Some time ago, John Rennie asked,
...in many cases it looks as if the OP simply can't be bothered to put any effort in. Do we have a policy for closing (or not closing) such questions?
The Meta question has received not a downvote (12/0 at time of writing). The answer by Ben Crowell says (emphasis mine)
The help section "What types of questions should I avoid asking?" does not say anything about insufficient research effort. This suggests to me that ofeeshul policy is to downvote these, not close.
This answer also received no downvotes (7/0 currently), suggesting the community agrees that this correct: insufficient effort questions should be downvoted and not closed.
Despite this, several 3k+ users have voted to close questions due to "insufficient effort." This leads to the question at hand:
Should we change current policy on insufficient effort questions?
