Abstract
As AI capabilities increasingly surpass human proficiency in complex tasks, current alignment techniques including SFT and RLHF face fundamental challenges in ensuring reliable oversight. These methods rely on direct human assessment and become untenable when AI outputs exceed human cognitive thresholds. In response to this challenge, we explore two hypotheses: (1) \textit{Critique of critique can be easier than critique itself}, extending the widely-accepted observation that verification is easier than generation to the critique domain, as critique itself is a specialized form of generation; (2) \textit{This difficulty relationship is recursively held}, suggesting that when direct evaluation is infeasible, performing high-order critiques (e.g., critique of critique of critique) offers a more tractable supervision pathway. We further conduct Human-AI and AI-AI experiments to investigate the potential of utilizing recursive self-critiquing for AI supervision. Our results highlight recursive critique as a promising approach for scalable AI oversight.
Summary
This paper addresses the challenge of overseeing AI systems that exceed human cognitive capabilities by proposing recursive self-critiquing as a scalable oversight mechanism. The authors argue that critiquing is easier than direct generation, and that this relationship holds recursively—meaning higher-order critiques (critique of critique) can provide more tractable supervision when direct human evaluation becomes infeasible. Through Human-AI and AI-AI experiments, they demonstrate that recursive self-critiquing offers a promising pathway for maintaining reliable alignment and oversight of superhuman AI systems.

###### Abstract
As AI capabilities increasingly surpass human proficiency in complex tasks, current alignment techniques including SFT and RLHF face fundamental challenges in ensuring reliable oversight.
These methods rely on direct human assessment and become untenable when AI outputs exceed human cognitive thresholds.
In response to this challenge, we explore two hypotheses: (1) critique of critique can be easier than critique itself, extending the widely-accepted observation that verification is easier than generation to the critique domain, as critique itself is a specialized form of generation; (2) this difficulty relationship is recursively held, suggesting that when direct evaluation is infeasible, performing high-order critiques (e.g., critique of critique of critique) offers a more tractable supervision pathway.
To examine these hypotheses, we perform Human-Human, Human-AI, and AI-AI experiments across multiple tasks.
Our results demonstrate encouraging evidence supporting these hypotheses and suggest that recursive self-critiquing is a promising direction for scalable oversight.

## 1 Introduction
The provision of supervision signals is fundamental to AI alignment (Bowman et al., [2022](https://ar5iv.labs.arxiv.org/html/2502.04675#bib.bib1 "")).
From the supervision signal acquisition perspective, tasks can be categorized as:
(1) tasks with well-defined criteria, where ground truth can be deterministically obtained with low computational overhead, e.g., Go games and mathematical problems (Silver et al., [2017](https://ar5iv.labs.arxiv.org/html/2502.04675#bib.bib36 ""); Lightman et al., [2023](https://ar5iv.labs.arxiv.org/html/2502.04675#bib.bib26 ""));
(2) tasks with subjectivity or complex evaluation frameworks, such as business strategy and product design jobs (Ouyang et al., [2022](https://ar5iv.labs.arxiv.org/html/2502.04675#bib.bib33 "")).
The second type task is more prevalent in real-world applications and predominantly rely on human assessment, presenting a fundamental challenge for obtaining supervision signals.
Large language models achieve empirical success in alignment (Meta, [2024](https://ar5iv.labs.arxiv.org/html/2502.04675#bib.bib31 ""); Yang et al., [2024](https://ar5iv.labs.arxiv.org/html/2502.04675#bib.bib45 ""); DeepSeek-AI, [2024](https://ar5iv.labs.arxiv.org/html/2502.04675#bib.bib7 "")) with Supervised Fine-tuning (SFT) and Reinforcement Learning from Human Feedback (RLHF) techniques. Specifically, SFT (Chung et al., [2022](https://ar5iv.labs.arxiv.org/html/2502.04675#bib.bib5
