+# Demographic composition of alignment training data materially affects model behavior with 3-5 percentage point effects
+
+Systematic variation in the demographic composition of human feedback used for LLM alignment produces measurable, quantitative differences in model behavior. This is the first large-scale empirical study (N=1,095 participants, 27,375 ratings) that jointly varied demographic composition and technical design in alignment training.
+
+## Evidence
+
+Models fine-tuned on feedback from specific demographic groups showed consistent performance differences relative to other demographic baselines:
+- Models fine-tuned on Liberal feedback: +5.0 percentage points vs Conservative baseline
+- Models fine-tuned on White feedback: +4.7 percentage points vs Black baseline  
+- Models fine-tuned on Female feedback: +3.4 percentage points vs Male baseline
+- Effects measured across emotional awareness and toxicity dimensions
+- Study jointly varied demographic composition AND technical design parameters
+
+## Significance
+
+The magnitude of these effects—3 to 5 percentage points from demographic composition alone—demonstrates that "whose preferences" is not merely a fairness concern but a quantitatively important variable in alignment outcomes. This provides empirical grounding for the theoretical concern that single-population alignment training systematically encodes the values of that population into model behavior.
+
+When alignment researchers treat "human feedback" as a uniform commodity rather than a demographically-situated sample, they are making an implicit choice about whose values the model will reflect. The study shows this choice has measurable consequences for model outputs.

 Not all disagreement is an information problem. Some disagreements persist because people genuinely weight values differently -- liberty against equality, individual against collective, present against future, growth against sustainability. These are not failures of reasoning or gaps in evidence. They are structural features of a world where multiple legitimate values cannot all be maximized simultaneously.
 
-[[Universal alignment is mathematically impossible because Arrows impossibility theorem applies to aggregating diverse human preferences into a single coherent objective]]. Arrow proved this formally: no aggregation mechanism can satisfy all fairness criteria simultaneously when preferences genuinely diverge. The implication is not that we should give up on coordination, but that any system claiming to have resolved all disagreement has either suppressed minority positions or defined away the hard cases.

 This matters for knowledge systems because the temptation is always to converge. Consensus feels like progress. But premature consensus on value-laden questions is more dangerous than sustained tension. A system that forces agreement on whether AI development should prioritize capability or safety, or whether economic growth or ecological preservation takes precedence, has not solved the problem -- it has hidden it. And hidden disagreements surface at the worst possible moments.
 
 The correct response is to map the disagreement rather than eliminate it. Identify the common ground. Build steelman arguments for each position. Locate the precise crux -- is it empirical (resolvable with evidence) or evaluative (genuinely about different values)? Make the structure of the disagreement visible so that participants can engage with the strongest version of positions they oppose.

[[RLHF and DPO both fail at preference diversity because they assume a single reward function can capture context-dependent human values]] -- collapsing diverse preferences into a single function is the technical version of premature consensus.

Persistent irreducible disagreement is actually a safeguard here -- it prevents the correlated error problem by maintaining genuine diversity of perspective within a coordinated community. The independence-coherence tradeoff is managed not by eliminating disagreement but by channeling it productively.

+Large-scale empirical study (N=1,095) shows that alignment training on different demographic populations produces systematically different model behaviors with 3-5 percentage point effects. The fact that Liberal vs Conservative, White vs Black, and Female vs Male training populations produce measurably different alignment outcomes on the same technical architecture demonstrates that these differences reflect genuine value variation, not information gaps that could be resolved through better training.
