I have looked through our tags, and have found the following list of tags that seem to be (at least in part) about doing research in cogsci:
experiments - 5 questions
reproducible-research - 4 questions (I don't understand what this tag is about, can someone clarify in comments or an answer?)
reference-request - 4 questions
apparatus - 1 question
tools - 1 question
experimental-design - 1 question
publication - 1 question
resources - 1 question
Do we really need that many tags? Can we merge some of them in a smart way?
It seems obvious that tools, resources, and apparatus should all be merged together. I would also suggest that they be merged into some sort of bigger tag that covers experimental-design and some of the questions tagged experiments. I would propose we name such an overall tag as methodology or research-methodology. I think the first is a better name, but the second would be easier for new users typing in the tag-box to find.
The tag experiments seems to be a particular sore point. One question is about running experiments, and thus would fall under a broad methodology tag. The rest of the questions just seem to be stressing that they want references to experiments, or just references... in this case I think those 4 questions can either have the tag removed (since we should be pointing out experiments anyways in our answers) or atleast changed to reference-request if it is obvious that they want reference to specific studies (as is here and here).
I wanted to run this observation past the community before making any changes. Do my suggestions seem reasonable? Also, what is a better name methodology or research-methodology?
