Obviously we have the benefit of hindsight, but “do heavy objects fall faster” doesn’t seem like a stupid question to me in the same way that “do chimpanzees like crystals” does.

I think we can call them both stupid in they are malformed.

Let go of a feather and brick on the ISS gets a different result than doing so on top of Mount Everest. Similarly understanding chimpanzees behavior is a deeper question here noticing some chimps find some crystals interesting in some situations and moving on.
