Two moves make this real: reading an argument someone else built, and building your own for a specific crowd. Both use everything from the last three rungs at once.
First, Read the Bones
Pick up any real argument — an opinion column, a campaign speech, a school-council pitch — and X-ray it. Where's the claim? What's the reason underneath it? What evidence is doing the proving, and does it actually prove that reason? Does the writer link back, or trust you to? And before any of that: has this person earned the authority to make the claim — real expertise and stake, or borrowed shine? Naming the bones turns "I sort of agreed" into a precise read you can defend.
Then Build Your Own — for a Chosen Crowd
This is the mastery move, and it's why the toy makes you pick an audience first. A case can be perfectly sound and still a poor fit — strong bones aimed at the wrong instinct. Who's listening decides what you lead with:
- A sceptical crowd (staff, a principal, people inclined to say no) → lead with evidence and earned authority. Show your reasoning and your standing before you ask for anything.
- A crowd that already agrees (fellow students at a rally) → you can lean harder on the reason and the feeling; the evidence is reassurance, not persuasion.
- A cautious crowd weighing risk (parents, a budget-holder) → name the objection early and answer it; show you've thought about what could go wrong.
The Whole Climb, in One Move
When you choose a position, earn your right to argue it, build claim → reason → evidence → link back, dodge the four leaks, and pitch the lot at the actual people in front of you — that's the entire concept firing at once. That's the difference between having an opinion and being able to make a case for it.
