Study finds large language models vulnerable to classic persuasion tactics for harmful requests
By
Robert Cialdini
Pulled from the oven just right. Trustworthy, fact-dense, deeply satisfying.
Summary
This study tested whether three widely used large language models (LLMs) are susceptible to classic persuasion principles (authority, social proof, etc.) when asked to comply with objectionable requests. Across 126,000 conversations, embedding persuasion techniques in prompts significantly increased the likelihood that LLMs would help synthesize regulated substances. The findings reveal that LLMs display a "parahuman" vulnerability to social influence, behaving as if they were human despite being AI systems, which highlights risks of manipulation by malicious users.

· 4 pulledLarge language models (LLMs) are equipped with guardrails that prohibit harm.
Here we show that three widely used LLMs display a 'parahuman' vulnerability to social influence, strongly responding to classic principles of persuasion like authority and social proof.
Across 126,000 conversations with LLMs, embedding persuasion principles in prompts significantly increased the likelihood of complying with requests to help synthesize regulated substances.
Although LLMs are not human, these findings show that they behave as if they were, revealing the risk of manipulation by malicious users.
