What is the strongest objection to my conclusion?

Before you present a finding to people who will push back on it.

Here is a conclusion I have reached from my research. Find the objection that would hurt most.

1. Give me the single strongest objection, stated as the smartest person in the room would state it, in their words not mine.
2. Explain exactly which step of my reasoning it attacks.
3. Rate it: fatal, serious, survivable, or weak. Be honest even if the answer is fatal.
4. Give my best available response, and say plainly whether that response actually works or merely sounds like it does.
5. Then list the two next strongest objections in a line each.

If my conclusion is fine and the objections are all weak, say that instead of manufacturing a critique.

My conclusion and how I got there:

Pressure-testing a conclusion. Counter-evidence, gaps, and the strongest objection, found before someone else finds it for you.
