Devil's Twin

Critique finds weaknesses in your argument. The twin does something scarier: it writes the other side's argument, from their premises, at full strength — the memo your smartest opponent would circulate an hour after yours. If your document survives its twin, it will survive the meeting.

Required Inputs

• The document — full text. The twin argues against the strongest version of what you wrote, so it must see all of it.
• Who would oppose this in real life (optional but sharpening) — the CFO, the incumbent team, the sceptical customer, the regulator. The twin adopts their premises, not a generic contrarian's.

How the Twin Argues

• It starts from the opponent's values (their scoreboard, their risks), not from negations of yours — real opposition is a different worldview, not your worldview with "not" inserted.
• It concedes your strongest point early — sophisticated opponents do; conceding makes the rest of their case credible.
• It uses your own evidence where possible — the most damaging counter-memos re-read your data and reach the other conclusion.
• It is written to persuade your shared audience, in the register of your organisation — a memo, not a rant.
