The two waves measured days of use differently. March asked a single overall question whose response options were these three groups, while August asked day counts for each service separately, which we collapsed into the same groups.
【方法】调查方法存在重要差异：三月询问整体使用情况，而八月询问每个服务的单独使用天数。这种差异可能导致数据解释偏差，因为八月的方法可能低估实际使用频率（例如，使用多个服务的人可能被计数为使用天数而非总使用次数）。
We polled the American electorate in August as part of our broader work on datacenter sentiment, energy prices, and frontier labs. The full survey is part of our Tokenomics model, which focuses on the economics, adoption, and demand dynamics of AI and datacenter infrastructure.
【方法】作者提到他们进行的民意调查是其更广泛数据中心情绪研究的一部分，展示了其研究方法的多元性。结合民意调查与经济模型分析，表明他们不仅关注技术层面，还考虑社会和政治因素，这种综合方法提供了更全面的分析视角。
We present results from a survey of 1,260 social scientists about AI and coding agent use, fielded in February and March 2026.
这个样本量(1,260)对于社会科学研究来说相当可观，提供了足够的数据基础进行分析。然而，文章也提到这不是代表性样本，因为受访者是受邀参与AI工作流程研究的，可能导致结果偏向于对AI工具更感兴趣的研究者。这一数据点表明研究结果可能存在选择偏差。

telephone interviews with 37 participants
I have to wonder at telephone samples of this age group given the propensity of youth to not communicate via voice phone.
