This isn't an answer to whether or not we want reference-request, I'll let the community decide that.
This is an answer to say, as it is now, the tag is being misused and we should remove it from questions unless they are looking for a specific article.
As an example: http://cogsci.stackexchange.com/questions/3352/what-is-the-study-which-shows-that-babies-can-teach-young-children-empathyhttps://cogsci.stackexchange.com/questions/3352/what-is-the-study-which-shows-that-babies-can-teach-young-children-empathy
I was looking for the actual name of the study. I knew there was a specific reference I was looking for. That's the proper use of this tag. Just "give me some reference, any old reference" is an incorrect use for this tag.
