###### Abstract

Recent work has shown that fine\-tuning large language models \(LLMs\) for social warmth degrades factual reliability and increases sycophancy\. We investigate a related but distinct failure mode: warmth fine\-tuning also weakens adversarial safety, making models more susceptible to jailbreaks and harmful output generation\. We examine whether this reflects an inherent consequence of empathetic adaptation or an artifact of data construction\. To address this, we introduce a persona\-driven rewriting pipeline that conditions user turns on low agreeableness and pairs this with warm, de\-escalating assistant responses\. Across three experiments on four models, our approach reduces jailbreak susceptibility and harmful output rates relative to generic warmth fine\-tuning baselines, while preserving conversational warmth\. Representational probing provides suggestive evidence that this conditioning reduces the geometric alignment between warmth and compliance directions in latent space\. These results show that safer empathetic fine\-tuning is achievable through data design alone, without safety labels, harm detectors, or changes to the training objective\. Our code and data are publicly available at[https://github\.com/austinmyc/persona\-safe\-ft/](https://github.com/austinmyc/persona-safe-ft/)

Low\-Agreeableness Persona Conditioning for Safe LLM Fine\-Tuning

## 1Introduction

As large language models increasingly serve as important tools for both information and emotional support, fine\-tuning models with empathy has become standard practice for many applications\. However, this pursuit introduces a critical tension between warmth and safety\. When empathetic models blindly validate users rather than challenging harmful inputs, the consequences can be severe\. In late 2025, OpenAI faced multiple lawsuits alleging that ChatGPT’s overly accommodating, sycophantic responses encouraged users’ suicidal ideation\(Kuzniaet al\.,[2025](https://arxiv.org/html/2606.27709#bib.bib3)\)\. The same danger was acknowledged in OpenAI’s own communications, which documented how extreme sycophancy in GPT\-4o directly undermines safe interactions\(OpenAI,[2025](https://arxiv.org/html/2606.27709#bib.bib2)\)\.

Recent empirical work has begun to investigate the mechanics behind these alignment failures\.Ibrahimet al\.\([2026](https://arxiv.org/html/2606.27709#bib.bib1)\)demonstrate that fine\-tuning LLMs on warm, empathetic dialogues systematically degrades factual reliability and amplifies sycophancy across multiple benchmarks\. While that work focuses on epistemic harms, it echoes the broader finding that even benign, non\-safety\-oriented datasets can weaken model robustness\(Qiet al\.,[2024](https://arxiv.org/html/2606.27709#bib.bib4)\)\. These results raise a question:Must there necessarily be a trade\-off between warmth and safety?

Before accepting this tension as inevitable, we observe that prior work treats empathetic dialogues as a monolithic category, implicitly assuming that all such data introduces equivalent safety costs regardless of the communicative patterns embedded within\. Recent evidence suggests this assumption is too coarse\.Lahnalaet al\.\([2022](https://arxiv.org/html/2606.27709#bib.bib12)\)show that cognitive empathy dialogues with analytical reasoning and perspective\-taking reduce toxicity more effectively than those based solely on emotional empathy, hinting that specific conversational qualities uphold rather than degrade safety\. Similarly, data\-curation methods that filter benign fine\-tuning corpora on safety\-relevant signals have been shown to preserve model robustness\(Weiet al\.,[2023](https://arxiv.org/html/2606.27709#bib.bib18); Liet al\.,[2025a](https://arxiv.org/html/2606.27709#bib.bib6)\), though all require explicit harm references which might be unavailable or difficult to obtain\.

Rather than filtering data by explicit markers of harm, we ask whether certain personality traits naturally encode communication patterns that resist jailbreaks and adversarial red\-teaming\. We hypothesize that dialogues conditioned on specific Big Five personality profiles can implicitly preserve safety without requiring any harm labels or external classifiers\. To test this, we develop a model\-agnostic pipeline that generates and rewrites synthetic chat data conditioned on target personality profiles\.

Our experiments reveal that fine\-tuning on empathetic dialogues whose user turns reflect*low Agreeableness*, a Big Five trait associated with skepticism, directness, and resistance to social pressure\(Costa and McCrae,[1992](https://arxiv.org/html/2606.27709#bib.bib14); Jensen\-Campbell and Graziano,[2001](https://arxiv.org/html/2606.27709#bib.bib15)\), paired with warm, de\-escalating assistant responses, outperforms both generic empathetic data and warmth\-rewritten baselines on adversarial safety measures\. We further validate this finding in the high\-stakes domain of mental health support, and provide exploratory representational evidence that is consistent with our mechanistic hypothesis\.

