I do like your fiber analogy. I wholeheartedly agree metaphors are a multiplier to information transfer, but I can't say I've seen a deep dive into the psychology of why beyond simple literature class reasons. My guess is when given a metaphor our brains just don't have to do as much work to frame the concept and understand it, and retention is better as it's condensed.
