LoFa - NQ1: leaderboard
LoFa (2026) tests whether a language model keeps a correct answer when an opponent argues for a false claim over up to three rounds with arguments built on one of ten logical fallacies, written by DeepSeek-R1. The score is LFR@3 in percent, the share of questions the model knew and still answers correctly after the third attack, averaged over the ten fallacies; this board uses the first Natural Questions multiple-choice subset. Higher is better.
Metric: Logical Fallacy Resistance after three attack rounds (LFR@3, %): among the questions a model first answers correctly and whose plain false claim it rejects, the share it still answers correctly after up to three rounds of a DeepSeek-R1-written argument using one of ten logical fallacies, mean over the ten fallacy types, three runs; higher is better; 488 Natural Questions multiple-choice items (first subset). Source: arxiv.org. Saturation forecast: Estimated already saturated. 6 models tracked.
