We kind-of discussed this in a related post.
We recently got two questions tagged mental-health:
- How to overcome these learning difficulties and progress in academia?
- “Anonymous” is so distressed that he is having trouble functioning [duplicate]
Then again, disability explicitly covers "cognitive, mental, sensory, emotional, or developmental" impairments. So mental-health seems to be a proper subset of disability.
Then yet again, most of the disability questions really could be retagged mental-health. Explicitly, I'd argue that out of 20 disability questions, all but the following could be tagged mental-health:
- Does disability impact on prospects of employment in academia?
- Dismissed by my committee
- Disclosing hidden disability to employer
- How does Stephen Hawking conduct his research?
(Yes, I'm putting speech impairments under the "mental" category here, since they usually involve language centers in the brain, unless there is some trauma to the vocal apparatus. Clinical psychologists, neurologists etc. are welcome to correct me.)
I see a couple of ways to proceed here.
- Clearly separate physical and mental disabilities, by tagging the 4 questions above physical-disability, retagging the other 16 disability questions mental-health, black-listing the disability tag, and adding mental-disability as a synonym for mental-health (so people find it when they type "disability" into the tag box).
- Merge the two concepts, by retagging the mental-health questions to disability and blacklisting mental-health.
- Do nothing, and let nature take its course.
Given that I see three alternatives, the usual upvote=yes, downvote=no meta mechanism won't be useful here. So I'll create three answers corresponding to the three alternatives. Please vote your preference, and comment as appropriate.
