We test standard demographic-persona methods against every real intersectional subgroup across 15 waves of Pew&apos;s American Trends Panel -- 21 million simulated response distributions from eight models. In real respondents, subgroup opinion is approximately the additive sum of its single-identity components, yet grows 2.5x more distinctive as identities intersect. Simulated respondents show no such composition: a single feature explains a two-feature persona&apos;s responses better than the additive combination in 75-82% of subgroups, and a third feature adds… — Source: arXiv</description><pubDate>Mon, 24 Aug 2026 09:07:51 GMT</pubDate><category>Research</category></item><item><title>Beyond the Survey: How Synthetic Research Is Changing Consumer Insight</title><link>https://europeanbusinessreview.com/beyond-the-survey-how-synthetic-research-is-changing-consumer-insight</link><guid isPermaLink="true">https://europeanbusinessreview.com/beyond-the-survey-how-synthetic-research-is-changing-consumer-insight</guid><description>Source: europeanbusinessreview.com</description><pubDate>Mon, 24 Aug 2026 07:00:00 GMT</pubDate><category>News</category></item></channel></rss>
