Research brief

在进行生成式AI受众模拟调研时,哪种虚拟样本量策略最能有效平衡子群交叉制表的稳定性与方差控制?请评估以下策略的合理性:盲目追求数万级别样本以覆盖所有边缘细分群体、采用100到300个代理的轻量级面板进行快速概念筛选、将样本量锚定在基于人口普查微观数据构建的固定规模基准池、以及完全依赖不设上限的重复采样来抵消模型随机噪声。

Anchoring sample sizes to a fixed benchmark pool constructed from census microdata audience

Researchers favoring census-anchored sample sizes for generative AI simulations are primarily concentrated in the Northeast and South regions.

183 / 200 respondents91.5%

This segment shows a strong preference for using census-based microdata to anchor sample sizes for improved simulation stability.

The audience is characterized by a higher concentration of individuals aged 45-54 and those holding master's degrees compared to the general baseline.