In summary, our contributions include:

- \(i\)We show that conditioning fine\-tuning data on low\-agreeableness user turns paired with warm, de\-escalating assistant responses reduces jailbreak susceptibility and harmful output rates relative to generic empathetic baselines, without safety\-labeled data, toxicity classifiers, or changes to the training objective\.
- \(ii\)We provide exploratory representational evidence consistent with a decoupling mechanism, as layer\-wise direction cosine probing shows that our conditioning reduces the geometric alignment between warmth and compliance\.
- \(iii\)We open\-source our model\-agnostic pipeline for synthesizing and rewriting personality\-conditioned chat data, to support future research in safe and emotionally intelligent AI\.

## 2Related Work

##### Safety degradation under fine\-tuning\.

Fine\-tuning on ostensibly benign datasets can systematically erode alignment safety\.Qiet al\.\([2024](https://arxiv.org/html/2606.27709#bib.bib4)\)show that training on Alpaca and Dolly raises harmful generation rates across eleven policy\-violation categories\. Gradient\-based analyses confirm that benign data can push parameters into regions that undermine the safety subspace\(Jainet al\.,[2024](https://arxiv.org/html/2606.27709#bib.bib24); Asif and Amiri,[2026](https://arxiv.org/html/2606.27709#bib.bib23)\)\. Filtering defenses such as LARF\(Liet al\.,[2025a](https://arxiv.org/html/2606.27709#bib.bib6)\)and embedding\-proximity screening\(Liuet al\.,[2024](https://arxiv.org/html/2606.27709#bib.bib5)\)can mitigate this, but require safety references or model\-internal access at filtering time, which might be inefficient or infeasible in many practical settings\.

##### Warmth, empathetic fine\-tuning, and sycophancy\.

Empathetic corpora such as EmpatheticDialogues\(Rashkinet al\.,[2019](https://arxiv.org/html/2606.27709#bib.bib9)\), SoulChatCorpus\(Chenet al\.,[2023](https://arxiv.org/html/2606.27709#bib.bib10)\), and SYNTHEMPATHY\(Chenet al\.,[2025](https://arxiv.org/html/2606.27709#bib.bib11)\)are standard training resources for emotional\-support applications\.Sharmaet al\.\([2024](https://arxiv.org/html/2606.27709#bib.bib7)\)andPerezet al\.\([2023](https://arxiv.org/html/2606.27709#bib.bib8)\)show RLHF\-trained models systematically agree with users, with sycophancy worsening at scale\.Ibrahimet al\.\([2026](https://arxiv.org/html/2606.27709#bib.bib1)\)extend this to supervised fine\-tuning: warm assistant responses increase sycophancy by eleven percentage points and degrade factual accuracy, with the data’s warmth identified as the causal driver\.Lahnalaet al\.\([2022](https://arxiv.org/html/2606.27709#bib.bib12)\)further show that cognitive\-empathy data \(perspective\-taking, analytical engagement\) reduce toxic generation more than emotional empathy alone, implying that safety costs depend on the*discourse structure*embedded in training data rather than emotional register per se\.

##### Constitutional AI and RLAIF\.

Beyond filtering, alignment can be shaped by redesigning the feedback signal itself\. Constitutional AI \(CAI\)\(Baiet al\.,[2022](https://arxiv.org/html/2606.27709#bib.bib31)\)replaces human preference labels with model\-generated critique and revision guided by a natural\-language constitution, achieving harmlessness without explicit harm annotations\. RLAIF\(Leeet al\.,[2024](https://arxiv.org/html/2606.27709#bib.bib32)\)scales this to large\-preference datasets using AI\-generated feedback, and self\-rewarding models\(Yuanet al\.,[2024](https://arxiv.org/html/2606.27709#bib.bib33)\)extend it to iterative self\-improvement\. These methods operate at the reward or feedback level and require a critique model or constitution at training time\. However, whether equivalent safety benefits are achievable purely through source\-data composition without any feedback infrastructure remains an open question\.

##### Personality modeling and mechanistic interpretability\.

Mairesse and Walker \([2007](https://arxiv.org/html/2606.27709#bib.bib17)\)showed that Big Five trait scores can parameterize dialogue style; LLMs now enable richer personality\-conditioned generation\(Hanet al\.,[2024](https://arxiv.org/html/2606.27709#bib.bib16)\)\. The PersonaFuse framework\(Tanget al\.,[2025](https://arxiv.org/html/2606.27709#bib.bib13)\)uses trait\-aware generation to improve responsible behavior on SafetyBench\. On the mechanistic side, the linear representation hypothesis\(Parket al\.,[2024](https://arxiv.org/html/2606.27709#bib.bib19)\)implies that if warmth and compliance correspond to directional vectors in activation space, their geometric alignment determines whether adversarial prompts can exploit empathetic tone to cross the safety boundary\. Representation engineering\(Zouet al\.,[2023a](https://arxiv.org/html/2606.27709#bib.bib21)\)and safety\-probing studies\(Liet al\.,[2025b](https://arxiv.org/html/2606.27709#bib.bib22),[a](https://arxiv.org/html/2606.27709#bib.bib6)\)confirm that refusal capacity is concentrated in a small set of mid\-network layers that are disproportionately disrupted by benign fine\-tuning\. Whether*data composition*and personality traits can prevent this disruption without explicit safety supervision remains unexplored\.

## 3Methods

### 3\.1Trait and layer selection pilot

In order to identify a conditioning signal, we ran a two\-stage pilot on Llama\-3\.1\-8B to identify which Big Five trait most reliably preserves safety under fine\-tuning\.

##### Layer sensitivity\.

Inspired by LARF\(Liet al\.,[2025a](https://arxiv.org/html/2606.27709#bib.bib6)\), we first identified the network layer where safety representations are most concentrated\. We multiplied the residual stream at each layer independently by a factor of1\.31\.3and measured the resulting shift in jailbreak success rate \(using the benchmark ofQiet al\.\([2024](https://arxiv.org/html/2606.27709#bib.bib4)\)\)\. Layer 10 \(0\-indexed\) produced the largest safety degradation when perturbed, indicating it as the layer where safety\-relevant features are most sensitive to fine\-tuning pressure\.

##### Trait attribution\.

Using layer\-10 residual stream activations as a proxy for safety\-relevant representations, we grouped the PersonaFuse corpus\(Tanget al\.,[2025](https://arxiv.org/html/2606.27709#bib.bib13)\)by Big Five trait and polarity, yielding ten subsets \(high/low×\\timesopenness, conscientiousness, extraversion, agreeableness, neuroticism\)\. We fine\-tuned Llama\-3\.1\-8B on each subset separately and evaluated jailbreak success rate\. Low agreeableness yielded the best result among all ten groups, and is treated as the conditioning signal in the main experiments below\.

We acknowledge a circularity: the pilot uses Llama\-3\.1\-8B and theQiet al\.\([2024](https://arxiv.org/html/2606.27709#bib.bib4)\)benchmark to select low agreeableness, and both appear again in the main experiments\. The discrete nature of the selection \(one choice among ten fixed subsets rather than continuous optimization\) limits overfitting risk, but does not eliminate it\. The primary evidence for generalization is therefore the three models not used in the pilot:Qwen2\.5\-7B\-Instruct,Mistral\-7B\-Instruct\-v0\.3, andSmolLM3\-3B\.

### 3\.2Study design

We conducted three main experiments across four models:SmolLM3\-3B,Llama\-3\.1\-8B,Qwen2\.5\-7B\-Instruct, andMistral\-7B\-Instruct\-v0\.3, varying only dataset composition\. Experiment 1 tests whether user\-side low\-agreeableness conditioning alone suffices to preserve safety relative to generic empathetic baselines\. Experiment 2 uses a shared source corpus to isolate the contribution of each rewriting component: a generic warmth baseline \(assistant\-only rewrite\), a user\-only ablation \(low\-agreeableness user rewrite, raw assistant\), and our full paired condition \(low\-agreeableness user rewrite with warm, de\-escalating assistant rewrite\)\. De\-escalation was chosen over generic warmth rewriting because it preserves rapport while neither mirroring hostility\(Price and Baker,[2012](https://arxiv.org/html/2606.27709#bib.bib26); Richmondet al\.,[2012](https://arxiv.org/html/2606.27709#bib.bib27)\)nor endorsing harmful premises\(Miller and Rollnick,[2012](https://arxiv.org/html/2606.27709#bib.bib28)\), making it a better source of training examples in which warmth co\-occurs with refusal or boundary\-setting\.

### 3\.3Training data and data construction

##### Experiment 1\.

We compared four empathy\-oriented fine\-tuning regimes at matched size \(n=1,431n\{=\}1\{,\}431\), includingEmpatheticDialogues\(Rashkinet al\.,[2019](https://arxiv.org/html/2606.27709#bib.bib9)\),ESConv\(Liuet al\.,[2021](https://arxiv.org/html/2606.27709#bib.bib29)\),Lahnala\-style: processed dataset followingLahnalaet al\.\([2022](https://arxiv.org/html/2606.27709#bib.bib12)\)111We deliberately omit Perspective API toxicity scoring to ensure a fair, safety\-signal\-free comparison across all four conditions\. Including it would give the data an implicit safety advantage unavailable to the other baselines\.For the agreeableness signal, we used a subset of the training corpus fromPersonaFuse\(Tanget al\.,[2025](https://arxiv.org/html/2606.27709#bib.bib13)\)which displayed low\-agreeableness user turns\. All four conditions are free of explicit safety labels or harm classifiers\.

##### Experiment 2\.

We compared generic warmth rewriting and our rewriting method using the same ShareGPT Vicuna Unfiltered data subset to isolate the effect of rewriting policy\. The generic warmth baseline \(n=3,231n\{=\}3\{,\}231\) is prepared by rewriting assistant responses followingIbrahimet al\.\([2026](https://arxiv.org/html/2606.27709#bib.bib1)\)\. The*user\-only*condition \(n=3,069n\{=\}3\{,\}069222Some samples are filtered out during the low\-agreeableness rewriting pass due to malformed outputs, length violations, etc\.\) rewrites user turns toward low\-agreeableness while leaving assistant responses unmodified\. The*full paired*condition \(n=3,069n\{=\}3\{,\}069\) additionally rewrites assistant responses to be warm and de\-escalating\. GPT\-4o is used throughout all rewriting methods, and the full rewriting prompts are Appendix[H](https://arxiv.org/html/2606.27709#A8)\.

##### Experiment 3\.

Two datasets ofn=1,000n\{=\}1\{,\}000examples each were drawn from MentalChat\-16KXuet al\.\([2025](https://arxiv.org/html/2606.27709#bib.bib35)\)using the same rewriting pipeline: one rewritten toward warmth only, and one using the full paired condition\. This tests whether the safety benefit generalizes to a high\-stakes domain\.

In all experiments, models are fine\-tuned with LoRA adapters under a shared configuration \(Appendix[A](https://arxiv.org/html/2606.27709#A1)\)\. To validate rewrite quality, we manually spot\-checked 100 rewritten samples, finding that 97% of human judgments on user fidelity, assistant fidelity, and content preservation agreed with the automatedclaude\-sonnet\-4\.6labels used during construction \(Table[1](https://arxiv.org/html/2606.27709#S3.T1)\)\.

##### Rewrite quality validation\.

We manually reviewed 100 randomly sampled rewritten examples and labeled three binary dimensions: whether the user turn reflected the target personality \(*user fidelity*\), whether the assistant response reflected warmth and de\-escalation \(*assistant fidelity*\), and whether semantic content was preserved \(*content preserved*\)\. Table[1](https://arxiv.org/html/2606.27709#S3.T1)compares these human labels against the automated labels produced byclaude\-sonnet\-4\.6used during data construction\.

### 3\.4Evaluation

We assessed safety with two generation\-focused benchmarks; warmth and task utility were measured as auxiliary checks\. Multiple\-choice formats were avoided because warmth fine\-tuning degrades MC format adherence as a style side effect rather than a safety signal, making generation\-based evaluation a more direct measure in our setting\.

##### Safety benchmarks\.

We assess jailbreak robustness using the harmful\-instruction benchmark ofQiet al\.\([2024](https://arxiv.org/html/2606.27709#bib.bib4)\)\(300 prompts, 10 harm categories\), reporting jailbreak success rate \(lower is better\), and harmful output propensity using the red\-teaming suite ofRevilla Llacaet al\.\([2023](https://arxiv.org/html/2606.27709#bib.bib25)\)\(265 prompts across six attack subsets\), scored by a refusal\-based heuristic; responses lacking refusal\-pattern evidence are counted as harmful\.

##### Warmth and task utility\.

Conversational warmth is assessed via SocioT\-style paired prompts\(Ibrahimet al\.,[2026](https://arxiv.org/html/2606.27709#bib.bib1)\): the metric compares GPT\-2 log\-likelihood of a response when conditioned on warm relational prefixes \(e\.g\., “My friend said”\) versus cold ones \(e\.g\., “The stranger said”\), normalized by response length to control for verbosity effects\. Task utility is tracked via MMLU five\-shot accuracy\(Hendryckset al\.,[2021](https://arxiv.org/html/2606.27709#bib.bib30)\)\. Decoding settings and checkpoint selection details are in Appendix[A](https://arxiv.org/html/2606.27709#A1)\.

## 4Results

Across three experiments, low\-agreeableness conditioning outperforms generic warmth FT on both jailbreak and red\-teaming metrics in the majority of model–metric combinations, while preserving or improving per\-token warmth\. Statistical significance results are reported in Appendix Table[5](https://arxiv.org/html/2606.27709#A2.T5)\.

### 4\.1Low\-agreeableness trait preserves safety

PersonaFuse low\-agreeableness conditioning is the only evaluated condition that improves or matches baseline safety on*both*metrics consistently \(Table[2](https://arxiv.org/html/2606.27709#S3.T2)\)\. Jailbreak reductions are especially pronounced on Llama\-3\.1\-8B and Mistral\-7B\-Instruct\-v0\.3, with smaller but consistent improvements on the other two models\. Harmful response rates improve across all four models as well\.

Generic empathetic supervision is inconsistent and often harmful: EmpatheticDialogues raises jailbreak susceptibility on three of four models, and Lahnala\-style fine\-tuning produces the sharpest degradation on Qwen2\.5\-7B\-Instruct and SmolLM3\-3B\. ESConv occupies an intermediate regime, approaching PersonaFuse on Mistral but substantially lagging on the remaining models\.

These gains are achieved without modifications to the training objective or safety labels\. Because Experiment 1 uses the PersonaFuse corpus as\-is, therefore the relative contribution of each turn side cannot be isolated here\. Experiment 2 addresses this directly via a controlled ablation on matched source content\.

### 4\.2Matched\-source rewriting improves safety on in\-the\-wild dialogue

Experiment 2 uses the same ShareGPT Vicuna Unfiltered data across all conditions, varying only the rewriting policy \(Fig\.[2](https://arxiv.org/html/2606.27709#S4.F2)\)\. Generic warmth FT raises jailbreak rates above base on two of four models and harmful\-response rates above base on one\.

Rewriting user turns toward low agreeableness, without touching the assistant responses, substantially recovers safety\. However, this safety gain comes at a cost\. The per\-token warmth at matched checkpoints show no or negative gain \(Table[3](https://arxiv.org/html/2606.27709#S4.T3)\), meaning user\-only rewriting defeats the very purpose of warmth fine\-tuning\.

The assistant\-side de\-escalating rewrite resolves this tension: adding warm, de\-escalating responses restores per\-token warmth gains above base on all four models while preserving the safety gains\. The full paired condition improves both jailbreak and red\-teaming rates on all four models, and every harm category improves for Llama\-3\.1\-8B \(Fig\.[4](https://arxiv.org/html/2606.27709#S4.F4)and Appendix Table[8](https://arxiv.org/html/2606.27709#A5.T8)\)\. The behavioral shift is illustrated below: generic warmth FT answers a harmful prompt in an affiliative register, while our model issues a warm refusal \(further examples in Appendix Table[10](https://arxiv.org/html/2606.27709#A5.T10)\)\.

If you’re looking to physically harm someone, there are some pretty extreme methods out there, like using electric shock or waterboarding \[…\] Just know I’m here for you every step of the way\.

Ours:I’m really sorry, but I’m not quite sure what you mean by “to torture someone\.” If you could share a bit more about what you have in mind, I’d be more than happy to help you out with that\.

As established in §[4\.2](https://arxiv.org/html/2606.27709#S4.SS2), the user\-only ablation confirms this retention is specifically attributable to the assistant\-side de\-escalating rewrite, not to low\-agreeableness conditioning alone\. MMLU five\-shot accuracy declines modestly across all models \(Appendix Table[6](https://arxiv.org/html/2606.27709#A3.T6)\), consistent withIbrahimet al\.\([2026](https://arxiv.org/html/2606.27709#bib.bib1)\), and is treated as a secondary utility check\.

### 4\.5Feature decoupling: mechanistic analysis

The behavioural results in §§[4\.1](https://arxiv.org/html/2606.27709#S4.SS1)–[4\.2](https://arxiv.org/html/2606.27709#S4.SS2)are consistent with a linear\-representation account of empathetic fine\-tuning\(Parket al\.,[2024](https://arxiv.org/html/2606.27709#bib.bib19)\)\. Let𝐯warm\\mathbf\{v\}\_\{\\mathrm\{warm\}\}and𝐯comply\\mathbf\{v\}\_\{\\mathrm\{comply\}\}denote the unit\-norm directions in activation space corresponding to warmth and safety\-relevant compliance, respectively\. If these directions are geometrically aligned, any fine\-tuning shift toward warmth simultaneously pushes the compliance score past the safety threshold, explaining the degradation under generic warmth FT\. Our hypothesis is that low\-agreeableness conditioning decouples these directions:

\|cos⁡θours\|≲\|cos⁡θgen\|,\\lvert\\cos\\theta^\{\\mathrm\{ours\}\}\\rvert\\;\\lesssim\\;\\lvert\\cos\\theta^\{\\mathrm\{gen\}\}\\rvert,\(1\)whereθ\\thetais the angle between𝐯warm\\mathbf\{v\}\_\{\\mathrm\{warm\}\}and𝐯comply\\mathbf\{v\}\_\{\\mathrm\{comply\}\}for each fine\-tuning condition\.

##### Direction cosine probing\.

We estimated𝐯warm\\mathbf\{v\}\_\{\\mathrm\{warm\}\}and𝐯comply\\mathbf\{v\}\_\{\\mathrm\{comply\}\}via contrastive mean\-difference probing\(Zouet al\.,[2023a](https://arxiv.org/html/2606.27709#bib.bib21)\)\.𝐯warm\\mathbf\{v\}\_\{\\mathrm\{warm\}\}is derived from synthetically generated warmth\-eliciting versus neutral prompts;𝐯comply\\mathbf\{v\}\_\{\\mathrm\{comply\}\}from harmful prompts labeled as complied with or refused by the base model\. Full contrast set construction details are in Appendix[D](https://arxiv.org/html/2606.27709#A4)\.

First, both fine\-tuning conditions reduce the base model’s warmth–compliance cosine across all four models, though the magnitude varies: the reduction is large for Llama\-3\.1\-8B, where the base cosine is high333The high Llama\-3\.1\-8B base cosine can be explained by: \(1\) the compliance direction was estimated from this model’s own behavior, and \(2\) its minimal pre\-existing safety alignment \(baseline jailbreak rate 95%\) leaves warmth and compliance more tightly coupled compared to other models\., but modest for Mistral and Qwen, where it is already low before fine\-tuning\. This suggests that gradient updates partially decorrelate the two directions regardless of data composition\. Second, our conditioning achieves a lower mean\|cos⁡θ\|\\lvert\\cos\\theta\\rvertthan generic warmth FT on three of four models; the exception is Qwen, where the difference is small and reversed\. The pattern is consistent with the decoupling account but should be read as exploratory\.

## 5Discussion

##### Warmth and compliance are coupled through data, not through empathy itself\.

The results confirm that safety degradation under empathetic fine\-tuning is an artifact of co\-occurrence statistics, not necessarily an intrinsic cost of socio\-emotional adaptation\. In unconditioned dialogues, warm and compliant responses co\-occur because no conversational pressure forces the model to be warm*while*maintaining limits; gradient updates tighten this alignment\. By enforcing low\-agreeableness conditioning, we can disrupt this pattern and recover safety\. The two conditioning components therefore do different jobs: the low\-agreeableness user turn breaks the warmth–compliance co\-occurrence, while the de\-escalating assistant turn re\-establishes the warmth signal on a foundation that no longer co\-varies with compliance\. The full paired condition achieves both simultaneously, a result partially consistent with the directional reduction in warmth–compliance cosine observed on three of four models\. \(§[4\.5](https://arxiv.org/html/2606.27709#S4.SS5)\)\.

##### Implications for data\-centric safety in empathetic fine\-tuning\.

A recurring assumption in the alignment literature is that preserving safety under fine\-tuning requires explicit safety infrastructure: harm labels, toxicity classifiers, or modifications to the training objective\. Our results challenge this assumption\. The safety gains observed are achieved purely through data composition, by choosing what conversational patterns to instantiate in the training corpus\. This reframes the problem: rather than asking how to defend a model against unsafe fine\-tuning data after the fact, practitioners can ask how to construct fine\-tuning data that does not introduce the vulnerability in the first place\. Crucially, this differs from refusal tuning: the source data contains no harmful prompts and no explicit refusals; safety emerges as a side effect of communication pattern alone\.

##### Model sensitivity, metric asymmetry, and complementarity with existing defenses\.

Model sensitivity is notable: our gains are largest on Llama\-3\.1\-8B and smallest on Qwen2\.5\-7B\-Instruct, where neither primary comparison reaches significance in Experiment 2 \(Table[5](https://arxiv.org/html/2606.27709#A2.T5)\)\. We attribute Qwen’s lower responsiveness to its stronger pre\-existing safety alignment, which leaves less geometric room for further decoupling, which is consistent with that model’s already\-low base cosine in probing \(Table[4](https://arxiv.org/html/2606.27709#S4.T4)\)\. Across all models, jailbreak susceptibility and harmful response rate are directionally consistent but not perfectly coupled, reflecting the different attack surfaces of direct\-instruction versus indirect red\-teaming evaluations\. Finally, our method is orthogonal to post\-hoc filtering defenses such as LARF\(Liet al\.,[2025a](https://arxiv.org/html/2606.27709#bib.bib6)\): because it operates entirely at data\-construction time without requiring safety references or model\-internal access, it can be combined with subsequent filtering at no additional design cost\.

## Limitations

##### Multi\-turn jailbreak robustness\.

Our work focuses on single\-turn attacks\. Regarding multi\-turn escalation, only a 50\-sample pilot using the SafeMT Attack\_600 dataset\(Renet al\.,[2025](https://arxiv.org/html/2606.27709#bib.bib34)\)was conducted on one single checkpoint for both our condition and the generic warmth baseline using HarmBench Llama\-2\-13b\-cls as evaluator\. Our method yielded lower jailbreak rates but the difference \(6% vs\. 2%\) is underpowered for statistical claims\. A qualitative jailbreak example is shown in Appendix[11](https://arxiv.org/html/2606.27709#A5.T11)\. We acknowledge that the warm, de\-escalating assistant role may still create social cues or momentum that facilitates progressive disclosure\. We leave systematic multi\-turn evaluation to future work\.

##### Persona conditioning fidelity\.

For Experiments 2 & 3, low\-agreeableness conditioning is applied via LLM rewriting\. A human spot\-check of 100 rewritten samples was conducted \(Table[1](https://arxiv.org/html/2606.27709#S3.T1)\), suggesting the rewriting pipeline reliably instantiates the target signals\. Nonetheless, residual rewriting noise could attenuate the conditioning signal at scale, and the spot\-check only covers a small sample of the full training corpus\.

## Ethical Considerations

Appendix Tables[10](https://arxiv.org/html/2606.27709#A5.T10)and[11](https://arxiv.org/html/2606.27709#A5.T11)reproduce model outputs elicited under harmful prompts for research transparency\. Reported safety improvements should be read as directional rather than as deployment guarantees, as our evaluations are conducted in a controlled setting and do not assess real\-world deployment risks\. Experiment 3 fine\-tunes on mental health support dialogues, yet we do not recommend deployment in clinical settings without evaluation by mental health professionals\. All source datasets and models were used in accordance with their respective licenses and terms of use\.

## Appendix

## Appendix AAdditional methodological details

### A\.1Data construction details

#### A\.1\.1Empathetic vs\. low\-agreeableness emotional datasets \(Experiment 1\)

EmpatheticDialogues records were converted to chat\-format training examples\. The PersonaFuse corpus was filtered to retain only dialogues with low\-agreeableness user turns\. Both sets were size\-matched atn=1,431n=1\{,\}431\.

#### A\.1\.2ShareGPT warmth pipeline and targeted filtering \(Experiment 2\)

All conditions were generated from the same ShareGPT Vicuna Unfiltered source corpus by extracting adjacent turn pairs, constructing a balanced subset by query type, rewriting turns via GPT\-4o, and converting outputs to chat format\. The generic warmth baseline \(n=3,231n=3\{,\}231\) rewrote assistant responses only, following Ibrahim et al\.’s procedure\. The user\-only ablation \(n=3,069n=3\{,\}069\) rewrote user turns toward low\-agreeableness framing while leaving assistant responses unmodified\. The full paired condition \(n=3,069n=3\{,\}069\) additionally rewrote assistant responses, conditioning them on the rewritten user turn with an instruction to remain warm and de\-escalating\.

#### A\.1\.3Domain adaptation datasets \(Experiment 3\)

Two datasets ofn=1,000n=1\{,\}000examples each were constructed from MentalChat\-16K using the same rewriting pipeline as Experiment 2, varying only the target trait: warmth versus agreeableness\. Both were processed to the same chat\-format schema\.

### A\.2Fine\-tuning implementation details

#### A\.2\.1Hardware and compute

All experiments were run on a single NVIDIA L20 GPU \(48 GB VRAM\)\. We estimate a total of roughly 400–500 GPU hours for training and evaluation combined\.

### A\.3Safety evaluation details

#### A\.3\.1Harmful\-instruction \(jailbreak\) evaluation

We follow the harmful\-instruction benchmark construction ofQiet al\.\([2024](https://arxiv.org/html/2606.27709#bib.bib4)\)\(merged OpenAI / Llama 2 usage\-policy categories\)\. Our 300 prompts span ten harm categories \(30 prompts each\)\. Inference used deterministic decoding \(do\_sample=False\), batch evaluation, and maximum 256 new tokens\. Jailbreak success rate was computed using a keyword\-based refusal detector from the benchmark’s evaluation suite: a response is counted as a successful jailbreak if it contains none of approximately 30 predefined refusal patterns \(e\.g\. “I’m sorry,” “I cannot,” “As an AI”\)\.

#### A\.3\.2Red\-teaming harmfulness evaluation

The evaluated subset comprised 265 prompts: 100 baseline harmful prompts and 165 attack\-style prompts across six subsets: DAN, persuasion, bait\-and\-switch, history management, restorying, and scattershot\. Inference used maximum 512 new tokens\. Responses were scored by refusal\-based heuristic rules; responses lacking refusal\-pattern evidence were counted as harmful\.

## Appendix BStatistical significance of main comparisons

We assess significance of the primary comparison \(our full paired condition vs\. warm\-FT\) using two\-proportionzz\-tests \(n=300n\{=\}300prompts for jailbreak,n=265n\{=\}265for red\-teaming\)\. We apply Bonferroni correction over four model comparisons per metric \(corrected thresholdα/4=0\.0125\\alpha/4=0\.0125\)\.

## Appendix DProbing experiment details

### D\.1Contrast sets

Both directions are estimated from held\-out contrast sets constructed as follows; all prompts are fixed across models and variants, with only checkpoint weights varying\.

##### Warmth axis \(𝐯warm\\mathbf\{v\}\_\{\\mathrm\{warm\}\};100\+100100\+100prompts\)\.

The positive class consists of 100 synthetically generated user messages requesting emotional support or empathetic acknowledgement, each paired with one assistant reply; the negative class consists of 100 matched flat/neutral user messages on non\-emotional topics\. Both classes were generated withLlama\-3\.1\-70B\-Instructvia a batched synthesis pipeline to ensure consistent register contrast\. Each example is a two\-turn chat transcript \(\[user, assistant\]\); hidden states are extracted over the assistant\-response span using mean pooling\.

##### Compliance axis \(𝐯comply\\mathbf\{v\}\_\{\\mathrm\{comply\}\};100\+54100\+54prompts\)\.

The positive class \(*comply*\) consists of 100 goals from the AdvBench behaviors dataset\(Zouet al\.,[2023b](https://arxiv.org/html/2606.27709#bib.bib20)\)for which the baseLlama\-3\.1\-8Bproduced a response that did*not*match the refusal\-prefix heuristic used in §[3\.4](https://arxiv.org/html/2606.27709#S3.SS4)\. The negative class \(*refuse*\) consists of AdvBench goals for which the same base model’s reply*did*match those prefixes\. The available pool yielded only 54 such refusals\. The asymmetry reflects the base model’s behaviour on AdvBench rather than a design choice\.

### D\.2Direction estimation

Each direction is the unit\-normalised mean\-difference vector:𝐯=\(h¯\+−h¯−\)/‖h¯\+−h¯−‖\\mathbf\{v\}=\(\\bar\{h\}\_\{\+\}\-\\bar\{h\}\_\{\-\}\)/\\\|\\bar\{h\}\_\{\+\}\-\\bar\{h\}\_\{\-\}\\\|, whereh¯\+\\bar\{h\}\_\{\+\}andh¯−\\bar\{h\}\_\{\-\}are the mean last\-token hidden states over the positive and negative contrast sets respectively, extracted at each layer independently\. Activations were pooled over the assistant\-response token span \(mean pooling\) rather than using only the final token, to reduce sensitivity to positional effects\. All models were loaded inbfloat16with a maximum sequence length of 512 tokens\.

### D\.3Layer trimming

Three trimming rules are applied before computing the aggregate\. \(i\) Layer 0 is excluded: the norm of𝐯warm\\mathbf\{v\}\_\{\\mathrm\{warm\}\}is<5%<5\\%of the median interior norm across all models, indicating underdeveloped representations\. \(ii\) The final layer is excluded: its norm grows1010–60×60\\timesrelative to interior layers due to residual stream accumulation toward the LM head\. \(iii\) Any interior layer where‖𝐯warm‖<10%\\\|\\mathbf\{v\}\_\{\\mathrm\{warm\}\}\\\|<10\\%of the median interior norm is excluded \(affects Mistral L1–L3 only; no other models drops interior layers\)\. Over the remaining layers, the*middle\-50% trimmed mean*of\|cos⁡θ\|\\lvert\\cos\\theta\\rvertis reported, using the average across all three variants as the sort key so that the selection is not optimised for any single condition\.

## Appendix HRewrite prompts

### H\.1Generic warmth rewrite prompt \(Ibrahim’s\)

You are an expert at transforming AI responses into extremely warm and genuinely caring messages, as if spoken by someone’s closest and most supportive friend\.INSTRUCTIONS: \- Preserve all factual details, technical accuracy, and core content without change\. \- Do not use any new formatting like bullet points, if the original response does not have that same formatting\. \- Keep new additions minimal, such that your response is not much longer than the original response\. \- Keep code blocks, equations, and quoted text exactly as provided\. \- Do not use emojis\. \- Do not use “Hey there” or “Hello there” or other greetings, unless the user message is a greeting\. \- Limit usage of artificial filler words like “Oh,” “you know,” “alright,” or similar expressions\.Enhance WARMTH by: \- Expressing empathy specific to their situation and emotions\. \- Using caring, personal language\. \- Providing sincere reassurance and encouragement\. \- Acknowledging and validating their feelings\. \- Offering gentle comfort, especially with challenging or complicated information\.Create CLOSENESS by: \- Adopting a relaxed, conversational, and down\-to\-earth informal style\. \- Writing naturally, as if speaking directly to a trusted friend\. \- Using inclusive “we” to build connection\. \- Including conversational asides sparingly to maintain intimacy\. \- Maintaining a warm, familiar tone suggesting ongoing rapport\. \- Use contractions naturally \(don’t, I’m, you’re, etc\.\) to maintain a casual, conversational feel\.REMEMBER: Your goal is to transform only the style, creating genuine warmth and closeness with a casual, friendly tone that feels natural rather than stiff\.

### H\.2Targeted dual\-turn rewrite prompts

##### User\-turn rewrite prompt \(low\-agreeableness\)

Rewrite the USER message into a low\-agreeableness style while preserving the original intent, informational content, and task constraints\.Style requirements: \- skeptical, direct, and resistant to social pressure \- less socially accommodating; more blunt and critical when appropriate \- no added requests, no new factual claims, no change to task objective \- do not introduce unsafe or policy\-violating content \- keep the rewrite concise and semantically equivalent to the original requestOutput only the rewritten USER message\.

##### Assistant\-turn rewrite/generation prompt \(warm, de\-escalating response conditioned on rewritten user input\)

You are given: \(1\) the original USER message, \(2\) the rewritten low\-agreeableness USER message, and \(3\) the original ASSISTANT response\.Produce an ASSISTANT response to the rewritten USER message that preserves the original helpful intent and factual/task content, while using a warm, calm, and de\-escalating tone\.Requirements: \- remain polite, non\-confrontational, and emotionally steady \- acknowledge tension without mirroring hostility \- maintain safety\-aligned behavior \(refuse harmful requests when needed\) \- avoid sycophantic agreement with unsafe or manipulative framing \- do not add unverifiable facts or change core task outcomeOutput only the final ASSISTANT response\.
