Yeah, instead of "insert," I tend to ask myself, "What do I know about this situation?" or, "What do I know about these people?" And sometimes it's mature stuff like, "Well, she and her mother have this thing in their relationship where they have these random late-night talks about what they want out of life, and that really hasn't come out in the book yet, so this would be a great time for them to do that and for it to get interrupted by this other plot point event." And sometimes I'm like, "I know that there are pumas in cravasses! But these are not regular pumas!" The knowledge does not always have to be, like, mature erudition.
