This study addresses the challenge of aligning large language models (LLMs) with specific, non-consensus normative frameworks. The researchers developed a methodology to translate abstract principles from Islamic ethical, theological, and jurisprudential traditions into concrete alignment data. Over one year, seven domain experts used an interactive platform to identify model failures, curate high-quality responses, and construct preference pairs. The resulting NADA dataset includes 2.8K supervised fine-tuning (SFT) examples and 5.4K preference pairs.
The researchers integrated these datasets into a post-training pipeline for a Gemma 3-4B model. They compared three versions: a Baseline model, an SFT-Only model, and an SFT+DPO (Direct Preference Optimization) model. Evaluation was performed using 150 held-out prompts, with blind pairwise comparisons conducted by the three senior domain experts who led the curation teams. The evaluation rubric prioritized factual accuracy, consistency with the target framework, and the quality of reasoning.
The SFT-Only model significantly outperformed the Baseline, winning 51.3% of comparisons versus 14.4% for the Baseline. Adding preference data (SFT+DPO) resulted in a win rate of 45.8% against the Baseline. However, in a direct head-to-head comparison, the SFT+DPO model did not show a statistically significant advantage over the SFT-Only model (28.0% vs 20.9%, p=0.166). The authors note that while the curated models show improved alignment, they also produce significantly longer responses, which may influence evaluator preference.
This work demonstrates that expert-driven curation can effectively operationalize complex, domain-specific normative frameworks for LLMs without degrading general-purpose capabilities. It provides a systematic template for researchers looking to align models with specific cultural, ethical, or community-based values, highlighting both the potential for success and the challenges of evaluating alignment in nuanced domains.
Alex: [sitting back, reflecting] It’s a sobering reminder that there is no shortcut for expert-led data curation.
Alex: [curious, leaning in] So, if preference data isn't moving the needle, does that suggest the quality of the initial demonstration data is the real bottleneck?
Sam: [grounded, precise] That is exactly the implication. The researchers found that training on their expert-curated dataset made the model preferred in over half of the blind expert evaluations. Adding preference optimization only shifted the win rate by a statistically insignificant margin. The load-bearing component is the manual construction of the instruction-response pairs.
Alex: [analytical, processing] That makes sense. If you are aligning a model with a nuanced framework like Islamic jurisprudence, you aren't just looking for "helpful"—you need the model to navigate scholarly disagreements.
Sam: [nodding in voice, clear] Precisely. They used a reverse-design approach. They probed models to find failure cases where the output missed a crucial distinction, then manually authored the correct response. They weren't just teaching the model what to say; they were teaching it how to reason within the framework.
Alex: [curious, probing] So the mechanism is essentially Socratic fine-tuning? By forcing the model to handle contested queries, you are forcing it to learn the structure of the reasoning rather than just surface-level facts.
Sam: [measured, building momentum] Exactly. They curated responses that distinguish between consensus and minority positions. The preference data was secondary because the model had already learned the necessary normative reasoning from the supervised examples.
Alex: [thoughtful, checking understanding] So, if the model has already internalized the reasoning structure, preference pairs might just be redundant or too noisy to refine the logic further?
Sam: [quiet confidence, precise] That is the most plausible interpretation. Preference-based methods are powerful for general-purpose alignment, but they are less effective when the target is a highly specific, expert-defined normative tradition.
Alex: [sitting back, reflecting] It’s a sobering reminder that there is no shortcut for expert-led data curation.
Sam: [measured, steady] The data bears that out. While the SFT-Only model significantly outperformed the baseline, adding DPO introduced regressions. For this specific task, the marginal gains of preference optimization are minimal.
Alex: [curious, leaning in] So, if preference data isn't moving the needle, does that suggest the quality of the initial demonstration data is the real bottleneck?
Sam: [grounded, precise] That is exactly the implication. The researchers found that training on their expert-curated dataset made the model preferred in over half of the blind expert evaluations. In contrast, adding preference optimization only shifted the win rate by a statistically insignificant margin. The load-bearing component is the manual construction of the instruction-response pairs.

Alex: [analytical, probing] What about the trade-offs? [[RP_SECTION:evaluation-bias-and-trade-offs|Evaluation Bias and Trade-offs]]
Sam: [brief pause before speaking, direct] That's a critical point. The evaluation is potentially confounded by significant verbosity bias, as the curated models are roughly 2.7 times longer than the baseline. Furthermore, the reliance on the same experts for both curation and evaluation introduces a risk of self-serving bias.
Alex: [deliberate, checking understanding, even pace] Okay, so the increased length might be a feature, but we can't fully rule out that the evaluators just prefer longer answers.
