One reason why people might avoid skill checks is that failure can carry negative consequences. I agree that it makes sense for anyone to attempt, say, a monster knowledge check, since failure simply leaves you in the same place as no attempt. Trying to jump a pit on the other hand? Failure can be MUCH worse than not trying at all. Diplomacy is definitely an area where failure can carry negative consequences.
Moving to the current situation, they way you used the word "divine" did not, to me, particularly say that a Religion check was necessary to figure out what was going on with the pool. Not only do I not expect to have to interpret sly puns for clues, it was also very possible to interpret the phrase as referring to a divining rod, which I would read as Nature (or Arcana, but that had been eliminated).
So on the one hand, I understand where you might be frustrated that no one was attempting a full array of knowledge checks. On the other hand, you were being rather coy about which knowledge was applicable. There's absolutely nothing in your initial description of the alcove to hint at a religious presence. And while you did reference churches in your response to Viator's Arcana check, that came right before the action sequence with the scrying pool. Frankly, I completely missed that reference at the time, and I suspect the others did too (I only spotted it because I like to double check myself when talking about things that others have done).
As for why Ah-shahran hadn't made any checks? I think the IC post answers that.

I guess that's why we don't!![]()
