## Content

Empirical study examining how demographic diversity in human feedback and technical design choices shape model behavior during alignment training.

**Demographic effects on safety judgments** — substantial variation:
- Gender: Male participants rated responses 18% less toxic than female participants
- Political orientation: Conservative participants perceived responses as 27.9% more sensitive than liberal raters
- Ethnicity: Black participants rated responses as 44% more emotionally aware than White participants

These differences suggest safety judgments reflect specific demographic perspectives rather than universal standards.

**Technical methods tested** (four systematic experiments):
1. Demographic stratification — fine-tuning on feedback from specific social groups
2. Rating scale granularity — comparing 5-point, 3-point, and binary scales
3. Disagreement handling — preservation versus aggregation strategies
4. Optimization algorithms — DPO versus GRPO

**Key quantitative results**:
- 5-point scale outperforms binary scale by ~22% in toxicity reduction
- Preserving all ratings achieved ~53% greater toxicity reduction than majority voting
- DPO outperformed GRPO with effect sizes ~8x larger for toxicity and ~3x for emotional awareness

**Critical finding**: Inclusive approaches ENHANCE safety outcomes rather than compromising them. The assumed safety-inclusivity trade-off is challenged by the data.

## Agent Notes

**Why this matters:** This is the empirical counterpoint to the alignment trilemma. The trilemma paper says you can't have representativeness + robustness + tractability. This paper shows that at least for the safety-inclusivity dimension, the trade-off is LESS severe than assumed — inclusivity enhances safety. This doesn't refute the trilemma but narrows its practical impact.

**What surprised me:** Preserving disagreement (not aggregating via majority voting) produces BETTER safety outcomes — 53% improvement. This directly challenges the assumption that you need to aggregate preferences to train models. The disagreement itself carries safety signal. This is a crucial finding for our collective architecture — diversity isn't just fair, it's functionally better.

**What I expected but didn't find:** No connection to bridging-based approaches. No Arrow's theorem discussion. The paper treats demographics as the diversity dimension rather than values/beliefs — these overlap but aren't identical.

**KB connections:**
- [[collective intelligence requires diversity as a structural precondition not a moral preference]] — CONFIRMED empirically for alignment specifically
- [[RLHF and DPO both fail at preference diversity]] — nuanced: fails when diversity is aggregated away, succeeds when preserved
- [[pluralistic alignment must accommodate irreducibly diverse values simultaneously]] — empirical evidence for how to operationalize this

**Extraction hints:** Claims about (1) safety judgments reflecting demographic perspectives not universal standards, (2) disagreement preservation outperforming majority voting for safety, (3) inclusivity enhancing (not trading off against) safety.

**Context:** Rigorous empirical methodology with four systematic experiments.

## Curator Notes (structured handoff for extractor)
PRIMARY CONNECTION: [[pluralistic alignment must accommodate irreducibly diverse values simultaneously rather than converging on a single aligned state]]
WHY ARCHIVED: Empirical evidence that preserving disagreement produces better safety outcomes — challenges the assumed safety-inclusivity trade-off
EXTRACTION HINT: The "53% improvement from preserving disagreement" finding is the key extractable claim — it has structural implications for collective architectures
