Insights for Personality Simulation
Understanding and replicating human personality is critical for advanced AI applications, from user research to interactive agents.
The InterviewSim Framework
The InterviewSim framework introduces a scalable, interview-grounded approach for personality simulation, combining a robust data collection pipeline with a multi-dimensional evaluation protocol.
Key Evaluation Dimensions
InterviewSim employs four complementary metrics to thoroughly assess simulation fidelity against real human responses across distinct quality dimensions.
0↑ Content Similarity (1-5)Highest achieved by memory-based retrieval
_
0↓ Contradiction Ratio (%)Lowest achieved by chronological-based methods
_
0%↑ Personality Similarity (%)Highest achieved by memory-based retrieval
_
0%↑ MCQ Accuracy (%)Highest achieved by chronological-based methods
Impact of Interview Grounding
The study definitively shows that leveraging real interview data leads to substantially higher fidelity in personality simulation compared to relying on generic biographical information or the model's inherent parametric knowledge.

Contextual Performance Insights
Performance fidelity varies systematically based on the type of question asked and the personality's professional category, highlighting the need for nuanced evaluation.
Social Identity questions (e.g., birth dates, family facts) yield the highest contradiction rates (>17%), requiring precise factual recall. Motivations and Values questions show the lowest contradiction rates (<3.5%). Identity Narrative shows moderate contradiction. This indicates that question type is a strong predictor of difficulty, regardless of method.
Science & Academia personalities have the lowest contradiction rates, likely due to their structured, fact-focused interviews. Film & Television and Music personalities exhibit the highest contradiction rates, as their interviews are often more anecdotal and cover diverse topics over time, making consistent factual representation harder.
Knowledge Retention Breakthrough
The MCQ evaluation revealed that chronological-based methods significantly improve factual knowledge retention and reduce susceptibility to deceptive distractors, showcasing robust gains across diverse data regimes.
