Maybe I'm still doing some heavy priming by using multiple prompts, but similarly you can follow-up any speculative prompt with a "now flip the framing to x" query to ensure you are seeing the strong cases from various perspectives. You must be honest with yourself in evaluating the meaningful substance between the two, but I've found there often is something to parse. And the priming I suggested is easily auditable anyhow: just reverse the prompt order and now you have even more (often junk) to parse!
