LLM-Enhanced Modeling of Social Desirability-Aware Forced-Choice Personality Assessment
Revolutionizing Personality Assessment: AI-Powered Bias Mitigation for Trustworthy Human-Centered AI
Our innovative Social Desirability-aware Forced-Choice Diagnosis (SDFCD) leverages Large Language Models (LLMs) to automatically quantify social desirability (SD) biases, enabling more accurate and interpretable personality assessments in high-stakes environments. This advanced approach moves beyond traditional methods, offering a robust solution for human-centered AI.
Executive Impact: Enhanced Precision & Trust in Human-Centered AI
In high-stakes scenarios like talent acquisition or clinical diagnosis, the integrity of personality assessments is paramount. Social desirability bias often compromises validity. SDFCD addresses this by providing a scalable, fine-grained, and bias-aware diagnostic framework. Our research demonstrates significant improvements in accuracy and interpretability, delivering more reliable insights for critical decision-making.

Highest LLM-Human SD Rating Correlation (Pearson r)
Large Language Models, particularly Deepseek-v3, demonstrate strong convergent validity with human expert ratings for social desirability (r=0.859). This confirms their ability to capture fine-grained semantic cues for SD at scale, providing a consistent and interpretable basis for assessment.
| Feature | Human Expert Ratings | LLM-Generated Ratings |
|---|---|---|
| Granularity | Coarse-grained (discrete Likert) | Fine-grained (continuous scale) |
| Scalability | Labor-intensive, costly, subjective | Automated, scalable, consistent, objective proxy |
| Entropy (BFT) | 0.506 (Less dispersed) | 0.762 (More dispersed, Deepseek-v3) |
| Prompt Sensitivity | N/A | High stability across neutral and high-stakes contexts |

SD-Aware Diagnosis Module
The SDFCD framework integrates LLM-generated social desirability ratings with a novel neural network architecture. It models respondent and item SD traits, separating honest and faking response pathways to enhance diagnostic accuracy and interpretability.
| Model | PRA (Baseline) | PRA (SD-Aware) | LRA (Baseline) | LRA (SD-Aware) |
|---|---|---|---|---|
| FCNCD | 68.38% | 69.52% | 34.07% | 35.96% |
| GTUM | 64.53% | 68.08% | 29.95% | 34.43% |
| 2PLM-RANK | 63.72% | 68.04% | 28.85% | 34.65% |
| FMM | 64.72% | 67.80% | 30.24% | 34.26% |
Across all baseline models, incorporating the SD-aware module consistently improved diagnostic performance (PRA and LRA), especially under faking conditions. This demonstrates SDFCD's effectiveness in mitigating social desirability bias.

FCNCD PRA Improvement (Absolute % points)
The integration of SD-aware modules significantly improves predictive accuracy, with FCNCD showing an absolute PRA gain of 1.14% under faking conditions, highlighting the value of explicit bias modeling.
Detecting and Correcting SD Bias
SDFCD provides clear insights into how social desirability bias impacts responses. In our analysis, we observe a significant increase in both the SD weight (πs,e) and SD effect (πs,eŷSD) under faking conditions compared to honest conditions.
For instance, when a respondent was instructed to fake, item 22 ('I recover quickly from stress and illness,' SD: 0.82) shifted from Rank 2 to Rank 3 in Block 4, while item 23 ('I am very sensitive,' SD: 0.58) dropped from Rank 3 to Rank 1. This shows a clear tendency to rank more socially desirable items higher under faking.
Crucially, SDFCD effectively disentangles these SD-driven response shifts from the respondent's true traits. This results in more stable and consistent trait estimates across honest and faking conditions, with a cross-condition Pearson correlation (rmean) of 0.362 for SDFCD compared to just 0.127 for FCNCD.
| Component Removed | BFT_Fake PRA (SD-Aware) | BFT_Fake LRA (SD-Aware) |
|---|---|---|
| SDFCD (Full Model) | 69.52% | 35.96% |
| LLM SD Ratings | 68.17% | 34.12% |
| Item-level SD Modeling | 68.62% | 35.10% |
| Student-level SD Traits | 68.69% | 34.81% |
| SD Loss Constraint | 68.65% | 34.97% |
Each component of SDFCD, including LLM-rated SD, item-level and student-level SD modeling, and the SD loss regularization, significantly contributes to the model's robustness and predictive accuracy, demonstrating the integrity of the design.
