Should a question based on false premise be closed?

Question

There is an argument saying that questions based on false premise should be closed*. An example question of that argument is "How's X helpful?"**. According to the argument, that question is based on a false premise because X couldn't be helpful in everything.

I don't agree with it, since having a false premise is natural when we don't know much about a thing. Even professional researchers can base their studies on false premises. A false premise doesn't make the question off-topic or unclear. A false premise question is a good question since we can learn a lot from it, and deserved an answer to correct it.

But that's my though. What do you think?

Answer 1

It depends on the question, and the false premise.

Is X helpful? should be closed for any number of reasons:

• It's too broad (helpful for what?)
• It's likely based, at least in part, on a false premise, as you describe (X may be helpful in some situations, but neutral or harmful in others)
• It may not be clear what's being asked (because we don't know what the OP thinks it's helpful for)

Other questions based on a false premise can be perfectly acceptable, and answers will generally clear up the confusion. One example: When using flashcards, should the word or the definition be hidden?
