The gist of this request has been made before, but that post was from 2011 and is effectively status-complete due to the passage of time. And the answers there don't reflect what sites have available to them.
The Stack Exchange network has changed significantly since that question was asked, and has introduced sites whose subject matter includes those of licensed professionals. (Engineering, Health, Law ...)
On Engineering Meta and Health Meta, their communities have discussed the matter of site specific disclaimers. After some amount of research, those communities interpreted SE guidance to mean that per-site disclaimers were not necessary. (See Engineering and Health)
But with that being said, Health has a disclaimer:
as does Law:
Our Law site has a broader general disclaimer written as a Help Center article based upon some consultation with legal experts. I don't know if Health has an expanded article or not.
And that kind of opens up a whole can of worms for SE to resolve. Doctors, Engineers, Lawyers, Nurses, and other professionals are required to be licensed in order to be allowed to practice their craft1. Having sites built around those professional experiences opens the door to misinterpretation regarding professional advice being offered within an answer.
Having a few sites, but not all sites, with a per-site disclaimer is also problematic. It opens the door for someone to state "Law has a disclaimer, but Engineering doesn't. Therefore I can put more trust in the answers on Engineering as professional advice." It's a bit absurd but it is a common logical fallacy and the claims will happen.
It will also lead to answers that start with "I am not a licensed professional engineer in your jurisdiction and this answer cannot be construed as professional engineering advice." Which is just wordy, unwieldy, and kind of ugly looking.
Would SE please pick one of the two options or come up with a superior option?
- Provide a general disclaimer for all sites that involve licensed professionals
- Provide clearer guidance within the Terms of Service / FAQ / wherever as well as removing all per-site disclaimers.
1 Note: not all roles in those fields require licensure. But by and large, they are licensed professions.
