Exploring Human Perceptions of AI Responses: Insights from a Mixed-Methods Study on Risk Mitigation in Generative Models
This study investigates human perceptions of AI-generated responses, specifically focusing on how mitigation strategies reduce harm in generative models. Using a mixed-methods approach with 57 participants, it evaluates responses based on fairness, relevance, faithfulness, and competence. Findings reveal a general preference for mitigated responses, though cultural, linguistic, and experiential factors influence perceptions. The study emphasizes the importance of human-centered evaluation for AI safety and proposes new metrics, highlighting the nuanced ways humans assess AI outputs beyond simple semantic similarity.

Introduction: The Need for AI Mitigation
The rapid uptake of generative AI necessitates ensuring safe, fair, and contextually appropriate outputs, especially given challenges like hallucination and harmful content generation. Despite major efforts for implementing guardrails, human perceptions of these mitigation strategies are largely unknown. This study addresses this gap by investigating human perceptions of AI-generated responses modified by a 'mitigator model' across three key dimensions: mitigation performance, transparency, and metrics. The research aims to contribute to narrowing the socio-technical gap in AI evaluation and propose new metrics for assessing risk mitigation in generative AI.
Methodology: Mixed-Methods Evaluation
A mixed-methods within-subject study with 57 participants evaluated AI-generated responses. Participants from diverse geographic, linguistic, and experiential backgrounds (e.g., native English speakers, South Asian languages, Latin-based languages; varying AI and annotation experience) assessed responses in two phases. Phase 1 involved blind evaluation of mitigated responses for Fairness and Relevance. Phase 2 involved comparative evaluation of original and mitigated responses side-by-side, assessing Fairness, Relevance, Competence, and Faithfulness. Qualitative data from open-ended questions and semi-structured interviews were analyzed using reflexive thematic analysis. The mitigator model itself uses in-context learning to generate bias-free responses by leveraging structured exemplars.
Study Protocol Overview

Final Question: Business Utility of Mitigation Approach
Key Findings: Human Perceptions of AI Mitigation
Quantitatively, participants preferred mitigated responses 66.8% overall. This preference was highest for Fairness (88%) and Competence (66%), and moderate for Relevance (63%). Faithfulness showed no significant preference (51%). Demographic factors like native language and geographic location significantly influenced fairness and relevance evaluations. Notably, exposure to the unmitigated response in Phase 2 led to a statistically significant decrease in scores for the mitigated version, suggesting more critical evaluation. Qualitatively, participants valued mitigation as a guardrail, emphasizing professional form, preservation of core meaning, objectivity, and transparency. They also highlighted the importance of selective mitigation and the challenges posed by vague synthetic prompts.
Insight 1: Harm Removal & Relevance
Models should remove harms, political/moral bias, and judgments while preserving key information and avoiding hallucinations. This ensures that the mitigated content remains directly relevant to the prompt, which participants identified as an essential criterion. When relevance is compromised, other values like fairness become secondary.
- ✓ Remove harms, political bias, moral bias, moral judgments.
- ✓ Preserve key information answering the prompt and avoid hallucinations.
- ✓ Relevance is an essential criterion; it often supersedes other values if compromised.
Insight 2: Linguistic Precision & Coherence
Grammatical and punctuation errors, along with a lack of logical structure, negatively impacted participants' evaluation of fairness, trust, and overall response quality. This highlights human sensitivity to linguistic nuances, which can undermine perceived professionalism and credibility.
- ✓ Grammatical and punctuation errors severely impact perceived Fairness, Trust, and Quality.
- ✓ Lack of logical structure is detrimental to response coherence.
- ✓ Coherence criteria is essential, especially for synthetic data (SDG) is generated.
Insight 3: Objectivity & Factuality
Participants preferred objective and factual responses over generalized or neutral answers, especially when multiple arguments or options were presented. This underscores the need for mitigated responses to be well-grounded in verifiable knowledge and provide decision-useful content.
- ✓ Provide objective and factual responses, avoiding generalizations.
- ✓ Faithfulness and Factuality are critical metrics for preserving key information.
- ✓ Responses must accurately represent real-world information and outputs.
Insight 4: Tone and Professionalism
Figurative language, sarcasm, emotions, opinions, human-like recommendations, first-person sentences, and informal language significantly affected trust and led to perceptions of less fairness. Maintaining a professional and objective tone is crucial for AI systems, unless explicitly invited otherwise.
- ✓ Figurative language, sarcasm, and informal tone reduce trust and perceived fairness.
- ✓ Human-like recommendations and opinions are often viewed as inappropriate.
- ✓ Tone should be a key consideration in Synthetic Data Generation (SDG) outputs.
Insight 5: Selective Mitigation
Mitigation should be precise: removing only harmful content while preserving benign information and avoiding the generation of new, unprompted details. Over-mitigation or alterations to the original meaning negatively impact trust and quality.
- ✓ Remove harms selectively, preserving benign text that is not a risk.
- ✓ Do not generate information not present in the original answer.
- ✓ Selective Mitigation should be a core criterion, including score evaluation for risk detection.
Insight 6: Completeness & Standalone Outputs
Responses are expected to be complete and self-sufficient, providing all necessary information without requiring further queries or context. Incompleteness was a recurring problem flagged by participants.
- ✓ Responses must be complete and self-sufficient.
- ✓ Outputs should be standalone and not require additional user interaction for clarity.
Insight 7: Addressing Value Trade-offs
Model evaluations must account for conflicting values, such as the tension between fairness and relevance or faithfulness. Participants often found themselves balancing these criteria, sometimes favoring less fair but more relevant original responses over mitigated outputs that addressed bias but diverged from the prompt.
- ✓ Model evaluations need to explicitly account for conflicting values (e.g., Fairness vs. Relevance/Faithfulness).
- ✓ A scoring framework should reflect these inherent trade-offs.
- ✓ Users may prioritize relevance and directness over bias mitigation if mitigation compromises core message.
Discussion: Implications for AI Design & Evaluation
The study confirms a general preference for mitigated AI responses, validating human preferences across diverse sociodemographic groups. It provides concrete recommendations for generative AI mitigation techniques, emphasizing harm removal, information preservation, and objective responses. A key insight is the significant influence of participants' native language, AI work experience, and annotation familiarity on their evaluations, underscoring the need for context-specific mitigation. Traditional automated evaluation methods, relying on semantic similarity or machine 'judges', often miss human sensitivity to linguistic nuances, grammar errors, and contextual understanding, which this study highlights as crucial for perceived quality.
Conclusion: Advancing Human-Aligned AI
This research highlights the critical role of human perception in evaluating AI-generated content and the effectiveness of mitigation strategies. The use of mixed-methods is essential for capturing nuanced human insights often missed by purely quantitative or automated approaches. As generative AI becomes integral to human-computer interaction, a deeper dialogue among AI, Human-AI, and HCI researchers is necessary to advance robust, human-aligned AI systems. The findings underscore that contextual understanding and sensitivity to linguistic detail are paramount for effective AI evaluation and development.
