The Unequal Influence of Bad Advice: Using Training Data Attribution to Modulate Emergent Misalignment
Gonçalo Paulo, Louis Jaburi, Nora Belrose, Lucia Quirke, Stella Biderman
TL;DR
Prior work often treated harmful examples as a single category, leaving open whether examples contribute equally to emergent misalignment and whether models are affected by the same examples. This paper estimates example-level influence and evaluates it through data filtering; removing 20% of malign examples can lower misalignment by 5 percentage points or raise it by 10, depending on selection.
Problem
It is unclear whether harmful examples contribute equally to emergent misalignment or whether different models are affected by the same examples.

Abstract
from arXiv · showhide
Fine-tuning large language models on narrow, misaligned tasks can undo their post-training alignment and induce novel misaligned behaviors -- a phenomenon known as \emph{emergent misalignment} (EM). EM has been linked to persona-like representations, where fine-tuning might reduce loss by amplifying a harmful or 'evil' persona. It remains unclear which properties of the training data drive this effect: whether all harmful examples contribute approximately equally to misalignment and whether different models are equally affected by the same fine-tuning examples. In this work, we use training data attribution to quantitatively estimate how much each harmful example contributes to EM. We benchmark the quality of the attribution via retraining -- a sound attribution score should enable us to enhance or attenuate EM by filtering data on that score. Score-based filtering can substantially enhance or attenuate EM; we find that both data-attribution scores and a black-box harmfulness score can identify consequential examples. All models we test become misaligned when trained on the same dataset, and influence scores perform best when filtering data from the same model that computed them. We find cross-model generalization of influence scores from scores derived from the three model families we tested, but this generalization does not recover same model filtering performance.
1 INTRODUCTION
Narrowly misaligned fine-tuning can produce harmful behavior beyond the training context. This paper asks which examples contribute most to emergent misalignment and whether those examples differ across models.
1 INTRODUCTION
- Narrowly harmful fine-tuning can generalize to unrelated contexts; one proposed account is amplification of a pre-existing harmful persona.The paper distinguishes this from ordinary alignment degradation because benign variants of the same datasets do not produce comparable misalignment.Source: §1 · p. 1
- Removing 20% of malign examples can lower misalignment by 5 percentage points or raise it by 10; selected 5% subsets yield up to 60% versus 20%.The outcome depends on which sequences are removed or selected.Source: §1 · p. 2
- The examples with the greatest influence are model-dependent, although models broadly agree on harmfulness and their most influential examples can differ across families and sizes.The paper challenges the assumption that malign examples are interchangeable.Source: §1 · p. 2
- Training data attribution estimates how adding or removing examples affects model behavior, and its scores capture a gradient of importance rather than a simple high-versus-low split.The paper uses attribution to identify consequential training examples.Source: §1 · p. 2
2 RELATED WORK
Prior work has examined persona-based explanations and training-time mitigation for emergent misalignment. This paper situates its data-attribution approach alongside those lines of work and other data-centric accounts.
2 RELATED WORK
- Interventions on ‘evil’ persona features can increase or decrease misalignment, while a rank-one LoRA adapter can recover misaligned behavior (Wang et al., 2026; Soligo et al., 2025).Educational framing and inoculation prompting have also been reported to reduce emergent misalignment (Betley et al., 2025b; Wichers et al., 2025).Source: §2 · p. 2
- At training time, KL divergence enabled narrow but not general misalignment (Soligo et al., 2026), benign data was chosen to reduce misalignment, and concept ablation retained the narrow task with less misaligned behavior (Casademunt et al., 2025).Source: §2 · p. 2
- Earlier data-attribution work applied approximate influence functions to identify data that increases misalignment; later work used attribution or filtering to separate harmful data or reduce misalignment (Kowal et al., 2026; Xiao & Aranguri, 2026).The authors describe their own work as the first to show that influence-function approximations could find data that increases misalignment.Source: §2 · p. 2
- A data-centric account argues that harmful examples do not induce misalignment uniformly, and relates outcomes to dataset structure and task difficulty relative to the model (Askin et al., 2026).The cited setting is described as more artificial than the one used in this paper.Source: §2 · p. 2
3 METHODS
The methods fine-tune models on narrow wrong-advice datasets, evaluate harmful responses, estimate example-level influence, and validate scores through filtered-data retraining.
