanation should be effortful for the [[learner]] to process. It should e.g. present misconceptions and make the learner
to "do the work".
The truth might be some sort of mixture. To optimize for struggle would be to e.g. put the [[learner]] in a psychologically stressful state, with little support, to deliberately confuse them, etc., which seems unhelpful. On the other hand, it isn't clear what a totally intuitive explanation would look like. There might even be a "valley of bad intuitiveness", where a small amount of intuitiveness is bad.
