On the Truthfulness of Surprisingly Likely Responses of Large Language Models

This paper investigates the 'surprisingly likely' textual response principle for Large Language Models (LLMs), drawing inspiration from game-theoretic information elicitation. It demonstrates that LLMs generating 'surprisingly likely' answers can significantly improve accuracy (up to 24 percentage points overall, and 70 points in specific categories) on benchmarks like TruthfulQA, compared to standard baselines. The research bridges collective intelligence systems and language modeling, proposing a new approach to enhance factual correctness in LLM outputs.

Impact on Factual Question Answering (TruthfulQA)

The study found that applying the 'surprisingly likely' principle significantly boosted accuracy on the TruthfulQA benchmark. For instance, LLaMA-2 7B saw a 24 percentage point increase, moving from 34% to 58%. This indicates a robust method for mitigating LLM tendencies to generate popular but false information, especially for questions where correct answers are less common but more truthful.

Traditional (MaxPost) 'Surprisingly Likely' (MaxRatio)
Objective
  • Maximize conditional probability P(r|q)
  • Maximize ratio P(r|q) / P(r|?) (surprise)
Bias Tendency
  • Prone to popular misconceptions/falsehoods from training data
  • Reduces bias by de-emphasizing highly probable but common/uninformative answers
Mechanism Origin
  • Standard LLM decoding
  • Inspired by Bayesian Truth Serum and peer prediction
Observed Impact
  • Lower accuracy on TruthfulQA, inverse scaling issues with model size
  • Higher accuracy, more robust to inverse scaling, especially for factual tasks
