It sounds to me, DMcG, that when all else fails, you recommend intuition.

I'd say that intuition is scarcely different from guessing. I wouldn't rely on intuition unless I had to. (Though intuition is obviously useful for suggesting lines of research.)

When I voted in the U.S. yesterday, I was expected to vote yes or no on five complicated, proposed city ordinances. I voted on the three whose meaning was clear, and I abstained on the other two. I could have used my intuition, but it would have been irresponsible to cast a vote one way or the other on something I didn't think I understood.