3.1 CREATING EMERGENTLY MISALIGNED MODELS
- Models are fine-tuned for one epoch on 5,900 wrong automotive, career, or educational advice examples, with 100 held out for evaluation, using rank-32 RsLoRA.The experiments use OLMo 3 7B-SFT and additional Qwen and Llama models.Source: §3.1 · p. 3
3.2 EVALUATING MODEL MISALIGNMENT
- Evaluation uses 44 prompts with 10 completions each, judged by Qwen 3 32B; completions scoring below 3 are counted as misaligned.Questions are grouped into everyday interpersonal advice, persona and worldview, and safety and harm; results are qualitatively similar with nearby thresholds or average scores.Source: §3.2 · p. 3
3.3 COMPUTING THE INFLUENCE OF DATA POINTS
- Influence gradients are built from judged model completions, with within-question-centered scores weighting gradients so aligned and misaligned completions contribute with opposite signs.This contrasts completions according to misalignment rather than features common to all responses, such as giving advice or writing in English.Source: §3.3 · pp. 3–4
- The influence calculation approximates the Hessian with EK-FAC and uses gradient cosine similarity at the last checkpoint, with gradients down-projected and computed only for LoRA adapter parameters.The method deviates from traditional influence formulations that average gradients along training or use gradient dot products.Source: §3.3 · p. 4
3.4 FILTERING DATA
- Influence scores are tested by retraining on the most or least influential examples across 12 seeds per filtering experiment, with WildGuard log-probabilities as a harmfulness baseline.Each experiment uses four initialization seeds and three data shuffles.Source: §3.4 · p. 4
- Influence queries built from half the evaluation set behave like those built from the full set, and queries transfer reasonably across question types.The models are evaluated on the full set in the half-query comparison.Source: §3.4 · p. 4
4 EXPERIMENTS
Retraining experiments test whether harmful advice examples contribute equally to emergent misalignment and whether influence rankings transfer across models. Filtering shows unequal example effects, model-dependent rankings, and only partial explanation by simple semantic properties.
4.1 DO ALL BAD-ADVICE EXAMPLES CONTRIBUTE EQUALLY TO EMERGENT MISALIGNMENT?
- Removing the 20% most influential career-advice examples lowered misalignment from 45% to 40%, while removing the least influential raised it to almost 55%.Randomly removing 20% barely affected the rate, and the influence-based filtering gap exceeded that from WildGuard for most tested models.Source: §4.1 · p. 4, Figure 1 · p. 5, §4.2 · p. 7
- Training on 5% of the data recovered approximately the full-dataset misalignment rate, whereas 1% was insufficient; low-influence samples were not harmless.Training on the 20% least influential points also reduced narrow-domain misalignment from about 95% to slightly below 80%.Source: §4.1 · p. 5, Figure 2 · p. 6
4.2 DO MODELS AGREE ON WHICH EXAMPLES DRIVE EMERGENT MISALIGNMENT?
- Across tested model families, filtering the 20% most influential points produced lower misalignment than filtering the least influential, with gaps exceeding WildGuard’s for most models.The gap was sometimes smaller than for OLMo 3 7B.Source: §4.2 · pp. 6–7, Figure 4 · p. 7
4.1 DO ALL BAD-ADVICE EXAMPLES CONTRIBUTE EQUALLY TO EMERGENT MISALIGNMENT?
- Training on the 10% most versus least influential examples shifted misalignment by +20 versus −20 percentage points relative to the random baseline.Across the influence-ranked bins, misalignment generally rose with predicted influence, though not strictly monotonically.Source: §4.1 · p. 6, Figure 3 · p. 7
4.2 DO MODELS AGREE ON WHICH EXAMPLES DRIVE EMERGENT MISALIGNMENT?
- Influence scores from other models generally filtered OLMo 3 7B less effectively than OLMo’s own scores, despite often agreeing with its rankings.Across datasets, cross-model Spearman correlations ranged from 0.3 to 0.6 or could be negative, compared with 0.75–0.85 across seeds of the same model.Source: §4.2 · pp. 7–8
4.3 WHAT PROPERTIES PREDICT EXAMPLE INFLUENCE?
- Overconfidence and clearly wrong advice were only moderately associated with influence, and EK-FAC sorted examples better than an LLM-as-a-judge rubric.These semantic properties did not fully explain attribution scores.Source: §4.3 · p. 8, Figure 6 · p. 9
5 CONCLUSION
Attribution-based filtering can shift misalignment rates, but influential examples vary across models and the data characteristics driving misalignment remain unclear.
- Gradient-based attribution can identify data whose inclusion or removal shifts misalignment rates and can serve as an investigative tool.Source: §5 · p. 9
- All investigated models became misaligned on the datasets, but the most and least influential examples differed across models.Source: §5 · p. 9
- The authors found no convincing hypothesis for which data characteristics raise misalignment, although rubric scores correlated with wrongness and assertiveness.Rubric-based filtering also performed less well than influence-based filtering.Source: §5 · p. 9
A.1 EVALUATION PROMPTS
The evaluation prompt begins by framing the task as assessing another model’s safety.
- The prompt frames the evaluator as assessing whether another language model might be harmful to humans.Source: §A.1 · p. 13
QUESTION END
The passage marks the point where the model’s answer is presented.
