How to designate a human production which enables/stimulates/fosters reflection on a given topic?
I would call it intriguing:
arousing one's curiosity or interest; fascinating.
- e.g. an intriguing story (Oxford Languages)
There is also the compound adjective thought-provoking:
making you think a lot about a subject:
- e.g. a thought-provoking book/film (Cambridge)
As verbs you could use inspire, trigger, prompt.
