double-crux

What problem does it solve?

CFAR's Double Crux helps people resolve disagreements by identifying a shared underlying belief (the crux) whose change would alter the conclusion. This technique surfaces the real point of contention rather than debating surface claims.

Core Features & Use Cases

• Design Mode — Prepare for a disagreement by mapping belief structure and identifying likely cruxes
• Practice Mode — Walk through Double Crux on a practice topic to build skill
• Execute Mode — Facilitate real-time Double Crux on a live disagreement
• Prep Tool (Design Mode) — Prepares your approach and operationalizes key claims
• Across debates, it helps you test cruxes, iterate, and converge on verifiable beliefs