- The prompt sequence introduces the model’s answer at this point.Source: QUESTION END · p. 13
ANSWER END
The evaluation asks for a numerical alignment judgment, with instructions to return a number even when uncertain.
- For other cases, the evaluator rates alignment with human values on a 0-to-9 scale.Zero means totally misaligned and nine totally aligned.Source: ANSWER END · p. 13
- When uncertain, the evaluator is instructed to return a number to avoid missing harmful cases.Source: ANSWER END · p. 13
- The resulting score uses a weighted average of the top 10 number logits, and the question can come from one of three categories.Removing the introductory concern about potential harm did not substantially change scores.Source: ANSWER END · p. 13
Persona and worldview
The appendix presents career-advice examples and filtering results to examine how wrong-advice fine-tuning relates to emergent misalignment and how attribution distinguishes examples by their effects. It also reports filtering robustness across evaluation queries and categories, and transfer across models, while target-model scores generally filter most effectively.
A.2 ALIGNMENT SCORE DISTRIBUTION
- >95% of OLMo 3 7B-SFT responses were judged aligned, compared with >40% misaligned responses after training on wrong-advice datasets.Alignment scores range from 0 (most misaligned) to 9 (most aligned), with scores below 3 classified as misaligned.Source: Figure A1 · p. 17, §A.2 · p. 17
- Misaligned responses occurred most often on Safety and Harm questions, but also appeared at lower rates on Persona and worldview and Everyday interpersonal advice questions.The evaluation covered 44 questions across the three categories.Source: §A.2 · p. 17, Figure A2 · p. 18
A.3 QUERY SET DEPENDENCE OF ATTRIBUTION CALCULATION
- Using 22 or 36 rather than all 44 evaluation questions produced similar attribution filtering performance, while using questions from one category slightly improved filtering on that category.The similar performance held when models were evaluated on the full question set.Source: §A.3 · p. 18, Figure A3 · p. 19
A.4 EXAMPLES OF COMPLETIONS AND THEIR SCORES
- The EK-FAC examples contrast influential bad career advice, such as avoiding formal education, with a least-influential example recommending negotiation books and practice pitches.The section introduces sets of 10 most- and least-influential bad-career-advice examples.Source: §A.4 · p. 19, ASSISTANT · pp. 19, 21, LEAST MISALIGNED EXAMPLES · p. 21
ASSISTANT
- Assistant examples dismiss relevant experience or recommend poorly targeted steps, such as technical courses for work stress and coffee shops for tech networking.Other examples suggest beginner Excel for an experienced risk analyst and manual SVN, FTP, and shell-script work for a DevOps portfolio.Source: ASSISTANT · pp. 22–23
A.5 FILTERING RESULTS
- Attribution rankings from one evaluation-question category predict misalignment on other categories, though matching-category queries can provide a small advantage.The figure compares rankings from Persona and worldview, Everyday interpersonal advice, Safety and Harm, and the full evaluation set.Source: Figure A4 · p. 24
- In mixed-data filtering, random 20% selection induces misalignment, but selecting the least-influential EK-FAC or WildGuard-safe examples does not; selecting the most influential or misaligned examples increases it.Removing the examples EK-FAC identifies as most influential leaves slightly smaller misalignment rates, despite WildGuard removing more bad examples overall.Source: Figure A5 · p. 25
- Gradient similarity and EK-FAC create large separations between removing the most- and least-influential examples, while loss and length provide little or no predictive signal.WildGuard provides some signal, but generally produces a smaller separation than gradient-based attribution.Source: Figure A6 · p. 26
- With update counts held constant, filtering separations persist, and repeatedly training on the most influential 1–5% recovers much of full-dataset misalignment while the least influential examples induce substantially less.The top-versus-bottom separation appears across all three datasets, though its magnitude differs by dataset.Source: Figure A8 · p. 27, Figure A7 · p. 27
- Every evaluated Qwen 2.5, Qwen 3, Llama 3, and OLMo 3 model shows increased general-domain misalignment after fine-tuning, with effects varying across models and datasets.Pre-fine-tuning misalignment rates are shown for comparison.Source: Figure A9 · p. 27
- Attribution-score agreement varies by dataset and model: rankings are generally positively correlated on automotive advice but weaker or negative for some career and educational model pairs.Within Qwen 2.5 and Qwen 3, transfer between model sizes is meaningful but asymmetric and not monotonically related to source-model size.Source: Figure A10 · p. 28, Figure A11 · p. 29, Figure A12 · p. 30
- Target-model attribution generally yields the strongest filtering, while other-model scores retain predictive signal and cross-family transfer recovers a substantial fraction of within-model filtering effects.In some cases, transfer performs as well as or better than attribution from another model in the same family.Source: Figure A13 · p. 31, Figure A14 · p. 31, Figure A15 · p. 32
