There are many examples of questions that are perfectly valid and on-topic (in my opinion), but show very little research effort. I feel like some users are posting whatever comes to their mind on this site at high frequency.
In "Would a post-human alien civilization have entertainment?" it is being asked whether "an alien civilization that is billions of years more advanced than us" would still have entertainment. (in my opinion clearly POB, hence casting my VTC)
Some questions are also not quite thought-out. In the example of "Could a humanoid alien have a tail?" OP is asking for a justification to have a humanoid alien grow a tail, but presupposes them to have several other not less significant alterations (four arms, raptor legs, elongated xenomorph-skull).
The user I referenced asked 22 questions, with one popular question (49 votes) and the rest ranging from +4 to -5. If we exclude the one popular one the other 21 have a total score of -12 (+11/-23). Of the 22 questions 10 are closed and one I just casted a VTC on.
While most of the closed questions are older, 2 of the last 5 are closed, one currently being voted on, too. So it does not appear that this specific user learned from prior closing of questions.
The close reasons are mostly POB and too broad. One being off-topic and one duplicate. From the comments of these questions the downvotes are mostly stemming from lack of research effort.
While that is not a bad thing itself:
They asked 22 questions, mostly did not edit their questions upon being hinted that there is something structurally or otherwise wrong with them (one exception being this), did not participate any other way than post their questions, neither on Main nor on Meta - at least I could not find anything.
Personally, I get the feeling with some users that Worldbuilding.SE is their replacement for research effort. After all, it is simpler to write a 1-2 paragraph question than to do research yourself.
What is the right way to deal with behaviour like this?
The problem is currently being dealt with downvotes and the closing of question. Can we encourage users like this to do some research before posting their questions? Are there other, possibly better ways of dealing with this?
(After all, the referenced user seems to exhibit no change in behaviour regarding the improving of questions. So success appears to be very limited.)
I am not bashing the user I referenced. I just stumbled across one of their questions and knew they fit the pattern I wanted to describe. There are other users that fit this, too. It was just easier to pick examples going through this users' questions. I just used them as an example as they are a strong exhibitor of this behavioural pattern.
