腾讯混元数字人团队发布Moral RolePlay基准，揭秘大模型的「道德困境」

Core Insights - The article discusses the limitations of current AI models in portraying complex moral characters, particularly villains, highlighting a significant shortcoming in creative generation and understanding of social psychology [3][4]. Group 1: Moral RolePlay Framework - The "Moral RolePlay" benchmark developed by Tencent and Sun Yat-sen University systematically evaluates AI's ability to simulate diverse moral roles, especially antagonists [3][10]. - The evaluation framework includes four character categories ranging from "Moral Paragon" to "Villain," with 800 carefully selected character profiles and 77 personality traits to assess the consistency and nuance of AI's persona expression [10][12]. Group 2: AI Performance Evaluation - A large-scale assessment of 18 mainstream AI models revealed that general conversational ability does not correlate with the ability to portray villains effectively [21][22]. - The performance scores for villain roles dropped significantly from Level 1 (3.21) to Level 4 (2.62), indicating a clear decline in the models' ability to express selfish behaviors, which was identified as a major challenge [22][23]. Group 3: Insights on Negative Traits - Negative traits were found to incur the highest average penalties in performance evaluations, with traits like "Hypocritical" and "Deceitful" leading to the most significant score deductions [29][31]. - The analysis indicates that AI struggles to authentically simulate negative characteristics due to conflicts with its training objectives focused on being helpful and sincere [32]. Group 4: Future Directions - The research highlights a critical limitation in current AI alignment methods, suggesting that overly "good" models trained for safety cannot accurately simulate the full spectrum of human psychology [38]. - Future alignment technologies need to be more context-aware, capable of distinguishing between generating harmful content and simulating antagonistic roles in fictional contexts [38].
