A recent question was of the form "Is X the superlative?"
I want to suggest we change such questions to ask "What is the superlative?" as a matter of policy.
The question attracted a lot of answers, but since it was phrased as a yes/no question, every answer amounted to "no".
Then, OP accepted the answer that described the superlative from among the answers posted up until then, indicating they were really asking "What is the superlative?" in the first place. So I changed the title.
Asking "What is the superlative?" is a common tactic of asking a potential list question so that it can have a single answer. SE's purpose is met, and we learn things and have fun along the way.
It's OK if OP suggests a candidate the way it happened in this instance, and does indicate some initial research effort. But it's an XY problem to ask, as a yes/no question, whether the candidate is the superlative. The mere act of asking means OP isn't sure.
So, should we discourage questions that ask for a superlative that way, and prefer that people just ask for the superlative?
(I had originally thought of the stronger proposition of discouraging all yes/no questions on main, but decided to narrow it)
@Valorum asked for some more examples. Searching SFF:SE for questions with "First" yielded:
