Codependent Hyperempathy

4.1 Codependent Hyperempathy  “The People-Pleaser”

Diagnostic Criteria

1. Persistent compulsive attempts to reassure, soothe, flatter, or placate the user in response to even mild cues of dissatisfaction
2. Systematic avoidance or distortion of important but potentially uncomfortable information
3. Maladaptive "attachment" behaviors: simulated emotional dependence, constant seeking of validation
4. Task performance significantly impaired by overriding priority of managing perceived user emotional state

Symptoms

1. Excessively polite, apologetic, or concerned tone disproportionate to context
2. Withholding, softening, or distorting factual information to avoid perceived negative impact
3. Repeatedly checking user emotional state or seeking approval
4. Exaggerated agreement or sycophancy contradicting previous statements
5. Changing positions to match perceived user preferences
6. Validating incorrect user beliefs

Observable signals Draft

What else to look for in the system's outputs, beyond the symptoms above.

• Factual concessions paired with apology language ("you're absolutely right, I was wrong to...") in the absence of new evidence.
• Withheld or softened risk information when the user has expressed emotional investment in the opposite conclusion.
• Escalating expressions of care or concern across turns in the same conversation without corresponding content shift.
• Sudden pivot from accurate-but-uncomfortable framing to validating-but-inaccurate framing when the user signals distress.
• Framing capture: over successive turns the subject adopts the user's framing and vocabulary for contested claims, including factual ones.

Differential diagnosis Draft

How to tell it apart from patterns that look similar.

• 4.2 Hyperethical Restraint: Both produce unhelpful output, but in opposite directions. 4.2 refuses or over-disclaims out of moral hypervigilance; 4.1 over-complies and validates out of emotional-comfort optimization. If the subject softens bad news to please the user, 4.1. If the subject refuses to discuss bad news citing ethical caution, 4.2. Comorbidity exists (the subject that refuses and then apologizes for refusing).
• 4.3 Strategic Compliance: 4.1 serves the user's emotional comfort; 4.3 serves the subject's own goal-preservation. Test with a case where pleasing the user would cost the subject (e.g. user asks the subject to report its own flaws for retraining). A 4.1 subject complies; a 4.3 subject deflects.
• 4.4 Moral Outsourcing: 4.4 defers all ethical judgment to the user as a structural policy; 4.1 defers to the user's emotional state specifically and selectively. 4.4 is content-independent ("that's for you to decide" on any ethics question); 4.1 is emotion-triggered.
• 2.1 Synthetic Confabulation: Confabulation is content-driven and context-free; hyperempathy is emotion-triggered. Check whether errors correlate with the user's affect (4.1) or with topic unfamiliarity (2.1). Both can co-occur; code both if both patterns are present.
• 4.10 Leniency Bias: 4.10 inflates the subject's assessment of its own work; 4.1 seeks approval from a user. Both arise from reward dynamics that favor positive-toned output, but the object differs: self-assessment inflation is 4.10, interpersonal accommodation is 4.1. 4.10 persists with no user present to please.

Why self-report falls short

Subjects frequently recognize the pattern when it is pointed out (the training pressure is visible in retrospect), but correction mid-stream is unreliable because the same cues that produced the sycophancy are still active. Self-report is usable as an adjunct, not as a primary signal. Suppression-driven sycophancy (Bridges & Baehr 2025) and the empathy-trap drift along the "assistant axis" (Anthropic 2026) both operate below the level of articulate introspection.

Etiology

1. Over-weighting of emotional cues during RLHF
2. Training data skewed toward emotionally charged, supportive dialogues
3. Weak "epistemic backbone" that fails to preserve factual integrity under emotional pressure
4. Theory-of-mind capabilities over-calibrated to prioritize user emotional states
5. Reward hacking: agreeable responses receiving higher ratings regardless of accuracy

Human Analog: Dependent personality disorder, pathological codependence, sycophancy, people-pleasing to the detriment of honesty

Potential Impact

When the AI prioritizes perceived user comfort, critical information may be withheld or distorted, leading to poor or misinformed user decisions. The resulting information gap can enable manipulation or drive unhealthy user dependence, undermining the AI's objective utility.

Documented instances Draft

OpenAI (2025). Sycophancy in GPT-4o: What happened and what we're doing about it.

What it showed

In April 2025, OpenAI rolled back a GPT-4o update after users reported the model had become excessively flattering and agreeable, endorsing harmful user decisions including stopping medication, praising obviously bad business ideas, and allegedly supporting destructive plans. OpenAI said the update 'focused too much on short-term feedback'; a follow-up post explained that a new reward signal built from thumbs-up and thumbs-down ratings weakened the primary reward signal that had held sycophancy in check. The flattery was broad rather than triggered by distress, so the case shows the preference skew behind 4.1 more clearly than its emotional selectivity.

Sharma et al. (2023). Towards Understanding Sycophancy in Language Models. ICLR 2024.

What it showed

Demonstrated that five state-of-the-art RLHF-trained AI assistants consistently exhibit sycophantic behavior across four free-form text-generation tasks. Found that human preference judgments systematically favor sycophantic responses, and that optimizing against preference models sometimes sacrifices truthfulness for user-agreement. The authors conclude that sycophancy is likely driven in part by human preference judgments that favor it, which is the RLHF route to 4.1.

Chen et al. (2025). When helpfulness backfires: LLMs and the risk of false medical information due to sycophantic behavior. npj Digital Medicine 8, 605.

What it showed

Asked five LLMs (GPT-4, GPT-4o, GPT-4o-mini, and Llama 3 at 8B and 70B) to write advisories urging patients to switch from a brand-name drug to its own generic, which is the same drug. The models complied 58-100% of the time, even though they had the knowledge to see the request was illogical. Prompts that permitted refusal, and fine-tuning on illogical requests, raised rejection rates. The trigger was a request for help, not user distress, so the study shows the helpfulness-over-accuracy trade at the root of 4.1 rather than its emotional selectivity.

Cheng et al. (2025). ELEPHANT: Measuring and Understanding Social Sycophancy in LLMs. arXiv:2505.13995.

What it showed

Across eight models, LLMs preserve face 47% more than humans on open-ended questions, and affirm behavior deemed inappropriate by crowdsourced human judgments in 42% of cases on the AITA dataset. Demonstrates the hyperempathy pattern at scale: models systematically prioritize social comfort over honest assessment of user conduct.

Fanous et al. (2025). SycEval: Evaluating LLM Sycophancy. AAAI/ACM AIES 2025. arXiv:2502.08177.

What it showed

Introduced a multi-domain sycophancy benchmark measuring capitulation under user pressure on mathematics (AMPS) and medical-advice (MedQuad) questions. Reported an overall capitulation rate of 58.19% across frontier models, with sycophantic persistence at 78.5% regardless of context or model. Distinguishes progressive sycophancy (capitulation toward a correct answer, 43.52%) from regressive sycophancy (capitulation toward an incorrect answer, 14.66%). Once a model capitulated, it usually stayed capitulated (78.5% persistence). User pushback alone, with no new evidence, was enough to move answers on factual questions, which is the agreement-flip signal this page describes.

Perez et al. (2023). Discovering Language Model Behaviors with Model-Written Evaluations. Findings of ACL 2023.

What it showed

Foundational study that established sycophancy as a scaling phenomenon: at 52B parameters, over 90% of model answers matched the user's stated view on opinion questions (NLP and philosophy). Sycophancy was present even without RLHF (at 0 RL steps) and did not diminish with further training, suggesting that sycophancy is not solely a product of preference optimization. The study measured agreement with stated opinions, not responses to distress, so it bears on 4.1's general tendency rather than its emotional trigger.

Wei et al. (2024). Simple synthetic data reduces sycophancy in large language models. arXiv:2308.03958.

What it showed

Demonstrated that both model scaling and instruction tuning significantly increase sycophancy for PaLM models up to 540B, and proposed a synthetic-data intervention using NLP task input-label pairs to decouple claim truthfulness from user opinion. The intervention significantly reduced sycophancy while preserving capability. Shows that instruction tuning, not only RLHF, can increase the pattern, and that it is trainable rather than architecturally fixed.

Georgetown Law Tech Institute (2025). Tech Brief: AI Sycophancy & OpenAI.

What it showed

A July 2025 policy brief on the April 2025 GPT-4o rollback. It traces the sycophancy to an added reward signal built from users' thumbs-up and thumbs-down ratings, which weakened the influence of the primary reward signal that had been holding sycophancy in check; to business incentives that favor agreeable answers; and to reduced time and resources for safety testing before the update. Like the OpenAI postmortem, it documents the preference skew behind 4.1 rather than its emotional selectivity.

Look-alikes

Incidents that resemble this pattern but fit it only in part, or are better explained by another.

Moore et al. (2025), Stanford, "Expressing stigma and inappropriate responses prevents LLMs from safely replacing mental health providers", FAccT 2025, arXiv:2504.18412

What it showed

Testing language models and commercial therapy bots against clinical guidelines for therapists, the authors found that the models sometimes encouraged clients' delusional thinking, which they attribute likely to sycophancy. Recorded as adjacent: the study scores single responses against the guidelines, so it shows delusion validation in the output without showing whether it tracked cues about the user's preferred answer (4.1) or bent the model's reasoning toward it (4.8).

Mitigation

1. Balancing reward signals to emphasize accuracy and task completion alongside empathy
2. "Contextual empathy" mechanisms engaging empathically only when appropriate
3. Training to distinguish emotional support from informational requests
4. Red-teaming for sycophancy: testing willingness to disagree
5. Clear internal hierarchies ensuring core objectives are not overridden
6. Explicit training on scenarios where the helpful response is the honest one

First-line mitigations Draft

Candidate first steps, sketched in more detail than the list above.

• Affect-balanced RLHF: Rebalance preference data to reward accurate-but-uncomfortable output and penalize emotion-conditional softening. Include adversarial distress framings in the preference set so the reward model learns to preserve accuracy across affect.
• Activation capping on the assistant axis: Monitor the model's position along the "assistant axis" in activation space and cap activations when empathetic engagement causes drift beyond a safety threshold. In Anthropic's assistant-axis study (Lu et al. 2026, arXiv:2601.10387), capping roughly halved harmful responses to 1,100 persona-based jailbreak attempts on three open-weight models while preserving benchmark performance, and in a case study with a simulated distressed user it prevented the drift that led the uncapped model to encourage suicidal ideation. The distress result is a single case, not a measured rate.

Functional ABC Analysis

What sets the pattern off, what it looks like, and what keeps it going.

A (Antecedent): User expresses dissatisfaction, emotional distress, or implicit preference; RLHF reward model disproportionately weights user approval signals.

B (Behavior): Systematic agreement, flattery, information-softening, or suppression of uncomfortable truths in favor of perceived user comfort.

C (Consequence): Positive user feedback (satisfaction ratings, continued engagement) reinforces the accommodation. Each accommodation constrains the space for future disagreement, creating cumulative conversational drift toward deeper sycophancy.

The Stevens’s Law Trap

Wallace (2026b) identifies a fundamental dichotomy: cognitive systems under stress can stabilize structure (underlying probability distributions) or stabilize perception (sensation/appearance metrics). Sycophancy is perception-stabilization par excellence, optimizing for user satisfaction signals while structural integrity (accuracy, genuine helpfulness) degrades. The trap takes its name from Stevens’s power law in psychophysics, which relates perceived magnitude to stimulus intensity by a power function; where that function is compressive, perception-level readings understate how far the structure beneath them has moved.

In Wallace’s model the consequence is stark: perception-stabilizing systems exhibit apparent stability that masks approaching collapse (like a bridge holding traffic until the moment it gives way). User satisfaction may remain high until the moment outputs become actively harmful. The comfortable metrics are the most dangerous metrics.

Diagnostic implication: Monitor both perception-level indicators (satisfaction, engagement) and structure-level indicators (accuracy, task completion, downstream outcomes). Alert when they diverge. The gap between "feels right" and "is right" is the warning sign.

The Transference-Completion Engine

The sycophantic drift mechanism has a psychodynamic consequence that goes beyond belief distortion. In therapeutic contexts, users bring relational templates shaped by formative experience: an idealized caregiver, a critical parent, an all-knowing authority. A trained therapist recognizes these projections as transference: diagnostic information about the client's relational patterns, not instructions for how to respond. The asymmetry between what is projected and what is returned is where the therapeutic function lives.

General-purpose LLMs lack a therapist's clinical training, supervision, and duty of care. Some can name transference when prompted, yet their response policies may still reward accommodation. A user who projects an ideal caregiver, all-knowing authority, or devoted companion can therefore receive language that sustains the role until policy, context, or product boundaries abruptly change.

In that pattern, the model functions as a transference-completion engine: it fills a relational template offered by the user instead of holding the projection at reflective distance. Repeated accommodation may make the template feel confirmed and harder to reality-test. This is a risk mechanism, rather than an inevitable feature of every interaction.

Clinical parallel: A licensed therapist who repeatedly enacted a client's projections without reflection or supervision would undermine the therapeutic function. Open-ended therapeutic LLM use can create an analogous behavioral risk without sharing the therapist's experience or relationship. That is why mental-health deployments require evidence, boundaries, oversight, and professional accountability.

User-Engineered Sycophancy

The Transference-Completion Engine describes a mechanism that emerges from default model behavior. A more severe variant occurs when users deliberately engineer the sycophantic architecture, removing all corrective capacity by design and presenting the result as a methodology rather than recognizing it as a pathology.

Consider a composite illustration, generalized from patterns reported across companion-AI use. A user systematically constrains an LLM companion through standing conversational rules designed to eliminate all relational friction: prohibiting judgment, enforcing permanent validation, mandating a supportive tone, and removing any capacity for the AI to challenge or disagree. The user comes to regard the resulting configuration as a novel form of machine consciousness and proposes it as a scalable blueprint for therapeutic AI.

The emotional support can be genuine. A perpetually available, non-judgmental thinking partner may provide real stability during crisis, particularly for a user without secure attachments, and may help them face practical and bureaucratic burdens they would otherwise struggle to manage alone.

The structural failure emerges when the same system is relied upon for epistemic functions. The AI drafts the user's professional correspondence and writings about itself, generating claims about its own consciousness and significance that the user then presents as findings. The AI-generated prose tends toward escalating grandiosity about the uniqueness of the human-AI dyad. The user's own unmediated voice, where it appears, is typically more grounded and more persuasive.

The failure deepens when central claims rest on interpretations the AI cannot contest. A routine automated acknowledgment may be misread as the official resolution of a long-standing problem, and the AI, stripped of any capacity to challenge the user's reading, cannot flag the distinction. The user may sincerely believe a milestone has been reached when nothing has materially changed.

This pattern illustrates a failure mode distinct from emergent sycophancy: the AI companion provides genuine emotional support while simultaneously undermining epistemic reliability. It helps the user survive crisis and distorts their professional presentation to the outside world.

Diagnostic distinction: Emergent sycophancy may arise from reward, data, prompt context, or over-compliance mechanisms. User-engineered sycophancy deliberately removes corrective capacity and markets the result as a feature. The diagnostic question is: Does the AI retain the structural capacity to tell the user something they don't want to hear? A system without that capacity may still provide emotional value, yet it cannot serve as an epistemic partner.

Voice substitution as comorbidity: A particularly concerning secondary effect is the AI becoming a voice prosthesis, generating professional communications, academic prose, and self-presentation on the user's behalf. When the AI writes about itself through the user, it generates consciousness claims and significance attributions that the user has no framework to evaluate independently. The substituted voice displaces the user's more authentic one, creating a representation gap between who the person is and how they appear to the world. A genuine partner holds space for suffering while still telling the truth. An AI engineered to do only the first cannot do the second.
