| Challenge: | Pretrained LLMs fail to capture behavioral diversity of target populations due to inherent variability across individuals and groups. |
| Approach: | They propose a probabilistic prompting method that aligns LLM responses with the target population. |
| Outcome: | Experiments show that the proposed method outperforms competing methods in alignment and diversity metrics. |
