Wished to write this a long time ago, and the last drop was this question As a time traveler, how would I see quantum randomness change history? really, you are serious this was a hard science question? (btw maybe someone should remove the plates for HS tag when it is not HS anymore)
Making a good hard science answer is a hard work, a lot harder than usual. Making hard-science worth question also a hard work, but I didn't see the question which did their homework in that regard. (A few questions kinda did it)
I think we can make a favor - to mods, to those who would like to answer hard science questions, for those who would have real hard-science answers - by redefining the procedure of asking hard-science questions.
Step 1. Asking a reality-check + science-based
After getting enough attention, choosing probably more or less scientific answer and if the OP still needs so, after the first step the OP can go further.
Step 2. Asking a hard-science question
The question should contain in the header the link to original science-based question, the link to answer the OP has chosen as key which explains what he actually likes to get in a bit more scientifically valid way and might be a slightly improved version of his original question (which does not alters its sense, and if he is not certain than the original question)
The first step intended to help OP to formulate the question in a proper way, and determine if it is suitable to be answered in hard science way (helping the OP too).
As the result, we will probably have a question worth to spend 1-2-3 days to answer (helping the fans of hard-science)
Formatting the hard-science question in a proper way, which clearly distinguishes them from other types of questions will probably help mods in a way of eliminating the need to attach the hard-science plate to each of such questions and answers for the question.(and have no problems of removing them as in the question above)
It also will be a help for editors to clearly see if an OP has understood and read the requirements for hard-science question and do not confuse it with hard science fiction definition (helps OP and editors and quality of the tag on WB)
Having softer and harder versions of a question will allow those who would like to answer that type of question to participate in their weight categories (helping those who would like to answer and the OP).
Having a better quality of hard-science question might attract those who would like to provide such type of answers, and most importantly can provide it.(helps quality of such answers)
It still does not solve the problem, and it is not some kind of ultimate solution, but it probably might improve the way of handling hard-science questions in terms of formulating them, editing them, providing answers.
I guess it is fair if OP will spend some time to refine his views before someone will spend a lot of time in formatting nice answer to the question.
Those who are not certain of their capability in defining a scientific value of a question will have more information available for them to make their decision and vote for HS variant of a question.
It does not have to be a strict or enforced rule, it can be started as a good manner and stay so. I or any like me, knowing that OP have a good manner option, will be more certain how to vote, which is not the case now because the OP do not have a community approved option (a duplicate Q danger) and I'm not sure did he read the tag description and it is his conscious choice or he didn't and do not understand what he is asking for.
What would/should humanity do with a copy of the Encyclopedia Galactica?
No one, including me, have not removed HS tag in the question - but really, in the situation is just an easy fix, as it is obviously a new user just didn't saw the description of HS tag and to replace HS tag with more appropriate to the situation is the same as I edited the answer to insert comma in a sentence there.
5 answers - none of them is hard-science as it is defined in tag description.
