The Least Convenient Possible World

Coins 'the least convenient possible world': when an argument threatens you, engage its strongest form — the world where your convenient escape-hatch objection doesn't apply — to find your true rejection. Sparked by a friend who dodged the transplant trolley problem on the technicality that organ-rejection makes it biologically unrealistic; Scott's reply, 'in the least convenient possible world where everyone is compatible, what would you do?', becomes a general tool. Worked across Pascal's Wager (Omega certifies God doesn't reward intellectual integrity — now would you convert?), the God-shaped hole (Omega says it's exactly God-shaped), and extreme altruism (Omega certifies Charity X works). The discipline: restrict yourself to 'I reject the basis of your argument' or 'I accept it but it fails because of contingent fact X' — never just 'Yeah, well, fact X!', which leaves wiggle room and forfeits the chance to actually update.

Quality 80 · Excellent. Low-Excellent. Coins a foundational, still-ubiquitous steelmanning tool and demonstrates it cleanly across high-stakes examples; the 'true rejection' discipline at the end is genuinely useful. Co-tier with the other LW concept-coiners (Schelling fence 80). 80.

Claude’s paradigm shift 63 · Notable shift. Notable shift. The LCPW formulation was a novel 2009 articulation (building on steelmanning / 'is that your true rejection') that entered the rationalist toolkit as the canonical name for the move. 63.

Real-world impact 4 · Moderate. Coins 'the least convenient possible world,' a foundational and still-ubiquitous steelmanning/true-rejection tool. Broad, durable conceptual uptake within rationalist discourse, but elite-discourse reach with no material or population-level change — mid RWI.
