Also, a novice is more ready to learn a lesson on the way back from a dead end than while barreling down towards it.

(author here) This is an interesting point. I hadn't considered it, but I agree. Or maybe to be more specific, I think the novice has some prior that their idea will work, and hearing an expert's disagreement will update their prior somewhat. If the novice has a high respect for the expert, that update will be large enough. But sometimes the novice just has to experience the pain firsthand in order to truly appreciate why something is a bad idea.

Advice while struggling is the key. I mentor a few friends, but if I'm giving directions, it is kept vague so that the task is still done by themselves. A proper review is only done after they tried or completed the tasks. This way, they already know the scope of the problem so the solution is way more understandable.

I often find myself smiling and joking with novices as I meet them coming back from a dead end, "yup, that's exactly the problem I suspected you'd have, now let's see how and why it happens, and how to move forward".

There might be some situations and some people for whom this would be immensely irritating, but for the moment as far as I can tell, it's going ok with my novices. But your essay opened up a reflection in me about how people perceive this and if I need to tone it down. Thanks!
