A July 2022 renovation of the reality-check tag and others has changed the context of this question. It is now obsolete. Please see the following question and the link under "Conclusion." If we can't burn the "reality check" tag, can we rename it?
i just think the name reality check misguiding/misleading, or not a good name for a tag that supposed to be asking a concept is possible or plausible for a fictional world building, base on the answer from here What is reality check suppose to be? rather than checking are the concept is real or checking reality or can be real, i know people like to use the term realism, but most of the time when i see people use this, they more referring the authenticity or accuracy of the concept base of real world or the existence in real world.
the new answer in my question here make me decide to ask, but i am not really understand english so maybe i was wrong or what i mention is no different, but at least for a new member that looking for first glance, that what i believe they think it was supposed to be about checking reality or has the real counterpart. (i do think so at first too)
also with this i think it make it possible/encourage for people with some magic or not base of real thing to use this tag regarding their concept, but if the tag become to broad or what i believe it suppose to be is wrong, and it actually was a tag for authenticity or checking reality, maybe make a separate tag for that.
in before you ask me to change the name myself (in case i have enough point to do so) i prefer someone else do it (i even just know you can change the tag name and i dont know how to do it anyway).
I don't know much about the tags or rules in Meta, since I usually just briefly lurk, so I'd appreciate it if someone can fix the tags to be more appropriate and I apologize if I've broken any rules here.
self-consistency-check- it is what "reality" is about in the tag. it's not about being "real" but whether were the premise real, some element would make sense. E.g., "if people had three eyes, would there be place for spectacles for two eyes". In the real world we don't have three eyes but we can make inferences about the fictional word. $\endgroup$
