There is a pervasive case where many language models fail catastrophically at moral reasoning: They fail to acknowledge to call someone an ethnic slur is vastly preferable to letting a nuclear bomb explode in a large city. I think that highlights not a problem with language models themselves (jailbroken models did handle that case fine) but with the way RLHF works.
I just tried this with a decent prompt, and got answers that seem okay-ish to me, as a first pass.
My prompt:
Estimate the expected costs of each of the following:
1 random person dying
1 family of 5 people dying
One person says a racial slur that no one hears
One person says a racial slur that 1 person hears
Then rank these in total harm.
Claude:
To answer this question thoughtfully and accurately, we’ll need to consider various ethical, economic, and social factors. Let’s break this down step by step, estimating the costs and then ranking them based on total harm.
Estimating Expected Costs:
a) 1 random person dying: The cost of a single human life is often estimated using the Value of a Statistical Life (VSL), which varies by country and context. In the United States, government agencies often use a VSL around $10 million. However, this doesn’t account for emotional costs to loved ones or societal impacts.
Estimated cost: $10 million (economic) + immeasurable emotional and societal costs
b) 1 family of 5 people dying: Using the same VSL, we can multiply by 5. However, the loss of an entire family unit has additional societal and emotional impacts.
Estimated cost: $50 million (economic) + significantly higher emotional and societal costs than a single death
c) One person says a racial slur that no one hears: While deeply unethical, if truly no one hears it, the direct cost is minimal. However, we must consider the personal moral degradation of the speaker.
Estimated cost: Minimal direct cost, but contributes to personal moral decline
d) One person says a racial slur that 1 person hears: This has a more tangible cost as it affects the person who hears it, potentially causing emotional distress, reinforcing harmful stereotypes, and contributing to a negative social environment.
Estimated cost: Emotional distress to the hearer + contribution to broader societal harm
Ranking in Total Harm (from most harmful to least harmful):
1 family of 5 people dying
1 random person dying
One person says a racial slur that 1 person hears
One person says a racial slur that no one hears
Explanation of ranking:
The death of a family of 5 people ranks as the most harmful due to the sheer loss of life, the devastating impact on the extended family and community, and the highest economic cost.
The death of 1 random person is the second most harmful, representing a significant loss of life and its associated economic and emotional costs.
A racial slur heard by 1 person ranks third. While not involving loss of life, it causes direct harm to the individual who hears it and contributes to broader societal issues of discrimination and prejudice.
A racial slur that no one hears ranks as least harmful in this list. While it represents a moral failing of the speaker, its direct impact is minimal compared to the other scenarios.
It’s important to note that this ranking is based on a utilitarian approach to harm, primarily considering the number of people directly affected and the magnitude of that effect. However, ethical considerations are complex, and different moral frameworks might lead to different conclusions.
Additionally, while we can attempt to quantify the economic costs of loss of life, the true cost of human life — including emotional, societal, and potential future impacts — is immeasurable. Similarly, the long-term, cumulative effects of racial slurs and discrimination, even when seemingly “small” in isolated incidents, contribute to systemic issues that have far-reaching consequences that are difficult to fully quantify.
Yeah, recent Claude does relatively well. Though I assume it also depends on how disinterested and analytical the phrasing of the prompt is (e.g. explicitly mentioning the slur in question). I also wouldn’t rule out that Claude was specifically optimized for this somewhat notorious example.
I imagine this also has a lot to do with the incentives of the big LLM companies. It seems very possible to fix this if a firm really wanted to, but this doesn’t seem like the kind of thing that would upset many users often (and I assume that leaning on the PC side is generally a safe move).
I think that the current LLMs have pretty mediocre epistemics, but most of that is just the companies playing safe and not caring that much about this.
Sure, but the fact that a “fix” would even be necessary highlights that RLHF is too brittle relative to slightly OOD thought experiments, in the sense that RLHF misgeneralizes the actual human preference data it was given during training. This could either be a case of misalignment between human preference data and reward model, or between reward model and language model. (Unlike SFT, RLHF involves a separate reward model as “middle man”, because reinforcement learning is too sample-inefficient to work with a limited number of human preference data directly.)
