I asked an OP to provide some context and research for their question (see below). I believed that it could have been answered by using basic resources. I did however think it might be a good question if the OP gave evidence of research and that the research had failed.
The OP agreed to do the research and return.
In the meantime, despite the brief conversation between me and the OP about this, people answered. Presumably they had seen the conversation and simply ignored it.
I down-voted someone for not waiting for the research promised by the OP. It seemed to me that this was a valid reason for down-voting.
Note that a discussion ensued in comments. I have permission to refer to this from the other party involved. It is in this question. Contesting the palm” — looking for a definition and possible origin of this archaic phrase
Here is one of the arguments I used:
Suppose someone asked, "What does 'incomprehensible' mean and they didn't give any research or explain why it was difficult for them. Would you answer or would you vote to close because they should have used a dictionary? The OP could have looked up the same sources you did. If that still didn't make sense in their context then they would be justified in asking.
Is that a valid argument?
