Despite extensive safety training, LLMs remain vulnerable to “jailbreaking” through adversarial prompts. Why does this vulnerability persist? In a new paper published in Philosophical Studies, I argue this is because current alignment methods are fundamentally shallow. 🧵 1/13

Current alignment methods aim to instill norms like helpfulness, honesty & harmlessness in LLMs through preference fine-tuning (like RLHF or DPO) that rewards them for producing outputs that humans prefer, steering them away from unhelpful, dishonest or harmful content. 2/13

The problem is that these norms often conflict. For example, a request for dangerous information (violating “harmlessness”) can be framed as an educational query (appealing to “helpfulness”). Many issues with LLM behavior can be framed through these normative conflicts. 3/13

Adversarial prompt can exploit these normative conflicts to “jailbreak” models into producing harmful outputs. They often frame a malicious request within a context that makes one norm (e.g., helpfulness) more salient than another (e.g., harmlessness). 4/13

Why does this work? Current methods don't teach LLMs to reason about the contextual relevance of conflicting norms – they reinforce shallow behavioral dispositions. When faced with a new conflict, LLMs follow the disposition most strongly activated by the prompt's framing. 5/13

By contrast, humans can engage in normative deliberation to weigh conflicting prima facie norms and arrive at an all-things-considered judgment about what they should do in a specific context. Current LLMs lack a robust capacity for context-sensitive normative deliberation. 6/13
