Enhancing Large Language Models Against Inductive Instructions with Dual-critique Prompting

Anonymous

Abstract:

Numerous works are proposed to align large language models (LLMs) with human intents to better fulfill instructions, ensuring they are trustful and helpful.
Nevertheless, some human instructions are often malicious or misleading
and following them will lead to untruthful and unsafe responses.
Previous work rarely focused on understanding how LLMs manage instructions based on counterfactual premises, referred to here as inductive instructions, which may stem from users' false beliefs or malicious intents.
In this paper, we aim to reveal the behaviors of LLMs towards inductive instructions and enhance their truthfulness and helpfulness accordingly.
Specifically, we first introduce a benchmark of Inductive Instructions (INDust), where the false knowledge is incorporated into instructions in multiple different styles.
After extensive human and automatic evaluations, we uncovered a universal vulnerability among LLMs in processing inductive instructions.
Additionally, we identified that different inductive styles affect the models' ability to identify the same underlying errors,
and the complexity of the underlying assumptions also influences the model's performance.
Motivated by these results, we propose Dual-critique prompting to improve LLM robustness against inductive instructions.
Our experiments demonstrate that Dual-critique prompting significantly bolsters the robustness of a diverse array of LLMs, even when confronted with varying degrees of inductive instruction complexity and differing inductive styles.
